SP FAULT CODE TROUBLESHOOTING PROCEDURES
TROUBLESHOOTING USING SP FAULT CODES
SP (Spare Input) Fault Codes are associated with four inputs that are considered spare inputs. Spare fault code
programming is contained in OP6-0, Protective Relay Programming (see WP 0085, Table 7 for details). These
codes are not stored in the GSC fault log. When a spare input fault is detected, the FAULT SHUTDOWN lamp
flashes and the corresponding code (SP1, SP2, etc.) is displayed on the upper GSC display. Fault condition on SP
1 and 4 is programmed to shut down the engine immediately.
Fuels used in the generator set are flammable. When filling the fuel tank, maintain metal-to-metal
contact between filler nozzle and fuel tank opening to eliminate static electrical discharge. Failure
to comply can result in flames and possible explosion and cause injury or death to personnel and
damage to the generator set.
Fuels used with the generator set are flammable. Do not smoke or use open flames when
performing maintenance. Failure to comply can result in flames and possible explosion and can
cause injury or death to personnel and damage to the generator set.
SP1 thru SP4 must be evaluated using dedicated shutdown lights, alarm conditions, and
available fault codes.
