5. Field Wiring
See the warnings section of this document for important warnings
pertaining to the wiring of Quantum units. Remove and replace cover
before and after wiring, per instructions given in the Switch Adjustment
section above.
Required Tools: slotted screw drivers for terminal strip screws (#2), cover
screws (M4, M5, #10 or 5/16 by model), and grounding screw (#8 or M5 by
model); wire strippers as required for field wires; Allen key for M8 cover
screws (777/877).
1. Wire the AccuTrak monitor strictly according to the wiring diagram on the
inside of the enclosure cover.
2. Confirm that the ground wire is secure under the green grounding screw in
the enclosure.
3. Seal all unused conduit entries as required with suitably certified plugs
having an ingress protection rating of IP67 or better.
4. Ensure that only suitably certified cable glands are used, having an
ingress protection rating of IP67 or better.
5. Ensure that the temperature rating of all field wiring meets the service
temperature range of the application.
6. Maintenance and Repair
Maintenance or repair of Westlock equipment must only be done by Westlock
Controls or by qualified personnel that are knowledgeable about the
installation of electromechanical equipment in hazardous areas. All parts
needed for repairs or maintenance must be purchased through a Westlock
Controls authorized distributor to maintain warrantee and to ensure the safety
and compliance of the equipment.
No routine maintenance of Westlock AccuTrak units is recommended when
units are installed in environments for which they are designed. Severe
environments may warrant regular replacement of field units every two to five
years for maximum performance and safety.
Troubleshooting
Problem: No signal at the control device
 Check that power supply to the loop is functioning correctly and
adequate to power all devices on the loop;
 Check that power being supplied to switches is within the rated
specifications;
 Check wiring integrity immediately at the connection to the control
device;
 Check field wiring coming into the AccuTrak terminal strip for proper
connection and good wire preparation practices (approximately ¼” of
insulation removed and all strands intact);
 Check that field wiring is no larger than 12AWG for proper fit in
terminal strip and compliance with terminal strip rating;
 Check that wiring integrity is good between switches and terminal strip;
