SQ256 Retraction Device
The probe can be traversed using a compressed air motor. Insertion and retraction are possible by interchanging
the compressed air feed on the motor.
The retraction device must be aligned such that the probe is in the correct position in the kiln or cyclone in the
inserted state.
The centre of the probe must be positioned about 5-10mm above the centre of the probe inlet. The height can be
adjusted by washers on the probe or by shims on the support.
Then weld the connecting piece with the outer casing of the kiln or cyclone. Seal the pipe inside the kiln or cyclone
with special cement. Permanently fix the traverse rail at the front and back.

Nocke = cam, T-Stück = T-piece Rohr = pipe Einzelheit = Detail
Fit the supplied solenoid valve after a compressed air shut-off valve fitted by the customer and connect to the
kiln connection pipe with the supplied compressed air hose using the screwed glands from the quick release
couplings.
Note:
The solenoid valve must not be subjected to severe effects of heat.
Fit the local control panel such that the probe traverse and cooling equipment can be observed. When present,
the traverse sounder and warning light should be fitted such that they can be easily seen to bring attention to the
traversing.
Danger: No unauthorized personnel should be positioned in the immediate vicinity of the probe, kiln
connecting pipe and the retraction device during automatic or manual traversing.
After the installation of the valve combination on the retraction device (see operating manual), the ready-made
cables from the limit switches and the three-phase motor should be connected to it with the plugs. If the terminal
box on the three-phase motor is opened, special attention should be given to ensure proper sealing and the
mating points should be regreased. The gland plugs should be screwed into the unused cable entry holes.
Be sure to fit unused cable entries on the limit switches with plug-caps.
The connections from the compressed air limit switch to the compressed air motor must be joined using the
supplied compressed air hoses according to the labelling (see also the general operating manual). No sealing
tape or similar material is needed due to the self-sealing conical joints on the hoses. Ensure absolute sealing
tightness.
