•
Low Pressure Alarm -
A low pressure alarm point can be
selected that will be recorded in the controller’s history.
•
High Pressure Alarm -
A high pressure alarm point can be
selected that will be recorded in the controller’s history.
•
Auto Shutdown -
The stop mode is user selectable. If the
shutdown mode is programmed for Off, the engine must be
stopped via the local stop pushbutton, whether or not the
engine started via an automatic start. If the auto shutdown is
programmed for On, the controller will stop the engine
automatically after all starting causes have been returned to
normal and the run period timer has timed out.
•
Proof Pressure Switch -
An external pressure switch will
activate the Input #1 input as a starting input. This menu item
will only be active when the controller is programmed for a
Foam Pump Controller.
•
Low Suction Shutdown/Foam Level
- 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-
30 Seconds, Default: 10 Seconds) along with the selection of
either a Manual or Automatic reset.
If Manual Reset is selected, the Ack./Alarm button on the
keypad must be activated to reset the alarm.
If an Automatic Reset (default reset mode) is selected, a delay
timer (Range: 0-30 Seconds, Default: 10 Seconds) must be set.
The controller will continually verify if the input is still active.
Once the input has been removed, the timer will start timing.
Once the timer has finished timing, out the controller will return
to the automatic run mode.
When the shutdown delay timer is timing, the time left on the
timer will be displayed on the fourth line of the display. When
the controller is shutdown on Low Suction, the display will read
Low Suction Shutdown. The display will also show the
automatic reset time delay when timing. Low Suction
Shutdown will not work on Remote Starts.
ATTENTION
NFPA 20, SECTION 4.14.9.2(2), SPECIFICALLY PROHIBITS THE
INSTALLATION OF ANY DEVICE IN THE SUCTION PIPING THAT WILL
RESTRICT STARTING OR STOPPING OF THE FIRE PUMP UNLESS REQUIRED
BY THE AHJ. EATON CORPORATION ASSUMES NO LIABILITY WHEN THIS
FUNCTION IS USED.
•
Pressure Deviation -
A pressure setting may be selected, such
that any change in pressure greater than this setting, will
record the pressure fluctuation in the message history.
•
Hourly Pressure Recording
- The controller can be set so that it
will take a pressure reading every hour on the hour. If this
feature is not required it can be disabled by selecting
Disabled.
Timer Values -
Following are the descriptions for each menu
item:
•
Run Period Timer (RPT) -
The run period timer is used to
automatically stop the engine after a programmed time. It
can be programmed to operate based on either of two
separate conditions, the stop pressure point or when the
engine has started to run. If the RPT is programmed to start at
the Stop Pressure, the timer will start timing once the system
pressure has reached the programmed Stop Pressure Point.
If the RPT is programmed to start timing once the engine is
running, the timer will start timing once the controller has
received a running signal. If the Stop Mode is programmed
for Manual stop the RPT will not be active. It will not be active
on Remote Starts. While it is timing the amount of time left on
the timer will be displayed on the fourth line of the display.
•
RPT Start Mode -
The point at which the run period timer
starts timing is programmable. If it is programmed to start
timing after the engine has started, the RPT will start timing
once a signal has been received from the engine speed
switch. If it is programmed to start timing once the Stop
Pressure Point has been reached, the RPT will start timing
when the system pressure has risen above the programmed
Pressure Stop Point.
•
Weekly Test Timer -
A Weekly Timer can be programmed that
will automatically start and run the fire pump engine. 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.
•
AC Power Failure Alarm -
This setting is used to delay the AC
Power failure alarm. The time can be increased to prevent
nuisance alarms caused by short interruptions to the AC
power.
•
AC Power Failure Start -
If “Enabled”, the controller will
automatically start upon the loss of AC power. The start delay
is based on the AC Power Failure Alarm delay setting. Time
range is between 0 & 300 seconds. If “disabled” AC power
failure will have no affect on the starting of the engine.
In order to protect the engine, during the AC Power Failure
Start, an OVERSPEED condition, LOW OIL PRESSURE or HIGH
ENGINE TEMP alarm will automatically shutdown the engine.
•
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.
Custom Input/Output -
Refer to Appendix E. Following are the
descriptions for each menu item:
Custom Inputs -
The optional inputs have the ability to be
programmed with 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 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.
