5 Configuration
66 V1.04/EN/00561071 [Thyristor Power Switch TYA 201]
5.1.5 Monitoring
This allows an internal measurand to be monitored for compliance with limit
values.
Depending on the switching behavior, an overrange or underrange is output at
the digital output (option: relay or optocoupler).

Load voltage These measurands can be monitored and are dependent on
the ordered device type.
Note:
If Power controller -> Thyristor control -> Logic (switch) and
Monitoring -> Limit value monitoring -> Load voltage, load
current, power (in W), or power (in kW) is selected,
the limit value monitoring only operates in the periods in which
the thyristors have been fired.
If the thyristors are blocked, as a general rule, the min. and
max. alarms are switched off.

Min. limit value
alarm 0 to 9999.9 The absolute minimum limit values for load voltage, load cur-
rent, power, resistance, mains voltage, or device temperature
can be monitored.
If the measurand falls below this value, an error message ap-
pears at the bottom of the display and the yellow K1 LED
lights up. Depending on the set control direction, the digital
output switches as shown in the diagram.
The unit of the limit value corresponds to the measurand to be
monitored.
Max. limit value
alarm 0 to 9999.9 The absolute maximum limit values for load voltage, load cur-
rent, power, resistance, mains voltage, or device temperature
can be monitored.
If the measurand exceeds this value, an error message ap-
pears at the bottom of the display and the yellow K1 LED
lights up.
Depending on the set control direction, the digital output
switches as shown in the diagram.
The unit of the limit value corresponds to the measurand to be
monitored.
