NOTE: Upon receipt of LIST:SET:TRIG command (PAR B.89), the Output Off flag (EXT_C/EXT_E) no longer represents output on/
off state. Instead, this signal can be used to trigger an external device. The transistor state (conducting or not conducting)
and the pulse width duration is controlled by the LIST:SET:TRIG command. Upon receipt of LIST:CLE command (PAR
B.57) the Output Off flag reverts to representing output on/off status as described above.

PRELIMINARY OPERATIONAL CHECK

A simple operational check after unpacking and before equipment installation is advisable to
ascertain whether the power supply has suffered damage resulting from shipping.
Refer to Figures 2-1 and 3-1 for location of operating controls and electrical connections. Tables
3-1 and 3-2 explain the functions of operating controls/indicators and keypad keys, respectively.
Refer to PAR. 3.2 for a description of basic operating techniques.
With both control and power boost section POWER switches set to off position, connect
1.
the power supply to source power
2. With no load connected,
the ON position.
alphanumeric display (LCD) shows the processor firmware revision history and lists various
tests performed during the internal self-test. As each test is completed, PASS or FAIL is dis-
played. If all tests pass, the unit goes into the default mode. If a failure occurs, the failure is
displayed. Figure 3-4 shows the factory configured power on defaults displayed on the LCD.
3. Connect a digital voltmeter (DVM) (resolution and accuracy of 0.01% or better) to the OUT S
and COM S terminals at the rear panel terminal block (7,, Figure 2-1).
4. Use the keypad to enter the rated maximum voltage of the power supply (e.g., enter 36 for a
model BOP 36-56MG) and press ENTER. If STANDBY indicator is lit, press STANDBY key.

FUNCTION
Cathode of LED optocoupler (through a 510 ohm resistor) which is
used for external isolated shutdown. Anode of LED is connected to
(A2A5J7) pin 2. A positive voltage (3.5 to 15V) at pin 2 (referenced to
pin 1) shuts down the unit functionality. The unit remains powered,
but no output is available and the red front panel FAULT LED will go
ON. Response is relatively fast (100
operation it is necessary to cycle power off, then on (preferred) or
briefly press the RESET key on the front panel keypad.
Anode of LED optocoupler which is used for external isolated shut-
down. (See pin 1 above.)
Collector of optocoupler-transistor which is used for external isolated
"power OK" flag. Transistor emitter is connected to (A2A5J7) pin 4.
When unit is operating normally, transistor is saturated. Current
through transistor should not exceed 5mA and supply voltage should
not exceed 15V.
Emitter of optocoupler-transistor which is used for external isolated
"power OK" flag. (See pin 3 above.)
Collector of optocoupler-transistor which is used for external isolated
"Output OFF" flag. Transistor emitter is connected to (A2A5J7) pin 6.
When output is OFF, transistor is saturated. Current through transis-
tor should not exceed 3mA and supply voltage should not exceed
15V. See NOTE below for alternate function.
