Remote Sense Connections

2 - Installation

Under normal operation, the ac source senses the output voltage at the output terminals on the back of the unit. External sense terminals are available on the back of the unit that allow the output voltages to be sensed at the load, compensating for impedance losses in the load wiring. As shown in the following figure:

♦Connect the phase 1 (φ1) through phase 2 (φ) sense terminals to the side of the load that connects to the corresponding output terminal.

♦Connect the Neutral (COM) sense terminal connector to the neutral side of the load.

♦Twist and shield all signal wires to and from the sense connectors.

The sense leads are part of the ac source’s feedback path and must be kept at a low resistance in order to maintain optimal performance. Connect the sense leads carefully so that they do not become open- circuited. If the sense leads are left unconnected or become open during operation, the ac source will regulate at the output terminals, resulting in a 3% to 5% increase in output over the programmed value.

Set the ALC command to EXT (external) to enable remote sensing. The ALC command is located under the Voltage key as explained in Chapter 4. Set the ALC command to INT (internal) to disable remote sensing.

NOTE: Phase 2 and phase 3 connections are not available on 6814B/6843A units. Connector and connections are rotated 180 degrees for 6843A.
