5.6.6 Hourly pressure recording
The controller can be set such that it will record a pressure
reading every hour on the hour.
5.6.7 Low suction shutdown
The controller can be programmed to shutdown when a low
suction condition is present. If this is desired, the user will
select Enabled. There will also be a shutdown delay timer
built-in (Range: 0-99 Seconds, Default: 0 seconds) along with
the selection of either a Manual or Automatic reset. If Manual
Reset is selected, the “Press to Reset All Conditions” in
the notification area must be activated to reset the alarm.
If Automatic Reset is selected (default reset mode), a delay
timer (Range: 0-99 Seconds, Default: 0 Seconds) must be
set. Once the input is closed, the controller will start the
Low Suction Delay timer. When the timer expires, if the input
for Low Suction is still closed, the controller will shutdown
the engine. When the input has cleared, the controller will
initiate the reset timer. After the reset timer has elapsed, the
controller will resume automatic operation. All timers will
be displayed in the notification area. Low Suction Shutdown
will have no affect on Local Starts, Remote Manual Starts, or
Emergency Starts.
ATTENTION
NFPA 20 SPECIFICALLY PROHIBITS THE INSTALLATION
OF ANY DEVICE IN THE SUCTION PIPING THAT WILL
RESTRICT STARTING OR STOPPING OF THE FIRE PUMP.

IS USED.
5.6.8 Low foam shutdown
The controller can be programmed to shutdown when a
low foam condition is present. If this is desired, the user
will select Enabled. There will also be a shutdown delay
timer built-in (Range: 0-99 Seconds, Default: 0 seconds)
along with the selection of either a Manual or Automatic
reset. If Manual Reset is selected, the “Press to Reset
All Conditions” in the notification area must be activated
to reset the alarm. If Automatic Reset is selected (default
reset mode), a delay timer (Range: 0-99 Seconds, Default:
0 Seconds) must be set. Once the input is closed, the
controller will start the Low Foam Delay timer. When the
timer expires, if the input for Low Foam is still closed, the
controller will shutdown the engine. When the input has
cleared, the controller will initiate the reset timer. After
the reset timer has elapsed, the controller will resume
automatic operation. All timers will be displayed in the
notification area. Low Foam Shutdown will have no affect on
Local Starts, Remote Manual Starts, or Emergency Starts.

5.6.9 Proof pressure switch
An external pressure switch can be activated on one of the
inputs. Enabling this feature requires that the programmed
input for Proof Pressure Switch is closed to allow the FPC
to start the engine.
5.6.10 Pressure units
The user can select which pressure unit of measure is to be
displayed. The units can be programmed for psi (pounds per
square inch), bar, or kPa (kilo Pascal).
5.6.11 Pressure transducer
Some applications do not require a pressure sensor to sense
the system pressure in order to start the engine when
required. In order to accomplish this, the pressure sensor
can be disabled through this menu item. Once disabled, the
pressure start point, pressure stop point will be removed
from the menu system. Refer to 4.3 for the Remote Auto
Start input to use instead of the pressure sensor.
5.6.12 Calibrate transducer
The controller allows for three (3) different forms
of calibration.
Full Calibration requires the system to be reduced to a
known value, typically 0 psi. This value is then entered into
the controller. The system pressure is then increased to a
higher known value which is also entered into the controller.
Calibrate Using Current Pressure is a partial calibration. The
low-pressure point is assumed to be correct. The high point
is adjusted based on the actual system pressure.
Reset to Factory Default resets the transducer calibration to
the original factory settings.
5.7 Timer values tab
Refer to Appendix F for the menu structure of the Timer
Values tab
5.7.1 Minimum run time (MRT)
The minimum run timer is used to automatically stop the
controller after a programmed time. The timer will start
timing once the pump has reached a running condition. If
Automatic Shutdown is disabled, the MRT will not be active.
It will not start on Remote Manual Starts or Local Manual
Starts. While it is timing the amount of time left on the
timer will be displayed in the notification area.
5.7.2 Sequential start time
The sequential start timer can be set to delay the starting
of the pump when an automatic starting condition exists. If,
during the timing of the sequential timer, the pressure rises
above the pressure start point, the timer will stop timing
and the starting sequence will discontinue. When the SST is
timing, the time left will be displayed in the notification area.
