SERVICE
SAFETY INSTRUCTIONS
Read these safety instructions, as well as the applicable installation, operating and servicing instructions
contained in this manual before using the power supply.
Do not touch the output terminals. The high voltage output is dangerous. Electric shock can cause injury or
death.
Do not remove the cover or disassemble the unit. There are no operator serviceable components or
adjustments inside the unit. High voltage components inside the unit can cause serious injury even with
input power disconnected.
CAUTION
If this power supply is used in OEM equipment, the OEM equipment manufacturer is responsible for
attaching appropriate warning labels on the OEM equipment.
Operating the power supply outside the specified limits for input voltage, temperature, or other environ-
mental conditions noted in this manual can damage the power supply and void the warranty.
Safety Messages
The BHK-MG can be controlled by digital and/or analog inputs. When the output is disabled, whether by
the OUTPUT ON/OFF key, SCPI command via GPIB or RS 232 interface, or via the Status and Remote
On/Off Port, an internal solid-state switch sets the voltage/current references to zero, resulting in zero out-
put from the power supply. In the case of the OUTPUT ON/OFF key or SCPI command, if the solid state
switch fails, and the output is higher than 8V, and the current is higher than two LSBs, a shutdown
sequence begins: the unit beeps and flashes the message
Power Down in XX sec
for 10 seconds as
XX counts down from 10 to 0. After 10 seconds the input circuit breaker trips OFF. If the circuit breaker
does not trip OFF,
BHK Failure
is displayed on the LCD.
There are no operator serviceable parts inside the case. Service must be referred to authorized personnel.
