6.6.1 Modem hardware reset
In the event of unreliable modems, it is possible to carry out a restart or reset by switching off the power supply.
The floating contact of the multifunction relay AUX (terminals 15, 16, 18) can be used for this as interrupt switch
for the modem power supply:

The function of the multifunction relay AUX must be set to modem reset.
If this setting has been selected, the system centre checks the availability of the modem and initiates a
modem hardware reset automatically as required.
If a modem hardware reset is needed, the system centre now switches off the modem for a short time
(approx. 10 seconds) and then switches it on again.
