8.3 Historique des défaillances
Faults history is only available if the extensive menu is activated. DIP 8.
Faults history (See fig. 3 - menu 2-3) shows the nine most recent faults and the current fault using a code number.
Faults history is designed so that the fault that occurred longest ago (Fault F9) disappears as soon as a new one occurs and has been stored in the
memory.
When the first element of the menu reads F0, a fault exists, and can then be identified by its code number.
Code No. Description
E00 Dry running level
E40 Transmitter failure
E42 Transmission wire cut
E60 Excessive pressure fault
E81 Pump 1 failure
E82 Pump 2 failure
E83 Pump 3 failure
E84 Pump 4 failure
The whole faults history can be erased by means of the last element in the "CLr" menu.
If fault numbers other than those indicated above appear, the box itself is faulty: contact the SALMSON Maintenance Department.
