ULTIMA® X Series Remote Sensor Module Installation
The remote sensor module is used in conjunction with the ULTIMA X
®
Series with-
out sensor. It can be installed similarly to the Gas Monitor bearing in mind the max-
imum separation distance [
(1) Permanently attach a tube with an inner diameter of 6 mm to the SensorGard.
(2) Route the tube to the ULTIMA X Gas Monitor ensuring there are no kinks,
leaks or obstructions.
(3) Secure the tube close to the monitor; it is used to deliver calibration gas to the
sensor.
The following are required for assembling the remote sensors:
-
5 conductors for instruments from the ULTIMA X
®
Series
-
4 conductors for instruments of the ULTIMA XIR type.
ULTIMA X
®
Series instruments contain a terminal strip for 5 conductors of up to
2.5 mm
2
cross-section.
(4) Remove cover from the remote sensor module.
Attention!
The ULTIMA X
®
Series remote sensor module must be installed only in
compliance with the applicable regulations, otherwise safe operation of
the instrument is not guaranteed.
Disconnect the power source to the ULTIMA X monitor before connec-
ting the cable.
Some installations require metal pipe or metallic conduit. In these ca-
ses, separate conductors or unshielded cable may be used.
In the case of unprotected wiring, screened conductors or cables must
be used to minimise the possibility of electrical interference or contact
with other voltages.
The screened cable used must comply with applicable regulations.
