Carwash Interfaces

Activa Direct Wash Arming

Use Activa Direct arming to control the car wash through a direct wired connection to the Activa's I/O terminals.

Log into the Activa using the technician login. (The owner login does not have access to modify this.)
Touch the System Setups button.
Touch the Carwash Options button.
Touch the Arming tab.

Select Activa Direct as the Arming Option. This reveals four new settings to tune Activa Direct to your specific car wash interface.

The Out-Of-Service when setting defines what kind of signal from the car wash indicates that it is out of service. The choices are:

• Controller Power Off
  The Controller Power signal is also called “Control Power Input”, “fault”, or “trouble” by various car washes. Select this option if the absence of this signal from the car wash indicates that it is out of service. (This is the recommended setting.)

• Controller Power On
  As with above, but in this case an active signal from the car wash indicates that it is out of service. This is often called a “fault” signal from the car wash.

• Busy Signal Blink
  Some car washes don't have a separate fault signal, but instead generate a pattern on the wash busy (or in-use) signal of off, on, off, and stay-on in one second transitions. The signal then remains on until the fault condition clears.

• Busy Signal Blink or Power Off
  Combination option. The busy signal blink indicates a fault, while a signal must be received on the Controller Power input to indicate that the car wash is turned on.

This is the number of seconds that the Out-Of-Service condition must remain in effect before it takes effect. Some car washes have their Controller Power or fault signal twitch a bit at the beginning or end of a wash. This delay allows for this without indicating that the wash is off line every time.

Different car washes require that the arming signal be held for different periods of time. The two most common requirements by car washes are a two seconds pulse and “until the car enters the bay” (at which point, it becomes busy). Additionally, a timeout is required should the car never enter the bay.

To hold the signal until the car enters the bay, set this to 900 which is 15 minutes. (You can reach 900 either by pressing the up arrow for a while, or pressing down from 1.) The arming signal will thus be dropped after the car enters the bay or after a 15 minute timeout.

Many other possible values between 1 and 900 are available. The default is 2.

Time to wait for wash to begin

Selecting which outputs are activated when a wash package or additional service is armed is very much like any other arming system. When editing a package or additional service, the Wash Options tab displays the list of eight available Activa Direct outputs. (The last two are intended for use by the Additional Services, but that is not required.)

Presently, Output 1 must be included in every wash package if wash codes from the Site Controller are being used. Nothing needs to be wired to this output.

A typical car wash simply sets Output 1 and Output 2 to arm wash package #1 (with Output 2 being wired to the car wash), Output 1 and Output 3 to arm wash package #2 (with Output 3 wired to the car wash), and so on. However, any combination of outputs may be used for a single package.

The interface on the Site Controller is currently incomplete. It will always show the car wash as being Offline. Additionally, when setting the Wash Key Net Arming, it will show the Ryko names for the arming outputs. Simply ignore these names and all outputs above number 8, and numerically select the same arming outputs as on the Activa.

The “Wash Option” arming outputs and other signals correspond to terminals on the inside back wall of the Activa as shown in the following table:

AUTEC car wash interface

Activa Direct Settings

• Set "Out-Of-Service when" to "Busy Signal Blink or Power Off"
• Set "Time to hold Arming Signal" to "5 mins" (recommended). As little as "2 secs" will work.
  
• Set "Time to wait for wash to begin" to "5 mins"

Interface Wiring

The AUTEC PLC can only receive one output signal at a time to select a wash package. To handle combination washes on the EV-1 (combination system), a signal decoder is needed. The table below simply shows a basic wiring example.

Arming Output 2	712	Package 1 - Terminal 10
Arming Output 3	713	Package 2 - Terminal 11
Arming Output 4	714	Package 3 - Terminal 12
Arming Output 5	715	Package 4 - Terminal 33
Arming Output 6	716	Package 5 - Terminal 34

Interface Wiring

This information is preliminary. More details regarding voltage conversion and Input Common are forthcoming.

Do not make these connections directly!  The native Comet2 power levels are 120 VAC. They must be converted to 24 VDC.
