] keys. The internal relay 1 then switches on when this
value is reached. Save the value by pushing the two keys
simultaneously.
l
Set the function switch to position [ 2] (relay 1 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.
l If you want to control additional relays, proceed 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.
