Fault Messages
The following warning/alarm information defines each
warning/alarm condition, provides the probable cause for
the condition, and details a remedy or troubleshooting
procedure.
WARNING 1, 10 Volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
This condition can be caused by a short in a connected
potentiometer or improper wiring of the potentiometer.
Troubleshooting
•
Remove the wiring from terminal 50. If the
warning clears, the problem is with the customer
wiring. If the warning does not clear, replace the
control card.
WARNING/ALARM 2, Live zero error
This warning or alarm only appears if programmed by the
user in 6-01 Live Zero Timeout Function. The signal on one
of the analog inputs is less than 50% of the minimum
value programmed for that input. Broken wiring or faulty
device sending the signal can cause this condition.
