3.2 Basic Operation and Output Verification
This section provides an overview and examples of front panel programming,
Default Programming menu operation, and initial functional tests for the SGI
Series power supply.
The SGI Series power supply is shipped from the factory configured for front
panel (local) voltage/current/OVP control, and with the remote sense not
connected (default to internal local voltage sensing at chassis output
terminals). The remote sense leads must be connected externally by the user
to achieved performance specifications. The Analog Control connector is
supplied with a mating connector which has the remote output ON/OFF control
signals jumpered for ON (Pin-5 shorted to Pin-6) in order to allow the output to
be enabled.
WARNING!
The power-up factory default state is output enabled, and the output will
be energized with the settings of voltage and current at zero. At initial
power-on a screen is displayed with a warning that the output will be
enabled after countdown of a 10-second timer; during this state, the
output Voltage and Current are programmed to zero, the Overvoltage
Protection (OVP) is set to maximum, and the Output State is OFF. After
the 10-second timer has elapsed, the Output State is changed to ON.
3.2.1 Initial Setup
Before connecting the unit to the AC mains, ensure that the front panel
ON/OFF power switch is in the OFF position. Check the Analog Control (J1)
mating connector on the rear panel to verify that Pins 5 and 6 (Remote Output
On/Off) are shorted together. This is the default configuration installed from
the factory. This jumper allows the output of the supply to be enabled from the
front panel when the Output On/Off button is pressed.
3.2.2 Default Programming Menu
The following subsections describe operation in Constant-Voltage Mode,
Constant-Current Mode, and Overvoltage Protection (OVP) using the Default
Programming Menu for input of setpoints.
