Undervoltage detection
Trouble-free operation of the temperature controller is guaranteed within the line voltage and 24 VDC supply
voltage tolerances specified in section 13 "How to order" on page 59.
If the 24 VDC supply voltage drops below the permitted lower limit, the controller is switched to standby mode. No
more heatsealing processes take place and no more measuring impulses are generated. Normal operation is
resumed when the input voltage returns to the specified tolerance range again.
Standby mode is indicated by 0…3 °C (i.e. approx. 0 V) at the analog output. In addition, the SA bit is set in the
status word for the cyclic output data.
Trouble-free operation of the controller is only guaranteed within the specified tolerance range of
the input voltage. An external voltage monitor must be connected to prevent low line or 24 VDC
supply voltage from resulting in defective heatseals.
