Maintenance and fault rectification
Relay
Set the function switch to position [ 1 ] (relay 1
l
on). For the given example, select the value
90.0 (90.0 %) with the [ +/- ] keys. The internal
relay 1 then switches on when this value is
reached. Save the value by pushing the two
keys simultaneously.
Set the function switch to position [ 2] (relay 1
l
off). Select the value 10.0 (10.0 %) with the [
+/-] keys. The internal relay 1 then switches off
when the value falls below this value. The
respective relay control lamp lights when the
relay is energized. If the switching points are
too close together (<0.1 %), the appropriate
LED flashes. The relay takes on the safe
condition. In mode "OPERATE " an error
message is outputted on the display.
If you want to control additional relays, proceed
l
in the same way, as with relay 1. The switch
positions for setting the respective relays are
stated in the list of the function switch under
"Setup procedure".
Note:
If you want to change the mode (i.e. the
switching function of the relays), you have
to exchange the On and Off values.
