5.3.1 Cabinet Spill Detection
Sump Spill (Dual Float Sensors)
The ChemGuard® CG050 is equipped with dual float switches as standard offering for spill
detection. When a single float detects a spill, a fault alarm is displayed. If both float switches
detect a spill, a shutdown alarm will be generated and will terminate all operations and return
the cabinet to IDEL state.
NOTE
: The Dual Float Sensors (SUMP SPILL) does not require any calibration, it is
recommended to verify the floats move freely by lifting each one up and it should free
fall down. Verify no build-up on the Float and Stem which can cause hang-up.
Please refer to Chapter 7 for more detail test on the Sump Spill (Dual Float Sensors).
