Signal settings: Signal groups sub-menu

Only channels that are selected in groups are displayed and saved.

Summarise analogue and/or digital signals in groups such that you can call up the important infor-

mation in operation at the push of a button (e.g. temperatures, signals in system part 1, ...).

Maximum 8 channels can be allocated to a group.

Relay 2 (3, 4, 5) in LV Signal settings -> Digital outputs, Position 2-5:

Function of the relay in case of a limit value, i.e. when it is activated.

“Closing”: in case of a LV the corresponding connections (shown in brackets) are shorted, opened in idle status.

“Opening”: in case of a LV the corresponding connections (shown in brackets) are opened, shorted in idle status.

! Note!

In this operating mode, the relay coil is energised in normal operation, i.e. you can also use it as a message for a power

failure since it then reports limit values or power failure by shorting contacts (“Maximum safety”).

Open collector (option) Function of the open collector output in case of a limit value, i.e. activated.

! Note!

The open collector is an NPN transistor, terminal 98 = collector, terminal 99 = emitter, i.e. reference potential.

Relays 12-17 in LV Settings as under position 2.

Set-up -> Signal settings -> Digital outputs (Relays/OC)

Set-up -> Signal settings -> Signal groups -> Group x

Identifier Relevant designation of the signals allocated to a group, e.g. temperatures, quantities, system part 1, ...

Operating mode Specifies how the measured values are displayed and saved.

“Instantaneous values”: the current values at the time of memory are saved.

“Averages”: the averages since the last time of memory are determined and saved.

Example with memory cycle of 1 minute: the arithmetic mean is calculated and saved from 60 values, one measured

every second.

“Envelope curve”: the minimum and maximum since the last time of memory are determined and saved.

Example with memory cycle of 1 minute: the lowest and the highest value is calculated and saved from 60 values, one

measured every second. These values are linked with a line in the graph, displayed and saved. The digital display shows

the current (instantaneous) value in normal operation - updated every second.

! Note!

In this operating mode, only 4 channels per group are possible.
