PX5100

Version 6.03

(See Complete I&M Manual
for Further Detail)

Note: Press the button and release, do not “hold” the button

down (will reset the values).

D. Maximum Value “Capture”*: Press UP 쑿 button to display the

maximum value. The letter “H” will follow the reading indicating
this is the maximum value. Press the UP 쑿 button again to
return to Measurement Mode.

Note: If the button is held for 3 seconds it will go into zero

adjustment mode.

Minimum/Maximum Reset

The Minimum/Maximum values can be reset when in either
Minimum/ Maximum display by holding the DOWN 쑼 button for
more than three seconds, “clr” will appear on the display for two
seconds and the Minimum and Maximum values will be
removed.

Note: Values are maintained even if unit is powered OFF.

Hold reset

message

• When first using unit be sure to Reset values to clear values
in memory from the factory calibration process.

• Values are captured starting one minute after Reset, thus if
unit is powered OFF during the one minute the values during
that period will not be kept in memory.

3. Four functions available to the User via “Setting Mode”. To enter the
“Setting Mode” hold “M” key for more than 3 seconds. (See last page
for complete Setting Mode menu.)

A. Filter (Damping)

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 where 0=30ms (and in this
case the filter is not active), 2=60ms, 4=120ms, 8=240ms,
16=480ms, use 쑿쑼keys to change value.

B. Re-scaling in “psi” units: “Pressure Display Mode” allows for

zero (4mA) and span (20ma) adjustment of –10 to +110% Span
respectively.

Note: 1. See menu schematic on last page for detail.

2. Must be in “Pressure Display Mode” option within “Setting

Mode,” this is noted on the screen by

-

n non

Use 쑿쑼keys to move between “Pressure Display Mode” and
“Linear Display Mode” which is for re-scaling in “Arbitrary” units.

clr

Note: Holding the button for more than
3

seconds returns to display mode.

3. To adjust Output Zero Point (4mA) and Output Span Point
(20mA) must be in the functional area as noted below and
then adjustment is via 쑿쑼keys. The value shown is a
percentage of the pressure range (span) as noted on the
product label (ex. If product was supplied as a 0-100psi range
and the user desired the Output Zero Point to be “moved” from 0
psi to 50 psi then Output Zero Point would be 50.0 which is 50%.

function allows the user to establish a linear relationship from
the standard “psi” unit to any user defined unit.

Power supply requirements, 12-36Vdc, note installation recommenda­tions as follows:

erminal Strip: SMKDSP1.5/2-5.08 Phoenix contact

T

A. Cable Requirements

• Two core shielded cable

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

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

B. Wiring Instructions

• Do not run pressure transmitter cable / wires within the same

conduit as high voltage (line power) line to reduce the
potential for noise (interference). Use dedicated conduit on
PX5100 cables / wires for optimum results.

• Cable diameter, specified above, must be maintained when using the

Cable Gland termination to retain environmental ratings.

When connecting shield / drain wire, only connect one end which

•

should be at the received ground.

• Wire 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.

• Turn display over to expose terminal strip, make positive and negative

connections; insert wire equal to the recommended strip length
(0.25˝).

• After completing connections, align the retaining clips of the display

with the housing’s notches and carefully place into the housing. Be
sure that the internal sensor ribbon cable does not cross the power
supply lines just installed.

• Be sure to properly tighten the sealing grommet when using the

Cable Gland before applying tension to the cable; the cable gland
provides strain relief and environmental sealing.

• Tighten PX5100 cover to maintain environmental rating.

• Connect to power source and receiver, than apply power to confirm

correct wiring.

• Power Supply Requirements: Although the 4-20mA signal can travel

over long distances, a very common issue to arise involves
inadequate power at the pressure transmitter – this results in voltage
drop across the loop. Be sure to review the accompanying table to
determine whether the 12-36Vdc has been received at the pressure
transmitter.
