Detection Of Faults In An In Floor Heating System - Chauvin Arnoux LOCAT-N C.A 6681 Bedienungsanleitung

3.2.4

DETECTION OF FAULTS IN AN IN FLOOR HEATING SYSTEM

Preconditions:

The circuit measured must not be live.

All unused lines must be earthed as shown in Fig. 13a.

Connect the two transmitters (if two transmitters are used) as shown in
Fig. 13b.

The measurement method is identical to that used in §3.1 Getting started
Fig.13a

If there is a screen above the heating wires, there may not be an earth
connection. If necessary, separate the shielding from the earth connection.

There must be earthing, and there must be a long distance between the
earthing terminal of the transmitter and the line to be located. If this distance
is too short, the signal and the line cannot be located precisely.

A second transmitter is not essential for this application.
For an application with only one transmitter, refer to Fig. 13a.

When the line is traced, the place at which the signal received by the receiver
falls off suddenly is the location of the break.
Refine the detection by setting the power level transmitted by the
transmitter and the sensitivity of the receiver in manual mode.
