DVC100 (I) MK2 Termination Unit

Installation Guide

1. INTRODUCTION

The DVC100 (I) MK2 Termination Unit is an ATEX and IECEx Certified junction box that provides a signal connection point and mounting point for the Honeywell Analytics Searchpoint Optima Plus gas detectors.

Caution: The DVC100 (I) MK2 Termination Unit can only be used with Searchpoint Optima Plus gas detectors.

The unit is ATEX and IECEx certified and is intended for use in hazardous areas.

The DVC100 (I) MK2 provides:

The unit features:

The large (M25) entry is used to mount the Searchpoint Optima Plus gas detector directly to the box. The Optima Plus outputs a 4-20mA signal that is sent via the Termination Unit field wiring back to the controller.

The voltage clamp and the external socket provide the IS connection to the Honeywell Analytics Handheld Interrogator (SHC1). The SHC1 allows the operator to communicate with the attached gas detector to commission, calibrate or diagnose the system.

Full details about the Searchpoint Optima Plus units can be found in their documentation, which includes operation of the SHC1.

Caution: Only the Honeywell Analytics SHC1 Handheld Interrogator must be connected to the DVC100 (I) MK2 Communications Link Entry Socket.

Honeywell Analytics Limited reserve the right to change or revise the information supplied in this document without notice and without obligation to notify any person or organisation of such revision or change. If further details are required that do not appear in this document contact Honeywell Analytics Limited or one of its agents.

4. INSTALLATION

GeneralInstallationGuidelines

1. Read the Warnings and Cautions at the beginning of this document and all the relevant instructions before starting any of the installation procedures.

2. Identify external cable requirements and the necessary cable entry ports to be used on the Termination Unit.

3. Refer to the documentation for the associated control system for details about external network connection information, field wiring, interconnections, etc.

4. Refer to the associated Searchpoint Optima handbook for details about the gas detector.

MECHANICAL INSTALLATION

MechanicalInstallationGuidelines

1. Identify a suitable location where the Termination Unit can be mounted. The unit should be fitted to a flat surface.

2. When fitting a Termination Unit consideration should be made regarding the probability of mechanical impacts and interference from other equipment and apparatus.

Procedure

This procedure describes how the DVC100 (I) MK2 is installed at the mounting location and then the Optima Plus gas detector is fitted to the Termination Unit.

(1) Securely fit the Termination Unit at the required monitoring point.

Use the four Termination Unit mounting holes (visible after the lid is removed). Ensure the communications link entry socket connector is located at the bottom. This is to fulfil the requirement to position the Optima Plus sensor horizontally so that the risk of fouling the gas detector's optical surfaces is reduced.

(2) Remove the Termination Unit lid.

(3) Fit the Optima Plus detector to the left-hand (M25) entry.

(4) Fit ATEX / IECEx approved cable glands to the Termination Unit cable entries as required.

(5) Fit the external field wiring through the cable glands and secure.

(6) Terminate the Optima Plus and field wiring.

Refer to ElectricalInstallation.

ELECTRICAL INSTALLATION

ElectricalInstallationGuidelines

1. Isolate all associated power supplies and ensure that they remain OFF during the procedures.

2. Ensure that approved and certified cable glands have been fitted to the Termination Unit cable entries where used for field wiring, with sealing washers where necessary to maintain the ingress protection rating.

3. Ensure that any cable gland locking rings are fitted before terminating the cables.

4. Ensure that approved and certified blanking plugs are fitted to all unused Termination Unit cable entries.

5. The Termination Unit must be earthed using the internal earth terminal.

6. Suitable crimps and/or ferrules must be fitted when connecting more than one wire to a Termination Unit terminal.

7. The field terminals of the Termination Unit accept single or multi-stranded wire up to 2.5mm2 (14AWG). Cables should be routed carefully to avoid physical and environmental hazards such as mechanical stress and high temperatures.

8. In order to ensure correct operation and to meet requirements for EMC, it is recommended that all field cables are screened with the cable screen connected at one end only.

9. Avoid cabling schemes that create earth loops.
