®
Model PC-XXX-LLC-CZ liquid level controllers are used to detect the
presence of conductive liquids and control the operation of a single pump. The line voltage must be
specified in the part number.
These devices use two probe inputs (a High Probe and a Low Probe, with a tank or probe common)
to determine whether to start or stop a pump. The inputs to the PumpSaver
®
are usually liquid level
sensors that sense a decrease in resistance between the probes when liquid contacts the sensors.
Pump-up or pump-down operation may be selected by turning the adjustment knob to the left or
right side of center on the sensitivity range. See Figure 3. The probe sensitivity may be selected by
turning the adjustment knob to the desired resistance threshold. This sets the level at which the
PumpSaver
®
determines whether liquid is present at the probes. If the resistance of the probe drops
below the threshold, then liquid is detected. If the resistance of the probe rises above the threshold,
then liquid is not detected.
These devices may also be used in a single-probe application (with a tank or probe common).
CONNECTIONS for PC-XXX-LLC-CZ Products
1. The PC-XXX-LLC-CZ requires an 8-pin socket, part number OT08-PC (sold separately).
2. Mount the PumpSaver
If the location is wet or dusty, it should be mounted in a NEMA 4 or 12 enclosure.
3. For pump motor control, connect the normally open contact, socket terminal 3, and
common, socket terminal 1, in series with the motor’s magnetic contactor coil (M) as shown
in Figure 2.
4. Connect the power supply L1 to socket terminal 2 and power supply L2 to socket terminal
7.
5. Connect high level probe to socket terminal 6.
6. Connect low level probe to socket terminal 8.
7. If the tank is conductive, connect a probe common wire between the tank and socket
terminal 5. If the tank is not conductive, a wire must be connected between a reference, or
common, probe and socket terminal 5.
8. Plug the PumpSaver
Note: The PC-XXX-LLC-CZ uses a 5vdc pulse to check the resistance of each probe, so the
probes must be isolated from other voltage sources.

socket in a convenient location in or near the pump control panel.

®
into the socket.
1
For single probe applications, connect a wire between socket terminals 6 and 5. Connect the single
probe between socket terminals 8 and 5. The single probe must be connected to the low probe and
the high probe input must be connected directly to common.

SETTINGS
Figure 3: Selectivity and Mode Selection
Use the adjustment knob shown in Figure 3 to set the mode of operation and the sensitivity threshold
for the probes. Set the sensitivity from 4.7k to 100k on the left half of the dial for pump-down
applications. Set the sensitivity from 4.7k to 100k on the right half of the dial for pump-up
applications

OPERATION
Apply power to the system. The green run light will come on if the relay has been energized.
The PumpSaver
®
is equipped with a debounce time delay. The PumpSaver® will wait for the time
delay to complete before energizing/de-energizing the relay.
Pump-Up
3
The relay is energized when liquid is not detected at the low probe, regardless of the state of the
high probe. When the liquid level rises and liquid is detected at the low and high probes, the relay is
de-energized.
4
Pump-Down
The relay is energized when the liquid level rises and is detected at the low and high probes. When
the liquid level drops and no liquid is detected at the low probe, the relay is de-energized, regardless
of the state of the high probe.
2
Reducing the resistance setting will provide increased sensitivity to the presence of liquid.
3
When used with a single probe in a pump-up setting, the relay will energize the pump when no liquid
is detected by the probe and de-energize when liquid is detected by the probe.
4
When used with a single probe in pump-down setting, the relay will energize the pump when liquid is
detected by the probe and de-energize when liquid is not detected by the probe.

SYMPTOM

LIGHT
PATTERN
N/A
SOLUTION
Verify that the product is wired properly. If
wiring is correct, then measure the line voltage
at terminals 2 and 7 on the octal base. If the
voltage is below the minimum listed in the
Specification Table for the model in use, the
PumpSaver
operate its internal electronics. Also check for
a valid input to the unit from the appropriate
probe. If the voltages and probe inputs are
correct but unit fails to function, call SymCom
at (800) 843-8848 or (605) 348-5580.
