1. Safety Instructions - Definition of Terms

Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.

NOTICE

Used without the safety alert symbol indicates a potential situation which, if not
avoided, may result in an undesirable result or state, including property damage.

2. Hazard-Free Use

This device left the factory in proper condition to
be safely installed and operated in a hazard-free
manner. The notes and warnings in this document
must be observed by the user if this safe condition
is to be maintained and hazard-free operation of
the device assured.

Take all necessary precautions to prevent damage
to the device due to rough handling, impact, or
improper storage. Do not use abrasive compounds
to clean the device, or scrape surfaces with any
objects.

Configuration and setup procedures for this device
are described in this manual. Proper configuration
and setup are required for the safe operation of
this device.

The control system in which this device is installed
must have proper safeguards to prevent injury to
personnel, or damage to equipment, should failure
of system components occur.

3. Qualified Personnel

A qualified person in terms of this document is one
who is familiar with the installation, commissioning
and operation of the device and who has appropriate
qualifications, such as:

• Is trained in the operation and maintenance of
electric equipment and systems in accordance
with established safety practices.

• Is trained or authorized to energize,
de-energize, ground, tag and lock electrical
circuits and equipment in accordance with
established safety practices.

2

• Is trained in the proper use and care of personal
protective equipment (PPE) in accordance with
established safety practices.

• Is trained in first aid.

• In cases where the device is installed in a
potentially explosive (hazardous) location - is
trained in the operation, commissioning,
operation and maintenance of equipment in
hazardous locations.

The VSM must only be installed, commissioned,
operated and repaired by qualified personnel.

All installation, commissioning, operation and
maintenance must be performed under strict
observation of all applicable codes, standards and
safety regulations.

Reference is specifically made here to observe
all applicable safety regulations for electrical
equipment installed in potentially explosive
(hazardous) locations.

5. Introduction

The Bray Series 5A and 5B Intrinsically Safe
Valve Status Monitors (VSMs) provide visual and
electrical indication of position of any VDI/VDE
3845 compliant quarter-turn device. The S5A and
S5B I.S. VSMs are designed to operate in multiple
hazardous locations.

6. Principle of Operation

Bray Series 5A and 5B I.S. VSMs are comprised of a
NEMA Type 4/4X, IP66/67 housing (resin housings
are IP66/67/68 (1 meter, 1 hour) with external
position indicator and two conduit entries, cam
shaft with self-locking cams, elevated terminal block,
internal grounding screw, and mounting bracket.

The VSM is coupled to the quarter turn device via the
cam shaft. Rotation of the cam shaft, in turn, drives
switch activation. The angular position in which
the switches activate can be adjusted through the
self-locking cams. Proximity activation of switches
provides electrical feedback of achieved position
through field wiring to a control network.

7. Hazardous Locations

The S5A and S5B I.S. (aluminum and resin trims) are
designed and certified to operate in the following
hazardous locations :

ATEX

II 1G Ex ia IIC Ga T6
II 2G Ex ia IIC Gb T6

IECEx IECEx UL 18.0073X
Ambient 1G: -25°C ≤ Ta ≤ 49°C

2G: -25°C ≤ Ta ≤ 65°C

Elevation 2000m max

The S5A (aluminum trim only) and S5B (aluminum
and resin trims) I.S. are also certified to operate in
the following hazardous locations :

NEC 500 Class I Division 1

Groups A, B, C, & D T6
Class II Division 1
Groups E, F, G T85°C

NEC 505 Class I, Zone 0, AEx ia IIC T6

Class I, Zone 1, AEx ia IIC T6
CEC Ex ia IIC Gb T6
Ambient Zone 0: -25°C ≤ Ta ≤ 49°C

Zone 1: -25°C ≤ Ta ≤ 65°C
Elevation 2000m max

For cULus applications, the S5B resin housing is
only intended for use with flexible conduit.

In addition to IO&M Manual instructions, it is
required to follow all instructions specified in
Control Drawing: WD-000393.

Installation, Operation and Maintenance Manual

Substitution of components may impair intrinsic
safety.

NOTICE

The Bray Series 5A and 5B I.S. VSMs are compliant
to the IEC/EN 60079-11 section 6.3.13 dielectric
strength requirement.

8. Pre-Installation Storage

Bray Series 5A and 5B I.S. VSMs are not weatherproof
until properly installed on the quarter-turn device
or prepared for storage. Bray cannot accept
responsibility for deterioration caused on-site once
the cover is removed.

NOTICE

Units are shipped with two screw-in plugs
(aluminum housing) or peel-off decal (resin
housing) to prevent foreign matter from
entering the unit through the conduit openings.
To prevent condensation from forming inside
these units, maintain a near constant external
temperature and store in a well-ventilated, clean,
dry room away from vibration.

Store units on a shelf or wooden pallet in order
to protect against dampness.

Keep units covered to protect against dust and
dirt.

Storage Temperature should be maintained
between -25°C and 65°C.

S5A and S5B I.S. VSMs must be used in
conjunction with a third party approved
barrier that meets conditions specified in
the control drawing: WD-000393.

Enclosure may contain aluminum. Care must be
taken to avoid hazard due to impact or friction

Resin housings pose an electrostatic charging
hazard. See Control Drawing: WD-000393
