Fault detection |
|
Preventive - abnormal supply voltage
|
supply 1 or supply 2 is < 18 Vdc (Under
Voltage, UV) or > 30 Vdc (Over Voltage, OV).
|
|
Critical - abnormal supply voltages or cumulative fault
|
both supplies are in
under (< 18 Vdc) or over (> 30 Vdc) voltage condition OR cumulative fault indication
(about presence of short or open field circuit for any DO channel).
