mWARNING
This equipment has a non-conducting coating and may
generate an ignition-capable level of electrostatic charges
under certain extreme conditions. The user should ensure
that the equipment is not installed in a location where it may
be subjected to external conditions (such as high pressure
steam) which might cause a build up of electrostatic
charges on non-conducting surfaces. Additionally, cleaning
of the equipment should be done with a damp cloth.

GENERAL INFORMATION
The VPX Valve Position Indicator is designed specifically for
use in potentially hazardous locations where explosive gases or
dusts may be present. To comply with explosion proof requirements the VPX has flame paths within the housing, which cool
any explosion below the ignition temperature before it reach
explosive gases or dusts in the surrounding atmosphere. Flame
paths on the VPX are 1) an extended shaft between the switch
cavity and head and 2) the cover-housing flange joint.
The equipment has a non-conducting coating and may generate an ignition-capable level of electrostatic charges under certain conditions. The user should ensure that the equipment is
not installed in a location where it may be subjected to external
conditions (such as high pressure steam) that might cause a
build up of electrostatic charges on non-conducting surfaces.
Additionally, cleaning of the equipment should be done with a
damp cloth.

ENVIRONMENTAL PROTECTION
The VPX Valve Position Indicator is often ideal for outdoor use
or in potentially adverse environments. The enclosure is sealed
for protection against corrosion, water, dust and oil as defined
in UL 50E to enclosure types 4, 4X, 6, and 13 as well as to IP66
and IP67 as defined in IEC 60529. An ingress protection rating
of IP66 was confirmed according to IEC 600790 along with
the hazardous location approvals. A rating of IP67 was confirmed by Honeywell according to IEC 60529.

SAFETY INTEGRITY LEVEL (SIL)
SIL 3 per IEC 615082 as evaluated by Sira Certification Service.
SAFETY FUNCTION
The safety function of the certified equipment is:
‘To provide indication of a monitored valve position upon rotation of the shaft via switches or proximity sensors and a visual
indicator.’
UNDETECTABLE DANGEROUS FAILURE
‘If an undetected dangerous failure of the VPX Valve Position
Indicator were to occur it would fail to respond and would give
an incorrect indication of valve position. However this would
only ever occur if both the switches or sensors and visual indicator were to have failed’.
PROOF TEST REQUIREMENTS
A maximum proof test interval of 1 year is recommended for the
VPX products. The proof test procedure must be carried out by
a competent person who is trained in safety operations and is
familiar with the VPX product. A generic proof test procedure
can be found in Table 2, however depending on application may
vary.
MATERIALS OF CONSTRUCTION
The following materials are used in the VPX Valve Position Indicator: aluminum housing, bunaN seals, polycarbonate indicator and indicator cover and stainless steel shaft and fasteners.
The suitability of these materials for the application environment is solely up to the customer.
ELECTROMECHANICAL SNAP ACTION

INTRINSICALLY SAFE PROXIMITY SWITCHES
A VPX equipped with proximity switches is considered intrinsically safe when used with an appropriate switching amplifier,
also referred to as an associated apparatus, which complies
with EN 6094756:2000 or IEC 6094756:1999. The amplifier contains a dc source to supply the control circuit and is
controlled by the variable internal resistance of the proximity
switch. This amplifier is placed outside of the hazardous area. A
diagram of the typical installation is shown in Figure 3.
Cable capacitance, Ccable, plus intrinsically safe equipment
capacitance, Ci, must be less than the marked capacitance, CO,
shown on any associated apparatus used. The same applies for

capacitance and inductance per foot are not known, the following values shall be used: Ccable = 200 pF/m., Lcable = 1 μH/m.
The associated apparatus output current must be limited by a
resistor such that the output voltage-current plot is a straight
line drawn between open-circuit voltage and short-circuit current. The associated apparatus must be installed in accordance
with its manufacturer’s control drawing. When required by the
manufacturer’s control drawing, the associated apparatus must
be connected to a suitable ground electrode per local installation codes, as applicable. The resistance of the ground path
must be less than 1 Ohm. Associated apparatus must not be
