The Series MS2 Magnesense® II Differential Pressure Transmitter combines the
proven stable Piezo sensing technology of our original Series MS with additional
features to reduce installation time and simplify ordering. In this second generation

transmitter, we have added additional eld selectable pressure ranges so that each

model can have four selectable ranges along with four additional bidirectional ranges.
When using the pluggable integral display or the portable remote display tool, both
Metric and English engineering units can be selected via on board dip switches. Dual
current and voltage outputs allow users to simultaneously take either a current or

voltage output to their building controller and have a local test circuit for verication of

the output reading. The voltage output can be selected to be either 0 to 5 VDC or 0 to
10 VDC, while the current is always 4 to 20 mA. Both the current and voltage output
can also be inverted. Alternatively, the MS2 can be ordered with either a BACnet
or MODBUS
chained together.

Like the original Series MS, the second generation transmitter can be used as a linear
pressure output or a linear velocity output with the square root extraction done in
the transmitter. Additional parameters have been included to expand the square root

capability to include ow measurements.

BACnet
nodes in any segment to 32. Therefore, the transceiver may be rated at one unit load.
Fractional loads are also acceptable. The MS2 accounts as an eighth of a load on the
MSTP network.

INSTALLATION
Surface Mount:

The transmitter should be mounted on a vertical surface with the connections directed
down to prevent moisture from entering either the pressure ports or the electrical cable
entry. The diaphragm must be vertical to minimize gravity effects on the diaphragm.

Attach the mounting ange to a at surface using three #8 x 1/2˝ pan head sheet metal

screws. Do not over tighten.

Choose a power supply with a voltage and current rating sufcient to meet the power
specications under all operating conditions. If the supply is unregulated, make sure

that the output voltage remains within the required voltage range under all power line
conditions. Ripple on the supply should not exceed 100 mV.

AC/DC Jumper Selection

NOTICE

The jumper is factory set to AC. If DC power is applied while
the jumper is set to AC, no damage will occur. However, the

accuracy of the unit may temporarily be affected.

CAUTION

Powering the unit with AC power while the jumper is set to DC
may permanently damage the transmitter.

Refer to Figure 1 for the location of the AC / DC jumper. Place the shorting jumper
across either the two pins marked AC or the two pins marked DC.

The range of appropriate receiver load resistances (RL) for the power supply voltage

available is given by the formula listed below. Shielded 2-wire cable is recommended
for control loop wiring. Ground the shield at the power supply end only.

NOTICE

The receiver may be connected to either the negative or positive

side of the loop, whichever is most convenient. Should polarity
of the transmitter or receiver be inadvertently reversed, the loop will not function
properly but no damage will be done to the transmitter.

The maximum length of connecting wire between the transmitter and the receiver is
a function of wire size and receiver resistance. That portion of the total current loop
resistance represented by the resistance of the connecting wires themselves should

not exceed 10% of the receiver resistance. For extremely long runs (over 1,000 feet),

it is desirable to select receivers with lower resistances in order to keep the size and
cost of the connecting leads as low as possible. In installations where the connecting
run is no more than 100 feet, connecting lead wire as small as No. 22 ga. can be used.

are labeled underneath the terminal block on the circuit board. Polarity is indicated by
PWR, COM, and +VOUT. When connecting using a DC power source, make sure the
AC/DC selection jumper is set for DC. If the polarity of the transmitter is inadvertently
reversed, the unit will not function properly, but no damage will be done to the
transmitter. When connecting to an AC power source, make sure the AC/DC selection
jumper is set for AC. Either lead of the supply power may be connected to PWR and
COM without affecting the operation of the transmitter or damage to the transmitter.

The minimum receiver load is 1K Ω. The resistance due to the wire should be low

compared to the receiver load resistance. While the voltage at the terminal block

remains unchanged with a 10 mA current ow, resistive losses in the wiring do cause

errors in the voltage delivered to the receiver. For a 1% accurate gauge, the resistance
of the wires should be less than 0.1% of the value of the receiver load resistance. This

will keep the error caused by the current ow below 0.1%.

The output across +VOUT and COM will be either 0 to 5 V, 0 to 10 V, or the inverse
depending on the dip switch setting. See Dip Switch Setting Section for more

For the current output, the maximum allowable loop resistance (wiring + receiver
resistance) is dependent on the power supply. The maximum loop voltage drop must

not reduce the transmitter voltage below 17 V. The maximum loop resistance can be
calculated using the following equation:

R

MAX = (VPS – 17.0) / 0.02 Where VPS is the power supply voltage

The equation uses 17.0 instead of 10.0 used in current only equation. This represents

the minimum voltage supply which is higher on the simultaneous output conguration

due to the requirements of the voltage outputs.

Shielded 4-wire cable is recommended for control loop wiring. Ground the shield
at the power supply end only. Should the polarity of the transmitter or receiver be
inadvertently reversed, the unit will not function properly, but no damage will be done
to the transmitter.

DIP SWITCH SETTINGS

DIP Switches can be located next to the terminal block as shown in Figure 5. A small
screw driver or pen can be used to change the position of the switches.

WARNING

All power should be turned off to the transmitter before adjusting
the dip switch settings to avoid electrical shock.

Setting for Unidirectional or Bidirectional

The Models MS2-X101 and MS2-X102 models are unidirectional only. The Bidirectional
models MS2-X103, MS2-X111 and MS2-X112 can be changed to measure pressure in
one direction at a reduced accuracy by changing the setting of DIP Switch 3.

• When the switch is in the ON direction, the transmitter will be set for Unidirectional

and will be 0 based (i.e. 0 to 5 in w.c.).

• When the switch is in the OFF position, the transmitter will be set for Bidirectional

and will be ± the maximum of the selected range (i.e. ±5 in w.c.).

• For unidirectional units only, switch has no effect and unit will remain in unidirectional
mode.

Setting the Engineering Units

Magnesense

Setting the Output Voltage Range

Voltage output can be either 0 to 10 V or 0 to 5 V depending on the position of DIP
Switch 6.

• When the switch is in the ON position, the output will be 0 to 10 V

• When the switch is in the OFF position, the output will be 0 to 5 V

Setting the Input / Output Action

The output will either directly or indirectly follow the input based on the position of DIP
Switch 7.

• When the switch is in the ON position, the output directly follows the input (i.e. output
increases as the input increases)

• When the switch is in the OFF position, the output acts in reverse of the input (i.e.
output decreases as the input increases)

Another option for models that do not have a display would be to use a Model A-435-A
remote display tool which can plug into the connector shown in Figure 7. The remote
display tool has two buttons that function identically to the buttons on the PCB.

CALIBRATION

NOTICE

There is a 5 second delay from the time the zero or span

calibration buttons is released until the time that the change in
calibration takes place. This delay is used to prevent stress related offsets on the
lower ranges.

NOTICE

The security level that is set in the Programming Menu Section

of the manual will determine which calibrations, if any, may be
adjusted by the user.

Zero Calibration

The zero calibration can be set by applying zero pressure to both the pressure ports
and pressing the zero button for 3 seconds. If either the remote or local LCD is present,
the display will read ZEro and then sequence back to the home display.

SPAN Calibration

The span calibration can be adjusted only after setting the zero adjustment. It must
be completed within 5 minutes of the last zero calibration. The span calibration button
will be ignored until the zero calibration is completed. Apply pressure to the ports of

the transmitter that is associated with the maximum output of the transmitter (20 mA,
5 V, or 10 V depending on output being used). Press and hold the span button for 3

seconds. If either the remote or local LCD is present, the display will read SPAn and
then sequence back to the home display. If the span calibration is attempted before
adjusting the zero calibration, the FAIL error message will ash on the display. On bi-
directional models, separate spans can be performed on the positive and negative
sides of the range.

LCD DISPLAY

The Magnesense

®

II can be ordered with an optional, integral LCD. If the display is

not needed for normal operation, the transmitter can be ordered without the LCD.

An A-MS2-LCD eld upgradeable display is available. It comes with a housing cover

with the overlay cut out for the display. The display will plug into the pins as shown in
Figure 6.

Figure 7

Display Error Messages

ovEr = The applied pressure is greater than the maximum span value causing an Over
Range Error.
UndEr = The applied pressure is less than the minimum span value causing an Under
Range Error.
FAiL = When the span or zero buttons are pressed, the pressure value is out of the
range to allow a correct setting. This may be due to a sensor failure or incorrect
pressure being applied.
Err1 = The sensor is damaged.

PROGRAMMING MENUS

Home Menu

During normal operation, the display will be in the Home Menu and will display the
current measured pressure and the engineering units.

Menu Access Security

While in the Home Menu, press and hold the Zero and Span buttons simultaneously
until SECUr appears on the display in order to access the other programming menus.
Upon releasing the buttons, the display will indicate the current security level.

If the current security level is the security level desired (i.e. Security Level 0), press

and hold the span button for three seconds to enter the Pressure, Velocity, or Air Flow
Menu.

If the security level is not the desired level, the security level can be changed
temporarily to a lower security level or permanently to a higher level of security by
pressing the zero button. A security code will be shown on the display and it can be
changed to one of the codes listed in the below table. The span button chooses which
digit and the zero button increments the value of that digit. Pressing and holding the
span button will store the value.

Mode Selection / Digital Dampening Menu

From the home display, pressing the span and zero button simultaneously for 3
seconds will access the Menu Security Level. If the level is set to 0 or 1, pressing and
holding the span button for 3 seconds a second time will access the Mode Selection

Menu. The display will default to Pressure when rst powered up. Pressing the zero

button will cycle to Velocity and Flow.

FACTORY DEFAULT PROCEDURE

In order to reset all of the menu settings back to their factory programmed values,
press and hold both the span and zero buttons simultaneously for 10 seconds until
FACt is displayed on the LCD. Upon releasing the buttons, the unit will be factory
defaulted. Since resetting the transmitter will wipe out all changes, it is necessary to

zero (and possibly span) the transmitter before taking measurements.

Once the desired Mode is displayed, pressing and holding the span button for three
seconds will save the selected mode and display the digital dampening or averaging
parameter. This parameter stabilizes the output and the display by averaging the
readings. There are 2.5 readings taken each second and the user can select the
number of seconds that they would like to average up to 240 seconds. The display and
the output will continue to update at a rate of 2.5 updates per second, but the moving
average is used for these updates.

PRESSURE MODE
Maximum Output Adjustment

If the Pressure Mode was selected, pressing and holding the span after adjusting the
digital dampening will enter the Pressure Mode. In this menu, the maximum output

pressure (POH) can be adjusted to any pressure between the lowest dip switch range

to the highest dip switch range. If the dip switch settings are preferred over manually
setting the range, the POH parameter can be set to off.

VELOCITY MODE
K-Factor Adjustment

If the Velocity Mode was selected, pressing and holding the span after adjusting the
digital dampening will enter the Velocity Mode and the transmitter will display the
engineering unit that has been selected by the dip switch. Pressing and holding the

span button for three seconds will enter the K – Factor adjustment. The K – Factor can

be adjusted between 0.001 to 9.999. The K-Factor can be adjusted by pressing the
span button to select the digit and pressing the zero button to increment the value of the
digit. Pressing and holding the span button for three seconds will enter the Maximum
Output Adjustment parameter.

Maximum Output Adjustment

The maximum output can be equivalent to a velocity or a pressure. After adjusting
the K-Factor, the display will indicate if the adjustment is set for pressure or velocity.
Pressing the zero button will toggle between the selections. Pressing and holding the
span button for three seconds will enter the maximum output adjustment. The maximum
output can be adjusted by pressing the span button to select the digit and pressing the
zero button to increment the value of the digit. Pressing and holding the span button for
three seconds will save this value and go to the Security Update Menu.

FLOW MODE
K-Factor Adjustment

If the Flow Mode was selected, pressing and holding the span after adjusting the digital
dampening will enter the Flow Mode and the transmitter will display the engineering unit
that has been selected by the dip switch. Pressing and holding the span button for three

seconds will enter the K – Factor adjustment. The K – Factor can be adjusted between

0.001 to 9.999. The K-Factor can be adjusted by pressing the span button to select
the digit and pressing the zero button to increment the value of the digit. Pressing and
holding the span button for three seconds will enter the Area Adjustment parameter.
