USE
- The VIGIBELT®TOUCH is a lateral displacement detector that prevents the offset of elevator straps or conveyor
belts, and or incidentally the elevator pulley offset. It reacts to the pressure of the strap or strip, which comes into
contact with the front face of the detector. The detectors are normally installed face to face in pairs preferably on the
rising leg near the pulleys for the lifts, and on the stretched strand side near the drums for the conveyors.
The detectors can be directly connected to a programmable logic controller, or for total safety to an independent
central unit "monitoring M-JET". The electrical circuit can thus control an alarm or a machine stop.
For elevators taller than 20 meters, we advise to equip the head with a second kit VIGIBELT®always on the rising
sheath side.
The sensors are triggered when the strap exerts a load of about 5 daN.
description
- The VIGIBELT®TOUCH kit is composed of two detectors, four elastomeric wedges of 3mm (NBR), and the fixing
screws (M6).

PRECAUTIONS
The VIGIBELT®TOUCH kit must be installed, connected and put into service only by competent personnel. The
personnel need to have electrical accreditation, a knowledge of the regulation and the disposition concerning
the installation of those device, especially for Ex II3D version integrated in ATEX zones.
- Carry out beforehand an electrical connection study to install the VIGIBELT® TOUCH (standardized electrical
diagram, power supply and electrical protection, plc control, ATEX zones).
- Check that the temperature range of use of the VIGIBELT®TOUCH (variable according to version) corresponding
at application.
- Check during the first commissioning of the bucket elevator in the handling phase, that there is no sealing defect
(dust leak) between the sheath of the elevator and the VIGIBELT®TOUCH.
- Shut down the bucket elevator or belt conveyor to a standstill (off) before any installation or intervention on the
VIGIBELT®TOUCH (intervention information to be indicated on the machine).

installation
1) Make two symmetrical round openings (opening Ø56mm + 4 holes Ø7 on Ø72) on each side on the riser of the
elevator: figure-A
Figure A
On a bucket lift, position the VIGIBELT®TOUCH
detectors on the rising leg side close to the axis of the
pulleys and the strap.
On a belt conveyor, position the VIGIBELT®
TOUCH detectors side stretched strand close to the
axis of the drums and the strip.
Make an opening of
Ø56 in the axis of the
strap

2) Assemble the M6 pan screws with the low nuts on the sheath (clamping torque 6 N.m): figure-B.
3) Adjust the trigger distance of the VIGIBELT®TOUCH detectors. This distance corresponds to the dimension
between the inner wall of the elevator and the contact face of the detector.
For this, you have the possibility to make three figure-C detection settings:
No. 1 - Detector without additional wedge, thickness elevator (example 3mm), i.e. a distance of 20mm
No. 2 - Detector with an additional wedge, thickness elevator (example 3mm), i.e. a distance of 17mm
No. 3 - Detector with two additional wedges, thickness elevator (example 3mm), i.e. a distance of 14mm

4) Position the VIGIBELT® TOUCH detectors on the openings and screw the M6 brake nuts with the washers
(clamping torque 4 N.m) according to Figure-D.
5) Connect the VIGIBELT®TOUCH according to the electrical scheme E or F:
NC detector = positive safety, permanent control of the proper functioning of the sensor
Signal loss indicates that there is a strap offset problem

6) After completing the mechanical and electrical installation of the VIGIBELT®TOUCH, you must proceed to the
verification of each detector to ensure that they are all operational. For this, you need to trigger each VIGIBELT®
TOUCH by pressing their contact face. This simulation makes it possible to validate that the fault information is
communicated to the control system (M-JET monitoring, control plc, ...).
CONTROL & PERIODIC MAINTENANCE
1) To ensure the functional integrity of VIGIBELT®TOUCH, you must schedule periodic inspections. The frequency
of inspections must be sufficient to avoid dangerous situations (situations that affect the intrinsic functioning of the
VIGIBELT®TOUCH).
2) During these inspections, check that the VIGIBELT®TOUCH are not affected by the following defects: dust layer
>2mm, dust leak between the sheath of the elevator and the VIGIBELT®TOUCH, non-operational power supply
voltage, degraded electrical wiring, shocks on the envelope of the VIGIBELT®TOUCH, triggering of the detector with
a charge > 5 daN, etc...
3) In the case of one or more defects found, you must proceed with the restoration in order to correct the defect(s)
before you can use the bucket lift or belt conveyor again.
4) Only personnel trained and authorized in maintenance procedures for these equipment are able to carry out
inspections for VIGIBELT®TOUCH.
DISPOSAL
When dismantling the VIGIBELT®TOUCH, the user must ensure the proper disposal of this device and hand over
to the specialized harvesting centers the components according to their nature (stainless steel, electrical
equipment, seal, etc.).
In the event that the VIGIBELT®TOUCH kit is used, controlled, under conditions contrary to the precautions
described in this instruction manual, STIF declines all responsibility for damage caused to man, animal,
environment, material property.
