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 require-
ments 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 gener-
ate an ignition-capable level of electrostatic charges under cer-
tain 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 600790 along with

SAFETY FUNCTION
The safety function of the certified equipment is:
‘To provide indication of a monitored valve position upon rota-
tion 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 indi-
cator 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 Indi-
cator: aluminum housing, bunaN seals, polycarbonate indica-
tor and indicator cover and stainless steel shaft and fasteners.
The suitability of these materials for the application environ-
ment is solely up to the customer.

INTRINSICALLY SAFE PROXIMITY SWITCHES
A VPX equipped with proximity switches is considered intrinsi-
cally safe when used with an appropriate switching amplifier,
also referred to as an associated apparatus, which complies
with EN 6094756:2000 or IEC 6094756:1999. The ampli-
fier 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
inductance (Lcable, Li and Lo, respectively). Where the cable
capacitance and inductance per foot are not known, the follow-
ing 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 cur-
rent. 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 instal-
lation codes, as applicable. The resistance of the ground path
must be less than 1 Ohm. Associated apparatus must not be

Sensing and Internet of Things 5
MICRO SWITCH VPX Series ISSUE F 32312068
used in combination unless permitted by the associated appa-
ratus certification. Control equipment must not use or generate
more than 250 V rms or dc with respect to earth. Where mul-
tiple circuits extend from the same piece of intrinsically safe
equipment to the associated apparatus, they must be installed
in separate cables or in one cable having suitable insulation.
Installation must be done in accordance with all local codes.

SPECIAL CONDITIONS FOR SAFE USE
• Aluminum enclosure - Care should be taken to minimize
the risk of ignition due to impact or friction.
• Potential electrostatic discharge - Clean product only with
a damp cloth.
LEVER POSITIONING
Various levers can be attached to the VPX products equipped
with the knurled shaft option. See 7CX Series Chart 1, 2 and 3
drawings for a list of lever accessories. To install or reposition
a lever, loosen the screw with a 9/64 inch hexagon key wrench,
move the lever to the desired position and securely tighten the
screw until the “teller tab” can no longer be moved by hand.
Then tighten the screw another 1/8 to 1/4 turn to assure that
the lever is tight on the shaft. Hexagon key wrenches are pro-
vided in adjusting tool set LSZ4005 for this purpose.
