Duplex Pump Controller Model FPC-1200 is a float switch
based duplex pump controller intended primarily for wastewater
lift stations and other pump down applications. It includes inputs
for the seal fail and temperature fail sensors on most submersible
pumps. It connects to four float switches to measure the tank level
and has relay outputs to control two pumps and a high alarm. It
has built-in HOA (hand-off-automatic) switches and pump run
lights. A lead pump selector switch permits either pump to be
selected as lead pump or alternation can be selected causing the
pumps to alternate as lead. The FPC-1200 uses removable terminal strips to make replacement in the field quick and easy. With the
addition of an enclosure, circuit breakers, and motor starters, the
FPC-1200 makes a complete low cost lift station controller.
OPERATION
The FPC-1200 uses four normally open floats as well as level sensing inputs so when the tank is empty all of the floats are open. On
rising water the Off float closes first which causes the controller to
take no action. The Lead float will close next as the water rises. The
controller will then turn on the lead pump. If this pump causes the
water level to fall the lead pump will be turned off when both the
Lead and Off float are out of the water and open. If the Lead pump
is not sufficient to control the water level then the Lag pump will be
started when the Lag float closes. The two pumps will not be
turned off until the Lag, Lead, and Off floats are out of the water
and open, at which time, all pumps will be turned off, The controller
has delays built into the software, which will insure that whenever
a pump is turned on, the second pump cannot come on for at least
8 seconds. Another delay insures that when a pump is turned off
the other one cannot turn off for 4 seconds. These delays help insure smooth pump operation and prevent excessive current
draws.

The last float input is for the High float. Whenever the High float is
under water (closed) then the high alarm condition is set. When a
high alarm condition is set the High Alarm indicator will flash on and
off, and the High Alarm light and horn outputs will be activated. The
horn can be silenced using an external mute button connected to
pin J2-9 to ground. Both the alarm light and horn will turn off when
the High float input opens. The FPC-1200 has an alarm test button
on the front panel which can be used to test the alarm horn and
light.
The pump controller has two inputs for pump seal fail (leak) sensors
(one for each pump). These inputs measure the resistance between
the input and ground. If the resistance is less than 50,000 ohms
then the seal fail indicator for that pump will be turned on. This action does not disable the pump; however it does demote the pump
to the lag position in the alternate order. In the event of a seal failure, the Seal Fail indicator and the Seal Fail output relay are energized, and the corresponding pump is demoted to lag position.
The pump controller has two inputs for pump temperature sensors.
If the controller detects a short between these inputs and ground
then a temperature failure condition does not exist. If the short to
ground is removed then a temperature failure condition exists and
the pump associated with that input will be disabled and the corresponding Temp Fail indicator illuminated. This condition will return
to normal when the short to ground is reestablished.

All of the float and sensor inputs are transient protected and filtered
to prevent electrical interference from causing improper operation.
The controller has two switches that select what mode the two
pumps are in.
These HOA switches have the following function:
H: When in HAND the pump will be constantly called to run.
O: When in OFF the pump will be off.
A: When in AUTOMATIC the pumps will be called by the pump
controller.
The Hand and Off functions of these switches will operate even if
the controller is off or has failed.
The controller has a switch that is used to select the lead pump.
When this switch is in the center position (ON) then the two pumps
will alternate as lead pump each pump cycle. When in the 1-2 position then pump one is the lead and when in the 2-1 position,
pump two is the lead.
The controller has two inputs, which should be connected to the
auxiliary switches on the two motor starters. These inputs, when
shorted, cause the pump running indicators to be illuminated.
Using these inputs may eliminate the need for panel-mounted
pump running lamps.
MAINTENANCE
The Model FPC-1200 Duplex Pump Controller is not field serviceable and should be returned if repair is needed (field repair should
not be attempted and may void warranty). Be sure to include a
brief description of the problem plus any relevant application
notes. Contact customer service to receive a return goods authorization number before shipping.
