Introduction:
The TouchSwitch™ from 4B is an electronic limit switch with no moving parts. When a belt misaligns or a
pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force
of the belt or pulley and activates a voltage free relay contact. This relay contact is used to immediately
alarm and shutdown the machine. The face of the sensor is made from hardened and annealed stainless steel,
so that there is no wear when a belt contacts it. The sensor is not affected by dust or material build up and
will still work when completely covered by material. Sensors are normally installed in pairs on opposite
sides of the machine. Usually a pair of sensors at each pulley is used, but additional pairs can be installed as
required. An external test knob allows for quick and simple sensor / system testing.
Installation:
Warning: Always lock-out and tag-out the machine prior to installation and set-up.
Mark a location on the outside of the machines casing where the misaligned belt or pulley would contact the
center of the stainless steel sensing face. At this location drill a 55mm diameter hole through the machines
casing. With the sensor centred on this hole and the conduit entry pointing down, mark the four fixing holes
(equally spaced on 73.7mm diameter). Ensure that the rubber gasket is in place and mount the sensor using
screws, bolts or studs. (If required, use the additional plastic spacers provided to reduce the distance that the
sensor face protrudes into the casing). If the casing material allows, mounting holes can be drilled and
tapped for M5 screws, allowing sensor installation and removal from the outside. However, make sure that
the mounting screws do not protrude through the machine casing where they could come in contact with the
belt.
Earth Bonding – Please note the bare metal around one of the four mounting holes is to provide a
guaranteed earth connection to the elevators casing.
