OUNTING

GENERAL

NEMA 1 and NEMA 4X transducers can be mounted in any position.

DIRECT MOUNTING

PIPE

• Any NEMA 1 transducers may be supported by its own plumbing for air supply and output. NEMA 4X transducers may
also be supported using 1/2" explosion proof conduit in the electrical port.

PANEL

• NEMA 1 transducers may be mounted to a panel with two No. 10-32 screws using threaded holes in the back of a trans-
ducer or with two to four No. 8-32 screws using threaded holes in the bottom of a transducer.

• NEMA 4X transducers may be mounted to a panel with three No. 10-32 screws using threaded holes in the back of a
transducer or with four No. 8-32 screws using threaded holes in the bottom of a transducer. In the case of back-mount­ing, if the panel extends towards the screw-on cover, a 3/16-inch-thick spacer MUST be used between the back of the
transducer and the panel in order for the panel to clear the transducer's screw-on cover.

RECAUTIONS TO BE OBSERVED DURING INSTALLATION

P

-4109/1104 IP510, EP510, IP511, EP511 SERIES

M

These Transducers were tested at the EMC Test Centre, Dunfermline, Fife, KY11 5LB to the Electromagnetic
Compatibility Directive effective January 1, 1996. The relevant EMC specifications tested were the following:
EN 50081-1 (1992) and EN 50082-2 (1992). A Technical Construction File, Serial #107 was written and
Certificate of Conformity issued by a Competent Body.

N 50081-1 (1992): Test results confirmed that no precautions need to be observed during installation regarding electro-

E
magnetic emissions from the 510 or 511 Series Transducers.

EN 50082-2 (1992): The following precautions should be taken during installation to maintain the advertised accuracy speci­fications. The input wiring to the transducer should be isolated from other high voltage transient wiring. The momentary
switching on and off of nearby relays, motors, or other high capacitive or inductive loads can have a minor effect on the
accuracy specification (0.25% of Span). Any change in output pressure is minimal and momentarily, and is considered to be
within the performance capabilities. Use of a ferrite bead collar on the input wires entering the transducer is recommended
should installation next to high electromagnetic interference be necessary.

WARNING: In explosive atmospheres, electrical power must be removed from the transducer before attempting to
remove the cover and until the cover is fully reinstalled. Failure to do so may result in electrical spark or explosion.
CAUTION: Care must be used when inserting wires into the NPT port. Wires must not enter below the circuit board
due to sensitive mechanical components.

DIRECTIONS

1. Remove the cover (see WARNING above).

2. Bring wiring to the terminal block, located on the circuit board, through 1/2 NPT electrical conduit connection. 18
A.W.G. is recommended; 14 A.W.G. is the maximum wire size. Connect wires to the terminal block per TABLE 2. Care
must be exercised to prevent damage to delicate internal parts when inserting wiring through the 1/2” NPT conduit
opening.

3. An internal grounding screw is provided on all units to facilitate separate ground when required. An external grounding
lug is also provided on NEMA 4X enclosures.

Reinstall the cover tightly using all o-rings and locking devices to insure compliance with Agency Approvals.

WARNING: In explosive atmospheres, electrical power must be removed from the transducer before attempting to
remove the cover and until the cover is fully reinstalled. Failure to do so may result in electrical spark or explosion.
CAUTION: Only attempt electrical adjustments as described below. Any mechanical adjustments made will void the
warranty.

1. Remove the cover to gain access to the "SPAN",(marked S), "FINE ZERO",(marked Z) and the "DAMPING", (3/4 turn low
profile) potentiometers. The unmarked pot “COURSE ZERO”, is used only for major calibration range changes. This
adjustment should only be attempted by factory trained personnel. For NEMA 1 enclosure, just slide open the access
door on the top of the cover.

2. Set electrical input signal to 0% (e.g. 4 mA or 0 VDC).

FORWARD ACTING UNITS: Using "FINE ZERO" potentiometer, adjust output pressure to 0% output (e.g. 3 psi).

3.

4. Set electrical input signal to 100% (e.g. 20 mA or 10 VDC).

5. FORWARD ACTING UNITS: Using "SPAN" potentiometer, adjust output pressure to 100% output (e.g. 15 psi).

6. Repeat steps 2 through 5 until output pressures are properly set.

NOTE: Under certain circumstances, output pressure may exhibit cycling action. To eliminate this condition, use the
"DAMPING" potentiometer.

7. Reinstall cover using original screws and gaskets, if equipped.

MAINTENANCE

When used properly, these transducers should provide more than one million cycles without failure. If a situation should
occur in which the transducer's behavior is abnormal, the cause is usually related to a pneumatic problem.

ELECTRICAL MAINTENANCE

An electrical problem must be isolated by a skilled technician. The power source and all wiring should be checked first.
Circuit board failures are very rare, and can be confirmed by the following method. Loosen the screws, or posts that hold
the circuit board in place. Unplug the blue connector from the circuit board, and insert two small pieces of wire into the con­nector.

IMPORTANT: Connect a current source with the polarity as follows. Positive to the (RED) coil wire and Negative to the
(BROWN) coil wire of 10 mA to the connector, which powers the yellow coil. With supply pressure on, the unit should pro-

duce an output pressure equivalent to 80% or more of the maximum output pressure. If there is little or no output, then the
unit is clogged. Should it produce an adequate output pressure, then the circuit board is the primary suspect. The unit must
be returned to the factory for repair.

PNEUMATIC MAINTENANCE

All 510 and 511 Series transducers also have an internal orifice filter, but if contaminates do invade the transducer, they can
clog the internal orifice and block the flow, or jam open the internal supply valve. The problem can be corrected through
replacement of the orifice (see TABLE 5: KITS) or by cleaning the internal supply valve, or both.

EPLACING ORIFICE:

R

his can be accomplished without removing the unit from its mounting or plumbing.

T

1. Turn off supply pressure and unscrew the brass orifice assembly located on the side of the housing with the gauge
port.

NOTE: Small sealing o-ring may remain inside of the housing. If it does, remove it with a paper clip or some other small
probe. The replacement assembly will contain this o-ring.

. Install the new orifice assembly making sure the o-ring is seated on the end of the screw.

2

CLEANING INTERNAL SUPPLY VALVE:

1. Turn off the supply pressure.

2. Use a 9/16" socket or wrench to unscrew the brass plug in the bottom of the transducer.

NOTE: Take care not to lose the supply valve spring which is retained by the bottom plug.

3. Clean out any dirt or debris and reassemble, making sure the stem of the supply valve is nested in the supply valve
spring.

AGENCY APPROVALS, SPECIAL NOTES, AND CAUTIONS

A

INTRINSIC SAFETY

All 510 and 511 Series transducers are rated intrinsically safe by both FM and CSA for:

CLASS I, DIVISION 1, GROUPS A,B,C,D HAZARDOUS LOCATIONS.

Proper FM-approved intrinsically-safe wiring requires external FACTORY MUTUAL RESEARCH CORPORATION ENTITY­APPROVED SINGLE-CHANNEL barriers to be selected, based upon MAXIMUM ENTITY PARAMETERS of 510 and 511 Series
transducers:

ENTITY PARAMETERS:

Vmax = 28 V, Imax = 150 mA, Ci = 0.22uF, Li = 0 mH.
Voc and Isc of a barrier shall not exceed Vmax and Imax of the transducer.
(Li + Lwiring) and (Ci + Cwiring) shall not exceed La and Ca of a barrier.

NOTICE: For proper FM and CSA approved intrinsically-safe wiring, request Drawing Number 990-439-000 from the
Factory.

NONINCENDIVE

All 510 and 511 Series transducers are approved as NONINCENDIVE by FM and approved as suitable by CSA for:

CLASS I, DIVISION 2, GROUP A, B, C, D HAZARDOUS LOCATIONS.

A barrier is not necessary when these transducers are in these locations.

ENCLOSURES

Compliance with NEMA 4X and CSA ENC4 enclosure ratings require that the screw-on cover has the O-ring installed. In case
of a need for replacement parts, see TABLE 3.
