Actuators with plastic lubricant
The types of lubricant and amounts are listed in the Table 1 or 2.
Lubricants in the drive units supplied are designed to last the entire useful life of the unit.
During the time when the drive units are in use, it is not necessary to change or monitor the amount of the lubricant.
The actuators with plastic lubricant are labelled
“Filled: solid grease”
on the power box at the side of the hand-wheel.
Note:
The Ciatim 221 lubricant is designed for the friction points of rubber bushings against metal surfaces, roller brake, the hub
of an outer cogged wheel of a planetary-gear differential (for locations of friction between the shaft and other surfaces).
Actuators with oil charge
Check the level of oil at least yearly and refill, if required. Oil change should be made after 500 operating hoursof the
actuator, but not later than after 2 years of operation. The level of oil should be as high as the filling hole. For the actuator, Grade
PP 80 motor-car gearbox oil or an equivalent oil with the same properties
(viscosity class 80 W, according to SAE/J306a)
should be used.
Maintenance
In case the actuator is operated in a dusty environment its surface should be regularly cleaned from dust in order to pre-
vent deterioration of its cooling.
Once in two years, it is recommended to lightly smear the driving wheel gearing on the output shaft and the gear
wheel of the position sensor in the control box. Use the lubricant CIATIM 201 or PM MOGUL LU 2-3.
14. FAILURES AND THEIR REMOVAL
Actuator in end position does not start, with motor buzzing
Make sure that no phase has been discontinued. If a slide valve has jammed and cannot be released even by
the handwheel the actuator should be dismantled and the jamming should be mechanically removed.
Caution!
The actuator, Type No. 52 036, has been engineered on the basis of a modified design variant of the actuator, Type No. 52
035, which has been fitted with an adapter at its output. This adapter is a single-speed gearbox with spur gears. The output shaft
of the adapter also serves as the output shaft of the actuator, Type No. 52 036. The operation of the control part is tied to the
output shaft of the driving actuator, Type No. 52 035.
When the hollow shaft in the control box rotates anticlockwise the fitting closes
(with the output shaftof the actuator, Type No.
52 036, rotating clockwise)
provided that the spindle of the fitting is fitted with left-hand threads. The direction of rotation of the
handwheel is the same for all types of actuators.
