Replacing The Ignitor Assembly; Closing The Detector - ABB PGC2000 Operation And Service Manual

9. Spread or expand the end of approved heat shrink to allow easy installation over the solder
connection.
10. Install heat shrink over each wire and slide it as far as possible from the connection. This will
prevent premature shrinking when the connection is soldered.
11. Overlap and solder the "tinned" ends of the green wire from the wiring harness and the green
polarizer assembly wire using approved high temperature solder and 40 watt soldering iron.
12. Apply a short wrap of glass tape over the connection.
13. Slide the heat shrink over the taped connection and shrink it with a heat gun.
14. Close the detector as described in "Closing the Detector."

Replacing the Ignitor Assembly

1. After accessing the detector elements as described in "Accessing the Polarizer and Ignitor
Elements," locate the ignitor identified by the element with the two white wires.
2. If applicable, remove any cable ties and free the wiring to expose the wire splices.
3. Cut and remove the heat shrink and glass tape from the two white wires to expose the soldered
connections.
4. Using a 40 watt soldering iron, disconnect the wiring splice.
5. Using a 3/8-inch open-end wrench, continue loosening and carefully remove the Ignitor assembly.
Note its location for reassembly.
6. Carefully insert the replacement ignitor into the detector body and finger tighten, taking care not
to damage it. Finish tightening using a 3/8-inch open-end wrench.
7. Roll each end of the two white wires of the new ignitor between your forefinger and thumb,
causing the wire ends to be tightly spiral wrapped.
8. Using the 40 watt soldering iron and approved high temperature solder, "tin" the wire ends.
9. Spread or expand the end of approved heat shrink to allow easy installation over the solder
connection.
10. Overlap and solder the "tinned" ends of one white wire from the wiring harness and one white
ignitor assembly wire and solder the wires together using approved high temperature solder and
40 watt soldering iron.
11. Repeat this operation for the remaining white wire.
12. Apply a short wrap of glass tape over each connection.
13. Slide the heat shrink over the taped connection and shrink it with a heat gun.
14. Close the detector as described in "Closing the Detector."

Closing the Detector

1. Verify that all work inside the detector housing is complete.
