FTElectric Manual v2.8.9.x (CDL)
Variable speed electric fire pump controllers (FTA31xx) are designed to start an electric motor driven fire pump.
The FTA31xx is equipped with a Variable Frequency Drive (VFD) that will regulate the motor speed by controlling
the frequency outputted to the motor in order to reach a certain pressure (Setpoint pressure). It can either start the
fire pump manually through the local start pushbutton or automatically through the sensing of a pressure drop in
the sprinkler system. The fire pump controller is supplied with a pressure transducer. The fire pump can be
stopped manually with the local stop pushbutton or automatically after the expiration of a field programmable
timer. In both cases, stopping is only allowed if all starting causes have disappeared.

Variable Speed Electric Fire Pump Controllers Mode Switch
The FTA31xx is equipped with a VFD Mode Switch that is located under the MarkIII+. It is protected by a
lockable cover, and has 2 positions, VFD and BYPASS. In normal usage the VFD Mode Switch should remain in
the VFD mode position.
VFD: The controller will start the motor using the VFD starting mean.
BYPASS: The controller will start the motor using the bypass starting mean.
Starting mean
VFD STARTING MEAN
The variable speed electric fire pump controller is equipped with a Variable Frequency Drive (VFD) which is the
primary starting mean. Upon reception of a starting demand, the motor will be started using the VFD. The VFD will
adjust the speed of the motor by varying the frequency outputted to the motor to maintain the system pressure at a
desired set pressure (Setpoint Pressure).
BYPASS STARTING MEAN
A secondary starting mean will take over the motor if the VFD comes to fail or if the VFD mode switch is placed in
the Bypass mode position.
MANUAL VFD BYPASS
If the mode switch change position while the motor is running, the motor will stop and restart in the new
mode.
AUTOMATIC VFD BYPASS
When running in VFD mode, the controller will automatically bypass the VFD following the activation of
one of the 3 VFD alarm: VFD FAULT, VFD UNDERPRESSURE or VFD NOT READY. Once the VFD has
perform an Automatic VFD Bypass, it will stay in that state until the alarms are manually reset.
Introduction

FULL VOLTAGE STARTER
MODEL FTA3100S: ACROSS-THE-LINE STARTER
This model will apply full voltage to the motor when the bypass starting mean is activated.
REDUCED VOLTAGE STARTERS
MODEL FTA3130S: SOLID STATE STARTER
This model does not require a multi-connection motor. It only requires 3 conductors between the
controllerand the motor.
Upon activation of the bypass starting mean, a solid-state starter is utilized to supply a step less ramp-up
voltage to the motor until the motor reaches its full speed. At that time, a fully horsepower rated by-pass
contactor is energized, connecting the motor directly to full voltage and eliminating all heat loss within the
solid-state starter. This controller also features a soft motor stopping mode and a hard stop mode. For a
hard stop, hold the stop pushbutton until the motor stop.
Methods of Starting/Stopping
The controllers are available as combination automatic / non-automatic with provision for manual or automatic
shutdown (an automatic shutdown is only possible after an automatic start).
METHODS OF STARTING
AUTOMATIC START
The controller will start automatically on low pressure detection by the pressure sensor when the pressure drops
below the cut-in threshold.
MANUAL START
The motor can be started by pressing the START push button, regardless of the system pressure.
REMOTE MANUAL START
The motor can be started from a remote location by momentarily closing a contact of a manual push button.
REMOTE AUTOMATIC START, DELUGE VALVE START
The motor can be started from a remote location by momentarily opening a contact connected to an automatic
device.
EMERGENCY START
The motor can be started manually by using the emergency handle. This handle can be maintained in a closed
position. The manual “EMERGENCY RUN” device will always initiate across-the-line starting.
Important: to avoid damaging the contactor, it is recommended to start the motor in this manner:
1) Shutdown the main power by using the main disconnect means,
2) Pull the emergency handle and lock it in closed position,
3) Turn the power back on by using the main disconnect means.
WEEKLY START
The engine can be started (and stopped) automatically at the preprogrammed time.
TEST START
The motor can be started manually by pressing the run test button.
*In VFD mode, if a start requests not based on the system pressure is triggered and the pressure remains above
the Setpoint pressure, the motor will run at the minimum speed (VFD parameter).
METHODS OF STOPPING
MANUAL STOP
Manual stop is done by pressing the priority STOP push button. Note that pressing the stop push button will
prevent the motor from restarting as long as the button is pressed, plus a two second delay.

4
AUTOMATIC STOP
Automatic stop is possible only after an automatic start and this function has been activated. When this function is
enabled, the motor is automatically stopped 10 minutes after the restoration of the pressure (above the cut-out
threshold) given that no other run cause is present.
EMERGENCY STOP
The emergency stop is always possible in any starting condition and is done by using the main disconnecting
means located on the door.
Transfer switch operation Sequence
TRANSFER TO ALTERNATE POWER SOURCE
The Transfer to Alternate Power Source starts automatically when at least one of the following conditions are
present:
- Normal Power voltage falls below 85% of nominal voltage,
- Normal Power Phase Reversal is detected,
- Transfer Switch Test push button is pressed.
When an under voltage condition on any phase of the Normal Power source is detected by the sensor, a 3 second
normal power source outage delay timer starts timing.
If the normal source voltage rises above the sensor dropout setting before the 3 second time delay expires, the
transfer sequence is cancelled.
If the Normal Power source voltage is still below the sensor dropout setting (85%) when the time delay expires, a
relay is deactivated sending a signal to start the generator set. At the same time, a voltage and frequency sensor
begins monitoring the Alternate Power Source. The sensor will accept the alternate power source only when both
voltage and frequency reach a pre-set pickup value. An approximate 15 second time span occurs because the
engine-driven generator cranks, starts and runs up to nominal pickup value.
When the Alternate Power Source is within acceptable limits (above 90% of the nominal voltage) for a certain set
time (factory set at 3 seconds), the transfer to alternate power source is initiated.
The transfer switch will remain in the alternate power source position until the normal source is restored.
RETRANSFER TO NORMAL
Important: The transfer switch will stay in alternate position, if the motor is running, for as long as the alternate
power source is within acceptable limits. The retransfer sequence is enabled if the motor is not running.
The Retransfer to the Normal Power source starts when the voltage sensor detects restoration of the Normal
Power Source within acceptable limits. The voltage level must rise above the pre-set pickup value (90%) on all
phases before the sensor will accept the normal source.
When the normal source is accepted by the sensor, the retransfer to normal delay timer starts timing (factory set at
5 minutes). This delay can be by-passed by pressing on the count-down timer displayed on the screen (if a flashing
“X” is displayed).
This delay prevents immediate load retransfer to the normal source. The delay insures that the normal power
source has stabilized before reconnection of the Fire Pump Motor. If the normal source voltage falls below the pre-
set dropout value before the time delay expires, the timing cycle is reset to zero. If the alternate power source fails
during the timing cycle, the load is immediately retransferred to the normal source, if that source is acceptable.
The Automatic Transfer Switch is now feeding the Fire Pump Motor from the Normal Power Source again.
Upon retransfer to the normal source, the 5 minute cooling timer starts counting down, keeping the engine running
during this cool-down period. This delay can be by-passed by pressing on the count-down timer displayed on the
screen (if a flashing “X” is displayed).
After the time delay, the relay is re-activated to shut down the engine-driven generator. All circuits are reset for any
future normal source failure.
Every time the transfer switch needs to change from one power source to the other, a running motor is stopped
during the transfer to prevent instant across the line starting of an already turning motor. If the motor still needs to

5
run when the transfer sequence has completed (plus a factory set 2 second timer), the motor will be restarted
following its default start-up sequence.
Manual Operation of the Transfer Switch
There is 180° between the Normal position (I) and the Alternate position (II). To operate manualy the Transfer
Switch:
1 - Use the Disconnect Switches to turn OFF the power of both Normal and Alternate sides.
2 - Open the door of the Alternate side.
3 - On the Transfer Switch, put the selector switch in Manual mode.
4 - Take the handle, situated inside the controller door and insert it in the square hole on the Transfer Switch.
5 - Turn the handle clockwise 180° to transfer from Alternate to Normal position.
Turn the handle counterclockwise 180° to transfer from Normal to Alternate position.
6 - Remove the handle and put it back on the support inside the controller door.
7 - On the Transfer Switch, put the selector switch in Automatic mode.
8 - Close the door and using the disconnecting switch handles put back the power on both sides.
BE CAREFUL:
- Do not close the controller door if the handle is still installed in the Transfer Switch.
- Do not operate manualy the Transfer Switch if the Normal side power is still ON.
- Do not forget to replace the Transfer Switch in Automatic mode.
