BE1-79A Testing

6-5

POWER HOLDUP CIRCUIT TESTING

Power holdup circuit testing applies only to BE1-79 relays with part numbers 9310200101 and
9310200201.

Part Numbers 9310200101 and 9310200201

Remove 120 Vac operating power from terminals 5 and 6. Measure the time from when the operating
power is removed until the RS contacts (terminals 9 and 10) close. The time should be 1.3 seconds or
greater.

TROUBLESHOOTING TIPS

The front panel LED indicators will annunciate certain conditions that will inhibit the BE1-79A relay from
providing reclose protection.

Blinking LEDs

This annunciation indicates low or incorrect relay input voltage. Verify proper contact sensing jumper
selection.

All LEDs On

This annunciation indicates an EEPROM error or recent cycling of relay operating power.
