5. Test the circuit operation.
a. Connect temporary jumper leads across
relay contacts, and primary interlock and
door sensing switches to simulate shorted
switch contacts. Locate convenient
connections in the circuit to be certain
COM and NO terminals are used.
b. Connect the ohmmeter (Rx1) across the
line terminals of the power cord. Continuity
must show:
• Door closed: low ohms
• Door open: 0 ohms
c. Remove the 20-amp fuse. The circuit must
open (infinite ohms). If the circuit does not
open, check wiring of monitor and interlock
circuits.
WARNING: After completing the test, remove the
temporary jumper leads from the interlocks and
relay, and reconnect the monitor switch leads.
