Possible cause
No supply voltage
Wiring fault
Generator earth wire not
connected
No signal on the
Remote On/Off input
High voltage set too low
Label or labels between
electrodes and earth are too
small or not present,
arcing between electrode and
mould
Output voltage set too high,
arcing on electrode
Short circuit between electrode
or HV cable and earth
Supply voltage too low
"Cycle OK" output overloaded
Generator overheated
Solution
Switch on 24 V DC supply

Locate fault and remedy, see 5.3
Connect generator earth wire,

"Remote On/Off" input
Increase output voltage by
increasing setpoint (5.3/6.2)
Check presence or size of
label(s)
Insulate electrode or increase
distance to (part of) mould
Reduce output voltage by
reducing setpoint or increasing
distance to earth
Locate short circuit and eliminate
