POTENTIAL FREE ALARM CONTACT
The purpose of having the potential free contact (CTS) is to make it possible to receive a signal
when the controller of the freezer registers some kind of error. By using the potential free contact,
it is ensured to receive the signal regardless of which kind of surveillance system is used.
As the potential free contact works like a switch on/off contact, it is independent of any possible
software or hardware that might be used in the surveillance system.
You CANNOT se WHAT caused the setting of the alarm, but only that an alarm has been set off
and therefore has to be checked in order to locate the problem.
