FLK Gas Sampling System - MPIP - Free

SQ255 Control Unit
2. Installation
2.1 General information
The control box is constructed such that it can be easily mounted. Fixing on a mounting frame is possible.
2.2 Mounting the control cabinet
The control cabinet can be set up in a control room protected from dust - normally in the same room as the analyzer cabinet.
A socket for service purposes should be provided.
2.3 Electrical connections
The electrical connections are implemented according to the regulations from the local power supply utility and of the
relevant country.
The cable for the connection of the devices is not included in the supplied items and should therefore be provided by the user
according to our specifications. The required cable and the details about the cable connections can be taken from the wiring
diagrams in the supplied wiring manual.
However, it should be ensured that high flexibility, temperature resistant cables are used for the connection to the retraction
device (valve combination). These must also be suitable for medium, mechanical stresses. In this respect particular care must
be paid during laying (coolant operating temperature with hoses up to 250°C). The cables must not come into contact with
any hot parts when the probe traverses.
Control cables normally found in the relevant cement works can then be used from the connection point (the centre of the
retraction device).
The electrical supply cables on the heat exchanger unit are preferably implemented in steel conduit to the control
cabinet. Here it should be ensured that these pipes are laid at a distance > 10cm from the hot pipes, the cooler
and the coolant pump. Top laying is the preferred method for the feed cables.
All cables must be lead into the cable entries provided in the control boxes.
2.4 External cable connection
The electrical connections are implemented according to the regulations of the local power supply utility and of the relevant
country.
The cables between the control cabinet (SQ255), heat exchanger (SQ254) local control station (SQ257), analyzer cabinet and
valve combination (SQ253) are not included in the supplied items and must therefore be supplied to our specifications by the
user. The required cable and the details about the cable connections can be taken from the wiring diagrams in the supplied
wiring manual.
The cables must be routed through the provided PG screwed glands, sealed and again clamped. The fixtures for the cables,
measuring gas lines and compressed air hose should be produced by the user depending on the installation.
Note:
See general operating manual Chapter 2.10, Electrical connections.
