Low Level Sensor
When grease is present the LED is green. When the
lubricant level in the reservoir reaches approximately
30% (low level), the LED turns to an amber color. See
FIG. 3 and the table below.
At 30% capacity, the amber low level signals the tank is
reaching a point where the operator should refill the
tank. There is still lubricant in the tank and immediate
shutdown in not required.
If you are using a GLC2200 (part number 24N468,
Series F or later only), the system will enter a low level
warning condition (LL03) after the switch input is closed
for more than 1 second. However, the pump continues
to operate.

Keep the sensor protective cover (12c on page 17)
installed to prevent sensor damage.
Low level sensor wiring instructions begin below.
Graco GLC2200 (part number 24N468, Series F or later
only) can be used to run the pump and monitor the low
level. Refer to FIG. 5 for Low Level Sensor wiring in sys-
tems controlled with a GLC2200. A Low Level Sensor
cable (part number 129072) and a GLC2200 Wiring
Harness (part number 24P314) are required.
