To open the stainless-steel housing (T11 VA2.1.x.x) of RoughCam IPM2036, loosen the
eight cylinder-head hexagon screws (DIN 912/ ISO 4762) together with their spring rings
(DIN 127A) on the rear side of the cable and power supply flange (see Figure 6-3). Cau-
tion: do not touch the screw threads with your skin or clothes! On the threads, there is
LOCTITE® 243™ (chemical basis is dimethacrylate ester) applied to prevent the bolted
connection from unintentional loosening because of impacts and vibrations and to seal
them tightly. It is not permitted for the customer to open the front-side sight glass flange!
There is no need of such an action.
Figure 6-3 Opening the RoughCam IPM2036 (similar illustration)
Carefully pull out the cable and supply flange to the rear, as straight as possible. Be-
cause of negative pressure, it may be difficult to remove the flange.
Attention: The mounting adapter with the housing’s PTC heater, camera module and op-
tics, as well as the temperature control, and (if applicable) auxiliary relays and terminal
block are fixed on the cable and supply flange. Dealing with these components, too, you
have to work very carefully and precisely in order to avoid canting and damage to the in-
built components! Caution: do not touch the cylindrical fit surface with your skin or
clothes! On the surface, there is oil lubricating paste to protect the surface against fretting
corrosion and mechanical stresses.
When you open the housing, pay attention that you do not damage the GYLON® flat seal
(blue, RAL5012) and do not make it dirty! The flat gasket is loosely attached to the cable
and power supply flange. It is fixed only by the bolted connections!
