360-t HMI Control Panel:
Important Wiring Instructions for all equipment
1.
If the electrical service is a Delta (also known as a High-Leg) system, refer to schematics before wiring
the Accutrac 360 Control Panel.
2.
Refer to the installation manual, equipment/electrical schedule and the schematics.
3.
Wire the equipment according to NEC as well as state and local codes.
4.
Insure proper grounding of control panel as well as proper grounding/bonding of the incoming
electrical service.
5.
Always run low-voltage control wires in separate conduits away from power wires.
6.
Never drill holes or run wiring into top of electrical enclosures. Use bottom entry or lowest possible
entry point on side of enclosure. Top entry will void the warranty
7.
For Accutrac 360s, run the two 25-conductor umbilical cables from the control panel to bay equipment
in separate 1-
1/4” conduits
. Whenever possible, especially on long parallel runs, keep the lines at
least 12” away from each other. Follow instructions in the Appendix for stripping insulation from the
25-conductor cables.
Locate the Control Panel as close to the bay equipment as possible. Mount the panel to the wall at a
height that the Touch-Screen is readily accessible. Route the two multi-conductor cables from the bay
equipment to the panel through separate 1-
1/4” diameter or larger conduits. On long runs it is
recommended th
at the electrician install two separates 12” square junction boxes near the wash bay
and route the 25- conductor cables through the boxes. In the future when the moving part of the
control cable needs replaced it can be spiced at the junction box rather than replacing the entire run.
Refer to the Schematics for the Power & Control wiring requirements. Please note that the Computer
Control also requires a Cat-
5 Ethernet connection to the customer’s
LAN (Local Area Network).
Locate and land the following external inputs into the Input Isolation relays. Factory supplied Input relay
coils are 24VAC/DC. 120VAC coils are available upon request.
-Input #1022
: Conveyor Pulse Signal (verify signal is received at consistent intervals)
-Input #1023
:
Conveyor Entrance/Gate Photo Eye Signal (“On” when blocked by vehicle)
-Input #1024
: Conveyor Running Signal (“On” whenever conveyor is running)
Note: Inputs #1022 & #1023 either need to be wired directly from each device or from a buffer relay
fired directly by the devices
. Do not use tunnel controller “Mirror” outputs as
this will result in
unreliable input timing and would cause the 360-t to malfunction.
