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

 

Terminal #

 

Interlock On **

 

37

 

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.
