ROLLER LOCATOR WIRING
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:
24 VAC SUPPLY
(BY OTHERS)
COMMON
NORMALLY
OPEN
TREADLE SWITCH
N.O. CONTACTS

TMJ RELAY BOX TERMINAL STRIP (TOP)

Input 10 +

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.
