10.19 Undervoltage detection
(as of software 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 11.
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 tol-
erance 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 toler-
ance range. An external voltage monitor must be connected to prevent defective heatseals as a
result of low line voltage.
