I Differential Pressure Transmitter models that do not

ave a display would be to use a Model A-435-A remote display tool which can plug

nto the connector shown in Figure 1. The remote display tool has two buttons that

function identically to the buttons on the PCB.

CALIBRATION

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. The display will read ZEro and

then sequence back to the home display. If the current reading is not close enough

to zero (±2%), the operation will fail and FAIL will be displayed.

PAN Calibration

he span calibration can be adjusted only after setting the zero adjustment. It must

e 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. The display will read SPAn and then sequence back

o the home display. If the span calibration is attempted before adjusting the zero

calibration, the FAIL error message will flash on the display. For bi-directional

ranges, separate spans can be performed for positive and negative sides of the

range. A failure will also occur if the span operation is performed too closely to the

ero point pressure.

isplay 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.

-rErr = Negative display value too low to display.

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.

The level of access to the programming menus and the calibration is limited based

on the security level. The above table details the level of access for each security

level.

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.

ode Selection / Digital Dampening Menu

rom the home display, pressing the span and zero button simultaneously for 3

econds will access the Menu Security Level. If the level is set to 0 or 1, pressing and

olding the span button for 3 seconds a second time will access the Mode Selection

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

button will cycle to Velocity and Flow.

nce the desired Mode is displayed, pressing and holding the span button for three

econds will save the selected mode and display the digital dampening or averaging

arameter. This parameter stabilizes the output and the display by averaging the

eadings. 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.

RESSURE MODE

aximum 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

etting the range, the POH parameter can be set to off.

ELOCITY 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

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

an be adjusted between 0.001 to 9.999. The K-Factor can be adjusted by pressing

he 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.

Area Adjustment

For Flow applications, the area is multiplied by the velocity to determine the

volumetric air flow. The area will be listed in either feet or meters depending on the

dip switch settings. The units will be indicated on the display at the time of

adjustment.The area 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 flow or a pressure. After adjusting the

Area parameter, the display will indicate if the adjustment is set for pressure or flow.

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.

Security Update / Save Changes Menu

The Security Update Menu allows the security level to be set either higher or lower

than the current security level setting. This security level will be displayed the next

time the Menus are accessed from the home screen. Pressing the zero button cycles

through the security levels. Pressing and holding the span button for three seconds

accepts the new security level and gives the option to save all the menu changes.

ressing the zero button will toggle between yes and no. Yes will save the changes

ade to all menu items and no will discard all the changes made to all menu items.

f the display is set to yes, pressing and holding the span will save the menu items

nd return the display to the Home Position.

FACTORY DEFAULT PROCEDURE

n order to reset all of the menu settings back to their factory programmed values,

ress and hold both the span and zero buttons simultaneously for 10 seconds until

ACt is displayed on the LCD. Upon releasing the buttons, the unit will be factory

efaulted. Since resetting the transmitter will wipe out all changes, it is necessary to

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

APPENDIX I

Air Velocity / Air Flow Calculations

Velocity is calculated using the below equation:

elocity(fpm) = K-Factor x 4004.4 x √(Diff. Press. (in of w.c.)

Velocity in m/s is then calculated from the equation:

Velocity(m/s) = Velocity(fpm) x 0.00508

Flow is calculated using the below equation:

Flow(cfm) = Area(Ft

) x K-Factor x 4004.4 x √(Diff. Press. (in of w.c.)

Flow (m

/h) = Flow (cfm) x 1.6992
