INSTALLATION & MAINTENANCE
MANUAL FOR LMR ELECTRIC
FOAM PUMP CONTROLLERS
15. FDF Foam Pump Controllers -
Programming Description
When the controller is programmed as a Foam Pump
Controller, it will work similar to the normal operation
with the following differences.
15.1 Stop
Mode
The Stop Mode will automatically be programmed for
Manual Stop and hidden from the menu system.
15.2 Run Period Timer
The Run Period Timer menu settings are hidden from the
menu system.
15.3 Pressure Transducer
The pressure transducer will be automatically disabled,
but not hidden from the menu system.
15.4 Programming Changes
If the controller has been programmed for Foam Operation
and is changed back to normal operation, all menu items
that were disabled will return to factory defaults AS PER
TABLE 1.
15.5 Low Foam Level
All correspondence to Low Suction has been modified to
read Low Foam Level. This includes alarm messages
stored in memory.
15.6 Low Foam Interlock
The Low Suction Shutdown function operated the same as
in a standard controller, however, it will be referred to as
Low Foam Interlock.
15.7 Deluge Valve & Pressure Start Inputs
The Deluge Valve (Input 36) and Pump Start (Input 39)
inputs, require a normally closed contact input that opens
when there is a call to start.
15.8 Future #1 Relay
The Future #1 relay is factory set for Interlock On. It is not
user programmable for any other functions.
15.9 Proof
Pressure
Switch
There is a Menu function called Proof Pressure Switch
within the menu system. It is selectable as either Enabled
or Disabled. When the Proof Pressure Switch is enabled
the controller will function as outlined below:
The Deluge Valve and/or Pump Start Inputs are received.
The Sequential Start Timer (SST) will start – the pump will
not start at this time.
After the SST has timed out, the controller will look at
the Future #1 (Proof Pressure Switch) input (Terminals
46 & 49).
If the Future #1 (Proof Pressure Switch) input has been
received, the pump will start. If a transducer is used for this
function, the controller will check to see if the pressure is
below the start point. If it is below the start point, the
controller will start.
If the Deluge Valve or Pump Start inputs are removed while
the SST is in operation, the SST will stop timing and reset
to zero.
The controller will not scan the Future #1 (Proof Pressure
Switch) input or pressure transducer until after the SST
has finished timing.
Local and Remote Start inputs will ignore the Proof
Pressure Switch and SST settings and will start the
controller immediately.
15.10 Interlock On
When selected to operate for a foam application, the
Interlock On function 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.
