container empty
Reset button (25, Fig. 3-94:) Depressing reset button (25) for more than 2 seconds initiates an additional greasing cycle. After having rectified a malfunction, reset button (25) must be depressed shortly (1 second) to cancel the fault message.
The malfunctions mentioned above prevent the pistons in the monitored distributor from moving up and down. Lamp (24) will then indicate the corresponding fault by flashing on and off in the following intervals: Malfunction of lubricating circuit 1 B = 0,5 seconds - "ON" - 1 second "OFF" Malfunction of lubricating circuit 2 C = 1 second - "ON" - 0,5 seconds "OFF" Malfunction of lubricating circuit 1 and 2 D = 2 seconds - "ON" - 2 seconds "OFF" Container empty (option) Indicator lamp (24) flashes in the following intervals E = 0,5 seconds - "ON" - 0,5 seconds " OFF" The "container empty" signal starts flashing only after 6 revolutions of the motor.
In the event of malfunction, the piston sensor (initiator) can no longer detect piston movements and therefore not switch off the motor.
Fig. 3-94:
The monitoring timer of the control unit operating in parallel switches off the pump after the monitoring time has elapsed. The system indicates a fault. Indicator lamp (24) flashes on and off. The pump does not restart automatically.
