Set Tunnel Controller to Auto Pulse

A Pulse signal is a vital component of washing a car with an ICS controller. If a Controller is unable to get a signal from the Pulse sensor, it will not know how fast the conveyor is moving a vehicle along the tunnel, and nothing will activate in the tunnel.
If you are experiencing an issue where the conveyor, roller, and entrance lights activate, but the roller fork is continuously in the up position when sending a roller signal, there is a setting called Auto-Pulse that can be enabled temporarily to test if the cause is the Pulse sensor or not. If this issue is caused by the sensor, turning on this setting can allow a site to operate until the root cause of the incident can be determined.
In order to enable this setting, you will need to be able to access your controllers settings. This may be on the controller itself or through a computer that is connected to the controller by serial or ethernet cable.

Tunnel Master Jr. (TMJ)

1. From the Faceplate of the TMJ, press the Menu button, then 3 for WashConfiguration, then 4 for Wash Settings.
2. Use the F2 button to scroll through the settings until we see the setting called AutoPulse. Set this to Y by using the number 0 on the faceplate keypad.
3. In order for this setting to start washing the vehicle at the correct time, you will need to use the F1 button to scroll to AutoPulsePeriod. This should already have a number defined, if it does not, you will need to calculate this using the Set Pulse Length and Auto Pulse Period document.

Tunnel Master wbc (WBC)

1. Log into the Controller and navigate to Configuration > Tunnel Settings > Pulse
2. Find the Setting named Auto-Pulse and set it to ON. You will need to click on the available white space to the side of the gate settings in order for the setting change to be finalized.
   
   
   
   
3. In order for this setting to start washing the vehicle at the correct time, you will need to set the AutoPulsePeriod. This should already have a number defined, if it does not, you will need to calculate this using the Set Pulse Length and Auto Pulse Period document.

Considerations:

You may need to make minor adjustments to the Auto Pulse Period value for optimal performance, depending on the result of test washes.

After this has been changed, the tunnel equipment will operate on an assumed travel speed for the conveyor. This is NOT a permanent fix, and should be changed back once the Pulse sensor has been repaired or replaced.

Perform a test wash with a Ghost Car before washing actual vehicles.

If you change the system to Auto-Pulse but the issue is still present, the Pulse sensor may not be the cause of this issue, due to this, other variables should be considered and investigated. Please refer to available documentation or contact ICS Support for assistance.
