Undervoltage detection
(As of SW revision 007)
Trouble-free operation of the temperature controller is
guaranteed within the line voltage tolerance range
specified in section 6 "Technical data" on page 8.
If a line voltage which is less than the lower limit of the
permissible range occurs, the controller is switched to
a standby mode. No more heatsealing processes take
place and no more measuring impulses are generated.
The display changes to indicate this.
The main menu is displayed again, and operation is
resumed, when the input voltage returns to the
specified tolerance range.
The standby mode is indicated by 0°C (corresponds to
0V) at the analog output.
Trouble-free operation of the controller is
only guaranteed within the specified input
voltage tolerance range. An external voltage
monitor must be connected to prevent defective
heatseals as a result of low line voltage.
