9.
Install the new motor; connect it to the main board.
10.
Re-install the dome mirror/detector plate assembly and re-connect the detector to the main board.
11.
Re-connect the power supply harness and the power supply assembly to the main board.
12.
Re-connect the AC cable to the power supply.
13.
Re-install the optical bench in the bottom half of the enclosure.
14.
Re-connect the Analog and digital cable to their respective sockets on the main board.
Main Board Replacement
This operation does not require the optical bench to be removed from the sensor enclosure.
1.
Remove the top half of the sensor enclosure.
2.
Remove the four Allen screws that hold the main board to the optical bench.
3.
Gently lift up the main board and disconnect all the cable connectors from the board.
4.
Connect the various connectors to the main board and locate the new board on the top of the
optical bench.
5.
Re-install the four Allen screws.
Note: A main board replacement will require that many of the MCT setup and calibration
parameters, be re-configured to match the new boards’ operation with that of the original board.
Consult PSC for advice on this.
Detector Replacement
This operation does not require the optical bench to be removed from the sensor enclosure.
1.
Remove the top cover from the sensor.
2.
Unplug the detector from the main board.
3.
Remove the two Allen screws that hold the detector in place.
4.
Install a new detector and re-fit the Allen screws.
5.
Plug the detector to the main board.
Power Supply Replacement
This operation requires that the optical bench be removed from the bottom half of the sensor
enclosure.
1.
Unplug the analog cable from the main PCB.
2.
Unplug the digital cable from the main PCB.
3.
Locate the 6 screws that hold the optical bench into the enclosure.
4.
Remove these screws and gently lift out the optical bench. The optical bench will still be
connected to the power supply by the AC input cable. Remove this cable from the power supply.
5.
Remove the two Allen screws that hold the power supply to the main board.
6.
Disconnect the DC cable harness from the main board.
7.
Lay the power supply assembly on the bench and take out the power supply module.
