Liquid Level Control
Function of the liquid level control
Switches off and on the carbonator pump and motor when the electrodes indicate a full or
empty tank. Continuity across L and H to G cause the liquid level control to switch off the
carbonator pump and motor. Open circuits across L and H to G cause the liquid level control to
switch on the carbonator pump and motor.
Failure of the liquid level control
Defective liquid level control will cause the carbonator pump and motor to run continuously or
not at all.
Note: For proper voltage meter reading, you must test to ground or you will get a ghost reading.
Notes:
w 90% control fails closed (motor runs all the time)
10% control fails open (motor does not run)
w If you start two pumps with one liquid level control, you must use the heavy duty 15 AMP
control (P.N. 208162)
