restore local control.

3

ALARM

status LED

Red LED, lights if a) OVP, OCP or OTP are triggered, b) command error, c) front
panel operation error, d) emergency shutdown, or e) power supply failure. Refer to
Table B-2 for an explanation of error codes.

status LED

Yellow LED, lights when front panel keys are locked. To lock the front panel keys and
encoder, press SHIFT and tap the encoder. Repeat to unlock the front panel.

5

SHIFT

status LED

The encoder Increases (clockwise) or decreases (counterclockwise) the highlighted
digit of the Voltage or Current display, then press ENTER key to confirm. Tap the
encoder

to change the highlight. The highlighted digit blinks slowly.

7

Output ON/OFF

status LED

Green LED, lights when output is on.

8

OUT on/off

1) Restart of the AC input. (See PAR. 3.3.9 to configure whether unit powers up

with out off at previous setting.)

2). The mains supply is interrupted for more than 100mS.
3) The mains supply exceeds or is under the rated input range more than 500ms.

b. If OCP - OVP - OTP are detected.

ENTER/MENU

dual function key

a. Press ENTER to confirm value set by encoder.
b. Press SHIFT+ENTER to get access to MENU function. See PAR. 3.2.2
c. When output is ON, only limited Menu functions can be changed (see PAR. 3.3.5).

a. Press RCL as many times as needed to view the stored voltage/current settings in
sequence, press ENTER to confirm recall, press V to exit recall function.
b. Press SHIFT + STO to store settings. Rotate encoder to scroll through memory
cells. Press ENTER to store programmed voltage and current settings, press ENTER
to exit storage function.
