Prelube Power Up
If Prelube is enabled (page 22), the programmed pre-
lube sequence occurs.
If no Prelube sequence has been selected, the lube
cycle that was in progress at power down is resumed.
Pump On Ended with Time
If the Pump On sequence has been programmed to be
ended by TIME:
• The GLC 4400 pump output relay activates (J7-3)
and will stay on until the time expires. (see Setup
Menus, Pump On, page 18).
• The Pump On LED (A) remains on during this time.
• The Pump On (C) icon displays.
• The Timer icon (D) displays and indicates the Timer
Mode.
Pump On Ended with Pressure
If the Pump On sequence has been programmed to end
by a pressure switch:
• The GLC 4400 pump output relay activates (J7-3)
and will stay on until a switch closure is received
(J6-3) (see Setup Menus, Pump On, page 19).
• The Pump On LED (A) remains on during this time.
• The Pump On (C) icon displays.
• The Cycle LED (B) illuminates and Pressure Mode
icon (D) displays to indicate the pressure switch.
• If the pressure switch closure is not received before
time expires, an alarm occurs.
NOTE: If Pump On is ended by a pressure switch and
no Power Up delay is selected, when power to the GLC
4400 is turned on, the GLC 4400 starts at the beginning
of the Pump On time instead of resuming the Pump On
time where it left off.
