Monitoring; Monitoring The Mains Voltage; Device Temperature Monitoring - Advanced Energy THYRO-AX Manual

The fault signaling relay K1 is fitted with a changeover. Messages which
lead to the switching of the fault signaling relay can be configured with
the control panel, with a bus module, or with the Thyro-Tool AX. With
the default setting the fault signaling relay K1 works in accordance with
the closed circuit principle.
In the case of the following errors the fault signaling relay de-energizes
and the power controller switches off:
• SYNC error
• internal error
• undervoltage in mains
• master/slave error
• error rotating field/phase
In the case of the following errors the fault signaling relay drops out,
the power controller continues to run and a notification is sent (touch
display):
• excess temperature
• undercurrent in the load circuit

6.9 MONITORING

Power controller and load circuit are monitored for errors. Messages
are sent via the touch display, via a bus, or through the fault signaling
relay K1 (see chapter Fault signaling relay K1).
The feature of monitoring (e.g. voltage or temperature) can be deacti-
vated by Thyro-Tool AX software. In this case the adjusted limits will be
disregarded and no message will be shown.

6.9.1 MONITORING THE MAINS VOLTAGE

NOTE
LIMITS OF THE VOLTAGE MONITORING
There are the following limits to the voltage monitoring:
- undervoltage monitoring: < 24 V
- overvoltage monitoring: +10% of the type voltage
This results in absolute limits for the monitoring of the mains voltage.
TYPE UNDERVOLTAGE OVERVOLTAGE
LIMIT LIMIT
230 V 24 V 253 V
400 V 24 V 440 V
500 V 24 V 550 V
600 V 24 V 660 V
TAB. 7 LIMITS OF MAINS VOLTAGE MONITORING
In the default setting the pulse inhibition is switched internally if voltage
drops below the undervoltage limit and the fault signaling relay K1 de-
energizes (both can be configured).

6.9.2 DEVICE TEMPERATURE MONITORING

NOTE
DEFAULT SETTING
The function explained here is described in its default setting.
This setting can be altered with the control panel, with a bus module, or
with the Thyro-Tool AX.
The Thyro-AX is fitted with temperature monitoring. If the power con-
troller dependent temperature is exceeded an event message is sent
(see chapter Fault and status messages). The pulse inhibition is trigge-
red as configured by default setting, but can be deactivated. Please
note when it is deactivated, in case of fault there is the risk of overheat
or damage of the device.
