DX100 (M)
TERMINATION UNIT
MAN0617 Issue 03 February 2003

Quick S
tart Guide
The DX100 (M) Termination Unit is an explosion proof active junction box that
provides a signal connection point for the Searchpoint Optima and
Searchline Excel
range of gas detectors and the associated field wiring, and a mounting
point for the
Searchpoint Optima and Optima Plus detectors. The unit is certified to UL and
CSA
standards and is intended for use in hazardous environments.
The Termination Unit also provides a digital interface between the attached gas detector
and an RS485 link to the network controller.
Note:
Gas detector digital address configuration information is
not
provided here but in
the DX100 Series Termination Units Technical Handbook.
The DX100 (M) provides:
•
terminals for connecting the gas detector and the field cabling
•
an Intrinsically Safe (IS) connection point for the Hand Held
Interrogator (SHC1)
•
a local mounting point for the Searchpoint Optima or Optima Plus gas
detector
The unit features three 3/4” NPT cable/conduit entries, two terminal blocks and a voltage
clamp with a communications link entry socket
When used with an Optima or Optima Plus, one of the unit’s three cable/conduit entries
(usually the left-hand one) is used to mount the gas detector directly to the box. The gas
detectors output a 4-20mA signal that is sent via the Termination Unit and field wiring back
to the system controller.
The voltage clamp and the external socket provide the IS connection to the
Handheld Interrogator (SHC1) which allows operator interaction with the attached gas
detector to commission, calibrate or diagnose the system. Full details about the gas
detectors can be found in their respective technical documents, which include operation of
the SHC1.
Caution:
Only the SHC1 Handheld Interrogator should be connected
to the
DX100 (M) communication link entry socket.
This guide covers the basic on-site mechanical and electrical installation of the unit. Refer
to the DX100 Series Termination Units Technical Handbook (Part No: 2104M0701) for
more detailed information about the DX100 (M).

2. SAFETY
Ensure that you read and understand this document
BEFORE
installing/
operating the equipment. Pay particular attention to the Safety Warnings.
WARNINGS
1.
The DX100 (M) Termination Unit is certified for and intended for use in
potentially hazardous areas. Install and use the DX100 (M) Termination Unit
in accordance with the latest regulations. No modifications to the unit is
permitted without reference to the relevant certifying authority
2.
Install UL approved and certified equipment including field wiring in strict
accordance with the articles of the National Electrical Code for Division 1
Hazardous Locations (NFPA 70).
3.
Install CSA approved and certified equipment including field
wiring in strict
accordance with Canadian Electrical Code, Part 1.
4.
For installations elsewhere, the appropriate local or national regulations
should be used.
5.
The Code of Practice regarding Selection, Installation, Use And Maintenance
Of Apparatus For The Detection Of Combustible Gases (Other Than For
Mining Applications Or Explosive Processing And Manufacture) must be
complied with.
6.
The DX100 (M) Termination Unit must be properly earthed to protect against
electrical shock, minimise electrical interference and comply with IS Safety
Requirements.
7.
Dismantling or repair of equipment should be carried out in the safe area
only.
8. Do not drill holes in the housing as this will invalidate the explosion protection.
9. In order to maintain electrical safety, the unit must not be operated in
atmospheres with more than 21% oxygen.
10. Do not open the enclosure in the presence of an explosive atmosphere.
CAUTIONS
Only the Handheld Interrogator (SHC1) must be connected to the
Termination Unit’s communication link entry socket.
