The 12 volt power supply can be connected to the points marked 0 and 12 V
on the
Surveyor 4B
terminal block (see Figure 2, Item2).
The
Surveyor 4B
must be protected on the upstream side by a fuse (630mA)
with time-delay.
The cable must have a minimum cross section of 1.5 mm².
Power consumption: 5.8 W max. (detector connected).
Explosimetric detectors
•
Only explosimetric detectors of the "bridge" type can be connected to
the SV 4B.
•
Surveyor 4B
and the detector are connected together by a shielded
cable with three active conductors. The shielded cable is to be
connected to the earth to EMC constraints at one end only.
•
Terminals C1, C2 and C3 of
Surveyor 4B
and the detector are to be
connected in opposite mode (Figure 3).
