Selecting the Mode menu will allow the user to place the unit in the Off-line state. If
the state is set to Off-line the relays will be de-energised and the current output level
frozen for the duration of the Off-Line state. When On-Line is selected the relays
and current output will operate normally. The middle LED on the front panel display
will indicate when the unit is
Off-Line .
