6 Special device functions
6.6 Monitoring of the mains voltage drop
If the effective values of the analyzed half-waves are more than 10 % apart, an
alarm message is displayed and the binary output for the collective alarm
switches depending on the set control direction.
Immediate firing pulse inhibit prevents the connected transformer loads from
destroying the semiconductor fuse due to a DC component.If there are no fur-
ther mains voltage drops, the firing pulse inhibit is removed and the power
controller continues operation (e.g. with a soft start).
Default setting
Monitoring is not activated.
v
6.7 Firing pulse inhibit
The inhibit function serves to protect the thyristor power controller and the
connected devices.
Internal
The thyristor output is locked during:
- Device switch-on (during the startup procedure)
- Changes in the configuration level
- Insufficient or excessive voltage supply
- Master/slave data line interruption
- Master/slave synchronization failure
- Setup of data transfer to the device
- Device temperature greater than 115 °C
- Rotary field error
- Short-term supply drops > 10 % within a half-wave
v
External
Via the "Inhibit" digital input
v
Alternatively, the thyristor output can also be switched off via the PROFIBUS
or RS422/485 interfaces.
