Electric Fire Pump Controllers
Acceleration Timer (AT) -
The acceleration timer
can be programmed to allow the controller to run in
a reduced voltage state for a period of time. This
timer will start timing once a start signal has been
received and the startup relay has energized.
Weekly Test Timer -
A Weekly Timer can be
programmed that will automatically start and run the
fire pump motor. The Weekly Timer is set by
adjusting the day, hour, and minute of the desired
weekly run time, the length of time that this test shall
be performed, and a Test Interval (TI) (Range 1-52
Weeks) that will run the test every TI weeks. While
the weekly test timer is timing, the remaining time
will be displayed on the fourth line of the display.
Fail To Start Timer (FTS) -
The controller will verify
that the motor has reached an amperage rating
greater that 20% of the programmed motor full load
amps when the pump is running. If the amperage
has not reached 20% of the motor FLA after the Fail
To Start timer has timed out the Fail to Start alarm
will be generated.
Fail To Stop Timer -
The controller will verify that
the amperage draw from the motor has dropped
below 20% of the programmed motor full load amps
when there is a call to stop. If the amperage has not
dropped below 20% of the motor FLA, after the Fail
To Stop timer has timed out, the Fail to Stop alarm
will be generated.
Sequential Start Timer (SST) -
The SST can be set
to delay the starting of the pump when a low-
pressure 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 on the
fourth line of the display. The SST will not work on
Remote starts, Local starts and Emergency starts.
Alarm Set Points -
Following are the descriptions for
each menu item:
Phase Rotation -
The user will be able to change
the Phase Rotation that the program will base the
Phase Reversal alarm on.
Overvoltage (OV) -
An Overvoltage setting is built
into the controller. If the system voltage is above this
percentage setting, an alarm will be activated. There
is a one (1) second delay before alarming on
Overvoltage. Once the condition no longer exists,
the alarm will automatically clear.
Undervoltage (UV) -
An Undervoltage setting is
built into the controller. If the system voltage is
below this percentage setting, an alarm will be
activated. There is a one (1) second delay before
alarming on Undervoltage. Once the condition no
longer exists, the alarm will automatically clear.
Over Frequency (OF) -
An Over Frequency setting
is built into the controller. If the system frequency is
above this percentage setting, an alarm will be
activated. Once the condition no longer exists the
alarm will automatically clear. There is a three (3)
second delay before alarming on Over Frequency.
Under Frequency (UF) -
An Under Frequency
setting is built into the controller. If the system
frequency is below this percentage setting, an alarm
will be activated. Once the condition no longer exists
the alarm will automatically clear. There is a three
(3) second delay before alarming on Under
Frequency.
Custom Input/Output -
Refer to Appendix G. Following
are the descriptions or each menu item:
Custom Inputs -
The optional inputs have the ability to
be programmed for predetermined values or custom
values. The Custom Input Menu will display each input,
what it is programmed for and if there are any associated
optional relays and / or lights linked to the input. Refer to
Table 2 Generic Custom Input Labels for the generic
values the optional inputs can be programmed for. When
this input is received a message will be stored in memory
using the programmed label.
Table 2 Generic Custom Input Labels
Label -
If the input label is set to Custom Input, this
menu item will become active and allow the user to
enter the desired input name in. The label will be
limited to 20 characters in length and will include all
standard ASCII characters.
Energize Common Alarm -
If required, the
common alarm relay (3CR) can be programmed to
change states when this input is received. Default
value is Disabled.
Link to Relay -
All inputs can be linked to an output
relay. If the relay has been linked to another input or
is programmed for another alarm, the program will
show that the output is programmed for another
alarm and ask if the relay should be reassigned.
Default value is Disabled.
