1.2 Electrical
1.2.1 Power Requirements
C-Start requires 120 VAC, 8 Amps service with a dedicated circuit breaker.

Note: Ensure the protective earth ground wires do not carry any motor return current. Only
the neutral wire should carry return current. Follow local electrical code when wiring
the C-Start.
1.2.2 Conduit Requirements
At a minimum, (3) conduit runs are typically required:
• Power – Conduit run from C-Start to AC Power Service Panel
• Control – Conduit run from C-Start to the Car Wash Controller
• Data – Conduit run to the network router location within the facility. This
conduit may also house Intercom control wires and telephone lines (for dial
credit applications.
Conduit size should be at least ¾ in. Refer to local and national electrical codes to
select the proper conduit type and size. Conduit stubs should be installed to enter the
C-Start base through the oblong conduit opening as shown in Figure 2 and extend at
least 3” above the concrete surface.

2.3 Base Installation

Note: Pull all wires through conduits before mounting the base. See Electrical Planning for
wiring requirements.
The C-Start bases are available in (2) heights as shown in the illustration below. This
document describes the procedure for installing the straight base. Angled bases are
also available and they are supplied with a manual addendum (MN1001), which
provides additional instructions.
Figure 3. Straight Bases Dimensions
1. Position the base in place and mark the locations of the (4) mounting holes on
the concrete surface. Remove the base and drill (4) ½” diameter holes, 2” to
2 ½” deep in the marked locations.
2. Insert the anchor bolts (supplied with the base) in these holes and carefully
drive them into place with a hammer. When the anchor bolts have been set,
tighten the nut to secure the bolts in the concrete. Remove the nuts from the
anchor bolts
3. Place the base on the anchor bolts, while ensuring the wires pulled
through the conduit are not pinched under the base. Pull the wires
through the top opening of the base and ensure there is at least 48 inches
of wire draped over the top edge of the base.
4. Place the level on top of the base, and verify its level in both directions
(front to back and side to side). Use shims as needed to level the base.
Once the base is level, place the nuts on the anchor bolts and secure the

3.2 Connecting Power
1. Route the main power wires to the AC terminal strip on C-Start’s power panel
(as shown below) and trim the wire to remove excess. Strip the insulation
approximately ¼ ” on each conductor.
2. Remove the plastic shield on the power terminal block and loosen the 3
screws where the wires are to be connected. Install the Neutral (White),
Ground (Green), and Line (Black) wires under the screw clamps in the correct
positions (as shown below) and re-tighten the screws to hold the wires in
place.
3. Use wire ties to route and secure any extra cable. Replace the plastic shield.

3.3 Wash Control Wiring
3.3.1 Overview
In applications where the C-Start will communicate with the Wash Controller, the
wash control wires will need to be connected to the Wash I/O Board. This board is
located on the right wall of the enclosure and is shown in the picture below. The
board is supplied with screw terminal plugs (not shown) installed in the green
connectors to accommodate field wiring. You will need a thin tipped, flat head
screwdriver to open and tighten the screw terminals.
Figure 6. Wash I/O Board Connector Pinouts
Most wash manufacturers use a five-wire system to provide the arming signals for the
selected wash packages. One common line and four arming input wires are fed from
the wash’s PLC to the Wash I/O board. In addition to these five wires, a Wash-In-
Use (WIU) Hot and WIU Neutral are required to reset the wash electronics. Typically,
these are also provided by the PLC.
Each wash manufacturer has its own specific color code system and wash relay pin-
outs; therefore, it is important to review the appropriate wash documentation prior to
beginning this portion of the installation.

3.3.2 Wiring the Wash Relay Interface
To wire the wash relays, remove the screw terminal plug from the J17 connector and
install the wires from the PLC to the appropriate pin numbers per the table below.
Replace the plug in J17 when finished.

respectively)
Pin 9 Wash Relay Common
Pin 10 N/A
3.3.3 Wiring the Wash-In-Use Interface
Wash equipment requires a reset circuit. This circuit is generally identified as the
“Wash-In-Use” (WIU) signal. It is not uncommon for values of this voltage to be as
much as 115-120 VAC, so it is extremely important to verify that there is no power
applied to any of the wash components before proceeding.
To wire the wash in use and fault inputs, remove the screw terminal plug from the J18
connector and install the wires from the PLC to the appropriate pin numbers per the
table below. Replace the plug in J18 when finished.

Pin 6 Wash-Complete-Neutral
3.4 Network Cable Connection
The Cat 5 cable will need to be terminated at each end with an RJ-45 modular plug.
This termination should be performed by a technician who is experienced in
assembling network cables, because a slight misalignment in the wire termination can
cause communications problems. For reference, Appendix B provides guidelines for
terminating a network cable with a modular RJ-45 plug.
The Network (Ethernet) connection is located at the bottom edge of the processor
assembly on the left-side wall. There should be a surge suppressor installed in the
Ethernet port. Insert the terminated CAT 5 cable into the other end of the surge
protector. The facility end of the Cat-5 cable connects to one of the LAN ports on the
Unitec router. Refer to 0for details on connecting devices to the router.
3.5 Intercom Systems
3.5.1 Overview
The use of an intercom system allows two-way communications between customers
at the C-Start and staff elsewhere on site. A customer activates the C-Start’s
intercom output by pressing the help button. Without an intercom, the intercom
output can be used to activate a bell, light or other device to alert an attendant that
help is needed.
The intercom wires connect to the Display IO board on the back of the main door.
Jumpers and adjustments to control its operation are also located on that board. 2, 3,
and 4 wire intercoms are supported. A digital intercom is recommended if the

C-START
Document Number: CST1001 12
Document Name: C-Start Installation Manual
intercom wiring is sharing conduit with other communications wiring, but not required.
Unitec does not supply intercom systems.
3.5.2 Intercom Connections
The Intercom has two connectors which control the way in which the intercom is
wired and the mode of operation. J17 is the interface and connects to the customer’s
intercom unit. J23 is used to select mode of operation (two, three, or four wire
intercom systems). Twisted pair / fully shielded cable is recommended for optimum
performance.
3.5.3 Intercom Adjustments
The Intercom system has the ability to sense when voice band audio signals are
present. This allows the speakers in the unit to revert to a passive intercom mode.
This bypasses the internal audio section and allows the left speaker to be used as
an intercom.
3.5.4 Connection Overview
Call Function: The unit will initiate a call function by closing the contacts on RL5. By
default, J17-Pin 1 (H1) and J17-Pin 2 (H2) will always reflect the contact closure of
RL5. This is the default for the four-wire mode when both the call function and audio
are completely separated. More detailed instructions on this follow.
Audio: When the C-Start intercom mode is active, the audio section is floating and is
not relative to ground. By default, J17-Pin 3 (SP+) and J17-Pin 4 (SP-) will always be
connected to the audio section.
Four Wire Intercom Configuration: Two separate pairs (four wires) are used for
both the call function and audio in the four-wire configuration. In this mode, J23
receives no jumpers.
3 Wire Intercom Configuration: This mode requires two conductors for audio and
one additional conductor for the call function. This mode uses a common ground for
both audio and the call function (SP-). Jumper pins 3&4 (bottom 2 pins) of J23 and
connect H1, SP+ and SP- .
2 Wire Intercom Configuration: This type of intercom system has both the Call
Function and audio sharing the two conductors. Jumper pins 3&4 (bottom 2 pins) and
1&2 (top 2 pins) of J23 and connect the two conductors to SP+ & SP-.

C-Start functions are operational. This test should verify:
• Functionality of hardware devices (through diagnostic tests in maintenance
mode).
• Washes and added services are properly configured and wash outputs are
properly wired.
• The wash fault (Out of Service) signal places the C-Start out of service.
• C-Start Ethernet communications (through the Cat 5 cable).
• Credit card processing (Note: The merchant should confirm credit card
revenues are being properly deposited to their account).
