Figure 3.3 Set over current trip
With the power supply configured for rotary input, voltage and current set point commands are
entered with the front panel potentiometers and over voltage trip and over current trip are entered
with the up/down keys.
To set over voltage trip or over current trip, press the menu key. The OVT (over voltage trip)
LED will initially flash. This indicates that an up/down entry will create a new OVT set point.
Pressing the item key causes the OCT (over current trip) LED to flash indicating that an up/down
entry will create a new OCT set point. After the change is made, the enter key must be pressed
to save the new set point or the clear key can be pressed to exit without saving the new set point.
In all control modes, set point voltage and current can be quickly displayed by simply pressing
the V/I dis key. Similarly, set points for OVT and OCT can be displayed by pressing the trip dis
key.
The up/down keys have an acceleration feature to speed up entries. Pressing and holding the
