For Model PC-100-LLC-CZ
and Controlgear.
A. Capabilities and Features
1. The equipment shall include:
a. A voltage range of 95-120VAC
For Model PC-200-LLC-CZ
a. A voltage range of 190-240VAC
2. The equipment shall have a probe input debounce time delay of 2 seconds.
3. The equipment shall include inputs for High and Low Probes with one common connection.
4. The equipment shall include an adjustment knob that allows the user to select Pump-Up operation or Pump-Down operation.
5. The equipment shall include an adjustment knob that allows the user to select the sensitivity of the probe inputs from 4.7k to
100k.
6. The equipment shall operate as follows when set for Pump-Up operation:
a. The relay shall energize when the resistance of the Low Probe is above the sensitivity threshold.
b. The relay shall de-energize when the resistances of the Low Probe and the High Probe are below the sensitivity threshold.
7. The equipment shall operate as follows when set for Pump-Down operation:
a. The relay shall energize when the resistances of the Low Probe and the High Probe are below the sensitivity threshold.
b. The relay shall de-energize when the resistance of the Low Probe is above the sensitivity threshold.
8. The equipment shall include one relay output pilot duty rated 480VA at 240VAC.
9. The equipment shall include one relay output general purpose rated 10A at 240VAC.
10. The equipment shall have one g reen indicator light. The light shall turn on when the relay is energized, and turn off when the
relay is de-energized.
11. The equipment shall allow single probe operation by shorting the High Probe input to the common connection, and using the
Low Probe input and common connection.
B. Electromagnetic Compatibility
