4. Front-panel Operation

So far we have covered the quick start chapter which briefly introduced the front panel operation and how to check basic voltage and current functionality. This chapter describes in detail how to operate the instrument manually via the front-panel keys.

4.1 Front-panel Operation Overview

z The power supply is shipped from the factory ready for front-panel operation mode. At power-on, the power

supply will automatically enter the front-panel operation mode and the instrument can be controlled via the font panel keys and knob. The power supply enters remote mode as soon as a valid remote command is received via the communication connector in the rear. Switching to remote mode does not impact the supply’s output parameters. In remote mode, front-panel operation is disabled. If the power supply is in remote mode, and

the [LOCAL] key is not disabled, you can revert to manual mode by pressing the [LOCAL] key .

z The power supply is in Meter mode when it is powered on. In this mode, the VFD will display the actual

voltage and current output value. If the user adjusts the knob while in this mode, the power supply will automatically enter Set mode then revert back to meter mode and display the modified voltage and current values.

z The output of the power supply can be enabled/disabled from the front panel by pressing the z The VFD also displays operation states or error information. “ ”means the power supply is in remote

mode. If an error occurred, ”?” will be displayed.

z If the power supply is in Set mode, you can modify parameters using the knob. If the power supply is in

menu operation, the knob is used for menu selection. If the power supply is in the regular output mode you can use the knob to set the voltage value.

DB9 Interface Details

The DB9 connector in the rear panel of the power supply provides a TTL level signal .It can be connected to a standard PC interface via the IT-E131 or IT-E132 isolated communication cable.

Note: Setting of the address is optional. It is not required to communicate with the instrument. The address can be set from the front panel and is stored in non volatile memory. This feature is useful when connecting several instruments, e.g. via USB hub. In this scenario, Windows assigns a virtual COM port to each device which is unknown prior to establishing communications with the instrument (could be different each time). In this case, the address will allow the user to correlate each virtual COM port with the address assigned to each instrument.
