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.

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

11. Field Wiring
Bray Series 5A and 5B I.S. are assembled with
numbered terminal blocks on a printed circuit
board designed to conform to Intrinsically Safe
requirements. Bray Series 5A VSMs contain a 4-pole
terminal block, while the Series 5B VSMs contain a
12-pole terminal block. All switches are pre-wired
into the terminal block. Several features have been
designed to help ease field wiring:
• Terminal blocks are angled towards the cover
opening.
• W iring diagram is attached to the inside of cover.
• Two side conduit entries are available for all
models. Additional rear conduit entry available
on S5B resin trim.
Turn off all power and lock out service panel before
installing or modifying any electrical wiring.
Observe all applicable safety regulations for
electrical equipment installed in potentially
explosive (hazardous) locations.
NOTICE
• Do not re-machine the conduit entry threads or
create any new holes in the enclosure.
• Do not remove the screw-in conduit plugs
(aluminum housing) or peel-off decal (resin
housing) until it is time to wire into the unit's
terminal blocks.
• Do not tamper with or modify any exposed
O-rings or gaskets.
• A minimum of 18 AWG wire is recommended
for all field wiring.
• The terminals inside the VSM accept wire sizes
ranging from 14 to 20 AWG.
• The conduit connections must be properly sealed
to maintain the weatherproof integrity of the
VSM enclosure.

required to meet application needs, weatherproof
requirements, and hazardous location
requirements.
4. Terminate the field wiring per the wiring
diagram attached to the inside of the cover.
5. Tighten wires in terminal block to 3.5 lb-in
[0.4 Nm].
6. Re-attach VSM cover once position
adjustment has been completed.

Reference Cover Installation.
Installation, Operation and Maintenance Manual
To ensure intrinsic safe operation, use cable ties
to mount field wiring to the printed circuit board.
NOTICE
Do not use power tools to tighten the cover screws.
If the valve status monitor is mounted
on a vertical pipe, it is recommended
that the unit be positioned with the
conduit entries on the bottom to prevent
condensation from entering through the
conduits.
In all cases, the conduit should be
positioned to prevent drainage into
the valve status monitor. In some cases
the use of an "S" pipe can be used to
prevent water ingress.
Refer to the figures on the right.

12. Reversal of Visual Indication
Visual indication can be reversed per application
requirements without the need to re-mount the
VSM. This may also be appropriate if the standard
orientation of the VSM is not convenient for the
application such as field wiring entry direction do
not align with conduit entries.
Observe all applicable safety regulations for
electrical equipment installed in potentially
explosive (hazardous) locations when making
modifications to the assembly.
NOTICE
Ensure that open and close cams are properly set
after any modification to visual indication.
Bray Series 5A and 5B I.S. VSM visual indication
can be reversed as follows:
1. Remove all four Indicator dome bolts with
lock washers.
2. Rotate the indicator dome 90° in either
direction.
3. Remount the indicator dome bolts with lock
washers.
a. Tighten bolts in a cross pattern to
13-18 lb-in [1.5-2 Nm] for aluminum
housing or 5.3-7.5 lb-in [0.6-0.85Nm]
for resin housing.
b. Ensure that o-ring is secure in indicator
dome and is not pinched when dome is
re-installed.
NOTE: The indicator dome of the 5A Resin VSM is
part of the cover. Remove the cover for indication
reversal.

13. Position Adjustment
A single or doubled lobed cam is provided for every
independent/main switch. Double lobed cams are
provided when the switch configuration could
include an auxiliary switch. Double lobed cams
will activate both main and auxiliary switches at
the same time.
Cams are mounted to the indicator shaft, alternating
between red and yellow and are independently
adjustable by hand in 3.6° increments. No special
tools are needed for this adjustment. The self-locking
design ensures that cams will not slip position.
The bottom red cam is intended to indicate the close
position while the bottom yellow cam is intended
to indicate the open position. Both of the switches
associated with these cams are labeled accordingly.
An additional red and yellow cam may be installed
for most switches and can be used for mid-travel
position indication or to provide an additional
auxiliary open and close indication. Mid-travel
switches are unlabeled.
Closed Travel Indication Adjustment
1. Operate the quarter turn device until it
reaches the desired closed position.
2. Pull the bottom red close cam upwards
towards the yellow cam to disengage the
cam from the fixed cam holder.
3. While the cam is disengaged, rotate the cam
to the position that will activate the close
switch.
a. NOTE: Do not attempt to adjust cams
prior to disengaging the cam from the
fixed cam holder.
4. Release the cam and allow the locking spring
to re-engage the cam with the fixed cam
holder.
Open Travel Indication Adjustment
1. Operate the quarter turn device until it
reaches the desired open position.
2. Push the bottom yellow open cam towards
the bottom red cam to disengage the cam
from the fixed cam holder.
3. While the cam is disengaged, rotate the cam
to the position that will activate the open
switch.
a. NOTE: Do not attempt to adjust cams
prior to disengaging the cam from the
fixed cam holder.
4. Release the cam and allow the locking spring
to re-engage the cam with the fixed cam
holder.
Mid-Travel Indication Adjustment
1. Operate the quarter turn device until it
reaches the desired mid-travel position.
2. Disengage the cam from the cam holder.
a. NOTE: Mid-travel cams are disengaged
similarly to the open and close cams.
3. While the cam is disengaged, rotate the cam
to the position that will activate the midtravel switch.
a. NOTE: Do not attempt to adjust cams
prior to disengaging the cam from the
fixed cam holder.
4. Release the cam and allow the locking spring
to re-engage the cam with the fixed cam
holder.
