Macromatic LCP Series Data Sheet
SINGLE PROBE | PUMP UP & PUMP DOWN
LCP Series
Operation
Pump Up (Fill): When the liquid level falls below the probe, a
fi xed time delay begins and the LED fl ashes Red. This time delay
prevents rapid cycling of the output relay and its load. At the end of
the time delay , the output relay energizes and the LED is Red ON.
The pump is ON to fi ll the tank. The relay remains energized until
the liquid level rises and touches the probe. The output relay deenergizes, turning off the pump, and remains de-energized and the
LED is Green ON until the liquid level falls below the probe.
Pump Down (Drain): When the liquid level rises and touches the
probe, a fi xed time delay begins and the LED fl ashes Red. This time
delay prevents rapid cycling of the output relay and its load. At the
end of the time delay , the output relay energizes and the LED is Red
ON. The pump is ON to drain the tank. The relay remains energized
until the liquid level falls below the probe level. The output relay deenergizes, turning off the pump, and remains de-energized and the
LED is Green ON until the liquid level rises and touches the probe.
Application Data
Voltage Tolerance:
AC Operation: +10/-15% of nominal at 50/60 Hz.
Load (Burden):
2 VA
Probe Voltage:
5V DC Pulsed
Resistance Sensitivity Range:
4.7K - 100K or 1K - 250K
Response Time:
Pick-up: Fixed in one second increments from 1-60 seconds
(Minimum Quantities may apply)

If the container is non-conductive or insulated, an additional
probe must be installed as the COM connection where it will
always be submerged.

DUAL PROBE | PUMP UP & PUMP DOWN
Operation
Pump Up (Fill): When the liquid level falls below the low
level probe, the output relay energizes and the LED is Red
ON. The pump is ON to fi ll the tank. The relay remains
energized until the liquid level rises and touches the high
level probe. The output relay de-energizes, turning off the
pump, and remains de-energized and the LED is Green
ON until the liquid level again falls below the low level
probe.
Pump Down (Drain): When the liquid level rises and
touches the high level probe, the output relay energizes
and the LED is Red ON. The pump is ON to drain the tank.
The relay remains energized until the liquid level falls
below the low level probe. The output relay de-energizes,
turning off the pump, and remains de-energized and the
LED is Green ON until the liquid level rises and touches
the high level probe.
