LIQUID LEVEL CONTROL

LLC8 Series Information

  • Designed for Low Level Cutoff Protection
  • Energized on Wet Probe
  • Fixed Time Delay 1‑60s
  • Fixed Sense Resistance of 5k‑250kOhms
  • 24, 120, or 230VAC Input Voltages Available
The LLC8 Series is a low cost, single‑probe conductive liquid level control designed for low liquid level cutoff protection. It offers a factory fixed time delay of 1 ‑ 60s and is available for input voltages of 24, 120, or 230VAC. LED indicator illuminates whenever the LLC8's isolated, 10A, SPDT output relay is energized. Sense resistance is fixed from 5K ‑ 250KOhms. Available with manual/ automatic reset or a special manual reset with a power outage feature that auto resets the unit when power is restored and the water level is acceptable. 24 and 120VAC units are UL recognized as limit switches under UL353 (230VAC units are UL 508) and CSA certified under Standard 14.

Automatic Reset (Reset terminals not connected): When liquid rises to the low level cutoff probe, the output relay and the LED indicator energize. When the liquid falls below low level cutoff probe, the output relay and the LED indicator de‑energize after a fixed time delay.

Manual Reset (Reset switch connected): When the liquid level falls below the low level probe, the output relay and LED de‑energize after a fixed time delay. When the liquid level rises to the low level probe, the output relay and LED indicator remain de‑energized until the manual reset switch is opened; then they energize immediately.

Power Outage Manual Reset (Reset switch connected): A power outage causes the output relay and LED indicator to de‑energize. Upon restoration of power, if the liquid level is above the low level probe, the output relay and LED indicator will re‑energize. If the liquid level is below the low level probe, the output relay and LED indicator remain de‑energized until the Normally Closed (NC) reset switch is opened.

  • Isolated, 10A, SPDT Output Contacts
