LOCAL OPERATION (PD-A > 600W Models)
INTRODUCTION
These sections contain information on how to locally program the (PD-A <600W) Series. Upon powering up,
the power supplies is in local mode operation. All front panel keys may be used to control the power supply.
All operations performed in local mode, may also be performed in remote mode. The unit indicates remote
operation when the “RMT” enunciator is on the display.
STANDARD OPERATION
This power supply has two basic operating modes: Constant Voltage Mode (CV) and Constant Current Mode
(CC), and two control modes: Local Control Mode (default setting) and Remote Programming Mode. Both
operating modes are available regardless of which control mode is used.
GENERAL INFORMATION
1. The power supplies are able to directly accept programming values of voltage, current and over voltage.
"When a valid input is made, the unit will round off the value to the nearest multiple of the resolution".
If a non-valid input is made, the unit will display " --- OVER --- " and return to previous values.
2. The actua
l programming of voltage and current values via front panel keypad is straightforward. Simply,
press any of the functional keys and the VFD shows the current value in use. To change this value, simply
use the numeric keys to enter a value. If an error is made, press the "CLEAR" key and then reenter the
correct value. Once the final valu
e is set, press the "ENTER" key. After pressing the "ENTER" key,
the VFD module returns to the metering mode. If a user wishes to recall a setting, press the function key
pertaining to the operation.
For example, to recall a set voltage, press "VOLT" and then press "ENTER" or "CLEAR" key to return
unit to metering mode.
3. To reset any of the output parameters (i.e. VOLT, CURR, OVSET, and VSTEP) simply press the desired
function keys, enter the new value and press "ENTER".
