6 Maintenance and test instructions

The person responsible for operating the motors must ensure that the prescribed maintenance work is
carried out. The following maintenance schedule is designed for use in hazardous areas (see section 2.1
Intended use).
The inspection cycles are subdivided below into the "Vertical" and "Horizontal" applications.
Mechanical maintenance work with pointed tools must be carried out outside the explosive
atmosphere.

Action
Check for bearing clearance, abrasion and ease of
movement.
The bearing must be replaced if there is clear
evidence of wear or sluggishness of the slider.
Check that the slider surface is clean and not
scratched. Scratched sliders must be replaced,
otherwise clean sliders.
Tighten the plug screw connection.
(Tightening torque 5 Nm according to section
"Electrical connection of the motor")
Check whether the cooling circuit is permanently
guaranteed.
Check whether the external bearings are still firmly
screwed onto the stator without a gap.
(Tightening torque 6 Nm according to section
"Mounting the motor")
Ensure that no thick layers of dust form on the
housing and external bearings. Large deposits
disturb the heat radiation.
Replace the plastic bearing and the wiper on both
sides (see section "Mounting the motor").
Check that the slider surface is clean and not
scratched. Scratched sliders must be replaced,
otherwise clean sliders.
Tighten the plug screw connection.
(Tightening torque 5 Nm according to section
"Electrical connection of the motor")
Check whether the cooling circuit is permanently
guaranteed.
Check whether the external bearings are still firmly
screwed onto the stator without a gap.
(Tightening torque 6 Nm according to section
"Mounting the motor")
Ensure that no thick layers of dust form on the
housing and external bearings. Large deposits
disturb the heat radiation.
If friction is noticeable during the movement of the
rotor, the motor must be switched off immediately.
Check the alignment of the load guide and the rotor.
