ProKiln GAC400 PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A
Probe retractor
The probe retractor moves the probe, which can be up to 3500 mm long. The movement is carried out by an electrical chain drive. The
retractor is emergency-supported by uninterruptible power supply (UPS). It is recommended that the UPS is provided from the site
according to local regulations.

Retraction in the event of malfunction
The probe is automatically retracted if any of the following malfunctions occur:
• Cooling water temperature too high
• Cooling water flow rate too low
• Cooling water differential temperature too high
• Circulation pump failure
• UPS Power supply interrupted
• Water tank level alarm
• Water tank temperature too high
Function
• Halts all probe movements
• Halts all probe cleaning by air
• Pneumatic components for blow-back of filter
• Electric connections, distributed I/O, power studs, manual operation buttons in/out probe
Ensures movement and position of the probe retractor.
Guides pneumatic lines, electrical cables, heated sample gas line and cooling water tubes.
Air blasters for cleaning probe tip, filter blowback and filter periphery
Transports the sample gas from the probe to the external gas analysis system downstream. Heating
function prevents condensation from building up.
Connection point for heated hose leading to external gas analysis system. Heating function prevents
condensation from building up.
Connection point for compressed-air supply for air blasters and for connections to the water-
cooling panel
Transport tracks for the probe buggy
Closes the kiln duct opening when the probe is retracted.
Adjustment of tension on the chain drive
• Ensemble of legs to install retractor to the floor.
• Note: the probe and retractor system is supplied with two temporary legs which are not
designed for permanent mounting.
