d. BENCH TEST
NOTE
Ground refers to case of relay box.
1. Apply a + 24-volt power source to center contact of power lead receptacle (2), with negative terminal to
ground.
NOTE
When performing steps 2 and 4, a resistive load of 150 amperes will be connected
between pin B and ground and between pin C and ground respectively, and
energized for 15 seconds each load.
2. Reading at pin A of control lead receptacle (7)
should be +24v.
3. Disconnect +24-volt power source from center
contact of power lead receptacle (2).
4. Apply a +24-volt power source to pin B control
lead receptacle (7).
(a)
Reading at pin B of actuator lead receptacle
(26) should be + 24v.
(b)
Reading at pin A of actuator lead receptacle
(26) should be + 24v.

Reading at pin D of actuator lead receptacle
(26) should show ground.
5. Disconnect + 24-volt power source from pin B of
control lead receptacle (7).
6. Apply a + 24-volt power source to pin C of control lead receptacle (7).
(a) Reading at pin C of actuator lead receptacle (26) should be at + 24v.
(b) Reading at pin D of actuator lead receptacle (26) should show + 24v.
7. Disconnect + 24-volt power source from pin C of control lead receptacle (7).
8. Pin A of actuator lead receptacle (26) should show ground.
9. Check for continuity from pin E on control lead receptacle (7) to pin E on actuator lead receptacle (26).
10. Check continuity from pin F on control lead receptacle (7) to pin F on actuator lead receptacle (26).
