signal loss occurs. The system relay REL04 responds.
• You can combine Remote Out 2 with PROD_FEEDBACK (product
feedback via mA-output).
• If the relays are defined as status feedback, they switch directly according
to the current status (see above). A delay time for the limit values is not
effected. Set limit values remain valid. It is still indicated by the limit value
LEDs on the front panel when values exceed or fall below the set limit
values.
