Electrical Installation Of The Temperature Compensation Set - Fluke TIP900 Operating Instructions Manual

To get a stable temperature reading of an average wallboard temperature, it's recommended to install
the opposing telescope arm pair at the center deck close to the kiln exit at the outfeed section, just past
the dryer-speed rollers. This position is where the boards are starting to pull a gap. The boards roll end-
to-end on the dryer driven rolls but the outfeed section rolls are faster, so they pull a gap between the
boards. This is necessary for the Temperature Compensation sensor, because a gap is needed in order
to differentiate between boards and the background target.

Install the IR-Sensor telescope arm as close to dryer exit or last dryer driven roll as possible.
There should be at least about 6" (152.4mm) board gap pulled at that point.

Mount the IR-Sensor telescope arm and the opposing target (black counter paddle) telescope
arm at a deck near the vertical center of the dryer. The opposite target (black counter paddle)
telescope arm needs to be mounted immediately below on the next deck, whereas the center
of the black surface should be aligned opposite to the overhead IR-sensor head.

The IR-Sensor and target telescope arms can be mounted on either side of the Outfeed
Conveyor, wherever the optimized installation position and passing wallboard coverage
prevails.

Adjust both telescoping arm sections (IR-Sensor and target) so, that the viewed spot of the
passing wallboards is about centered between the boards outer edges. Final adjustment has to
be made after initial operation of the system.

It's recommended to install an air-purge supply to have an unadulterated temperature reading
of the IR-Sensor. For that purpose please supply an air-purge with airflow of about 30 to 60l/min.
The maximum air-pressure supply shall not exceed pressures values over 5 bar (72,5psi).

Mount the IR-Sensor connection box at a convenient position with the lowest environmental
influence (temperature, humidity, EMC) up to distance where the supplied sensor cable
reaches.

4.4.2 Electrical Installation of the Temperature Compensation set

The external wiring to the Temperature Compensation Set consists in total of three cables, which are:

24VDC, ~ 6W, max. 0.5mm
Network Box. It depends on the wiring specialist to decide from where the power will be fed in.
Power supply could be routed to the Temperature Compensation Box from the Protective
Housing, the Touch-Panel PC or even from the dropgate digital input terminal block.

RJ45 LAN, min. Cat5e, < 80m distance to the Temperature Compensation Network Box either
from Protective Housing or Touch-Panel PC

Temperature sensor head cable (15m), already installed at sensor head side, has to be
connected to the Temperature Compensation Box, see Figure 17: Terminal Wiring for the
RAYMI3COMME Box
In a dusty environment like in the gypsum wallboard production, it's strongly recommended
to install the air-purge supply to keep the sensor head and associated mirror dust-free.
Bad temperature reading influences the temperature compensation capability.
