PRODUCT OVERVIEW
The Touchswitch™ is an electronic limit switch. 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 stainless steel, so that there is virtually 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.
WARNING
• Rotating machinery can cause serious injury or death
• Always lockout and tagout the machine prior to installation

INSTALLATION
The following are guidelines and suggestions for installing Touchswitches. The installer must take
responsibly that the Touchswitches are mounted in a position to be able to detect a belt misalignment
condition and or a pulley misalignment condition, whichever it may be. Typical Touchswitch™ mounting
positions are illustrated on pages 10 - 15.
The Touchswitch™ hole should be cut into the housing with a 57mm diameter hole saw (Image A),
centered on the edge of the belt. The hole should be cleaned and de-burred to avoid the Touchswitch™
puck binding and giving false misalignment alarms. You can mount the Touchswitch™ with 2 of the 4
ange holes, provided they are diagonal from one another. The enclosed ange shims can be used as a
template to properly place the ange holes. The Touchswitch™ needs to be mounted on a at surface,
preferably with the conduit entrance between the 3 to 9 o’clock position to minimize the entrance of water.
The Touchswitch™ can be mounted using one of the following three methods -
1. Drill and tap the machine casing for 6mm threaded bolts. Make sure that the bolts used to secure the
Touchswitch™ are short enough that they do not interfere with the operation of the machine.
2.
Use threaded rivet nuts for 6mm threads. The length of the rivet nut will depend on the thickness of the
machine’s casing. Make sure that the bolts used to secure the Touchswitch™ are short enough that
they do not interfere with the operation of the machine.
3. CD weld 6mmx32mm threaded welding studs to the machine casing.
When placing ange shims on Touchswitch™ make certain belt and or pulley contacts the Touchswitch™
face before it can contact any internal surface of leg or conveyor housing. It is best not to be any further
away from the pulley than 32mm to 38mm to the face of the Touchswitch™.

PAGE 8
When mounting on the head section of a leg or belt conveyor try to catch the belt and the pulley. On a
leg, mount the Touchswitch™ above the center line of the head shaft on the discharge side of the pulley
when possible. Sometimes this is not possible due to an inspection door, X-PAC or other obstruction.
In this case, the Touchswitch™ can be mounted on the top or up side of the head pulley. Try to mount
Touchswitches so they are accessible from the head section walkway. Be sure to mount Touchswitches
directly across from one another. On a conveyor head section mount the Touchswitch™ forward of the
head shaft in order to monitor for misalignment on the head pulley and belt. For typical mounting positions
on a bucket elevator, see illustrations on pages 10 - 13.
On a leg boot, mount the Touchswitch™ on the up side of the tail pulley if there are no obstructions. If
obstructions are encountered, use the down side of the pulley, but be sure to have the Touchswitches
mounted directly across from one another. Mount the Touchswitch™ above the center line of the boot
shaft at the shaft’s highest possible position (see illustration - page 13). You may not be able to catch the
leg boot pulley in all positions with a Touchswitch™. If desired, you can install additional Touchswitches™
along the travel of the boot pulley.

When mounting Touchswitches on open belt conveyors, brackets will usually need to be fabricated. These
brackets must be built rigid enough to take pressure from a misaligned belt. It is best if these can be
mounted so the Touchswitch™ can detect if the pulley and or the belt has shifted. On tail pulleys of open
belts that are take-up pulleys, it is good if the Touchswitch™ bracket can be mounted off of the bearing
mounting bolts. This will allow the Touchswitch™ to move with the pulley when belt adjustments are
made. For typical mounting positions on an open belt conveyor, see illustration - page 14.
On enclosed belt conveyor tail sections, mount Touchswitches to catch the top side of the belt on the
vertical angle just ahead of tail pulley. You will not be able to catch the tail pulley with a Touchswitch™
on an enclosed belt conveyor due to the ippers on the pulley. 4B recommends that some other device
be installed to catch the tail pulley, such as a surface mount temperature sensor (WDB70V3CAI). When
installing Touchswitches on the tail section, some tail adjustment will be sacriced. For typical mounting
positions on an enclosed belt conveyor, see illustration - page 15.
If / when connecting liquid tight conduit to Touchswitches, limit the length to local installation requirements.
However, when installed on an adjustable pulley or section be certain enough conduit is installed to allow
for pulley adjustments.

STANDARD WIRING
All wiring must be in accordance with local and national electrical codes and should be undertaken by an
experienced and qualied electrician.
If required by local installation code, use dust/liquid tight exible metal conduit with approved ttings to
protect the sensor cables. Conduit systems can channel water due to ingress and condensation directly
to sensors and sensor connections which over time will adversely affect the performance of the system.
As such, the installation of low point conduit drains is recommended for all sensors.
Mount a suitable junction box within 3m (9 ft.) of the sensor, and using a suitable conduit to protect the
cables, make the necessary wiring connections inside this junction box. A 3 meter, PVC coated cable
connected to the sensor contains the following 22 AWG wires:
PAGE 9
WARNING
• Touchswitch™ wiring is low voltage DC.
• Use shielded cable and keep separate from high voltage cable.
• Never run Touchswitch™ cables in the same conduit as 3-phase motor cables.
• Track belts and commission plant prior to installing Touchswitches.
• Fabricated brackets must be built rigid enough to take pressure from a misaligned belt.

PAGE 10
SENSOR OPERATION:
The Touchswitch™ is an electronic limit switch that reacts when pressure is applied to the sensor face.
If the pressure exceeds 3.6 kg (8 lbs.), the sensor relay goes into an alarm condition (Illustration D).
Illustration C denotes normal running conditions, with no pressure applied.
NOTE
The Touchswitch is factory pre-calibrated and no sensitivity adjustment is necessary. The sensor is
calibrated to switch to the alarm state when belt lateral force exceeds 3.6 kg (8 lbs). .
The Touchswitch contains a non-replaceable permanent 50 mA fuse and a thermal fuse set at 75° C
(167° F) .
4B recommends that the machine shuts down when the belt contacts the Touchswitch. If the machine
does not shut down and the belt is allowed to continue to rub against the face of the Touchswitch, the
hardened stainless steel sensor puck may wear and the heat generated by the friction may cause the
thermal fuse to blow. This fuse is non-replaceable and non-repairable.

TESTING & COMMISSIONING
Periodically test the sensor and the system to ensure both are operating correctly.
The Touchswitch™ has a built in test knob that allows for quick and easy operation verification without
removing the sensor from the mounting hole. The testing procedure is outlined below:
1. Observe that the green output LED on the sensor housing is on and the belt or pulley is not touching
the sensor.
2. Slowly turn the test knob clockwise by hand, until the LED goes out.
3. Check that the alarm and shutdown procedures work as expected.
a. If OK, continue to step 4.
b. If the system does not immediately shutdown as expected or alarm as required, then remove the
machine from service until the problem has been diagnosed and corrected.
4. Turn the test knob back to its original position (about 1/4 turn). Make sure that the knob is loose,
meaning not turned all the way to the left or right.
5. Observe that the LED is now on, indicating the sensor has power and is not in alarm.
As part of your ongoing maintenance program, periodically test the sensor and system, and visually
inspect the contact surface of the sensor and the sealtite, the wires, junction box and conduit.
