Low Main voltage
Trigger voltage less than 150 +/- 10 VAC).

VAC).
12.3 Fault counters
Each fault code has his own fault counter. If a fault occurs the according fault is enhanced. This way the total
number of times a fault occurred, is known.
12.4 Fault history
This list gives information about recent faults and how many times they occurred and therefore may help to solve a
problem. When a new fault occurs, all faults already present in the list are shifted one place to the end and the new
fault is stored at the beginning of the list. The fault history list can contain up to 20 faults.
12.5 Additional H.D. counter
ESYS counts situation when is running sparking, safety time is not elapsed and H.D. is end immediately. After
Post-purge phase, it's holding in Stand-by and waiting for next H.D. comes from DFGT.
Directly after 4th positive edge (only 3 could be executed) of the heat demand within time “Period H.D. events“
after the first heat demand, the ESYS should go into lockout state where stays for defined time “H.D. over-count
delay“.
• The number allowed heat demand is always constant 3 in sw.
• If period timer run out (start with the first heat demand), the heat demand counter should go back to 0.
• If there is a successful ignition, the heat demand counter should go back to 0.
