WARNING! READ BEFORE INSTALLATION



GENERAL:

A failure resulting in injury or damage may be caused by excessive
overpressure, excessive vibration or pressure pulsation, excessive in­strument temperature, corrosion of the pressure containing parts, or
other misuse.

OVERPRESSURE:

Pressure spikes in excess of the rated overpressure capability of the trans­mitter may cause irreversible electrical and/or mechanical damage to the
pressure measuring and containing elements.

Fluid hammer and surges can destroy any pressure transmitter and must al­ways be avoided. A pressure snubber should be installed to eliminate the
damaging hammer effects. Fluid hammer occurs when a liquid flow is sud­denly stopped, as with quick closing solenoid valves. Surges occur when flow
is suddenly begun, as when a pump is turned on at full power or a valve is
quickly opened.

Liquid surges are particularly damaging to pressure transmitters if the pipe is
originally empty. To avoid damaging surges, fluid lines should remain full (if
possible), pumps should be brought up to power slowly, and valves opened
slowly. To avoid damage from both fluid hammer and surges, a surge chamber
should be installed.

Symptoms of fluid hammer and surge’s damaging effects:

• Pressure transmitter exhibits an output at zero pressure (large zero offset).

• Pressure transmitter output remains constant regardless of pressure

• In severe cases, there will be no output.

FREEZING:

Prohibit freezing of media in pressure port. Unit should be drained to prevent
possible overpressure damage from frozen media.

STATIC ELECTRICAL CHARGES:

Any electrical device may be susceptible to damage when exposed to static
electrical charges. To avoid damage to the transmitter observe the following:

• Ground the body of the transmitter BEFORE making any electrical
connections.

• When disconnecting, remove the ground LAST!



Note: The shield and drain wire in the cable (if supplied) is not connected to the
transmitter body, and is not a suitable ground.

5. MOUNTING

5.1 General

The GC52 was designed to be mounted using the bracket supplied.
Pressure connections via the (2)

1

⁄4 NPT female pressure ports. Al-

though the display can be rotated in 90 degree increments by remov­ing the display cover it is preferable to orientate the electrical
termination downward, particularly in applications where protection
from the environment is required.

5.2 Mounting Orientation

It is preferable to orientate the unit with the pressure ports either
downward or upward. If mounting with pressure ports to the side an
“orientation effect” will be seen at zero pressure as the pressure gen­erated by the silicone oil fill will appear as a zero offset. If mounting in
this manner this effect may be taken out by re-setting zero in final
mounting orientation.

5.3 Installing Pressure Port Manifold
(1) Mounting 25.4mm Manifold (

1

⁄4˝ NPT female ports)

Manifold is secured using the (4) socket head bolts (M4x40) and
appropriate allen wrench which is supplied. Check for dust and
dirt on the O-ring and seal area, clean if necessary, before in­stalling to ensure proper connection. The direction of the manifold
is not important, determine best position by ability to operate the
equalizing valve.The equalizing valve is used to open both ports
to the line pressure at time of installation. Once installed and the
system has been pressurized the valve needs to be closed to iso­late the low and high pressure sides of the device.

Tighten the equalizing valve with a torque of 0.75 ft-lbs±15%.
When loosening the valve do not back off by more than three
turns from the closed position.

(2) Panel Mounting

Similar to (1) above except that the PX5200 is put between the
manifold and the bracket and then the (4) socket head bolts
(M4x40) are installed.

Note: High (H) and Low (L) pressure
sides of the device are marked on the
yellow label affixed to the housing of
the unit.

Install the high pressure side of the ap­plied differential pressure in the pres­sure inlet of the high pressure side (H)
and the low pressure side in the pres­sure inlet of the low pressure side (L).

(Refer to the outline drawing of section 14.)
After the piping is completed check for leaks.

Use caution when installing to keep metal chips and other debris from
entering pressure transmitter. In addition, when sealing tape is used,
do not apply to last two threads at the end of the fitting

Note:

• When transporting and / or mounting do not apply excessive shock
or use device as a step.

• The piping should be of proper length so as not to apply load to the
connection point on the transmitter.

• At the time of mounting or when bleeding air from the device be sure
to open the equalizing valve with a flathead screwdriver so that ex­cessive pressure (more than the allowable maximum differential pres­sure) is not applied to the differential pressure sensor. Maximum torque
to apply to equalizer valve is 0.75 ft-lbs ±5%.

7. WIRING

7.1 Cable/Wire Specifications

Use appropriate cable described below which is suitable for power
supply requirements and ground to housing.

Terminal Strip

Cable
Requirements

SMKDSP1.5/2-5.08 Phoenix Contact

• Two core shielded cable

• Cable outer diameter: 0.35˝ to 0.47˝ 9-12mm
(Required for correct installation with Cable
Gland option)

• Wire Gauge: 14-22 AWG (multi-strand or solid)

7.2. Wiring Instructions

• To reduce potential for noise do not run pressure transmitter cable /
wires alongside (same conduit as) high voltage (line power) lines.
For optimum results use dedicated conduit for PX5200 cable / wires.

• If using the Cable Gland termination option must use cable within
previously noted diameters to maintain environmental ratings.

• When connecting shield / drain wire, only connect one end which
should be at the receiver ground.

• Wiring stripping instructions, remove cable jacket 2-3˝ and strip wires
±0.25˝. Shield / drain wire should not be exposed at the pressure
transmitter termination.

• Remove cover and carefully remove the display to access the termi­nal strip, take care not to mishandle the display and associated elec­tronics.

ate notches and carefully place into the housing. Be sure that inter­nal sensor transmission wire does not cross the power supply lines
just installed.

• If using the Cable Gland be sure to properly tighten sealing grommet
before applying any tension on the cable, the cable gland provides
strain relief and environmental sealing.

• Tighten GC52 cover to maintain environmental rating.

• Connect to power source and receiver and power on to confirm cor­rect wiring (see Section 10 for more detail).

• Power Supply Requirements: Although the 4-20mA signal can travel
over long distances one of the most common problems is inadequate
power at the pressure transmitter due to the voltage drop across the
loop. Be sure to review table below to determine that 12-32V is get­ting to the pressure transmitter.

11.1 Filter

Set the filter before setting pressure display mode or linear (scaling)
display mode.

The filter is based on the moving average of the pressure data to de­crease display “bounce” and to smooth the analog output due to sys­tem pressure fluctuations at the user’s discretion.

Five selections: (0, 2, 4, 8, and 16 seconds).
If “0” is selected the filter is not applied.

This mode is used for display and analog output of the actual differ­ential pressure.

(1) Analog output

The analog output can be adjusted as follows; the zero point
(4mA) and the span point (20mA) can each be adjusted from –10
to 110%F.S. (URL)*.

(2) Pressure display

The pressure display has a display span between the zero point
and the span point as determined by the adjustment of zero and
span (see previous paragraph) and can display the range of –5
to 105%F.S.(URL). In addition, the decimal point position of the
pressure display is fixed for each pressure range.

point where zero (4mA) is 110%F.S. and the span point (20mA) can be adjusted to -10%F.S thus
reversing the output. In addition, through this adjustment zero and span can be adjusted accord­ingly for elevated tank levels.

11.3 Linear Display Mode (Re-scaling in arbitrary user defined units)

This mode is used for display / analog output of the scaling value
where the differential pressure is linearly converted to an arbitrary
physical quantity.

(1) Linear display

By setting the OFFSET to the minimum differential pressure P
and the FULL SCALE to the maximum differential pressure P2,
the linear display indicates the value on the line between the two
points (the maximum display span). The actual linear display
span depends on the setting of the zero point and span point of
the analog output as shown in (2) of the next page. It can display
the range of –5 to 105%F.S. of the linear display span.

11.4 Flow Measurement/Square Root Extraction Mode
Square Root Display Mode

Combining the sensing elements (orifice and pitot tube) with this prod­uct, the mode is used for the display of the momentary flow rate, inte­grated volume and for analog output corresponding to the momentary
flow rate.

(1) Momentary flow rate

Maximum display span from zero to the maximum momentary flow
rate. The Momentary flow rate display span depends on the set-
ting of the zero point and span point of the analog output as shown
in (2) analog output. It can display 0 to 105%F.S. of the momentary
flow rate display span. The scaling method can be performed only
by setting the maximum momentary flow rate and then generate
differential pressure using the following square root formula.

Momentary flow rate Dx is expressed by the square root formula
(a), and can be calculated only by measuring the generated differ­ential pressure Px (percent value over the differential pressure
range).

(%)

P

(a)

In addition, the coefficient k is determined by substituting the
maximum momentary flow rate Dm, which is measured from the
formula (a), and the then generated differential pressure Pm into
the formula (b).

(a)

• The differential pressure generated during the maximum momen-

tary flow rate can be set in the range of 25 to 100%F.S. of the differ­ential pressure range.

• The setting range for values of the maximum momentary flow rate

is 0 to 1999. Note: The decimal point can be set arbitrarily.

flow rate increases in the low flow domain of the differential pressure
flow meter, the domain (below the set value) will be forcedly indi­cated as zero by means of the low-cut for momentary flow rate.

Moreover, the analog output has a fixed value of 4mA at the zero
point. For setting of low-cut, input the percent value over the maximum
display span. Its range is 0 to 30%F.S. and the decimal point position
can be set up to one digit after decimal point as fixed point.

Setting of low-cut ==> Setting item 

(2) Analog output

The zero point (4mA) and span point (20mA) of analog output can
be set in the range of 0 to 110%F.S. of the maximum display span
(0 to maximum momentary flow rate). The span between the zero
point and the span point in this analog output is the momentary
flow rate display span.

(3) Integrated volume

• The units of integrated volume include two standards: Time

factor and flow rate volume factor.

Setting of integrated volume unit ==> Setting item 

• The number of digits of integrated volume display is a

maximum of 6 figures (999999); the display will return to 0 once
the maximum reading has been met.

• The zero reset of an integrated volume is executed by pressing S key
for more than 3 seconds and displaying "cLr" (clear) for 2 seconds.

20 , 21

• As backup in case of POWER OFF, the integrated volume value
is stored in the nonvolatile memory for every hour. After power re­turns, integration starts from the integrated volume value stored in
the memory.

20

• Integration is halted during the "FFF" display at the time of
differential pressure range OVER (Refer to paragraph 11.5 (1) ).

• The indicated value which is blinking is integrated during the
"blink" display at the time of momentary flow rate display span

OVER (Refer to paragraph 11.5 (2) ).

(4) Display switching method of momentary flow rate and

integrated volume

Display switching methods of momentary flow rate and integrated
volume include the automatic switching display method to dis­play them by turns at intervals of fixed time (1 to 10 seconds) and
the manual switching display method to change the display by
pressing (M) key.

䡵 Setting example 3: Standard unit for square root display mode

In the differential flow meter whose differential pressure generated at
maximum momentary flow rate of 120 is 32IW (80%F.S.) and which
uses a differential pressure range of 0 to 40IW, the scaling setting of
the momentary flow rate of standard unit and the setting of integrated
volume of the standard unit are as follows:

In this case, the low-cut is set as 15%F.S., the display switching
method is set as automatic, and the switching time is set as 5 seconds.

䡵 Setting example 4: Arbitrary unit of square root display mode

 Setting of momentary flow rate

In order to set a momentary flow rate to an “arbitrary unit,” the
momentary flow rate unit must be set as the arbitrary unit, and the
maximum momentary flow rate of the arbitrary unit and the then
generated differential pressure must be set.

23

 Setting of integrated volume

When a momentary flow rate unit is set as an arbitrary unit, the
integrated volume is also an arbitrary unit and the factor of the
two following points must be set:

• Setting of time factor (second, minute, hour)

• Setting of flow factor weight (1, 10, 100, 1000)

In the differential flow meter whose differential pressure generated
at maximum momentary flow rate of 1.000L/s is 16IW (80%F.S.)
and which uses a differential pressure range of 0 to 2.0 IW, the
setting of momentary flow rate of arbitrary unit and the setting of
integrated volume of the arbitrary unit (in order to display 1 per
count) are as follows: In this case, the low-cut is set as 10%F.S.
and the display switching method is set as manual.

(1) Range Over display

In the Measurement Mode, if the pressure is below –15% F.S.
(URL) “–FFF” will be displayed, and if it is more than 115%F.S.,
“FFF” will be displayed.

(2) Span Over display

When the user has adjusted the span of the device this case will
apply. The display range in each display mode is –5 to 105%F.S.
of the display span. When this range is exceeded, the value
of –5%F.S. or 105%F.S. will be held (depending upon whether
unit is below or above the span values) in a blinking state.

(3) Analog output

The analog output is linked with the display and is at 3.2mA when
the display span is at or exceeded –5%F.S. and at 20.8mA when
the display span is at or greater than 105%F.S.

In the measurement mode, the pressure connection (H, L) is open to the
atmosphere and T key is pressed for more than 3 seconds in order to
shift to zero adjustment mode (refer to section 11) for zero point adjust­ment of the differential pressure sensor.

• If the zero point adjustment is correctly performed, the message "AdJ"
will be displayed for 2 seconds, and the display will return to the meas­urement mode.

• If zero point correction is performed when the applied pressure is over
±10%F.S., the error message “E-0” will be displayed for 2 seconds, and
the display will return to the measurement mode without completing the
zero point adjustment.

CAUTION: Only perform the zero point correction when both the
H and L ports are open to the atmosphere. If done incorrectly the
accuracy of the device may be effected.

14.5 Loop Check

In each display mode, regardless of applied pressure, the loop check can
be changed by arbitrarily linking the display with the analog output using
the key operation. The display will show representative pressure readings
correlating to the 4-20mA signal.

䡲 Loop check method

(1) Remove the lid of this product.
(2) Shift to either the differential pressure, linear display or flow

measurement modes. (See Section 14). Use (M) button to scroll to
Loop Check function as indicated within Section 14.1, 14.2 or 14.3 re­spectively. The display and output (4mA) are at the zero point when
loop check starts.

(3) If the T is pressed, the display will increase along with the

output. By pressing S key, decrease will occur. Release the
key at the desired indication. For example, if the key is released at

25.0m, the display will stop and be held at analog output 12mA cor­responding to the indication, ref. example from section 14.2

䡲 Analog Output Check Terminals

When the front cover is removed, the analog output check terminals
(pad: CH+, CH–) are visible at the upper part of the display substrate.
The analog output can be checked during measurement mode or loop
check by applying a probe, such as a tester for current measurement,
onto the check terminal of the substrate, as shown in the following figure.
In addition, receivers are not affected by the tester's probes.
