Control Panel Design
The ProVore®Duplex Control system (PDC-Series) monitors the
operation of two ProVore grinder pumps. The control system
comes in two parts: the controller with user interface and the float
switches mounted inside the basin. The P680 system includes two
ProVore pumps and two float switches.
The control panel monitors the liquid level in the basin and
alternates the two grinder pumps each cycle such that both
pumps receive equal wear. In the event one pump should fail, the
system automatically switches to the other pump.
LEDs and pushbuttons allow the operator to monitor and control
the system. Controllers require a dedicated circuit of proper
amperage. The PDC(W)-115 requires 115V/20A dedicated service,
while the PDC(W)-230 requires 230V/15A dedicated service.
The controller normally operates on primary power (115 VAC or
230 VAC), but if that power fails, an internal 9-volt battery allows
the controller to monitor liquid level and activate the alarm as
required.
On backup power (9-volt battery), the controller cannot run the
pumps. Pumps will only operate when primary power is supplied
to the control panel. The operator can test the alarm circuits,
change the horn status. Since pumps do not operate while the
controller is on backup power, the manual pump run feature will
not be functional.
Indoor PDC Models
The two float switches are connected such that only three cords
exit the cover. All three cords (two pump power cords and one
control cord) must be plugged into the controller box.
Outdoor PDCW Models
Outdoor models require power and control cord hardwiring. The
inner panel must be removed to provide access to the terminal
blocks inside the panel. The pump and switch plugs must be cut
off and wires stripped. Feed the cords, along with the incoming
power, through the liquid-tight strain relief bushings and wire into
the terminal block mounted in the PDC panel. A wiring schematic
is provided next to the terminal block. The panel has a secondary
terminal block for auxiliary contacts as required.
Primary Power
General Operation (115 VAC and 230 VAC)
The PDC panel controls the operation of two ProVore grinder
pumps in a pump-down application. Two floats are mounted to
the quick tree: a primary pump control float switch and an alarm
float switch. On the controller are indicators that show operating
conditions: High Water Alarm status, Pump Run status, Horn
status (indoor model), and incoming Power status. Operator
pushbutton controls are available to manually run the pumps, test
the alarm, enable or disable the horn (indoor model), as well as
reset the system. Both pumps are individually protected with a
manual resettable fuse to isolate a failed pump.
When the incoming water activates the primary pump float switch,
the controller will energize one of the pumps. Normally the water
level in the sump will recede as the pump operates and the pump
will turn OFF when the primary pump float switch drops to the
OFF position. Upon the next pumping cycle, the controller will
activate the next pump in sequence from the one that ran
previously, providing a pumping redundancy for the system. The
controller will continue to alternate pumps on each cycle.

Alarm Operation
In the event water fills the tank faster than it can be pumped out,
or if a pump fails to operate, the level can reach an alarm point by
activating the alarm float switch. If the alarm float remains closed
(up position) for 6 hours but the primary float switch is open
(down position), the High Water Alarm LED will flash and the
pump is turned off. This feature prevents the pump from running
indefinitely.
Active Alarm Condition
The following occurs when an alarm condition activates:
1. The pump that is (or should be) running is turned OFF and
the next pump in sequence is turned ON.
2. If the alarm float remains closed (float switch in up position)
for 4 sec., the High Water Alarm LED will illuminate steady.
3. The auxiliary relay will activate, closing its normally open
contacts and opening its normally closed contacts.
4. If the horn is enabled (i.e., Horn Disabled LED not flashing),
the horn will sound.
Post Alarm Condition
An alarm condition will remain active until the liquid level drops
below the pump float switch. When this occurs, the following will
take place:
1. The running pump will turn OFF.
2. The High Water Alarm LED will turn OFF.
3. The auxiliary relay will deactivate.
4. The horn (if ON) will turn OFF.
Pumping Alarm Condition
The controller monitors a “pumping alarm condition” where a
pump is called to run and the liquid level continues to rise and
goes above the alarm float switch. If a pumping alarm condition
occurs three or more of the last five times a pump is called to run,
the pump LED will flash indicating system components should be
checked. Any of the following conditions could cause a pumping
alarm condition:
1. A pump fails to operate.
2. The alarm float switch stays (mechanically stuck) in the closed
(ON or up) position.
3. There is a problem (blocked or leak) in the outflow plumbing.
4. The water inflow rate is greater than the pump out rate.
5. The primary float switch stays (mechanically stuck) in the
open (OFF or down) position.
A flashing LED indicates a component has failed and service is
required. To assist the service technician, the controller will
indicate which component has failed. Refer to Table 1.
Battery Backup Power
General Operation
On battery backup power, the controller is limited to alarm and
horn status indicators. The controller cannot run the pumps.
Pumps will only operate when primary power (115 VAC or
230 VAC) is supplied to the control panel.
The alarm float switch mounted in the tank monitors the liquid
level to indicate when an alarm level is reached. The pump float
switch is not used when the panel is on battery backup power
since pumps cannot operate.
Panel indicators show operating conditions of High Water Alarm
and Horn status. Operator pushbutton controls are available to
disable the alarm horn and reset the system.
When the liquid level drops below the alarm float, the float switch
will open, removing the alarm condition; likewise when the liquid
level rises above the alarm float, the float switch will close and an
alarm condition will be indicated.
Alarm Operation
As water fills the tank and the liquid level rises above the alarm
float, the float switch will be ON and an alarm condition is
activated. The following occurs when an alarm condition activates:
1. The High Water Alarm LED will flash.
2. The auxiliary relay will activate once for one minute, closing
its normally open contacts and opening its normally closed
contacts, then will deactivate.
3. If the horn is enabled (i.e., Horn Disabled LED not flashing),
the horn will sound.
