BE1-79A Testing

6-1

SECTION 6 • TESTING

Introduction

You may prefer to test your relay before installation. To test BE1-79A relay functionality, perform the

procedures in the following paragraphs. Figure 6-1 illustrates the necessary connections for testing relays

configured for ACR11A style operation. The connections diagram for testing relays configured for

ACR11B operation is provided in Figure 6-2.

NOTE

The following test procedures specify 120 Vac for relay power and the contact

sensing inputs. Therefore, contact sensing jumpers P3, P4, P5, and P6 must

be set in position 1 or position 2. The contact sensing circuitry will not function

with 120 Vac applied and the contact-sensing jumpers setting position 3.

Instantaneous Reclose Testing

ACR11A Style

Place Relay Style Configuration switches S1, S2, and S3 in the A position. Place Instantaneous Reclose

Jumper switch S4 in the EXT position. Place RS Contact switch S5 in the NO position.

ACR11B Style

Place Relay Style Configuration switches S1, S2, and S3 in the B position. Place Instantaneous Reclose

Jumper switch S4 in the INT position. Place RS Contact switch S5 in the NO position.

ACR11A and ACR11B Styles

1. Place Test switch S1 in the 52a position and apply 120 Vac to the relay and test circuit.
2. Connect a PC with a serial port and suitable communication software to the relay serial port. Transmit

the settings of Table 6-1 to the relay.
