Bug Fixes:
The MM2 firmware has been updated to correct
problems found in the field relating to the
communication cctry. , start inhibit, and G/F
Trip/Alarm Elements.
COMMUNICATIONS:
1.) When the parity setting in communications was
set to even parity, the MM2 would not respond
to odd bit count slave addresses (i.e. 1,2,4,7).
As well, when the parity setting was odd the
MM2 would not respond to even bit count slave
addresses (i.e. 3,5,6,9).
Since fixed in ver. 4.01.
4.01
START IHIBIT:
2.) When a start inhibit was issued (i.e. Starts per
Hour or Backspin Timer) the inhibit lockout
could not be reset by setting the active inhibit to
Off.
Since fixed in ver 4.01.
G/F DETECTION:
3.) When large CT primary values were used with
high Ground Trip/Alarm levels (i.e. 60% of CT),
the MM2 would trip on G/F much sooner than
expected.

CHANGES/ENHANCEMENTS
Resetting of Alarms: The MMII will now allow the
Acceleration Alarm, Open Control Circuit Alarm,
Motor Greasing, Contactor Inspection and Motor
Stopped Time Alarms to be reset using the
Faceplate Reset Key. All other alarms will reset
when the Alarm condition clears.
OPEN CONTROL CIRCUIT TRIP: In Two Wire
control applications, where a constant start signal is
provided the MMII should be configured to trip on
an open control circuit. An Open Control Circuit
occurs when feedback on Contactor Status
(terminal 55) stays open when a start operation is
executed. This condition may occur if a control
wiring problem develops or because of an AUX
contact failure.
GROUND FAULT TRIP DELAY: This setpoint has
been expanded to 10s from 2s.
MOTOR AVAILABLE AUTO: This Aux Relay
function will activate the Aux Relay when the motor
is available to start in Auto Mode.
MOTOR AVAILABLE : This Aux Relay function will
activate the Aux Relay when the motor is available
to start regardless of which mode the MMII is
presently in (Auto or Manual). The AUX Relay will
remain active when the motor is running to indicate
normal operation. (i.e. no stop inputs or trips)

Ground Fault trips. When a trip occurs that is not
in the list above, and power is removed, the MMII
will display zero for the pretrip values.

USER DEFINABLE MEMORY MAP DEFAULT
VALUES: For convenience default User map
values have been added. The User Definable
Memory Map is still fully customizable however.
The defaults are separated into three sections.
Regular Polling data items, data that is read when
a Trip, Stop or Alarm occurs and data that can be
monitored as time permits.
CHANGES/ENHANCEMENTS
Duty/Standby: The Duty/Standby starter type
allows a single MMII to control two identical motors.
MOTOR SELECTOR A/B: This setting is used in
conjunction with the Duty/Standby starter type. In
the Manual mode the state of this interlock
determines which of the two motors is used for
starting. When A is selected only the contactor A
output relay will respond to start commands. When
B is selected only the contactor B output relay will
respond to start commands.
DUTY SELECT MAN/AUTO: This setting is used
in conjunction with the Duty/Standby starter type.
This input determines the mode of operation for the
Duty/Standby starter type either Manual or Auto. In
the Auto mode the MMII will alternatively start
Motor A and Motor B. When the number of starts is
an even number Motor A will be started the next
time a start command is issued. When the number
of starts is odd Motor B will be started the next
time a start command is issued. In the event of a
trip on either motor, the motor that tripped will be
prevented from starting until reset is pressed. All
starts will default to the untripped motor. When the
trip occurs the MMII automatically resets the trip to
allow the other motor to be started. The trip
message becomes an alarm message, which must

be reset to allow the tripped motor to start. If the
second motor trips the MMII will remain tripped until
reset is pressed. The details of the Manual mode
are described above under MOTOR SELECTOR
A/B. Note: Faceplate Stop, Process Stop and
ESD Stop trips MUST be manually reset
regardless of the Duty/Standby mode. Local
Isolator and Plant Interlock trips reset only
when the input is healthy.
SEGREGATED G/F ALARM: This function will
energize the AUX Relay when a ground fault alarm
occurs when configured. If the other AUX Relay is
configured for ALARMS it will not operate until
another alarm occurs that is not a ground fault
alarm.
PRE CONTACTOR B: The AUX Relay will
energize when the MMII receives a start B
command. The Contactor B relay will start the
motor after the delay specified in the Aux Relay
Pre Start Delay setpoint. The Aux Relay will deenergize after the AUX Relay Post Start Delay
times out or when Contactor B de-energizes. Pre
Contactor B is active for TWO SPEED, FV
REVERSING and DUTY/STANDBY starter types
only.
THERMAL CAPACITY ALARM: When the thermal
capacity increases to the value set by this setpoint
an alarm will occur. This alarm can be assigned to
a specific aux relay.
Bug Fixes:
During testing it was noticed that the external start
message was not being cleared for all starter types
except autotransformer. The number of starts
recorded would miss the occasional start when the
switches changed state while in the control task.

2.) PROCESS STOP:
When set to 'LATCHED', a momentary
opening of a contact connected to terminal 51
will cause a latched trip condition. Pressing
the reset key will clear the trip allowing the
operator to restart the motor. NOTE: If the
MMII is receiving a constant start signal, the
motor will start as soon as reset is pressed.
3.) PROCESS INTERLOCK E-J:
Process interlocks E-J function exactly like
Process interlocks A-D.
4.) REMOTE RESET:
This function replaces the faceplate reset key.
When configured the faceplate reset key will
not reset any trips. When other switch inputs
are used to reset specific trips, the remote
reset switch input will not reset those trips. i.e.
Undercurrent Trip, Emergency Stop Trip,
Lockout Trips.
5.) STOP A:
This function is used for end of travel
applications. When a programmable input
configured for STOP A opens, the Contactor
A output relay will open. When the STOP A
input is open, the motor cannot be started
using start A commands or switch inputs.

Bug Fixes:
1.) The aux1 relay inhibit feature would inhibit the
aux2 relay timers but the relay would not be
affected when aux2 was configured for precontactor a delay.
2.) A setpoint was added to factory service which
will allow changing the welded contactor and
open control circuit alarm times. This really
isn’t bug, but it can help in situations were the
customer is using an interposing relay in the
control circuit and feedback to the MMII takes
longer than 1 second. Caution should be used
when setting this timer to long times. It is
meant for minor adjustments, but has the
capability to go as high as 10 minutes.

NEW AUTOTRANSFOMER STARTER TYPES:
There are now individual starter types for open and
closed transition autotransformer starters. A
setpoint to change the order that the main and wye
contactors close during a start has been added to
support different wiring practices.
MEMORY MAP UPDATES:
1.) The parity setpoint has been added to the
Memory Map.
2.) The MMII contains a User Definable area in
The memory map.
This area allows re-mapping of the
addresses of any Actual Values or Setpoints
registers. The User Definable area has two
sections:
A Register Index area (memory map
addresses 1280H-12F7H) that contains 120
Actual Values or Setpoints register addresses.
A Register area (memory map addresses
0100H-0177H) that contains the data at the
addresses in the Register Index.
Register data that is separated in the rest of
The memory map may be re-mapped to
adjacent register addresses in the User
Definable Registers area. This is
accomplished by writing to register addresses
in the User Definable Register Index area.
This allows for improved throughput of data
and can eliminate the need for multiple read
command sequences.
3.) The response time of the MMII has been
decreased for high speed communication
applications.

MOD # SUPPORT:
1.) all provisions to support multiple MOD s on the
MMII was removed as per Norris W. Any
future Combination of MODs will require a new
mod Number
2.) added MOD607 which combines MOD602 &
MOD608.
INTERLOCK INPUTS:
1.) Ten new setpoints were created, one for each
programmable input, called “IL1 SWITCH
TYPE:” through “IL10 SWITCH TYPE:”. These
new setpoints allow each individual
programmable switch input to be configured for
normally open operation (N.O.) or normally
closed operation (N.C.).
This allows for proper operation of the
Switch input function regardless of the type of
External switch being used for the input.
When set to N.O. (factory default), if the
Switch input is closed, it is in the ‘healthy’
Position; if the switch is open, it is in the
‘unhealthy’ position. When set to N.C., if the
switch input is open, it is in the ‘healthy’
position; if it is closed, it is in the ‘unhealthy’
position.
These 10 setpoints are located in the MMII
Memory map at locations 11C0 to 11C9.

TWO SPEED MOTOR STARTER TYPE:
Added a setpoint to be used in conjunction with the
TWO SPEED STARTER called HIGH SPEED
START BLOCK. When enabled, this will force
MMII to start the motor in low speed before
switching to high speed. Starting directly to high
speed will be blocked.
LOCKOUT RESET:
Modified code such that when the 'LOCKOUT
RESET' function is configured and active, it
overrides the RESET button on the MMII faceplate,
even if the "LOCKOUT RESET USING RESET
