Model BE3-59T-V
INTRODUCTION
The BE3-59T-V ac voltage relay provides voltage monitoring and
protection in three-phase systems. The BE3-59T-V operates when
the adjustable voltage trip point is reached. A time delay control is
provided with an adjustment of 0 to 10 seconds (relay operating
time is typically 200 milliseconds). This time delay may be used to
prevent false tripping when there are slight variations in the voltage
supply. The output relay energizes when the input signal exceeds
the trip point for the duration of the time delay. A red LED indicates
the state of the output relay. A green LED indicates the condition of
the power supply.

OPERATION
BE3-59T-V ac voltage relays have two user-adjustable controls
labeled SET and DELAY. The SET control adjusts the relay trip
point. The DELAY control adjusts the length of time required to
operate the output relay after the trip point is exceeded. When the
monitored voltage exceeds the SET control setting (adjustable from
110 to 150 Vac), the time delay (established by the DELAY control
and adjustable from 0 to 10 seconds) begins timing down. If the
overvoltage condition persists for the duration of the time delay, the
output relay operates.
Setting Example: a BE3-59T-V relay with a nominal input rating of
130 Vac has the following settings:
• SET - 130 Vac
•
DELAY - 4 seconds
A trip occurs when the sensing voltage rises above 130 Vac and 4
seconds elapses. Reset occurs when the voltage decreases below
1% of nominal below setpoint.
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. Figures 1, 2, and 3 show the connection
terminals for the BE3-59T-V 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 control fully clockwise (CW) and the DELAY
control fully counterclockwise (CCW).
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 trip voltage from the relay and set the DELAY
control to the desired time delay.
5. Apply the trip voltage to the relay and measure the time to trip.
6. Adjust the DELAY and repeat Steps 4 and 5 until you have the
desired time delay.
MAINTENANCE
BE3 relays are solid-state devices that require no maintenance. In
the event that your relay requires repair, contact Basler Electric,
Highland, IL, USA for return authorization.
