All the electrical equipment that might be used for maintenance or cleaning on the outside of
the electric motovibrator must be certified:
- Zone 21 for ATEX IECEX environments, C22.1 art.18 CEC.
- Class II Div.2 (NEC 500.5)

THE USE OF THE MOTOVIBRATOR IN POTENTIALLY EXPLOSIVE ATMOSPHERES VIA A PWM

INVERTER IS ALLOWED IN A FREQUENCY RANGE FROM 20Hz TO THE FREQUENCY ON THE
RATING PLATE.
FOR ETL CERTIFICATION MAY BE USED WITH PWM INVERTER ONLY AFTER ASSESSMENT OF THE
MOTORS ON THE PLANT.
MOTOVIBRATORS FROM SIZE 60 TO 110 ARE FITTED WITH A PTC 130°C THERMISTOR.
CONTROL INSTRUMENTS GUARANTEE THE MOTOVIBRATOR STOPS IF THE LIMIT
DESIGNATED
VALUES ARE REACHED AND THE INTERVENTION MUST BE "FAIL SAFE" (REDUNDANT).
THE APPLICATION OF THE THERMISTORS FOR THESE USES MUST BE STRICTLY REQUIRED AT THE
TIME OF ORDER. THE APPLICATION OF THERMISTORS BY COMPANIES NOT CREDITED BY OLI S.p.A.
RELIEVES THE MANUFACTURER FROM ANY RESPONSIBILITY.
OLI ® S.p.A. grants a 24-month warranty on the products it manufactures. The period starts from the date on the transport document. The
warranty does not apply to failures and/or defects caused by incorrect installation or use, or by incorrect maintenance or modifications
made without the authorisation of the manufacturer.
Namely, the warranty and the compliance with regulations become null and void if the electric motovibrator:
- Is tampered with or modified.
- Is used incorrectly.
- Is used by not following the limits specified in this manual and/or is subjected to excessive mechanical stress.
- Has not undergone the necessary maintenance or if it has been carried out only in part and/or not correctly or by personnel not
trained correctly
- Has suffered damage due to neglect during transport, installation and use.
- Non-original spare parts have been inserted.
Upon receipt of the product, the recipient must ensure it does not have any faults or damage due to transport and/or incompleteness of
the supply. Any defects, damage or incompleteness shall be immediately reported to the manufacturer in writing with a countersignature
of the carrier.
Products returned for repairs under the warranty must be sent FOB to our plant.
