11.1.4 Sensor break alarm
Alarm is generated after the set delay expires
(Menu 6-2-1)
if the controller detects breakage or short circuit on
a sensor. This delay time is global for the controller and applies equally for all sensors.
11.1.5 Hardware fault alarm
Alarm is generated without delay if the controller detects hardware problems. Malfunction of the following
components is detected:
•
Temperature measurement
•
General fault
•
Loss of setpoint (memory problems)
•
Time/date
•
First start
Priority for transmitting the alarm is governed by the controller priority and type of alarm.
11.1.6 Alarm routes
A detected alarm state is transmitted by the controller by the following routes:
•
at the alarm relay (floating changeover contact 15/16/18)
•
a local BT 300 x Operator Interface connected to DISPLAY interface
•
via the CAN bus interface on a system centre / store computer / operator terminal in the E*LDS-System.
The manual reset of the alarm / alarm state can be performed
•
By switching off the controller, regardless of whether the alarm is still active
•
On a local BT 300 x Operator Interface connected to the display port
•
via the CAN bus interface using a system centre / store computer / operator terminal in the E*LDS-System.
Sensor break alarm is only generated when priority of the sensor concerned is set to a value other
than "-".
