① The setpoints (stored or being programmed) must match the specified DPGDS setpoints.
② When oil pressure drops to within 5PSI (34kPa) of the P013 or P014 setpoint, a low oil pressure alarm is issued by the GSC+.
③ When coolant temperature rises to within 11ºF (6ºC) of the P015 setpoint, a high coolant temperature alarm is issued by the GSC+.
④ The values other than the default (700V) are for switchgear applications and require the use of external potential transformers and the removal of the AC voltage range jumper located in the relay module.
The DPGDS unit is factory configured for the 5.20 K value. See the Caterpillar Electronic Modular Control Panel II+ manual topic AC Voltage Range Selection in the Testing and Adjusting section.
⑤ After setpoint P022 is reprogrammed, the GSC+ must be power cycled (powered down and then powered up)
