Illustration 28: Alarm Example
6.9.3 WARNING 1, 10 Volts Low
Cause
The control card voltage is less than 10 V from terminal 50. Remove some of the load from terminal 50, as the 10 V supply is overloa-
ded. Maximum 15 mA or minimum 590 Ω.
A short circuit in a connected potentiometer or incorrect wiring of the potentiometer can cause this condition.
Troubleshooting
Remove the wiring from terminal 50.
If the warning clears, the problem is with the wiring.
If the warning does not clear, replace the control card.
6.9.4 WARNING/ALARM 2, Live Zero Error
Cause
This warning or alarm only appears if programmed in
parameter 6-01 Live Zero Timeout Function
. The signal on 1 of the analog inputs
is less than 50% of the minimum value programmed for that input. Broken wiring or a faulty device sending the signal can cause
this condition.
Troubleshooting
Check connections on all analog mains terminals.
