96 2012-12-01/00561071 [SCR Power Controller TYA201]
Slave: Attention!
High temp. Device temperature is higher than 100 °C
(excess temperature) - Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er maximum load current
Slave: Limit.
active high temp. Device temperature is higher than 105 °C.
Device 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
Slave: Supply volt.
too low Supply voltage is not within specified toler-
ance range
v Chapter 10.1 "Voltage supply, load
current"
Check nominal voltage of the device
type
v Chapter 1.3 "Order details"
Slave: Supply volt.
too high Supply voltage is not within specified toler-
ance range
v Chapter 10.1 "Voltage supply, load
current"
Check nominal voltage of the device
type
v Chapter 1.3 "Order details"
Slave: Temp.
drop in supply Dangerous temporary equal proportion for
transformer loads has been detected.
v Chapter 5.1.5 "Monitoring"
Ensure stable mains supply.
Inhibit by
inhibit input A firing-pulse inhibit has been triggered via
a potential-free contact.
No power from the power controller.
v Chapter 3.3 "Connection dia-
gram"
Open contact between terminal 7 and
8 at screw terminal X_2.
Inhibit by
ext. inhibit The firing-pulse inhibit has been triggered
via an interface.
v Interface manual "Ext. inhibit"
Soft start phase This message appears in the display until
the soft start has been completed.
v Chapter 5.1.2 "Power controller"
-> Soft start duration
Current limiting
active The required output level causes an exces-
sive load current and is therefore limited to
the set value.
v Chapter 5.1.2 "Power controller"
"Current limiting" on page 57
Resistance
limitation active The desired output level leads to current/
voltage values that exceed the set load re-
sistance. The output level is limited to the
permissible resistance to prevent overheat-
ing.
v Chapter 5.1.2 "Power controller"
-> Resistance limitation
