STIF VIGIBELT TOUCH ATEX (II 2 D) User manual

INSTRUCTION MANUAL VIGIBELT®TOUCH ATEX (II 2 D) GB –1/4

FUNCTION
- The VIGIBELT®TOUCH is a lateral movement sensor that detects run-out of elevator belts or conveyor belts, and
at the same time the run-out of the lift pulley. It reacts to the pressure of the belt coming into contact with the front
face of the sensor. Baffle plates are usually fitted opposite each other, preferably on the upward leg close to the
pulleys for elevators, and on the load bearing side close to the drums for conveyors.
The sensors can be connected directly to a PLC, or for absolutely safety, to an independent "monitoring M-JET”
central unit. The electrical circuit can control an alarm or a machine shut down.
- For elevators more than 20 meters long, we recommend fitting the head with a second VIGIBELT®TOUCH kit, still
on the upward leg.
- The sensors trigger when the belt applies a force of approximately 5 daN.
DESCRIPTION
- The VIGIBELT®TOUCH kit comprises two sensors, four elastomer spacers (3mm NBR) and the fastenings (M6).

PRECAUTIONS
The VIGIBELT®TOUCH must be installed, connected and put into service by competent personnel. The personnel
should be qualified electricians and know the regulations and requirements concerning the installation of these
appliances, especially when installed in ATEX areas.
- Carry out a study prior to the electrical connection of the VIGIBELT®TOUCH sensors (standardised electrical
diagram, PLC control, electricity supply and protection).
- Define the sensing distance between the belt and the elevator shaft (confirmation of the triggering distance by the
person in charge of the site).
- Before any installation or intervention on the VIGIBELT®TOUCH, it is essential to make sure that the bucket
elevator is shut down (intervention warning to be posted on the machine).
- When the VIGIBELT®TOUCH is dismantled, the user should ensure that the appliance is scrapped properly and
that the components are passed to the appropriate specialist collection centres according to their nature (stainless
steel, electrical equipment, seals, etc.).

INSTALLATION
1) Make two symmetrical round openings on each side of the up shaft of an elevator (56mm dia. + 4 7mm dia. holes
on a PCD of 72mm): DIagram-A
Diagram A
On a conveyor belt position the VIGIBELT®
TOUCH sensors on the load carrying side close to
the axis of the drum and the belt.
On a bucket elevator position the VIGIBELT® TOUCH
sensors on the upward leg close to the axis of the
pulleys and the belt.

2) Fit the M6 pan head screws with the low nuts on the shaft (torque 6 N.m): Biagram-B.
3) Adjust the triggering distance of the VIGIBELT®TOUCH sensors. This distance is the dimension between the
inside face of the elevator and the contact face of the sensor.
To achieve this, three detection adjustments are possible, diagram-C:
No 1 - Sensor with no additional spacer, elevator thickness (e.g.: 3mm), i.e. a distance of 20mm
No 2 - Sensor with one additional spacer, elevator thickness (e.g.: 3mm), i.e. a distance of 17mm
No 3 - Sensor with two additional spacers, elevator thickness (e.g.: 3mm), i.e. a distance of 14mm

4) Position the VIGIBELT®TOUCH sensors on the openings and tighten the M6 locknuts (torque 4 N.m) according
to Diagram-D.
5) Connect the VIGIBELT®TOUCH sensors according to the electrical diagrams:
NC sensor = positive safety, continuous sensor function monitoring

6) After completing the mechanical and electrical installation of the VIGIBELT®TOUCH sensors, you should check
each sensor to make sure that they are all working. To do this, trigger each sensor by pressing its contact face.
This simulation serves to confirm that the fault information is transmitted to the monitoring system (monitoring M-
JET, supervisor PLC).
