Roller Locator Wiring

IMPORTANT: You can add a roller locator to the Tunnel Master® Jr. to keep your rollers
from jamming your conveyor. In order to do this, a roller locator switch must be installed
on your conveyor to signal the presence of a roller.
When a roller locator is used, the Tunnel Master® Jr. will wait to fire a roller until the trailing edge of
the signal is detected from a roller locator. There are various devices available to detect the roller and
because the Tunnel Master® Jr. reads the trailing edge of the signal either a normally open or normally
closed switch can be used.
To set this up two things need to be done:
A roller locator switch needs to be wired into Input 9, and installed on the conveyor. This
„
switch should be positioned so that as soon as a roller passes the switch it will be in a
position where it is safe for the roller forks to come up.
Turn the roller locator function on in Wash Settings.
„
The following diagram shows how to wire the roller locator into the Relay Box.
