10.4.2. Watchdog
Watchdog function
This temperature system provides a watchdog function for
monitoring the digital interface (RS232, USB, Ethernet) with the
temperature system being in remote control mode.
In case of a disturbance/failure in the superordinate data system
the watchdog function ensures the temperature system enters a
defined operating state.
In the defined operating state the temperature system accepts the
watchdog setpoint as setpoint for continuing temperature control.
The watchdog setpoint
must
thus be set to an uncritical value
depending on the application task
To activate the watchdog function the remote control must be
switched off first.
