3.2.3 Motor
Rotation
Check: With the controller energized,
operate the ‘START’ pushbutton immediately
followed by the stop button to check the direction of
the pump rotation. If rotation is incorrect disconnect
power and reverse connection of the load terminals
of the motor contactor T1, T2, T3.
3.2.4 Pressure Set Points: Adjust the pressure set points as
detailed in Section 6; Pressure Start / Stop Points.
(Also operable if user selected on Foam Pump
controllers – see Section 15 of this manual.)
3.2.5 Starting and Stopping: With the controller isolated
and the START PRESSURE and STOP PRESSURE
values programmed, energize the controller. If the
system water pressure is lower than the START
PRESSURE, the pump will start. If the controller is
set up for fully automatic operation, the pump will
stop when the pressure is above the stop point and the
Running Period Timer (RPT) has completed its timed
interval. If the controller is set up for semi-automatic
operation (programmed for Manual Stop mode), the
‘STOP’ pushbutton must be operated to stop the
pump. Note that the system pressure must be equal to
or greater than the programmed STOP PRESSURE
value, otherwise the pump will stop only when the
pushbutton is pushed. (Also operable if user selected
on Foam Pump controllers – see Section 15 of
this manual.)
If the pump does not start when the controller is
energized, or after it has been stopped as described
above, operate the START pushbutton and check that
the pump starts. Operate the STOP pushbutton and
check that the pump stops. The RPT has no effect
in this case.
3.2.6 Circuit
Breaker
Setting: Factory set. Do not adjust.
3.2.7 Run
Period
Timer: The RPT must be set for a
minimum of 10 minutes. Refer to Section 6 for
programming of the RPT.
(Not available on Foam
Pump Controllers – see section 15.2 of this manual).
3.2.8 Sequential Start Timer: The SST is programmable,
refer to Section 6. If not required set the SST to zero.
If required, the lead pump SST should be set to zero
seconds and the lag SST to 5-10 seconds. If there are
more than two pumps in the system, allow a 10
second delay between pumps.
3.2.9 Accelerating
Timer: Used for reduced voltage
controllers only. The AT has a nominal setting of
5 seconds. If it is found that more time is required
to allow the pump to come up to speed, the timer
may be adjusted to suit. Refer to Section 6 for
programming of the AT. Note: The acceleration
timer cannot exceed 10 seconds.
3.2.10 Undervoltage / Overvoltage Setting: If the Under-
voltage/Overvoltage alarms are present, check the
programmed values by referring to Section 6 or
refer to the STATUS printout. If the values are
programmed to their maximum and the alarms
continue to occur, please check your main voltage
supply to ensure that the power available is
dependable as per NFPA, Pamphlet 20 standards.
3.2.11 System Voltage: The actual voltage can be viewed
on the LCD display using the STEP pushbutton on
the enclosure flange. Refer to Section 4.3.
3.2.12 Phase Current(s): Amperes, on all three phases,
can be viewed on the LCD display using the STEP
pushbutton on the enclosure flange. Refer to
Section 4.3.
3.3
Field Failure Alarm Simulation
Ensure that there is power to the controller and that the MIS
and CB are in the ON position. Placing a jumper between
terminal 49 and the terminals listed below, found on TB1,
will test the respective alarms/conditions. Their respective
LED will turn ON and the Common Alarm Relay, 3CR,
will de-energize. Pressing the RESET key on the membrane
faceplate resets the alarms.
Note:
The starting conditions will start the pump and
CAUTION must be taken to ensure safety.

Foam Pump controllers require a N/C input. All controllers
are supplied with jumpers between terminals (36, 49) and
(39, 49). Jumpers must be removed for a foam pump
controller in order to enable the simulation.
Interlock Condition

Interlock On **

Remote Start and Local Start will ignore the interlock when
unit is programmed as a foam pump controller.
*
Caution: Motor contactor will energize and pump
will start.
** After placing a jumper between terminals 37 & 49,
test the interlock by pushing the START pushbutton
located on the enclosure flange. With this jumper in
place the pump will NOT start. If currently running,
the pump will stop when a jumper is placed between
terminals 37 & 49.
For Foam Pump controllers, the interlock condition
will not lock out the pump and prevent it from running,
when either a Remote Start or Local Start input has
been received. If the pump is running based on Remote
Start or Local Start, the Interlock will not shut the
pump down.
