6.4.1 Configuration of the relays
The device has two relays with limit values that are either switched off or can be allocated to
the input signal. The limit value is entered as a numerical value including the position of the
decimal point. The way the changeover contact is wired ((→  35)) determines whether
the relays act as an NO or NC relay. Limit values are always assigned to a relay. Each relay can
be assigned a channel or calculated value. In "Error" mode, the relay acts as an alarm relay and
switches for each error or alarm.
