4.3. TURNING THE POWER SUPPLY ON
Turn the
unit on using the front panel a-c
POWER
ON/OFF switch/
circuit breaker (see Figure 1).
CAUTION: DO NOT repeat-
edly toggle the ON/OFF switch as this may cause unit
to fault.
If actuator does not lock when released, wait a few
seconds before trying again. The circuit breaker is “trip-
free;” if overload exists, contacts cannot be held closed by
actuator.
When the power supply is turned on, the LCD first shows
the power supply type, e.g., Kepco
ATE25-40 GPIB
addr. = nn
, where nn is the GPIB address (factory
default GPIB address = 6). The LCD then shows the power
on defaults (see Figure 2). The defaults are: output
enabled, voltage mode, output voltage set to zero, output
current set to a minimum value (1-2% of
I
O
max). Power on
defaults also include setting maximum values for overcur-
rent and overvoltage protection listed in the full Operator
Manual (see PAR. 1.1).
When the power supply is turned on, it is automatically set
to Local mode. For remote operation, or to lock the keypad,
refer to the full Operator Manual (see PAR. 1.1).
4.3.1. LCD CONTRAST.
If necessary the LCD contrast
can be adjusted by pressing
MENU
key once (with the
power supply in command entry status ). Then press
or
key to increase or decrease contrast for optimum
viewing. Press
ENTER
or
CLEAR
to exit menu.
4.3.2. AUDIBLE BEEPS.
With the power supply in com-
mand entry status , press
MENU
key three times. The top
line indicates if the speaker is on or off (the factory default
setting is speaker on). Enter
