Low Level Filtering Screen Setup
The Low Level Filtering screen setup is used to filter out
spurious signals from rotating paddle type low level sen-
sors.
NOTE: When using the GLC4400 with the G3 Automatic
Lubrication Pump, it is recommended that the low level
filtering be set to G3 defaults.
The NUMBER field determines how many signal activa-
tions are required to set a fault.
The TIME field determines the amount of RUN time
required without an activation to reset the activation
count to 0 (zero).
MODE Field - (available in Series D or later models
only)
The MODE field determines the behavior of the control-
ler in a low level state. FAULT MODE will stop the pump
when a low level is detected. The Alarm screen must be
cleared before the pump will operate normally.
WARNING MODE will notify the user of a low level
through the low level alarm contact, alarm LED and
ALARM message on the screen. The pump will continue
to operate normally.
NOTE:
• A WARNING MODE forces the number of signals to
1.
• In FAULT MODE when the number of signals is 1,
the user must resolve the low level condition prior to
clearing the error on the controller.
