The load is not monitored.
Note:
This parameter is only available if the device type is equipped
2
with an I, I , or P subordinate control loop and the current can
therefore be measured.
v Chapter 6 "Special device functions"
Note:
This setting is only available if load monitoring has been set
to undercurrent or overcurrent.
Partial load failure or partial load short circuit:
This setting specifies the percentage by which the load resis-
tance must have decreased or increased for a load error to be
triggered.
Default setting (suitable for most load types)
Especially suitable for short-wave infrared radiators
The Teach-In value is automatically determined once after
each power ON.
v Chapter 6.1.1 "Teach-In"
Teach-in can be performed in manual mode or in the opera-
tor level.
v Chapter 6.2.2 "Configuring Teach-In (prerequisite for
Teach-In in manual mode)"
v Chapter 4.2.4 "Monitoring"
Teach-In is performed cyclically at a time interval of 1 minute.
No monitoring
If the effective values of the analyzed half-waves are more
than 10 % apart, an alarm message is displayed and the digi-
tal output for the collective alarm switches depending on the
set control direction.
Immediate firing pulse inhibit prevents the connected trans-
former loads from destroying the semiconductor fuse due to a
DC component.
If there are no further mains voltage drops, the firing pulse in-
hibit is removed and the power controller continues operation
(e.g. with a soft start).
No monitoring
Control loop monitoring is used mostly for monitoring SIC
heating elements. It uses a binary signal to indicate when the
power required by the setpoint specification can no longer be
reached with the load present, potentially due to aging of the
heating elements.
This error is shown in the info line when the actual value of the
subordinate control loop is smaller than the required setpoint
value for an uninterrupted period of 15 minutes.
