Isolated Remote Analog Interface Operation

DLM 600W Series

2.1.1INTFC SETUP Switch Functions

The following sections describe the functions of the various switch positions:

V, 10V or 4-20mA Select: Position-1, when ON, selects 0-10VDC programming of the output voltage. Also, must be set to ON position when the ISOLATED ANALOG INTERFACE connector is wired for 4-20mA output voltage programming. When OFF, selects 0-5VDC programming of the output voltage.

I, 10V or 4-20mA Select: Position-2, when ON, selects 0-10VDC programming of the output current. Also, must be set to ON position when the ISOLATED ANALOG INTERFACE connector is wired for 4-20mA output current programming. When OFF, selects 0-5VDC programming of the output current.

OVP, 10V Select: Position-3, when ON, selects 0-10VDC programming of OVP threshold. When OFF, selects 0-5VDC programming of OVP threshold.

VMON, 10V Select: Position-4, when ON, selects 0-10VDC range for readback of output voltage. When OFF, selects 0-5VDC readback of output voltage. Also, must be set to OFF position when the ISOLATED ANALOG INTERFACE connector is wired for 4-20mA output voltage readback.

IMON, 10V Select: Position-5, when ON, selects 0-10VDC range for readback of output current. When OFF, selects 0-5VDC readback of output current. Also, must be set to OFF position when the ISOLATED ANALOG INTERFACE connector is wired for

4-20mA output current readback.

EXT-OFF,Active-Low Select: Position-6, when ON, selects the ACTIVE-LOW logic level for disabling the output with the EXTERNAL-OFF signal of the ISOLATED ANALOG INTERFACE connector. When OFF, selects the ACTIVE-HIGH logic level for disabling the output with the EXTERNAL-OFF signal of the Isolated Analog Interface connector.

LCK-OUT:Position-7, when ON, disables the front panel controls; the front panel LOCAL(REMOTE) switch will not toggle between the front panel and remote control.

Position-8: Not used

2.2SETUP Switch

Only two positions of the SETUP switch remain functional: Position-1, REM SNS, for remote sensing selection; Position-2, SLAVE, for master/slave selection. Their operation is the same as presented in the Operation Manual. The other switch positions, Position-3 through Position-8, are not used.
