Electrical Installation
Wire Terminations
The wire terminations should proceed as follows:
CVT & POWER SUPPLY
(see Figure 7.1)
One side of the three power supply wires (120VAC HOT, 120VAC NEU, and 120VAC GND) should be attached
directly to the electrical service panel supplying power to the installation. One end of this cable is already
connected to the CVT.
The exposed end of the power cable will make the connection between the HTK CVT and the site’s electrical
panel. This connection should be made with 14AWG wire and a 15AMP breaker at the site’s electrical panel,
and terminated in a field-wiring compartment. Wiring must remain accessible
after installation
for inspection
purposes.
VENDS 1-8
(see Figure 7.2)
Vend lines 1-8 are connected to the phoenix connector at positions 1-8 respectively. They are used to signal
to the car wash controller which wash package and buy-up items have been selected.
NOTE: the signal presented to the car wash controller is normally an open, dry contact relay closure.
COMMON WIRE
(see Figure 7.2)
The Common Wire pulled to HTK from the car wash controller is connected in Position 11 (C) of the phoenix
connector on the Wash Interface.
CYCLE/INHIBIT
(see Figure 7.2)
The Cycle/Inhibit wires are used for the car wash controller to signal HTK when a car has completed its wash
and left the bay. The signal coming from the car wash controller must be able to energize the coil of a relay
on the wash interface. This means that the car wash controller must be supplying both voltage and current
when it energizes the coil.
Inside HTK, the wiring connection depends on the signal provided by the car wash controller.
The Cycle/
Inhibit wires should be connected directly to the 4 position phoenix connector, and position 1 and 2 on the
wash interface.
WASH IN SERVICE (WIS) Signal
- Optional
(see Figure 7.2)
Some wash equipment manufacturers will use this to place the pay station into an ‘Out of Service’ mode,
separate from the cycle inhibit signals. This may also be used for an operator to manually put HTK into an
‘Out of Service’ mode. This will stop HTK from processing any further transactions until the state has changed.
