WHAT IS THE PRODUCT
INTERFACE?
Chapter 1
Introduction
The PowerLogic Product Interface for MICROLOGIC circuit breakers, together
with MICROLOGIC Series III A/B circuit breakers, provides an economical means
to perform remote current monitoring, without the need for additional current
transformers or metering equipment. In addition, the Product Interface reports a
wealth of valuable historical trip data and circuit breaker data from MICROLOGIC
Series III A/B circuit breakers. Table 1-1 lists the available data.
The Product Interface can be mounted in QED switchboards to enable local and
remote monitoring of circuit breaker data. The data from up to 32 circuit breakers
can be displayed using a PowerLogic System Display for MICROLOGIC Circuit
Breakers (SD-100/SD-120), or an IBM PC compatible computer equipped with
PowerLogic software. Using the Square D SY/NET network, personal computers
running PowerLogic software can monitor virtually any number of MICROLOGIC
circuit breakers, PowerLogic Circuit Monitors, Lifegard Model 85 Transformer
Temperature Controllers, and other compatible devices.

During troubleshooting stages, the trip unit’s historical data, reported by the
Product Interface, can aid in reducing further system down-time and help in
preventing future electrical outages. Last trip data provided includes Cause of Last
Trip, Date and Time of Last Trip, and Phase and Ground Fault Current Magnitudes
at time of trip.
And, to aid in preventative maintenance planning, the Product Interface reports a
summary of the total number of trips for overload, short circuit and ground fault.
Circuit Breaker Data and Trip Settings
Circuit breaker data available through the Product Interface includes the type of
circuit breaker, the sensor rating and the plug rating. In addition, the trip unit delay
and pickup settings for Long Time, Short Time, Instantaneous, and Ground Fault
are provided. This data allows you to compare the settings to existing records, to
determine tampering or inadvertent changes to the protection functions. And using
the System Display for MICROLOGIC circuit breakers with optional printer port
(SD-120), you can send the data to a serial printer creating a permanent record of
the circuit breaker’s settings.

Specifications and Applications
Chapter2–Specificationsand
The PowerLogic Product Interface for MICROLOGIC Circuit Breakers (PIF-3) is
housed in an aluminum case designed to be mounted in power equipment. The
compact Product Interface mounts in low-voltage switchboards and other small
spaces. Figure 2-3 shows the overall dimensions.
The terminal strip connections for communications cables and control power are
housed behind a protective cover held in place by three captive screws. This cover
can be removed for connection to additional circuit breakers, for changing the
control power fuse, or for inspection of installed wiring. The protective cover
must be securely attached at all other times. This safeguard is designed to
prevent inadvertent damage to the connections.
The Product Interface provides eight removable 4-position terminal plugs for
connection of up to eight MICROLOGIC Series IIIA/B circuit breakers. Each circuit
breaker must be connected to a communications adapter (CIM3F) for isolation and
power. Each communications adapter is then connected to the appropriate terminal
strip position on the side of the Product Interface. (See Figure 2-1).

Specifications and Applications
Also located on the side of the Product Interface are a ground terminal, a control
power terminal strip connector, and a control power fuse. (See Figure 2-1). The
Control power is fused with a 2A 250V Slow Blow fuse.
A flush mounted door on the front of the Product Interface provides access to a
number of switches. (See Figure 2-2). Two ten position rotary switches are used to
set the Product Interface base communications address. Another ten position rotary
switch is used to set the Product Interface baud rate. A 16 position rotary switch is
used to specify the number of circuit breakers connected to the Product Interface.
A push button switch is used to reset the Product Interface. Chapter 4 Setup and
Operation provides instructions for using these switches. Also housed behind the
door is a lithium battery. This battery is used to maintain the Product Interface clock
and non-volatile RAM in the event of a power loss.
The front of the Product Interface contains three LEDs. Two green LEDs, labeled
12V OK and 5V OK, are lit when the Product Interface is receiving adequate control
power. The red LED, labeled Battery Low, is a warning light for the lithium battery.
When the red LED is lit, the battery voltage is low, and the battery must be replaced.
See Chapter 5 Maintenance and Troubleshooting for instructions on replacing
the battery.

MOUNTING THE
PRODUCT INTERFACE
The Product Interface is designed to be mounted in power equipment. When
choosing a mounting location, consider the following points:
•
Mount the Product Interface no more than 50 feet from any circuit breaker
connected to it.
•
Mount the Product Interface in a location that allows access to the door on
its front cover.
•
Allow adequate clearance on the side of the Product Interface for wiring
connections.
•
Mount the Product Interface to allow for adequate heat dissipation. If
environmental conditions produce temperatures higher than the operating
range, (0° C to +70° C), make provisions to bring the ambient temperature
to 70° C or less.
•
Refer to Figure 2-3 for Product Interface Dimensions.
To prepare the panel for installation, drill four 1/4" mounting holes. Figure 3-1
shows the drilling pattern.

CAUTION
HAZARD OF EQUIPMENT DAMAGE.
Do not connect the Product Interface directly to circuit breakers.
The Product Interface must be connected to Communications
Adapters (CIM3F) which are in turn connected to circuit breakers.
Failure to observe this precaution could result
in damage to the circuit breaker.
The Product Interface provides eight removable 4-position terminal plugs for
connection of up to eight MICROLOGIC Series III A/B circuit breakers using
MICROLOGIC Communications Adapters (catalog no. CIM3F). Each
MICROLOGIC circuit breaker is first wired to a Communications Adapter which
is then connected to the appropriate terminal strip position on the side of the Product
Interface. Figure 3-2 illustrates this point.

For instructions on connecting the Communications Adapter to a circuit breaker,
refer to the instruction bulletin for the Communications Adapter (#48040-720-01).
To wire a Communications Adapter to the Product Interface, complete the following steps:
1. The CIM3F Communications Adapter comes with a 10 foot communication cable. One end of the cable has a modular connector which plugs into
the Communications Adapter. Plug this modular connector into the Communications Adapter.
2. If the 10 foot cable is too long, cut the cable to the desired length. If the 10
foot cable is not long enough, use Manhattan M3802 cable or equivalent
(50 ft max).
3. The other end of the 10 foot cable has four flying leads. Expose the four
cable conductors by stripping the cable sheath back 2 inches. Then strip the
insulation for each conductor back 1/4 inch.
Page 3-2

Chapter 3
Installation
Bulletin No. 3050IM9101
December 31, 1991
4. Inspect the stripped ends for stray wires to minimize the possibility of
shorts across terminals.
5. The Product Interface has eight removable 4-position terminal plugs for
connecting Communications Adapters. The terminal jacks are labeled
“ADD+0, ADD+1, ADD+2....ADD+8”. Connect the flying leads on the 10
foot cable to the lowest available terminal plug. For example, wire the first
Communications Adapter to plug “ADD+0”, the second to plug “ADD+1”,
the third to plug “ADD+2”, and so on. Follow the color code shown in
Table 3-1. This color code illustration also appears on the label inside the
terminal strip protective cover. Figure 3-3 illustrates the connections.
IMPORTANT: Follow the color codes carefully. Failure to do so will result in
improper operation or damage to the Communications Adapter.

CONNECTING TO THE
POWERLOGIC
COMMUNICATIONS LINK
Chapter 3
Installation
As in all other PowerLogic devices, the Product Interface uses an industry standard
RS-485 (RS-422 compatible) electrical interface for data communications. Multiple Product Interfaces, Circuit Monitors, and other PowerLogic devices can be
daisy-chained together on a single PowerLogic communications link. Figure
3-4 shows multiple device types on a communications link.
The Product Interface can be connected to a communications port on:
•
A PowerLogic System Display for MICROLOGIC Circuit Breakers
•
A PowerLogic Network Interface Module (PNIM)
•
A personal computer equipped with a SY/LINK PC interface board
All PowerLogic devices have an RS-485 communications port for connection to a
PowerLogic communications link. The Product Interface uses a removable, fiveposition terminal plug labeled “RS485 COMMS” for this purpose. (See Figure 3-5).
As in all other PowerLogic devices, the Product Interface requires a communication cable containing two shielded twisted pairs (Belden 8723 or equivalent).
Communication cables are daisy-chained from the Product Interface’s RS-485
communications terminals to the matching RS-485 communications terminals of
the next device. That is, SHLD is wired to SHLD, OUT- to OUT-, OUT+ to OUT+,
IN- to IN-, and IN+ to IN+.
If the Product Interface is the last device on the communications link, it must be
terminated using a Multipoint Communications Terminator (MCT-485). See
Terminating the Communications Link below for termination instructions. If the
Product Interface is the first device on the link, it must be connected to a

See Biasing the Communications Link below for biasing instructions. If the
Product Interface is “buried” in the communications link, complete the following
steps:
1. Strip back the cable sheath 2 inches on both ends of the communications
cable. Then strip back the insulation for each conductor 1/4 inch.
2. Inspect the stripped ends for stray wires to minimize the possibility of
shorts across terminals.
3. Connect one wire to the IN+ terminal on the Product Interface’s RS-485
5-position terminal block. Connect the other end of the same wire to the
IN+ terminal of the next device.
4. Repeat step 3, connecting the IN- terminal on the Product Interface to the
IN- terminal on the next device, the OUT+ terminal on the Product
Interface to the OUT+ terminal on the next device, and so on.
For example, to wire a Product Interface to a Circuit Monitor, connect the SHLD
terminal on the Product Interface to the SHLD terminal on the Circuit Monitor,
connect the OUT- terminal on the Product Interface to the OUT- terminal on the
Circuit Monitor, connect the OUT+ terminal on the Product Interface to the OUT+
terminal on the Circuit Monitor, and so on. Figure 3-6 illustrates this example.

Biasing the Communications To ensure reliable communications, the PowerLogic communications link must be
Link
biased. This is done using a biasing device called a Multipoint Communications
Adapter (MCA-485). The adapter is placed between the first device on the link and
the communications port of the System Display, PNIM, or SY/LINK card. Figure
3-7 illustrates the installation of the adapter when the first device on the link is a
Product Interface. If the first device on the link is not a Product Interface, refer to
the first device’s instruction bulletin for biasing instructions.
To connect the Product Interface as the first device on the PowerLogic communications link, you will need the following items:
•
One PowerLogic Multipoint Communications Adapter (3090 MCA-485).
(This is not included with the Product Interface and must be purchased
separately).
•
One PowerLogic cable 3090 CAB-107. (This is not included with the
Product Interface and must be purchased separately).
•
A five position terminal block—1 provided with each Product Interface.
•
Belden 8723 or equivalent cable. (This is not included with the Product
Interface and must be purchased separately).
Figure 3-7 illustrates the wiring connections. Refer to this figure when completing

Terminating the
Communications Link
Chapter 3
Installation
To ensure reliable communications, the last device on a PowerLogic communications link must be terminated. Figure 3-8 illustrates terminator placement when the
last device on the link is a Product Interface for MICROLOGIC Circuit Breakers. If
the last device is not a Product Interface, refer to the last device’s instruction
bulletin for termination instructions.
NOTE
If a communications link contains only a single device, it must be
terminated. If a link contains multiple devices, as in Figure 3-8, only
the last device must be terminated.
To connect the Product Interface as the last device on the PowerLogic communications link, you’ll need the following items:
•
One PowerLogic RS-485 Multipoint Communications Terminator (3090
MCT-485). (This is not included with the Product Interface and must be
purchased separately).
•
A five position terminal block—1 provided with each Product Interface.
•
Belden 8723 or equivalent cable. (Not included).

CONNECTING CONTROL
POWER
Chapter 3
Installation
The Product Interface accepts either AC or DC control power. Control power
connections are made to a terminal strip on the side of the Product Interface. (See
Figure 3-10). The control power is fused with a 2.0 AMP slow blow fuse. See
Chapter 5 for instructions on changing the fuse.
IMPORTANT: In all wiring installations, wire the Product Interface according to
all applicable electrical codes.
AC Installation
The Product Interface requires 90-132 VAC control power at 50/60 Hz. Connect
the power cable to the Line (L), Neutral (N), and Ground (G) terminals as marked
on the Product Interface. Use a properly sized disconnect switch as a means to
remove control power from the Product Interface.
DC Installation
The Product Interface requires 110 - 170VDC power. Connect the power cable to
the positive (+) and negative (-) terminals as marked on the Product Interface.
Important: Observe proper polarity when connecting DC power. Use a properly
sized disconnect switch as a means to remove control power from the Product
Interface.
GROUNDING THE
PRODUCT INTERFACE
CHASSIS
The chassis ground terminal is located on the side of the Product Interface. (See
Figure 3-10). Connect the chassis ground terminal to a building column or
grounding electrode determined to be a “true earth” ground. Ground wire should
be #14 gauge minimum.

Chapter4–SetupandOperation
The Product Interface has five switches located behind its front access door. These
switches are used to set its baud rate, set its base address, set the number of circuit
breakers connected to it, and reset the Product Interface. Figure 4-1 shows the
switch locations. A label on the back of the access door also shows the switch
locations and their functions. This chapter describes the purpose and use of each
switch.
The Product Interface must be reset each time a change is made to the address, baud
rate, or number of connected circuit breakers switch settings. There are two ways
to reset the Product Interface: Hardware Reset, and Software (remote) Reset.
To perform a hardware reset, press the Reset button located behind the access door
on the front of the Product Interface. (See Figure 4-1). For instructions on
performing a software reset using PowerLogic software, refer to the instruction
bulletin accompanying the software.
NOTE
Reset the Product Interface after changing a switch setting. If you
change a switch setting but fail to perform a reset, the Product
Interface will not act on the new switch setting.

Setup and Operation
The Product Interface baud rate must be set to match the baud rate of the device(s)
it is connected to. In other words, all devices on the PowerLogic communications
link must be set to the same baud rate. For example, if two Circuit Monitors and one
Product Interface are daisy-chained to a PNIM, both Circuit Monitors, the Product
Interface, and the PNIM port must be set to the same baud rate.
The baud rate switch is located behind the access door on the front of the Product
Interface. (See Figure 4-1). The baud rate switch settings are clearly identified on
a label inside the access door. Table 4-1 repeats the baud rate switch settings.
To set the baud rate, complete the following steps:
1. Insert a miniature, flat-bladed screwdriver into the arrow in the center of
the baud rate switch.
2. Rotate the switch until the arrow points to the number that corresponds to
the desired baud rate. For example, to select 19200 baud, rotate the arrow
to switch position 5.
3. Press the Reset button. This forces the Product Interface to recognize the
new baud rate setting.
NOTE: The Product Interface can also be reset by issuing a reset command
using PowerLogic application software. See Resetting the Product
Interface, in this chapter, for more information.
UNDERSTANDING
ADDRESSING
Any single PowerLogic communications link can support up to 32 individual
device addresses. Therefore, a maximum of 32 circuit breakers can be monitored
on a single PowerLogic communications link. Each Product Interface can support
from 1 to 8 circuit breakers. The maximum number of Product Interfaces that can
be connected to a PowerLogic communications link is tied to this 32 circuit breaker
limit.
For example, a PowerLogic communications link could contain four Product
Interfaces each connected to eight circuit breakers. Or a communications link could
contain eight Product Interfaces each connected to only four circuit breakers. Or a
communications link could contain 16 Product Interfaces each connected to only
two circuit breakers.
Each Product Interface on a communications link must be assigned a base
communications address. The Product Interface’s base address is assigned using
the two ten-position rotary switches housed behind the door on its front. (See
Setting the Base Communications Address below for instructions on setting the
address switches).
Page 4-2
 1991 Square D. All Rights Reserved
Chapter 4
Setup and Operation
Bulletin No. 3050IM9101
December 31, 1991
Each Product Interface must also be told how many circuit breakers are connected
to it. The # of connected circuit breakers is set using the sixteen position rotary
switch also housed behind the door on the front of the Product Interface. (See
Setting the # of Connected Circuit Breakers below for instructions on setting the
switch).
The base address tells the Product Interface which communication address to use
for the first circuit breaker connected to it. The # of connected circuit breakers
switch tells the Product Interface how many communication addresses to assign to
its circuit breakers. For example, if a Product Interface’s base address is 01, and the
# of connected circuit breakers switch is set to 05, then the Product Interface assigns
addresses 01, 02, 03, 04, and 05 to its circuit breakers. Or, if a Product Interface’s
base address is 07, and the # of connected circuit breakers switch is set to 03, then
the Product Interface assigns addresses 07, 08, and 09 to its circuit breakers.
Circuit breakers are connected to the Product Interface via eight removable 4position terminal plugs. (See Chapter 3 for connection instructions). The terminal
plugs are labeled “ADD+0”, “ADD+1”, “ADD+2”, . . . , “ADD+8”. The circuit
breaker connected to position ADD+0 is assigned the Product Interface base
address. The circuit breaker connected to position ADD+1 is assigned the base
address+1. The circuit breaker connected to position ADD+2 is assigned the base
address+2, and so on.
For example, assume that a Product Interface’s base address is 09, and the # of
connected circuit breakers switch is set to 03. Then the circuit breaker connected
to the plug labeled ADD+0 is assigned the address 09. The circuit breaker
connected to the plug labeled ADD+1 is assigned the address 10. And the circuit
breaker connected to the plug labeled ADD+2 is assigned the address 11.
Choosing a Base
Communications Address
When choosing the base address for a Product Interface, remember that each circuit
breaker on the communications link must have a unique address. Duplicate
addresses on a PowerLogic communications link will cause communication errors.
For example, assume that the base address of a Product Interface is set to 01, and
the # of connected circuit breakers switch is set to 04. The Product Interface assigns
addresses 01, 02, 03, and 04 to its circuit breakers. These addresses can’t be used
again on the same PowerLogic communications link. The next available address is
05.
You could set the base address of the second Product Interface to 05. But assume
that you want to connect a fifth circuit breaker to Product Interface 01. To do this
you must change the # of connected circuit breakers switch from 04 to 05. The
Product Interface then assigns the address 05 to the fifth circuit breaker. But if the
base address of the second Product Interface is 05, you’ve created a duplicate
 1991 Square D. All Rights Reserved

Chapter 4
Setup and Operation
address. This will cause communication errors. To correct the error, you must
change the base address of the second Product Interface to 06 or higher. The
addresses of the circuit breakers connected to the second Product Interface will be
renumbered according to its new base address.
To prevent this from happening, you can assign base addresses with expansion in
mind. For example, assume that you have a system with two Product Interfaces,
each connected to four circuit breakers. To provide for expansion, you could assign
the first Product Interface the base address 01 and set the # of connected circuit
breakers switch to 04. Its circuit breakers would be assigned the addresses 01, 02,
03, and 04. You could then assign the second Product Interface the base address 09
and set the # of connected circuit breakers switch to 04. Its circuit breakers would
be assigned the address 09, 10, 11, and 12.
By doing this, you have left addresses 05, 06, 07, and 08 unused. Then, when you
add another circuit breaker to Product Interface 01, you can change the # of
connected circuit breakers switch to 05. The Product Interface will assign the
circuit breaker the available address 05. Figure 4-2 illustrates this example.
Other Important Addressing
Considerations
The bullet items below list several other items to consider when choosing Product
Interface base addresses:
•
•
Page 4-4
Each PowerLogic communications link must have one device whose
address is “01.”
-
If a communications link contains several daisy-chained Product
Interfaces (and no other PowerLogic devices), one Product Interface must be assigned the base address “01.”
-
If a communications link contains only one PowerLogic device, a
Product Interface, its base address must be “01.”
-
If a communications link contains Product Interfaces and other
PowerLogic devices, and a System Display for Micrologic Circuit
Breakers (SD-100/SD-120) is used to display circuit breaker data,
then device “01” must be a Product Interface. Figure 3-4 shows a
systems where this rule applies.
When Product Interfaces are connected to a PowerLogic Network Interface Module (PNIM), the PNIM should be assigned either the address 0, or
an address above the highest address assigned to any circuit breaker. For
example, if a communications link has four Product Interfaces and 32
circuit breakers addressed as 1-32, the PNIM address should be either 0 or
33 or higher.

SETTING THE BASE
COMMUNICATIONS
ADDRESS
Each Product Interface must be assigned a base communications address. The
Product Interface uses the base address to assign addresses to the circuit breakers
connected to it. Before attempting to set the base address, be sure and read the
section Understanding Addressing above.
The base address is set using two ten position rotary switches located behind the
door on the front of the Product Interface. (See Figure 4-1). The address switch
closest to the Baud Rate switch sets the ones digit. The address switch closest to the
Reset switch sets the tens digit.
To set the base address, complete the following steps:
1. Insert a miniature, flat-bladed screwdriver into the arrow in the center of
the ones switch.
2. Rotate the switch until the arrow points to the desired number.
3. Insert a miniature, flat-bladed screwdriver into the arrow in the center of
the tens switch.
4. Rotate the tens switch until the arrow points to the desired number, from
1 to 8. Position 9 is not a valid setting.
5. Press the Reset button. This forces the Product Interface to recognize the
new switch setting.
NOTE: The Product Interface can also be reset by issuing a reset command
using PowerLogic application software. See Resetting the Product
Interface, in this chapter, for more information.

SETTING THE NUMBER
OF CONNECTED CIRCUIT
BREAKERS
Chapter 4
Setup and Operation
The number of circuit breakers connected to the Product Interface is set using the
sixteen position rotary switch located above the Address switches. (See Figure
4-1). This switch tells the Product Interface how many addresses it must assign to
its connected circuit breakers.
For example, if the Product Interface has a base address of 10, and this switch is set
to 4, then the Product Interface reserves addresses 10, 11, 12, and 13 for the circuit
breakers connected to it. The circuit breaker connected to the terminal labeled
ADD+0 is assigned the address 10. The circuit breaker connected to the terminal
labeled ADD+1 is assigned the address 11. The circuit breaker connected to the
terminal labeled ADD+2 is assigned the address 12. And the circuit breaker
connected to the terminal labeled ADD+3 is assigned the address 13. See Understanding Addressing above for more on addressing.
This switch should always match the exact number of connected circuit breakers.
If a Product Interface is connected to four circuit breakers, but the # of connected
circuit breakers switch is set to 3, then the Product Interface will not recognize the
fourth circuit breaker.
To set the number of connected circuit breakers, complete the following steps:
1. Insert a miniature, flat-bladed screwdriver into the arrow in the center of
the 16 position switch.
2. Rotate the switch until the arrow points to the number of connected circuit
breakers, from 1 to 8.
Note: Switch positions 9, A, B, C, D, and E are reserved. If the switch is
inadvertently set to one of these settings, the Product Interface defaults to
8 connected circuit breakers and operates accordingly. Switch positions F
and 0 are reserved for specific functions. If the switch is set to either of these
positions, the Product Interface will not operate.
3. Press the Reset button. This forces the Product Interface to recognize the
new switch setting.
Note: The Product Interface can also be reset by issuing a reset command
using PowerLogic application software. See Resetting the Product
Interface, in this chapter, for more information.

INSTALLING THE
BATTERY
Bulletin No. 3050IM9101
December 31, 1991
The Product Interface uses a long-life lithium battery to maintain the clock and nonvolatile RAM in the event of a control power loss. The user must install the battery
before initial start-up of the Product Interface. For maximum battery life, do not
install the battery until you are ready to apply control power to the Product
Interface.
The battery is located behind the door on the front of the Product Interface. To
install the battery, open the door and press the battery into the battery clip. Make
sure that the “+” end of the battery matches the “+” symbol on the battery clip.
INITIAL START-UP
Before starting the Product Interface, review Chapter 3 and Chapter 4. Verify that
all external wiring is connected according to color codes. Inspect for stray wires and
short conditions. Check the baud rate and address settings. Be sure that the Product
Interface baud rate matches the baud rate of all other devices on the PowerLogic
communications link. Verify that the addresses of the circuit breakers connected to
the Product Interface are unique. Check the # of connected circuit breakers switch
to make sure that it is set to the actual number of connected circuit breakers.
Replace the terminal strip protective cover. The cover should remain in place to
prevent inadvertent damage to wiring connections. Close and secure the front
access door.
After verifying proper installation and setup, apply control power to the Product
Interface. The two green LEDs on the front of the enclosure should light indicating
that the Product Interface is functioning properly. The red LED on the front of the
enclosure is the low battery warning indicator and should not light. If the red light
comes on, check the battery to see that it is seated properly. If one or both of the
green LEDs does not light, or the red LED does light and you’ve verified that the
battery is properly seated, refer to Chapter 5 - Maintenance and Troubleshooting for troubleshooting tips.
SETTING THE CLOCK
AND ASSIGNING LABELS
AND NAMEPLATES
The final steps required to set up the Product Interface for operation are (1) setting
the Product Interface Clock, and (2) assigning a Label and Nameplate for each
circuit breaker.
The Product Interface clock is used to record the time and date of important events
such as the Time and Date of Last Trip. The Product Interface’s lithium battery
maintains the clock in the event of a control power loss.

The label is a four character alpha-numeric string. The PowerLogic Product
Communications Software and other PowerLogic products display the label to help
identify the circuit breaker being viewed. A typical label might be “CB-1,” where
“CB” indicates that the device being viewed is a circuit breaker, and “1” is the
circuit breaker’s address.
The nameplate is 16 character alpha-numeric string. The PowerLogic Product
Communications Software and other PowerLogic products display the nameplate
to help identify the circuit breaker being viewed. For example, if a circuit breaker
feeds the welder on production line 3, the nameplate might be “Welder Line 3.”

in severe personal injury or death!
REPLACING THE
LITHIUM BATTERY
The Product Interface is equipped with a long-life lithium battery. The battery
maintains the Product Interface clock and non-volatile RAM in the event of a
control power loss. The battery is located behind the flush mounted door on the
front of the Product Interface.
The front of the Product Interface enclosure has three LEDs. The red LED, labeled
Battery Low, is a warning light for lithium battery. When the red LED is lit, the
battery voltage is low, indicating the battery must be replaced.
The battery can be changed while the Product Interface is operating. To change the
battery, open the door on the front of the Product Interface. Remove the old battery
and replace it with a new battery. Make sure that the “+” end of the battery matches
the “+” symbol on the battery holder.
NOTE
When replacing the battery, use extreme care not to touch the
circuit board. — For maximum battery life, remove the battery when
storing the Product Interface for extended periods of time.

storage registers. Table A-2 provides a listing of the registers. The table has five
column headings: PIF Reg, CM Reg, R/W, Save, and Description. The column
headings are described below.
PIF Reg -
This column shows the Product Interface register number.
CM Reg -
Some of the registers in the Product Interface store data that is also
available in the PowerLogic Circuit Monitor. These registers have
an associated Circuit Monitor “shadow” register, listed in the CM
Reg column. Each “shadow” register duplicates the data stored in
the associated PIF register. For example, Product Interface register
6201 stores Phase A Current. The Circuit Monitor stores Phase A
Current in register 3. So if you look at register 6201 in this
appendix, you will see that it lists register 3 in the CM Reg column.
This means that you can read Phase A Current from either register
6201 or register 3. Both registers return the same data.
R/W -
An R is shown in this column if the register can only be read, but
not written. If the register can be read and written, R/W is shown
in this column.
Save -
This column describes the action taken by the Product Interface
upon loss of power. When power is restored, one of three
conditions exist for each register:
S (SAVE) =
The value that existed before power loss is
saved.
U (UPDATE) =The value that existed before power loss is
replaced by the present value.
Z (ZERO) = The value that existed before power loss is
replaced by zero.
Description - This column provides a description of the register contents.
IMPORTANT NOTES
•
Registers 0001 - 5999 and 6400 - 8171 are undefined, except for the registers
presented as Circuit Monitor shadow registers. (The shadow registers are listed
in the “CM Reg” column of Table A-2). Undefined registers return a value of
zero when read. A write to an undefined register does nothing. The Circuit
Monitor shadow registers will return valid data when read.
•
Product Interface register numbers 6000 - 6099 and 8172 - 8192 are Global for
all active trip units on the Interface. Reading a global register, using all active
trip unit addresses, returns identical results. Writing to a global register, using
any one of the trip unit addresses, updates the register value of all of the trip
units.

Short Circuit and Ground Fault Restraint Inputs. A “high” restraint
input indicates that a fault has occured but the addressed circuit breaker
is in “restraint”; i.e., it is delayed to allow the downstream breaker closest
to the fault to react, thereby limiting the zone of power interruption. Since
the restraint input resets automatically when the fault is cleared, the user
will not typically see this condition. Bit map follows:
Bit 1 = 1 - Short Circuit Restraint Input high
Bit 2 = 1 - Ground Fault Restraint Input high
Bits 3 through 16 are reserved for future use.
(Bit setting = 0 indicates no fault condition).

All PowerLogic devices are equipped with RS-485 communications. This RS-485
standard allows up to 32 devices to be daisy-chained to a single communications
port. For example, up to 32 Circuit Monitors can be connected to the top RS-422
communications port of a PowerLogic Network Interface Module (PNIM). When
1 to 16 PowerLogic devices are connected to a single communications port, the
maximum length of the communications link, that is the distance from the
communications port to the last PowerLogic device on the chain, is 10,000 feet.
When more than 16 PowerLogic devices are connected to a single communications
port, the maximum length of the communications link changes in relation to the
baud rate. This is necessary to insure accurate communications at high rates of
speed (up to 19,200 baud). The table below shows the maximum distances
recommended at varying baud rates.
