Sequence of Operation
Autotransformer Fire Pump Controllers
Introduction
Reference to Wiring Schematic, Publication
WS1800-50.
Note: Firetrol schematics are drawn showing the
equipment in a de-energized state.
Energizing The Controller
1. Close the Isolating switch/Circuit breaker by moving
the handle to the “ON” position.
Note: The unmarked, red, “Interlock” jumper wire, located
between terminals #1 & #10 on the Relay PC board,
(TB1), will prevent the MarkII unit from starting the electric
motor automatically. This jumper wire should only be
removed after the pressure settings have been input,
and the system pressurized at, or above the Stop set
point.
2. The factory programmed MarkII unit will begin
initialization. Upon completion, the display will confirm
the system pressure, the time, date, and “Interlock ON”,
which is an alarm condition and will cause the yellow
alarm LED to flash. Any other existing alarm conditions
(low system pressure, phase reversal, phase failure,
deluge open), will also be sequentially and continuously
displayed at this time, until each is rectified.
3. With the “interlock” jumper still in place, the electric
motor can only be started by depressing the START
push-button, located on the flange of the controller
enclosure, or by engaging the Emergency Run
Mechanism. After all alarm conditions have been
rectified, and the system pressurized at or above the
Stop pressure setting, then the “interlock” jumper may
be removed for the controller’s automatic operation
(“standby”). With the “interlock” jumper removed, a drop
in system pressure to the MarkII’s set start point, will
start the electric motor.
4. The deluge valve contacts are only operational if the
factory jumper has been removed and a normally closed
deluge valve contact has been placed between terminals
1 and 8 of the Relay PC board, (TB1). The Remote Start
is only operational if a normally open, momentarily closed
contact is wired to terminals 6 and 7 of the Relay PC
board, (TB1). If engaged, the Emergency Run Mechanism
will cause the pump motor to run as described in the
Emergency Starting and Stopping section.
Automatic Start and Stop
1). The controller pressure transducer initiates the
automatic start circuits for the pump motor. When
pressure falls at or below the MarkII Start setting, relay
1CR is energized. 1CR normally open contact, closes
•
FTA1800
to the coils of 1S & 2S starters, allowing voltage to the
motor windings. (see section Pump Motor Starting
Sequence for more information). An autotransformer is
connected to minimizing line disturbances during starting.
At the same time the MarkII initiates the internal
transition time, factory set for 2 seconds. Once this
expires, 6CR is energized. 6CR normally open contact
closes to the coil of 1M starter, 1S coil is de-energized
and mechanically locked out (motor circuit remains
closed during transition), allowing the motor to be directly
connected to the power source.
Note: Allow the motor to either run for 5 minutes, or
allow 5 minutes between starts, for initial start component
cool down period.
The minimum run time is a part of the MarkII Menu,
“Timer Settings”. The minimum run time factory setting
is 10 minutes. In this mode, minimum run time begins
when the pressure falls at or below the “Start” set point,
calling for the pump motor to run. When pressure drops,
this signals the MarkII to output via the Relay PC board,
directly to the 1CR relay coil. The relays normally open
contact closes, allowing line voltage to the coils of 1S &
2S contactors. The contactors’s 3 normally open
contacts close, allowing voltage through the
autotransformer, to the motor. After a 2 second delay,
6CR relay coil is energized. 6CR normally open contact
closes, allowing line voltage to the coil of 1M contactor,
and de-energizing 1S contactor (motor circuit remains
closed during transition). The 1M’s 3 normally open
contacts close, allowing direct line voltage to the motor,
and the motor now runs at full speed. Simultaneously,
the minimum run function of the MarkII is activated,
maintaining voltage on the 1CR relay, keeping the motor
running until the 10 minutes expire. At this time, with
pressure restored at or above the Stop set point, 1CR
and 6CR coils will de-energize, re-opening the normally
open contacts, de-energizing the 1M and 2S coils,
causing the motor to stop.
If pressure is restored at or above the Stop set point
of the MarkII, and even if the minimum run time has not
yet expired, the manual STOP push button, located on
the flange of the controller can be depressed to manually
stop the engine. This also resets the minimum run time
function of the MarkII.
Manual Start and Stop
The pump motor may be manually started by using
either the START push-button mounted on the flange of
the enclosure or by using a normally open, momentarily
closed, remote start push-button connected to terminals
6 and 7.
When the START push-button is depressed, or a
remote start signal is seen through terminals 6 & 7, the
MarkII will output through the relay pc board to 1CR relay
coil and the sequence of events described in section
“Automatic Start & Stop” will begin. The MarkII minimum
run time feature will not be activated.
The pump motor will continue to run until the STOP
push-button is depressed. When the STOP push-button
is depressed, 1CR relay coil is de-energized, interrupting
the voltage to 1M & 2S coils, which causes the motor to
stop.
Deluge Valve Operation
To operate the controller utilizing a deluge valve, the
wire jumper between terminals 1 and 8 must be removed
and a normally closed, open to run deluge valve contact
wired in its place.
When the deluge valve contact opens, relay 1CR
coil is energized, and the sequence of events described
in section “Automatic Start & Stop” will begin. The MarkII
minimum run time feature is also activated.
When the deluge valve contact closes, and minimum
run time expires, relays 1CR & 6CR are de-energized,
interrupting the voltage to 1M & 2S coils, which causes
the motor to stop.
Shutdown Interlock Operation
The shutdown interlock, if used, is a normally open,
closed to interlock contact wired to terminals 1 and 10.
When the interlock contact is closed, relay 1CR
cannot be energized by inputs to the MarkII from the
pressure transducer, or the deluge valve. The controller
may be started manually by depressing the START push
button. See the specific starting operation for more
details.
out 1S (motor circuits remain closed during transition).
The motor is automatically connected directly to the
power source, applying full voltage to the motor.
Emergency Starting and Stopping
The controller is equipped with an emergency run
mechanism for use in the event of a coil burnout or other
electrical problem which would prevent normal starting
of the pump motor. The mechanism attempts to both
electrically and mechanically start the pump motor.
When the emergency run mechanism is utilized,
the 1M coil is energized, closing the contacts leading to
the motor windings. This, in effect, attempts to
electrically start the pump motor.
The emergency run mechanism also manually
closes the 1M contactor, starting the motor at full voltage.
This will run the motor as long as the main three phase
power is available.
If the pump motor is running via the emergency run
mechanism, DO NOT release the mechanism to stop
the motor. Place the isolating switch/circuit breaker
handle in the off position, then release the emergency
run mechanism. Releasing the mechanism while the
motor is running could result in damage to the motor or
the motor contactors.
Note: The emergency run mechanism is not intended
for, nor should it be used as a testing device. Its sole
purpose is to attempt to start the pump motor in the
event of a failure.
Pump Motor Starting Sequence
Whenever relay 1CR, and sequentially, after transition
time expires, 6CR coils are energized, line voltage is
allowed to the coils of the motor starting contactors.
During Autotransformer starting, the following sequence
occurs.
1). 1CR contact closes, energizing contactors 1S & 2S.
1S & 2S connect the motor to the power source, through
the autotransformer. The autotransformer is used to
supply reduced voltage when starting the motor. The
autotransformer has three taps for selection of starting
current and torque: 50% tap for 150% current and 25%
torque, 65% tap for 250% current and 42% torque and
the 80% tap for 384% current and 64% torque.
2). When the MarkII transition time expires (factory set
at 2 seconds), 6CR relay is energized, allowing contactor
1M to energize, de-energizing and mechanically locking
