Shipped
Configuration
(Local Control
Mode)
The factory ships units already configured for local control (front panel) operation.
Table 3.1 summarizes this configuration.

Setting
Output
Voltage and
Current Limit
Install the power supply and connect the load as described in Section 2 . Ensure that
the power supply is set for local control as described in “Shipped Configuration
(Local Control Mode)” on page 53 . Then, set the output voltage and current limit at
the front panel with the following procedure.
1. Turn both the voltage and current controls fully counter-clockwise.
2. Turn the power ON.
3. Press the STANDBY switch to its IN position to disable the power supply
output.
4. Press and hold the V/I CHECK button to display the voltage and current control
settings on the voltmeter and ammeter displays.
5. Adjust the voltage control to the desired voltage (the compliance voltage for
applications using current mode operation).
6. Adjust the current control to the desired current limit setting.
7. Release the V/I CHECK button.
8. Press the STANDBY switch to its OUT position to apply power to the load.
Note:The control circuits have been designed to allow you to set output voltage and
current up to 5% over the model-rated maximum values. The power supply will
operate within these extended ranges, but we cannot guarantee full performance to
specification.
Local Control Configuration Additional References
Use the front panel controls to adjust the
output voltage and current limit settings. (Note:
You can use the LOCAL button only when you
have a digital programming interface installed.) Section 3 covers front panel
operation. See Section 4 for how to
set up for remote analog
programming.
The supply’s sense point is at the rear panel
output connector terminals. See
“Local and Remote Sensing”
on page 48
for how to change from
local to remote sensing.
The over voltage protection (OVP) set point is
adjusted at the front panel to approximately
110% of rated output voltage. See
“Using Over Voltage Protection
(OVP)” on page 59
for how to
change the OVP setpoint.
The over temperature shutdown function
automatically resets when activated as
determined by the position of rear panel switch
SW1-8. A latch off setting is also available. See
“Over Temperature Protection
(OTP)” on page 63
for more
information about switch SW1-8
settings for OTP recovery.
