MULTIXPLO AND MULTITOX DETECTORS
OPERATING MANUAL
18 NOSP17665
Revision 02a
4.2.4 Magnets identification
The magnets are identified by two stickers “PG1” and “PG2” fixed on the housing.
4.3 Electric Connection
Never adjust electrical connections when detectors are powered. Maintenance
must be undertaken by qualified staff. Observe safety site rules.
The MultiXplo and MultiTox are sensors with standard current output 4-20mA or 0-22mA. The
connection can be on 3 or 4 wires. The 4 wires configuration allows insulation between the signal
and power loops.
We recommend using an armoured and shielded cable, type NF M 87 202, in accordance with
the requirements for hazardous areas and NF C 15 100. Other cables can be used if they are
compliant with the local regulations and standards.
The table below shows the maximum cable lengths based on the wire cross section and the supply
voltage delivered by the detection unit.
Min. single wire cross section mm²/AWG 0.5 (20) 0.9 (18) 1.5 (16) 2.5 (13)
Supply voltage 24VDC 288 m 505 m 893 m 1000 m
Supply voltage 24VDC -10% 173 m 303 m 536 m 926 m
NB: Those values are calculated for a minimum supply voltage of 18VDC at the sensor level and
for the maximum consumption of the detector (5W)
