CHAPTER
1
INTRODUCTION
The Neo-Dyn®Enclosure 3X Switches described in this manual are weather-proof,
electromechanical sensing devices designed for a wide range of applications in pneumatic
and hydraulic systems up to 10,000 psig. Models 100P, 101P, 110P, 200P, and 201P are
gauge pressure switches, Model 180P is a vacuum switch, and Model 160P is a differential
pressure switch.
The most common wetted materials of these pressure and vacuum switches include a
polyimide (Kapton) sensing diaphragm, nitrile O-ring, and aluminum alloy or corrosion
resistant steel (CRES) pressure port. CRES diaphragms and all-welded constructions are
also available in some models for corrosive pressure media and are standard on the
temperature switches.
Setpoint adjustments are easily made through the adjustable range by turning an
adjustment nut located inside the housing. On Models 101P and 201P this adjustment is
external.
The standard configuration of these switches will switch up to 15 amp at up to 250 VAC
in a single-pole configuration, and up to 11 amp at up to 250 VAC in a double-pole
configuration. When ordered with M Option, the switch is rated for currents to one amp,
but its bifurcated gold contacts will reliably switch currents in the milliampere and
microampere ranges.
These switches have CE Mark, and they all have weatherproof enclosures with IP66
ingress protection and that meet the requirements of NEMA 3. 3R, 3S, 4, 4X and 13. The
internal switch elements are UL and CSA recognized components.

INSTALLATION
Installation of these Neo-Dyn®Enclosure 3X pressure switches is straightforward.
However, they must be installed by a qualified electrician, in compliance with all local
and national electrical codes.
WARNING Electrical hazard
WARNING Do not make electrical connections while power is on.
WARNING Always check for multiple circuits.
WARNING Always make sure grounding is adequate.
WARNING Do not remove switch while under pressure.
MOUNTING
The Pressure Switch can be mounted directly to the process connection if there is no
significant vibration and the fluid lines are capable of supporting the weight. It can also
be attached to a flat surface, such as a wall or panel, using .250 in. diameter or M6
socket-head cap screws through the mounting holes that are accessed by removing the
housing cover; allow .5 in. (12.7 mm) screw length above the mounting surface. These
holes are located on two corners of a 2.72 inch (6.91 cm) square, or 3.85 inches (9.77 cm)
apart on a 45° diagonal. Do not over tighten the screws when replacing the cover.
Note that on certain models and ranges the housing of the pressure fitting has a large
outside diameter that extends below the mounting surface, requiring either a cutout in that
surface, or having the pressure fitting overhang an edge. These models are 100P and
101P, Range 1; 110P; 142P; 152P; 160P; and 180P

Enclosure 3X Pressure Switches Page 4
PROCESS CONNECTIONS
The process connections are:
Models 160P and 180P, both ports: ¼” - 18 NPT female standard. On Model 180P, the
vacuum port is on the side of the round housing, and the normal pressure port must be left
open to the atmosphere, which serves as the reference pressure.
All other pressure switches:
Wetted Material 1: ¼” - 18 NPT female standard
Wetted Materials 4-9: ½” - 14 NPT female standard
In addition, some models can be ordered with Option E (7/16”-20 SAE port); refer to
Table 7.
When installing the Pressure Switch, always:
Make sure that the unit and your system have matching threads.
Use the wrench flats provided.
Seal all joints with pipe joint sealing compound.
CAUTION Avoid excessive torque on all threaded connections.
WARNING Do not exceed the marked maximum operating pressure in normal operation.
The marked Proof Pressure is provided to give the maximum allowable pressure without
causing permanent damage to the pressure switch in the event of an over-pressure
condition. Set pressure relief/safety valves below this setting.
PROCESS MEDIA
Process media must be compatible with the wetted materials listed in Chapter 5.
Compatibility is defined by an “A” rating in the Chemical Resistance Guide for Metals
and Alloys, the Chemical Resistance Guide for Plastics, and the Chemical Resistance
Guide for Elastomers, all published by Compass Publications, and available from the
National Association of Corrosion Engineers (NACE), Houston, Texas; telephone 281
228 6200.

ELECTRICAL CONNECTIONS
An internal terminal block is standard, with a green screw for attaching the ground wire. See
See Figure 2 and
Figure 3
WARNING All field wiring must comply with requirements of the NEC or applicable local or
national electrical codes, including wire gauges and insulation temperature ratings.
Conduit seals may be required.

ADJUSTMENTS AFTER INSTALLATION
The factory-set setpoint or adjustable setpoint range is marked on the nameplate of the
switch. This section describes the adjustments needed after an Adjustable Pressure
Switch has been properly installed.
SETPOINT ADJUSTMENT
Disconnect the electrical power. Check for multiple circuits.
Disconnect the electrical power. Check for multiple circuits.
1. On all models except 101P and 201P, loosen the screws on the housing cover, and move it
aside.
2. Check the setpoints per paragraphs 4 and 0 below for precise adjustments.
3. The adjustment nut can be rotated by hand or with an open-end wrench or similar tool (use a
screwdriver on Models 101P and 201P, or turn the knob by hand if a knob is included). The
range scale is intended to be used only as an approximate guide; it indicates the increasing
setpoint.
4. To check the increasing setpoint, connect a pressure source and a calibrated pressure gauge or
transducer to the pressure port and slowly apply increasing pressure (or vacuum on Model
180P) until the switch actuates. Actuation can be noted by listening to the audible snap of the
Belleville spring, or with an ohmmeter across the appropriate terminals in the terminal block.
5. If you want to check the decreasing setpoint, slowly decrease the pressure or vacuum after
the switch has actuated and note the value at which the audible snap or an ohmmeter indicates
deactuation. Deadband may be calculated if desired by subtracting the decreasing setpoint
reading from the increasing setpoint reading.
CAUTION 6. On all models except 101P and 201P, replace the cover by moving it back into
position over the top of the housing and tightening the screws until the cover is snug
against its gasket. Do not overtighten, as this could damage the gasket.

CHAPTER

TROUBLESHOOTING
In-service problems are unlikely, but the following paragraphs suggest ways to verify any
problems that might arise:
1. Pressure Switch Leaks
If a leak is suspected, isolate the pressure switch from the rest of the system. Connect
the switch and a calibrated pressure gauge downstream from a pressure source and
shutoff valve. Apply normal system pressure, isolate the gauge and Pressure Switch
from the pressure source with the shutoff valve for at least one minute, and check for
leaks as evidenced by a drop in the gauge reading.
If a leak is verified, return the unit for repair. Contact ITT directly, or your local sales
representative or distributor (see www.neodyn.com for a contact list).
2. Failure to Switch
If application of pressure or vacuum 10% greater than the adjusted setpoint fails to
produce actuation, first check for contamination in the process connection, and verify
that the expected pressure is reaching the sensing diaphragm or piston.
If the Belleville spring can be heard to audibly snap, but an ohmmeter indicates no
electrical switching, the cause is probably stuck or burned switch contacts, or the
switch element has moved away from the position where it was synchronized with
the snap action. Return theunitfor repair.
If application of pressure or vacuum 10% greater than the adjusted setpoint fails to
produce an audible snap of the Belleville spring, there is probably a mechanical
failure or binding due to contamination. Return the unit for repair.
3. Calibration Shifts
If it is suspected that the setpoints have shifted, recheck them per paragraphs 4 and 0
of Chapter 3. If you verify unstable or drifting setpoints, return the unit for repair.
