102 V1.04/EN/00561071 [Thyristor Power Switch TYA 201]
Limiting active
high temperature Device temperature is higher than 105 °C.
Device is too hot, output level is reduced!
(Limited power due to excess temperature)
- Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er maximum load current
Mains voltage is
too low Mains voltage is not within specified toler-
ance range
v
Chapter 10.1 "Voltage supply, load
current"
Check nominal voltage of the device
type

gram"
- Eliminate mains disturbances
Wire break
Current input Input current too small for the selected
measuring range. - Check wiring for wire breaks and
reverse polarity.
- Check upstream devices (con-
trollers)
Wire break
Voltage input Input voltage too small for the selected
measuring range. - Check wiring for wire breaks and
reverse polarity.
- Check upstream devices (con-
trollers)
Malfunction
Bus error No connection to the Profibus master Check wiring and master device (PLC).
Master-slave
Error in comm. Error in the data transfer between master
and slave Is the 1:1 patch cable plug connected
correctly?
Data cable
faulty Communication between master and slave
interrupted. Check the 1:1 patch cable and replace,
if necessary
Synchronization
failed Slave device switched off or communica-
tion between master and slave interrupted Check plug connection of 1:1 patch
cable or voltage supply
