3.2.2
TURNING THE POWER SUPPLY ON
CAUTION: DO
NOT
REPEATEDLY TOGGLE THE CIRCUIT BREAKER/SWITCH AS THIS
MAY CAUSE UNIT TO FAULT. ALLOW THE UNIT TO BE OFF FOR AT LEAST
THREE (3) SECONDS BEFORE TURNING THE UNIT BACK ON TO GIVE THE
POWER LOSS CIRCUIT TIME TO RESET.
Set Power ON/OFF circuit breaker/switch on front panel to the up position to turn the power sup-
ply on. If actuator does not lock when released, wait a few seconds before trying again. The cir-
cuit breaker is “trip-free” design; if overload exists or the protection is activated, contacts cannot
be held closed by actuator. Setting the circuity breaker/switch to the down position shuts the
power supply off.
When the power supply is turned on, the LCD briefly displays self test messages, then displays
the power supply type on the top line (e.g., Kepco
BHK 500
) and
GPIB addr. = nn
on the
bottom line, where BHK 500 is model BHK 500-0.4MG and nn is the GPIB address (factory
default GPIB address = 6). After a few seconds, the bottom line of the LCD displays the voltage
and current at the BHK-MG output. The top line displays either
OFF
or the current status of the
unit as shown in Figure 3-1. The status of the unit upon power-up can be changed using the
MENU key as detailed in PAR. 3.2.7.4. Power on defaults also include setting maximum values
for overcurrent and overvoltage protection (PAR. 1.4.4), but are not displayed. If the unit fails a
self-test, the LCD shows the last successful operation, and the unit beeps continually.
If the unit fails self-test during power-up, error messages are shown on the LCD. The failure will
usually cause the test to be repeated, and if the unit passes the second test, power-up contin-
ues and the error message disappears. Refer to PAR. 3.2.3 for details.
