Installation- & Operation manual

[Doc.id: mi-306gb_141103]

NOTE !

Read through the entire manual before you begin installation and programming.

APPLICATION

MF-PFTT is a microprocessor controlled transmitter/ controller for measurement and control of differential pressure, ﬂ ow or temperature. With an external temperature sensor, the ﬂ ow measurement can be compensated for variations in the temperature. With an optional purging unit, PU3, the connected ﬂ ow sensor can automatically be purged with set intervals. With the four keys on the front panel it is possible to access all functions, make settings and scaling the output signal. The double row, 2x16 character, LCD with backlight displays functions and values.

MOUNTING

MF-PFTT is designed for wall mounting but can be ﬁ tted with an optional frame kit, MFM-PANEL, for recessed mounting on wall or through a cabinet door. MF-PFTT is screwed to the wall using four screws, max ø 4mm. Location of screw holes are shown on the backside of the enclosure. Unscrew the lid and use the bottom screws to temporarily ﬁ x the lid on the upper edge of the enclosure during installation. See ﬁ gure.

OUTPUT SIGNAL

MF-PFTT has two analogue output signals which can be used for pressure, ﬂ ow, temperature and control signal. Each output has three terminals, one for Volt DC, one for mA DC and one common zero. With activated purging function, the purging unit is connected to output 1 (mA) and the parameter (P10) is hidden in the parameter list. If the unit is ﬁ tted with built-in automatic zero-setting module, it is connected to output 2 (mA) and the parameter (P13) is hidden in the parameter list.

ALARM

MF-PFTT has two alarms, each independent of the other. The alarm is acoustic with beeper and visual with LED indication for pressure, ﬂ ow or temperature. High or low alarm level and manual or automatic reset.

START MENU

When the transmitter is connected to supply voltage, a start menu is displayed. Using the arrow-keys it is possible to scroll through the different available start menus. To have the unit always displaying the same start menu, it can be selected and

programmed in parameter group System settings. By pressing the ESC-key when other menus are

displayed the selected start menu is displayed

PROGRAMMING

Push the PGM-key until “PROGRAM-MENU” is displayed. Release the PGM-key and the ﬁ rst parameter

MF-PFTT has 2 output signals which can be set to either 0..10 Volt, 2..10 Volt, 0..20 mA or 4..20 mA. Both Volt and mA are simultaneously available for both outputs.

• P08/P11 Source, is used to select which measuring

value/signal (source) to direct as output signal. ‘dP’ is the pressure signal, ‘FLOW’ is the ﬂ ow signal, ‘CTRL’ is the control signal from the PI-controller and ‘TEMP’ is the actual temperature from the temperature sensor.

• P09/P12 Signal V is used to switch between 0..10

Volt and 2..10 Volt output signal.

• P10/P13 Signal mA is used to switch between

0..20 mA and 4..20 mA output signal.

With activated purging function, the purging unit is connected to output 1 (mA) and the parameter (P10) is hidden in the parameter list. If the unit is ﬁ tted with built-in automatic zero-setting module, it is connected to output 2 (mA) and the parameter (P13) is hidden in the parameter list.

5. PRESSURE

Settings for pressure measurement

No Lead text Min Max Default

• P15/P16 MinCal[Pa] / MaxCal[Pa],

The MF-PFTT is factory calibrated for a speciﬁ c range. The range is written on a label located on the right side of the enclosure. The calibration is

always in Pascal (Pa). MinCal and MaxCal is the

calibrated pressure range in Pa. These values are notes and not possible to change.

• P17 Unit dP, Select in which unit to display the

pressure. The alternatives are Pa, mbar or iwc (inch water column).

Page 4 of 10 [© AB Micatrone, mi-306gb_141103]

• P18 Decimals, Number of decimals to show for the

pressure value. When using Pa as unit it is recommended not to use decimals. In case any set value is above 32767 regardless of where the decimal point is placed the adjustment is not carried out.

E.g. If Set Point = 5000 and one decimal is se-

lected, the adjustment will not work since the value 5000,0 is greater than the allowed max value of 3276,7. Of the same reason, 500,0 cannot be adjusted to 500,00.

• P19/P20 Min range / Max range

When programming a new unit, min and max limits

in the new unit are displayed in parameter Min range and Max range. These values are notes and

not possible to change.

• P21 Min out, Lower limit for scaling the output

signal is set in pressure units, e.g. 10 Pa will result at 10 Pa pressure the min output signal of, 0/2 V resp. 0/4 mA.

• P22 Max out, Higher limit for scaling the output

signal is set in pressure units, e.g. 90 Pa will result at 90 Pa pressure the max output signal of 10 V resp. 20 mA.

• P23 Sign dP, If the transmitter is without zero

crossing, the MF-PFTT will indicate a negative pressure similar to positive pressure (i.e. Without

negative sign). When programming Sign dP =

‘NEG’ a negative sign (-) is shown in front of the current value.

• P81 AutoZero, Using the optional built-in solenoid

valve, automatic zero adjustment can be set. The time between adjustment can be set between 0,1 and 60 hours. During this process, the displayed values and the output signals are halted. After the zero adjustment is done in approx. 15 seconds, the transmitter restore to normal operation. Zero adjustment can also be carried out manually according to instructions on page 8.

To change the range for the output signal, the Min out and Max out are programmed. Programmed values

must be in the selected unit (Pa, mbar, iwc). When scaling, be aware that the accuracy is always in percent of the factory calibrated pressure range.

6. FLOW

To measure and control the ﬂ ow or velocity it is necessary to connect the transmitter to ﬂ ow sensors with a known formula and k-factor.

• P25 Decimals, Number of decimals to show for the

ﬂ ow value. In case any set value is above 32767 regardless of where the decimal point is placed the adjustment is not carried out.

E.g. if Max Flow = 5000 and one decimal is se-

lected, the adjustment will not work since the value 5000,0 is greater than the allowed max value of 3276,7. Of the same reason, 500,0 cannot be adjusted to 500,00.

• P26 Max ﬂ ow, set the ﬂ ow that correspond to the

pressure range on the MF-PFTT.

• P27 Scale ﬂ w, set the ﬂ ow for max output signal,

10 V resp. 20 mA.

• P28 Set ﬂ ow, Programme this parameter if adjust-

ing the displayed ﬂ ow is necessary. Programme the current ﬂ ow using a reference ﬂ ow measure-

ment. Max ﬂ ow is re-scaled to correspond with the

reference measurement. If the unit is connected to a computer system or similar, the receiving system

should also be programmed if the Scale ﬂ w value is higher than the new value of Max ﬂ ow. NOTE! Programming must be performed at the

same time as when the reference value is meas-

ured (The PGM-key is pressed for the last digit and

the value is stored).

• P29 Compens, with a connected temperature

sensor, the measuring value can be recalculated from the standard temperature of 20°C to a ﬂ ow at actual temperature, ‘ ACTUAL’, -30...+600°C or to a ﬂ ow at normal condition 0°C, ‘NORMAL 0’.

The basic ﬂ ow calculation used is made with √dP. To have the display and the output corresponding to the actual ﬂ ow or velocity in the selected unit it is necessary to make some calculations. Different manu factors of ﬂ ow measurement devices have different calculation, but common for all is √dP. Use the actual formula to calculate the max ﬂ ow for the factory calibrated measure range. The calculated ﬂ ow or velocity is then programmed under Max ﬂ ow in the selected unit. E.g. 5,0 m

/s. It

is possible to scale the ﬂ ow range under Scale ﬂ w.

When scaling the ﬂ ow, note that the accuracy depends

on the “Max ﬂ ow” range. Scale ﬂ w must always be set to the same or a lower value than Max ﬂ ow.

E.g. 3,5 m3/s = 10 VDC. The output signal is linear to the ﬂ ow or velocity.

MF-PFTT has an alarm with two, each independent, alarm limits. The alarm is acoustic with buzzer and visual with LED (light emitting diode). Normal state is indicated with green LED and alarm state with red ﬂ ashing LED on the lid. The acoustic alarm can be disabled for each alarm limit. Red LED is activated by the ﬁ rst alarm state that occur. At the alarm limit, the red LED is lit and after set time delay it begin to ﬂ ash. The display show which of the alarm limits that triggered the alarm.

• P33/P40 Mode, select if the alarm should be trig-

gered for high or low level. Programme as ‘OFF’ to deactivate monitoring.

• P34/P41 Source, Choose which measuring value

to be monitored. ‘dP’ = pressure, ‘FLOW’ = ﬂ ow ‘TEMP’ = temperature.

• P35/P42 Limit, set at which level the alarm to be

triggered.

• P36/P43 Delay [s], set time delay before alarm

state occur.

• P37/P44 Reset, ‘MANUAL’ if the alarm should be

reset manually by pressing the ESC-key or ‘AUTO’

if the alarm state should return automatically to normal state when the level is back to normal.

• P38/P45 Beeper, ‘OFF’ disable the acoustic alarm.

‘ON’ if alarm state should sound.

• P39/P46 Mute time, is used to silence (mute) the

alarm for a set time in seconds when the ESC-

key is pressed. If the time is set to ‘0’, the alarm is mute until the alarm is reset and a new alarm state occur.

MF-PFTT has a PI-controller specially made for pressure and ﬂ ow control. The controller could be programmed as a standard PIcontroller, but in most of the applications together with pressure and ﬂ ow control we recommend to program it as an integral controller without P-band. There are two programmable I-times. Outside a desired limit on both sides of the set point it is possible to have a shorter I-time and inside the limits a longer I-time. The PI-control signal is directed to a desired

output in parameter group Output 1 or Output 2.

• P47 Mode, ‘ON’ activates Pi-controller, ‘OFF’ dis-

able the controller.

• P48 Source, select which measuring value to

control. ‘dP’ = pressure, ‘FLOW’ = ﬂ ow, ‘TEMP’ = temperature.

• P50 Temp 1, see chapter “Control applications”.

• P51 SP 1, see chapter “Control applications”.

• P52 Temp 2, see chapter “Control applications”.

• P54 SPC Type, see chapter “Control applications”.

Page 6 of 10 [© AB Micatrone, mi-306gb_141103]

• P58 NZ [%], select desired neutral zone, normally

1..5%. Half zone above and half below set point value. Set in percent of the measuring range.

• P59 P-band [%], normally not used for pressure or

ﬂ ow control, default 0%. If P-band is programmed to 0 % the P-function is disabled and the I-time is calculated for a P-band of 100%.

• P60 I-time[s], set suitable I-time, normal 10s.

• P61 BZ [%], Break zone, used when you want to

reduce the control speed when surrounding the set point.

• P62 I-time BZ, set I-time inside the break zone. En-

ter a longer I-time for a stable control when close to the neutral zone.

• P79 Min ﬂ ow, see chapter “Control applications”.

• P80 Max ﬂ ow, see chapter “Control applications”.

• P63 Output, direction of the control output signal.

Normally ‘REVERSE’ (if the pressure or ﬂ ow is above set point, the output signal will decrease).

• P64 Min output, set a lower limit for the control

output signal in %.

• P65 Max output, set a higher limit for the control

output signal in %.

Control applications

The controlled unit can be selected as pressure, ﬂ ow or temperature.

Fixed pressure or ﬂ ow control:

Select pressure or ﬂ ow in parameter 48, Source, and set desired set point in parameter 51, SP 1.

Temperature controlled pressure or ﬂ ow control:

Select parameter 48, Source, as ‘dP’ or ‘FLOW’. Set parameter 54, SPC Type to ‘TEMP’.

Programme the lowest pressure or ﬂ ow in parameter

51, SP 1, at set temperature in parameter 50, Temp 1.

Programme the highest pressure or ﬂ ow in parameter

53, SP 2, at set temperature in parameter 52, Temp 2.

Temperature control (VAV):

Select parameter 48, Source, as ‘TEMP’. Set parameter 54, SPC Type, to ‘OFF’ and programme a desired temperature in parameter 51, SP 1, together with min and max ﬂ ow in parameter 79, Min ﬂ ow and parameter 80, Max ﬂ ow.

The ﬂ ow control point will ﬂ oat between the programmed values in parameter 79 and 80 to maintain the set temperature.

I-time

When programming as an I-controller there are two possibilities.

• The same I-time over the full range. Normally used. Program BZ = 000 and I-time BZ = 000. The I-time should normally be longer than the time for the damper motor etc. to go from min to max.

• Shifting between two I-times. The reason for working with two I-times is often that outside a set pressure or ﬂ ow limit you want to have a fast response and inside a slow response (see ﬁ gure).

BZ: limit for switching I-time. BZ is in % of the scaled pressure or ﬂ ow range. The set break zone, BZ, is counted from the neutral zone, NZ, higher and lower

limit. The set value is on each side of the neutral zone and moves with any changes in the neutral zone. If the control output is not entering a stable position, increase the I-time, you could also try to increase the neutral zone.

Manual operation

Return to the start menu and select the display option where output signal for PI-controller together with pressure, ﬂ ow or temperature is indicated. Which one that is displayed is determined by what the PI controller is programmed for.

“Flow / dP” “AUTO 50.00 %”

Press PGM, ‘AUTO’ changes to ‘HAND’ and the output

signal can be set in % using the arrow keys.

Return to position ‘AUTO’ by pressing the PGM-key.

To display the programmed start menu, press the

ESC-key.

The display showing the text “PI-” in front of ‘HAND’ or ‘AUTO’ is not possible to use for manual operation.

CODE LOCK PROTECTION

The code lock is used to protect against an authorized programming. A four-digit code must be entered to access the program menu and the functions menu. It is still possible to read measuring values and operating state without entering the access code. At delivery, the code is set to ‘0000’, unless otherwise agreed on. When the code is set to ‘0000’, the code lock is inactivated and no protection against an authorized programming is present.

Activation

To activate the code lock, a 4-digit code must be

programmed in parameter P05 Access code which is found in parameter group System settings. The code

can not be ‘0000’, since this code is used to deactivate the function. When a code has been programmed and saved, the next time it will be necessary to enter the code to access the program menu and the functions menu.

Deactivating

The code lock can only by deactivated in the program menu and therefore the access code must be available to deactivate the code lock. Set the parameter P05

Access code to ‘0000’. The parameter is found in the parameter group System settings.

Contact Micatrone if the code has been lost!

Entering the code

To access the program menu or functions menu it is necessary to enter the access code. Example:

1. Press the PGM-key to open the program menu. Press the PGM-key until “PROGRAM- MENU” is

displayed.

2. Release the PGM-key. Following text is displayed

if key code is activated: “ENTER CODE:” and “0***”.

3. The ﬁ rst digit of the access code can be entered

using the arrow keys. When ready press the PGM-

key to continue with the next digit. Repeat until all digits are entered.

4. When the 4 digits are entered, press the PGM-key

a ﬁ nal time. The entered code is now compared with the programmed code in parameter P05

Access code. If the codes match, the program

menu is displayed. The program menu is available

until it has been exited using the ESC-key.

5. If the entered access code is incorrect, the text “INVALID CODE” is displayed during 2 seconds. Restart from point 1.

6. By pressing the ESC-key, the entering code

operation is cancelled and the default start menu is displayed.

Calibration of MF-PFTT

MF-PFTT can be re calibrated against a pressure reference.

1. Keep PGM and ESC pressed until following text

is displayed: “FUNCTIONS-MENU”.

2. Scroll using the arrow keys until “Calibration” is displayed.

3. Press PGM. ‘Input’ is shown.

4. Press PGM. ‘Cal dP’ is shown.

5. Press PGM. The ﬁ rst calibration point is shown.

Example: MF-PFTT (-50..50 Pa) Pnt 1(5) = -50

6. Connect shown pressure. In this case, 50 Pa, to the pressure connection marked negative [-].

7. Press the PGM-key and the MF-PFTT will

start to measure the ﬁ rst calibration point (9 measurements).

8. Press the PGM-key to continue with the second calibration point, ESC aborts the calibration.

9. Proceed with all ﬁ ve calibration points and be careful to connect to the correct pressure connection.

10. When all calibration points are done, following text is shown: “PGM=OK/ESC=ABORT”

11. The PGM-key will conﬁ rm the calibration and

store the new calibration values.

12. The ESC-key will abort and cancel the calibration. Press repeatedly on the ESC-key to return to the

start menu again.

Note! The pressure reference should comply with the

demand of desired accuracy in the measurement.
