Electric Fire Pump Controllers
3.2.2 Pushbuttons
Silence Alarm -
When an alarm condition exists,
the alarm buzzer will sound. If the Silence Alarm
button is pressed, the alarm buzzer will turn off. If a
subsequent alarm condition occurs after the silence
button is pressed, the buzzer will re-sound. Pressing
the Silence Alarm button again, will silence the
buzzer.
Motor Test -
Pressing the ‘Motor Test’ button will
simulate an automatic start on the controller due to a
low pressure condition.
If the Drain Valve menu item is enabled, the
controller will energize the drain valve and wait for
the panel to be started. If, after one minute, the
system does not detect a sufficient pressure drop to
start the controller, the drain valve will de-energize
and the panel will alarm. The LCD Display will
indicate Motor Test Failure.
If the drain valve is disabled, the system will
simulate a pressure drop and start immediately.
All automatic features of the controller such as Run
Period Timer and Automatic Shutdown will operate
as normal when the Motor Test button is pressed
and a low pressure condition is detected.
Data | Print -
The data, print button allows the user
to enter a multi-task menu where they can initiate
the download of the message history, system
diagnostics, system statistics, configuration file to an
external USB drive, upload custom messages, and
an additional language. If the optional printer (X1) is
included with the controller, the user will be able to
initiate a print cycle through this menu list.
Lamp Test -
The lamp test button allows the user to
test all of the LED's on the operator panel. Pressing
and holding this button will illuminate each LED on
the operator panel in successive steps.
Reset | Save/Exit -
The reset/save/exit button
serves two functions. Pressing the reset button will
reset any alarms that are present on the controller at
that time. If the alarm condition still exits it will alarm
again. When the user is in the programming mode,
pressing the save/exit button will save all of the user
adjusted values and make the recent changes
active.
-
The up arrow is used to navigate the main
display as well as the menu systems.
-
The down arrow is used to navigate the main
display as well as the menu systems.
| Ack. -
The enter and acknowledge button
serves two functions. When navigating the main
display, the enter button will allow the user to enter/
exit the message history, statistics, and diagnostics.
When in the menu system, the enter button will
allow the user to change the programmed set
points, and navigate to the next menu item.
Menu -
Pressing the menu will allow the user
access to the programming mode of the controller.
When in the programming mode, the menu button
will serve as a back button to return to the previous
menu heading.
3.3 Display Board Access Area
The display board is housed in a protective case that is
mounted on the inside of the controller door. Access to
communication ports and terminals is possible when the
controller door is open.
Note:
To allow for uniform identification, the frame of
reference when discussing the access area is with the
panel door open and the user facing the back of the LMR
Plus controller.
The USB port and I/O board power cable are located on
the bottom of the chassis. Optional RS232 and RS485
ports are available.
The display contrast adjustments can be made via the
open potentiometer dial in the back of the chassis.
3.4 Power I/O Board
The Power I/O board is used for all connections
pertaining to the operation of the controller. From the
remote inputs, starting conditions, and the alarm relay
outputs.
Refer to the schematic diagram mounted on the inside of
the controller door for all connection points specific to the
controller.
3.5 Main Isolating Switch/Circuit Interrupter
The main isolating switch (MIS) is intended for isolating
an electric circuit from its source of power. It has no
interrupting rating and must be externally operable.
The circuit interrupter (CB) is used to disconnect a
running pump motor, if necessary. The CB also provides
short circuit protection for the controller and the pump
motor and operates in conjunction with the Locked Rotor
Protector (LRP). In case of a short circuit the CB will trip
instantaneously. In the case of seizure of the pump or
motor while starting or running the LRP will trip the CB,
via a shunt trip, within twenty (20) seconds, as per NFPA
20 standards.
When necessary, a current limiter attachment may be
mounted on the bottom of the CB to increase the
interrupting capacity.
If one or more of the current limiter fuses blows, the
cause must be repaired immediately and new current
limiters installed when repairs are complete.
The isolating switch and circuit interrupter are
interlocked so that the enclosure door cannot be opened
with the handle in the On position, except by qualified
electrical personnel. This is accomplished by the use of
