Cause
Device temperature is higher than 105 °C.
Device too hot!
Output level is reduced.
(Limited power due to excess temperature)
Mains voltage is not within specified toler-
ance range
v Chapter 10.1 "Voltage supply, load
current"
Mains voltage is not within specified toler-
ance range
v Chapter 10.1 "Voltage supply, load
current"
Dangerous temporary equal proportion for
transformer loads has been detected.
v Chapter 5.1.5 "Monitoring"
A firing pulse inhibit has been triggered via
a potential-free contact.
No power from the power controller.
The firing pulse inhibit has been triggered
via an interface.
This message appears in the display until
the soft start has been completed.
The required output level causes an exces-
sive load current and is limited to the set
value.
The desired output level leads to current/
voltage values that exceed the set load re-
sistance. The output level is limited to the
admissible resistance to prevent overheat-
ing.
V1.04/EN/00561071 [Thyristor Power Switch TYA 201]
Remedy
- Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er maximum load current
