Basler Electric BE3-27T - Manual (Page 2)

6. Adjust the DELAY and repeat Steps 4 and 5 until you have the
desired time delay.
Undervoltage
1. Adjust the SET and DELAY controls fully CCW.
2. Decrease the applied sensing voltage from the nominal value
until the desired tripping voltage is reached.
3. Slowly adjust the SET control CW until the relay trips (allow for
the 200 ms operating time).
4. Set the DELAY control to the desired time delay and apply
nominal voltage to the relay.
5. Step down the applied voltage from nominal to a level just
below the trip level set in Step 3 and measure the time delay.
6. Adjust the DELAY and repeat Steps 4 and 5 until the desired
time delay is achieved.
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.
