BE3-59V

INTRODUCTION

The BE3-59V ac voltage relay provides voltage monitoring

and protection in three-phase systems. The BE3-59V

operates when the adjustable voltage trip point is reached. A

reset control is provided with an adjustment of 1 to 15% of

the nominal voltage. Reset ensures that the parameter

being measured returns to the percent set below the trip

point before the relay returns to the original state. The

output relay energizes when the input signal exceeds the

trip point. A red LED indicates the state of the output relay.

A green LED indicates the condition of the power supply.

AGENCY COMPLIANCE

The BE3-59V complies with the following:

• cULus Listed to UL 508 and CSA C22.2 No. 14

• CE compliant

• GOST-R certified per the relevant standards of

Gosstandart of Russia

OPERATION

BE3-59V ac voltage relays have two user-adjustable

controls labeled SET and RESET. The SET control adjusts

the relay trip point. When the monitored voltage exceeds the

SET control setting (adjustable from 0 to 110 Vac) the

output relay operates. The RESET control adjusts the

difference between the trip voltage and the reset voltage.

Reset occurs when voltage decreases below the RESET

setting (adjustable from 1 to 15% of the nominal voltage).

The RESET setting is set as the percentage below the trip

voltage where the relay will reset.

Setting Example: a BE3-59V relay with a nominal input

rating of 120 Vac has the following settings:

• SET - 80 Vac

• RESET - 5%

A trip occurs when the sensing voltage rises above 80 Vac.

Reset occurs when the voltage decreases below 74 Vac (80

Vac – 6 Vac or 5% of the nominal voltage).

INSTALLATION

BE3 ac voltage relays are designed for mounting on

standard DIN rails that comply to DIN-EN 50022. Mounting

involves hooking the top edge of the cutout on the base of

the case over one edge of the DIN rail. The opposite side of

the cutout containing the release clip is then pushed over

the opposite side of the DIN rail. To remove or reposition the

relay, lever the release clip and move the relay as required.

BE3 relays should be installed in a dry, vibration-free

location where the ambient temperature does not exceed

the operating temperature range. Connections to the relay

should be made using wire that meets applicable codes and

is properly sized for the application. Figure 1 shows the

connection terminals for the BE3-59V relay.

CALIBRATION

The calibration marks on the faceplate have a maximum

error of 10% and are provided only as guides. Proper

calibration requires using an accurate voltmeter in parallel

with the input signal. Use the following procedure to

calibrate your relay.

Overvoltage

1. Adjust the SET and RESET controls fully clockwise

(CW).

2. Apply the desired trip voltage to the relay.

3. Slowly (allow for the 200 ms operating time) adjust the

SET control CCW until the relay trips.

4. Reduce the applied voltage to the desired reset level.

5. Slowly adjust the RESET control CCW until the relay

resets.
