1.3.3 Additional safety devices
Emergency strategy – isolate the power supply!
Do this by turning the
>Mains switch< [37] to the “0” position!
1.3.3.1 Auto-Start function
Following a power outage (or when switching on the temperature control unit), this function can be
used to determine how the temperature control unit is supposed to respond.
Standard setting (OFF):
OFF
Once the temperature control unit is switched on, the temperature control process is
started only after manual input.
ON The temperature control unit is restored to the same status as it was before the power
failure. For example, before the mains failure: temperature is off, according to this setting,
after the power is restored temperature control is off.
Automatic power outage mechanism:
If temperature control is active during a power outage, the process will automatically continue after
the power outage.
Further information can be found on page 34 in section
»Setting the Auto-Start function (automatic
mains failure)« .
1.3.3.2 Alarm functions
An alarm is a system state that signals unfavorable process conditions. The temperature control unit
can be programmed so that the plant operator is warned when defined limit values are exceeded.
The response of the temperature control unit to an alarm can be determined. Possible responses
are: Switch off temperature control or control temperature to a safe setpoint (2nd setpoint).
