4.5 OPERATING INSTRUCTIONS IN LOCAL MODE
These are the instructions for operating the source in local mode. Initially after
Power ON Unit work in local mode.In local mode the power supply can be controlled
through front panel potentiometers.
Also Refer to the settings of 8Way DIP Switch provided on rear panel to operate in
Local mode.
Switch No. 1 2 3 4 5 6 7 8
Position On On On On On OFF On On
Refer fig. 3.1a for connection details in local & remote interface
Normally user can vary the V SET POT to change the output voltage while working
in constant voltage mode operation. I SET POT is used to set the output current
while working in constant current mode operation.
4.5.1 SET MODE OPERATION IN LOCAL MODE
User can view the set parameters using set mode operation before
turning the output ON. To enter the SET mode, switch off the ON/OFF switch.
When SET key is pressed for the first time then SET LED turns ON and display
shows OVP value and OVP POT LED keeps on flashing. In this mode the OVP POT
can be used to change the over voltage limit. On pressing the SET key again the
display shows the set voltage and VSET POT LED keeps on flashing. In this mode
the VSET POT can be used to change the output voltage. On pressing the SET key
again the display shows the set current and ISET POT LED keeps on flashing. In this
mode the ISET POT can be used to change the output current.
Set mode operation ends after pressing SET key fourth time & displays zero if the
output on / off switch is off. At any instant, while in set mode, if output on / off switch
is pressed the display displays the output voltage & current.
