Pump cycle / interval time
No control unit LC502
99 = none EB = 4 min. run time / 1 h interval time. Factory setting, additional setting times on request
Voltage key
912 = 12 V DC (only available for vehicle application version) 924 = 24 V DC 486 = 90–264 V AC (not available for vehicle application version)

1) For technical reasons, the first pump element must always be installed at outlet 1 in SKF MonoFlex systems
2) If the relief valve is configured together with several pump elements, then the lines leading from the pump elements will be joined together ahead of the relief valve
