11.2.1 Outputs
Relay outputs (RL1 .. RL4)
Mode: Disabled
(Disabled, Normally open, Normally closed, Pulsation)
[1]
[1]: In the
Normally open
mode the relay circuit is closed when an event is reported (e.g.
exceeded alarm-control threshold). In the
Normally closed
mode, the relay circuit is
normally closed when idle, and is opened when an event is reported.
Pulsation
-
when an event is reported, the relay circuit is closed and opened at approx. 1Hz
frequency
(e.g. a light indicator blinks - alarm notification). After the acknowledge, the
relay output remains active if the threshold is still exceeded (the indicator is lit). If the
exceeding returns to normal
– the relay output will be inactive. In the
Disabled
mode,
the selected relay output is open.
Note: SSR relays remain open in the event of power failure.
Analog output
Source: Channel 3
(Disabled, Channel 1, .., 6)
[1]
[1]: Selection the output mode as switched off or as a retransmission of the selected
channel value in the form of 4-20mA current loop.
4-20 mA span may be set as a sub-range of retransmitted channel span by entering
the process values for 4 mA and 20 mA respectively.
Failure value: Disabled
(Disabled, Constant)
[3]
[2]: Setting the failure value.
11.3 Communication settings
The window has been divided into two sub-windows: for Ethernet and RS-485
communication settings. Switching between settings windows is possible by using tabs.
Confirm
and cancel
buttons are common for both sub-windows, clicking on
these buttons results in toggles to the Main Menu.

11.3.1 Ethernet port
To ensure proper communication between the device and the master system, all
communication parameters need to be configured.
