OUTPUT ON/OFF  The OUTPUT ON/OFF key toggles the output relay on or off. 
The state of the output relay is reflected by the green LED 
located directly to the left of the OUTPUT ON/OFF key. If the 
green LED is lit, the output relay is enabled (closed) and the 
programmed output voltage is present at the output terminals. If 
the green LED is off, the output relay is open and both the 
HIGH and LO terminal of the output terminal block are 
disconnected from the power source. In this mode, the output is 
floating. The ON/OFF button provides a convenient way to 
disconnect the load without having to remove any wires. 
PHASE  The PHASE key is used to select the phase on a RS90. 
Pressing the PHASE key will toggle phase A, B, C or ABC. 
Some screens may not support the ABC or show all phase 
information in which case this mode is skipped. 
SET  The SET key is used to select the mode of operation of the 
shuttle. Refer to section 4.1.1 for details on its operation and the 
use of the SET key. 
+/-  The +/- key can be used to toggle the sign for those parameters 
for which it is relevant. This is typically the output voltage when 
in DC mode of operation.  For fields that have only two possible 
values such as the voltage range field, the +/- key can be used 
to toggle between these two values.
