TESTING BE1-64F OPERATION
To test BE1-64F operation, perform the following procedures.
Test Setup
Prepare the relay for testing by making the connections shown in Figure 5-1. Set switches S1 and S2 in
the positions indicated by Figure 5-1.
Power-Up
1. Prior to applying relay operating power, verify that the Power Fail output contacts at terminals A8 and
A9 are closed.
2. Apply 120 Vac operating power to terminals A11 and A12. The Power Fail output contacts should
open.
3. Press the Target Reset pushbutton. All front panel indicators should be off except for the green
Power Status LED. The Pre-Alarm output contacts at terminals A4 and A5 and the Ground Trip output
contacts at terminals A6 and A7 should be open.
Trip/Test Pushbuttons
BE1-64F relays with part number 9367200104 are not equipped with the Trip/Test function and push-
buttons. The following steps do not apply to relays with this part number.
1. Press and hold both front panel Trip/Test pushbuttons. The Pre-Alarm output contacts (terminals A4
and A5) and Ground Trip output contacts (terminals A6 and A7) should close, the front panel Alarm
Output and Trip Output LEDs should light, and the Trip Target LED should latch on.
2. Release the Trip/Test pushbuttons. The Pre-Alarm output contacts and Ground Trip output contacts
should open and the Alarm Output and Trip Output LEDs should turn off. The latching Trip Target
LED should remain on.
Target Retention
1. Perform steps 1 and 2 of Trip/Test Pushbuttons so that the Trip Target LED is latched on.
2. Remove operating power from the relay. Wait several seconds and then apply relay operating power.
Verify that target status is retained by observing that the Trip Target LED lights when relay operating
power is restored.
3. Reset the Trip Target LED by pressing the Target Reset pushbutton.
Pre-Alarm
1. Place switch S1 in the Pre-Alarm position so that the 16 k
Ω resistor is connected between relay
terminals A1 and A3. The Pre-Alarm output contacts should close and the front panel Alarm Output
LED should light.
2. Return switch S1 to the position shown in Figure 5-1. The Pre-Alarm output contacts should open and
the Alarm Output LED should turn off.
Ground Trip
1. Place switch S1 in the Ground Alarm position so that the 4 k
Ω resistor is connected between
terminals A1 and A3. The Ground Trip output contacts should close, the Trip Output LED should light,
and the Trip Target LED should latch on.
2. Return switch S1 to the position shown in Figure 5-1. The Ground Trip output contacts should open
and the Trip Output LED should turn off. The Trip Target LED will remain lit until the Target Reset
pushbutton is pressed.
