Displayed and actual fault current
WARNING
Risk of electric shock
May cause death or serious injury
The fault current is the current value averaged over 200 half-waves in case of half-wave
control. Due to the pulse pattern of semi-wave control, the fault current in individual semi-
waves may be higher than the displayed fault current.
Determining fault peak current
Peak fault current can be determined using a setpoint value correction:
Peak fault current = fault current / setpoint
Example: Fault current 400 mA; setpoint value 80%
Peak fault current = 400 mA / 0.8 = 500 mA
9.7.11
Monitoring of output control
When using power control, reaching the nominal output is monitored. If nominal output is not
achieved at 100%, an error message is generated. This does not cause the output to switch
off, heating is still possible.
9.7.12
Monitoring of adaptive soft start
When using a control type with adaptive soft start, it is monitored whether the connected
heating element can actually be controlled by the POM. If this is not possible, an error
message is generated. The channel is not controlled in that case. The error message then
disappears when switching off the heater.
