ANTI-COLLISION WIRING
The process consists of two variables in order for the Tunnel Master
Jr. to go
into an anti-collision panic. The first variable is for the Tunnel Master
Jr. to
validate a car through some sort of sensing device. The second variable is the
anti-collision start time in the wash settings on the Tunnel Master
Jr.
When a car is in the sensing device and a second car reaches the Anti-collision
Start Time, the system will go into a panic until the sensing device is cleared.
The system must also have a panic circuit wired in for this function to be
able
to restart the conveyor.
(See “Panic Stop Circuit Wiring” on page 30.)
The magnetic loop and the photo eye are two examples of anti-collision
devices that operate the open contacts that interact with the
Tunnel Master
Jr. wash controller.
(See “Anti-Collision Wiring” on page 32.)
The following diagram shows how to wire an anti-collision system into
the Tunnel Master
Jr.
!
IMPORTANT: The anti-collision on the Tunnel Master
Jr. is
a function to help prevent cars from running into each other
at the exit end of the tunnel. In order for this to work you
need an anti-collision device mounted in the tunnel at the
spot where you could have
a potential collision.
