2.3 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.
1. With power supply disconnected from source power verify that sense connections are cor-
rect: +S is connected to +POS and –S is connected to –NEG (see PAR. 2-6).
2. With front panel power circuit breaker to OFF position, connect the power supply to source
power (see PAR. 2.5.2).
3. With no load connected, set power circuit breaker to ON. Each time the unit is turned on it
beeps and an internal self-test is performed (see PAR 3.2.1). After the test has been suc-
cessfully completed, the 4-digit Voltage Display and Current Display show the last pro-
grammed voltage and current values, respectively, in Volts and Amperes.
4. Press SHIFT /LOCAL key. Verify blue LED goes on. Press V/ OVP key: Least significant
digit of Voltage Display and integral red OVP LED at the right of the display blink. Verify
blue
LED goes off.
5. Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue until
the maximum OVP value is displayed (e.g., 33.00 for 30V model).
6. Press ENTER key to accept programmed OVP value.
7. Press SHIFT /LOCAL key. Verify blue LED goes on. Press A/ OCP . Least significant digit
of Current Display and integral red OCP LED at the right of the display blink. Verify
blue
LED goes off.
8. Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue until
the maximum OCP value is displayed (e.g., 26.25 for 25 Ampere model).
9. Press ENTER key to accept programmed OCP value.
10.Press V /OVP key. Least significant digit of Voltage Display blinks.
11. Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue until
the rated output voltage value (e.g., 30.00 for 30V model) is displayed.
12.Press ENTER key to accept programmed voltage value.
13.Press A /OCP key. Least significant digit of Current Display blinks.
14.Rotate encoder to change the digits for adjustment. Turn clockwise to increase the value,
counterclockwise to decrease the value. Tap encoder to move to the next digit. Continue until
a value of several Amperes of output current is displayed.
