1. Brief description

The panel meter M2-1F can evaluate pulses in many different ways and show the result in the 5-digit LEDdisplay. Available options are: frequency coverage with optional filters, summate of pulses or display values via the time, detection of a rotational speed or collection of a position via an incremental encoder. The results can be monitored via alarm conditions and can be displayed onto the optional switching point.

Furthermore the results can be freely scaled on an optional analog output and relayed to a control system.

The device can be operated directly by Namur sensors, 3-wire sensors, switching/slider contacts, incremental encoders (HTL-/TTL-output) or TTL-signals.

Via the 4 navigation keys on the front, the device can be adjusted onto different kind of applications and later on different functions of the device can be controlled. The adjustment is also possible via the PC-

Software PM-TOOL with a special connecting cable. With an individual code, the created parameterisation can be protected against changes by the user.

Numerous applications can be realised with this device, like e.g. tachometer, revolution counter, flowmeter, dosing equipment, filling capacity meter, baking time meter of a baking oven, flying knife, position evaluation, position surveillance, flow rate surveillance, acoustic discharge measurements and so on. By use of the integrated, configurable functions like permanent min/max-recording, averaging, frequency filter, setpoint setting, threshold value recording via alarm system, 30-points-linearisation, mathematic charging and many more, you receive an universal applicable modern system for your demands in measuring and control technique.

4. Function and operation description

Operation

The operation is divided into three different levels.

Menu level (delivery status)

This level is for the standard settings of the device. Only menu items which are sufficent to set the device into operation are displayed. To get into the professional level, run through the menu level and parameterise

“prof“ under menu item RUN.

Menu group level (complete function volume)

Suited for complex applications as e.g. linkage of alarms, setpoint treatment, totaliser function etc. In this level function groups which allow an extended parameterisation of the standard settings are availabe. To leave the menu group level, run through this level and parameterise „uloc„ under menu item RUN.

Parameterisation level:

Parameter deposited in the menu item can be parameterised here. Functions, that can be changed or adjusted, are always signalised by a flashing of the display. Settings that are made in the parameterisation level are confirmed with [P] and thus safed. By pressing the „zero-key“ it leads to a break-off of the value input and to a change into the menu level. All adjustments are safed automatically by the device and changes into operating mode, if no further key operation is done within the next 10 seconds.

4. Function and operation description

4.1. Parameterisation software PM-TOOL:

Part of the PM-TOOL are the software on CD and an USB-cable with device adapter. The connection is done via a 4-pole micromatch-plug on the back side of the device, to the PC-side the connection ist done via an USB plug.

System requirements: PC incl. USB interface

Software: Windows XP, Windows VISTA

With this tool the device configuration can be generated, omitted and safed on the PC. The parameters can be changed via the easy to handle program surface, whereat the operating mode and the possible selection options can be preset by the program.

CAUTION!

During parameterisation with connected measuring signal, make sure that the measuring signal has no mass supply to the programming plug. The programming adapter is galvanic not isolated and directly connected with the PC. Via polarity of the input signal, a current can discharge via the adapter and destroy the device as well as other connected components!

5. Setting up the device

5. Setting up the device

5.1. Switching-on

Once the installation is complete, start the device by applying the voltage supply. Before, check once again that all electrical connections are correct.

Starting sequence

For 1 second during the switching-on process, the segment test (8 8 8 8 8) is displayed, followed by an indication of the software type and, after that, also for 1 second, the software version. After the starting sequence, the device switches to operation/display mode.

5.2. Standard parameterisation: (flat operation level)

To parameterize the display, press the [P] key in operating mode for 1 second. The display then changes to the menu level with the first menu item TYPE.

Menu level Parameterisation level

Selection of the input signal, TYPE:

Default: frequ

If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range needs to be preset under rAnGE and is adjusted by application of the final value / initial value. If FrEqU

(Factory calibration) is preferred, the final value needs to be entered under End and the final frequency needs to be entered under EndA. Under OFFS the initial value needs to be entered and under OFFSA the initial frequency. There is no application of the measuring signal. Rotar is the rotation in r.p.m. up to 10 kHz input frequency. Posit is the position recognition per incremental encoder. Confirm the selection with [P] and the display switches back to menu level.

Adjustment of pulses per rotation, ppr:

Default: 1

This parameter is only important if type=rotar or =Posit have been selected. Generally it shows the number of pulses per rotation.

Setting end value of the measuring range, END:

Default: 100e3

9.9999 Hz 99.999 Hz 999.99 Hz 9.9999 kHz

99.999 kHz

999.99 kHz

Choose between six different frequency ranges. Confirm the selection with [P] and the display switches back to menu level.

5. Setting up the device

Menu level Parameterisation level

Setting the final value of the measuring range, END:

Default: 10000

Set the final value from the smallest to the highest digit with [▲] [▼] and confirm each digit with [P]. A minus sign can only be parameterized on the highest value digit. After the last digit, the display switches back to the menu level. If Sens was selected as input option, you can only select between noca and cal. With noca, only the previously set display value is taken over, and with cal, the device takes over both the display value and the analogue input value.

Setting the start/offset value of the measuring range, offs:

Default: 0

Enter the start/offset value from the smallest to the highest digit [▲] [▼] and confirm each digit with [P]. After the last digit the display switches back to the menu level. If Sens.F was selected as the input option, you can only select between noca and cal. With noca, only the previously set display value is taken over, and with cal, the device takes over both the display value and the analogue input value.

Setting the decimal point, dot:

Default: 0

The decimal point on the display can be moved with [▲] [▼] and confirmed with [P]. The display then switches back to the menu level again.

Setting up the display time, SEC:

Default: 1.0

then

The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up to 1 sec and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing the [P] button.

The display then switches back to the menu level again.

Rescaling the measuring input values, EndA:

Default: 10000

With this function, you can rescale the input value of e.g. 8.000 Hz (works setting) without applying a measuring signal. If sensor calibration has been selected, these parameters are not available.

9

5. Setting up the device

Menu level Parameterisation level

Rescaling the measuring input values, OFFA:

Default: 0

With this function, you can rescale the input value of e.g. 100 Hz (works setting) without applying a measuring signal. If sensor calibration has been selected, these parameters are not available.

Setting of the pulse delay, dELAY:

Default: 0

With the pulse delay of 0–250 s (max), frequencies can be collected, which are even smaller than by the predetermined measuring time of the device. If e.g. a delay of 250 seconds is set, this means that the device waits up to 250 seconds for an edge, before it assumes a 0 Hz frequency. Thus frequencies up to 0.004 Hz can be collected.

Adjustment of the optimum digital frequency filter, fi.frq:

Default: NO

If the optional filter is not activated by the adjustment „No“, frequencies are ignored by the adjusted frequency filter. Act on the assumption that the pulse-duty factor is 1:1. Accordingly the minimal pulse duration is derived from the half of the time of oscillation. Use a filter of 10 Hz or 20 Hz for contact bounce suppression.

Selection of analog output, Out.rA:

Default: 4-20

Three output signals are available: 0-10 VDC, 0-20 mA and 4-20 mA, with this function, the demanded signal is selected.

Setting up the final value of the analog output, Out.En:

Default: 10000

The final value is adjusted from the smallest digit to the highest digit with [▲] [▼] and digit by digit confirmed with [P]. A minus sign can only be parameterised on the highest digit. After the last digit, the device changes back into menu level.

10

5. Setting up the device

Menu level Parameterisation level

Setting up the initial value of the analog output, Out.OF:

Default: 00000

The final value is adjusted from the smallest digit to the highest digit with [▲] [▼] and digit by digit confirmed with [P]. A minus sign can only be parameterised on the highest digit. After the last digit, the device changes back into menu level.

Threshold values / limit values, LI-1:

Default: 2000

For both limit values, two different values can be parameterized. With this, the parameters for each limit value are called up one after another.

Hysteresis for limit values, HY-1:

Default: 00000

For all limit values exists a hysteresis function, that reacts according to the settings (threshold exceedance / threshold undercut).

Function if display falls below / exceeds limit value, FU-1:

Default: high

The limit value undercut can be selected with Louu (LOW = lower limit value) and limit value exceedance can be selected with high (HIGH = upper limit value). If e.g. limit value 1 is on a switching threshold of 100 and occupied with function „high“, the alarm will be activated by reaching the threshold. If the limit value is allocated to „Low“, an alarm will be activated by undercut of the threshold. See page 29.

Threshold values / limits, LI-2:

Default: 3000

This value defines the threshold, that activates/deactivates an alarm.

Hysteresis for limit values, HY-2:

Default: 00000

The delayed reaction of the alarm is the difference to the threshold value, which is defined by the hysteresis.

11

5. Setting up the device

Menu level Parameterisation level

Function for threshold value undercut / exceedance, Fu-2:

Default: high

A limit value undercut is selected with Louu (for LOW = lower limit value), a limit value exceedance with High (for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level of 100 and allocated with function High, an alarm is activated by reaching the threshold level. If the threshold value was allocated to Low, an alarm will be activated by undercutting the threshold value, as long as the hysteresis is zero.

User code (4-digit number-combination, free available), U.CodE:

Default: 0000

If this code is set (>0000), all parameters are locked, if LOC has been selected before under menu item run. By pushing [P] during operation mode for approx. 3 seconds, Code appears in the display. To get access to the unlocked reduced parameter, the user needs to enter the preset U.Code. This code has to be entered before each parameterisation, until the A.Code

(Master code) unlocks all parameters again.

Master code (4-digit number-combination free available), A.CodE:

Default: 1234

With this code, all parameters can be unlocked, if LOC has been activated before under menu item run. By pushing [P] during operation mode for approx. 3 seconds, Code appears in the display. The user can now reach all parameters by entering A.codE. Leaving the parameterisation, under menu item run, the user can unlock them permanently by choosing ULOC or

ProF. So, there is no need for anew code entering, even by pushing [P] during operation mode again.

5.3. Programming interlock „run“

Activation / deactivation of the programming lock or completion of the standard

parameterization with change into menu group level (complete function range), run:

Default: uloc

Choose between the deactivated key lock Uloc (works setting) and the activated key lock Loc, or the menu group level ProF, with the navigation keys [▲] [▼]. Confirm the selection with [P].

After this, the display confirms the settings with "- - - - -", and automatically switches to operating mode. If Loc was selected, the keyboard is locked. To get back into the menu level, press [P] for 3 seconds in operating mode. Now enter the CODE (works setting 1 2 3 4) that appears using [▲] [▼] plus [P] to unlock the keyboard. FAIL appears if the input was wrong.

To parameterise further functions ProF needs to be set. The device confirms this setting with

„- - - - - „ and changes automatically into operation mode. By pressing [P] for approx. 3 seconds in operation mode, the first menu group InP is shown in the display and thus confirms the change into the extended parameterisation. It stays activated as long as ULOC is entered in menu group RUN , thus the display is set back in standard parameterisation again.

Selection of the input signal, TYPE:

Default: frequ

If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range needs to be preset under rAnGE and is adjusted by application of the final value / initial value. If FrEqU

(Factory calibration) is preferred, the final value needs to be entered under End and the final frequency needs to be entered under EndA. Under OFFS the initial value needs to be entered and under OFFSA the initial frequency. There is no application of the measuring signal. Rotar is the rotation in r.p.m. up to 10 kHz input frequency. Posit is the position recognition per incremental encoder. Confirm the selection with [P] and the display switches back to menu level.

Adjustment of pulses per rotation, ppr:

Default: 1

This parameter ist only important if type = rotar or = Posit have been selected. Generally it shows the number of pulses per rotation.

Menu level Parameterisation level

Setting the final value of the measuring range, END:

Default: 10000

Set the final value from the smallest to the highest digit with [▲] [▼] and confirm each digit with [P]. A minus sign can only be parameterized on the leftmost digit. After the last digit, the display switches back to the menu level. If Sens was selected as input option, one can only select between noca and cal. With noca, only the previously set display value is taken over, and with cal, the device takes over both the display value and the analogue input value.

Setting the start/offset value of the measuring range, offs:

Default: 0

Enter the start/offset value from the smallest to the highest digit [▲] [▼] and confirm each digit with [P]. After the last digit the display switches back to the menu level. If Sens.F was selected as the input option, you can only select between noca and cal. With noca, only the previously set display value is taken over, and with cal, the device takes over both the display value and the analogue input value.

Setting the decimal point, dot:

Default: 0

The decimal point on the display can be moved with [▲] [▼] and confirmed with [P]. The display then switches back to the menu level again.

Default: 1.0

then

The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up to 1 sec and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing the [P] button.

The display then switches back to the menu level again.

Rescaling the measuring input values, EndA:

Default: 10000

With this function, you can rescale the input value of e.g. 8.000 Hz (works setting) without applying a measuring signal. If sensor calibration has been selected, these parameters are not available.

14

5. Setting up the device

Menu level Parameterisation level

Rescaling the measuring input values, OFFA:

Default: 0

With this function, one can rescale the input value of e.g. 100 Hz (works setting) without applying a measuring signal. If sensor calibration has been selected, these parameters are not available.

Setting up the pulse delay, dELAY:

Default: 0

With the pulse delay of 0–250 seconds (maximum), frequencies that are even smaller than by the predetermined measuring time of the device, can be collected. If e.g. a delay of 250 seconds is set, it means that the device waits up to 250 seconds for an edge, before it assumes a 0 Hz frequency. Thus frequencies up to 0.004 Hz can be collected.

Adjustment of the optimum digital frequency filter, fi.frq:

Default: NO

If the optional filter is not activated by the adjustment „No“, frequences are ignored by the adjusted frequency filter. Act on the assumption that the pulse-duty factor is 1:1. Accordingly the minimal pulse duration is derived from the half of the time of oscillation. Use a filter of 10 Hz or 20 Hz for contact bounce suppression.

Adjustment of the pulse-duty factor at activated digital filter, fi.rat:

Default: i-i

Adjustment of the desired pulse-duty factor for pulse duration and pulse interruption. Like this, a special pulse behaviour can be adjusted.

Setting up the tare/offset value, tArA:

Default: 0

The given value is added to the linerarized value. In this way, the characteristic line can be shifted by the selected amount.

5. Setting up the device

Menu level Parameterisation level

Number of additional setpoints, SPCt:

Default: 00

30 additional setpoints can be defined to the initial value and final value, so linear sensor values are not linearised. Only activated setpoint parameters are displayed.

Display values for setpoints, dIS.01 … dIS.30:

Under this parameter setpoints are defined according to their value. At the sensor calibration, like at final value/offset, one is asked at the end if a calibration shall be activated.

Analog values for setpoints, InP.01 … InP.30:

These setpoints are displayed at works setting (4-20 mA) only. Here, demanded analog values can be choosen freely. The input of steadily rising analog values needs to be done selfcontained.

Display underflow, dI.Und:

Default: -19999

With this function the device undercut (_ _ _ _ _) can be defined on a definite value.

Display overflow, dI.OUE:

Default: 99999

With this function the display overflow (

_ _ _ _ _

) can be defined on a definite value.

Input variable of process value, SIG.in:

Default: a.meas

This parameter controls the device via the analog input signals a.meas = Sens.f repectively fre9u or via the digital signals of the interface M.bus = RS232/RS485 (Modbus protocol). Confirm the selction with [P] and the device changes back into menu level.

Back to menu group level, rEt:

With [P] the selection is confirmed and the device changes into menu group level „–INP–“.

Display time, DISEC:

Default: 01.0

then

The display is set up with [▲] [▼]. Thereby on switches until 1 second in 0.1 steps and until

10.0 seconds in 1.0-steps. With [P] the selection is confirmed and the device changes into menu level.

Rounding of display values, round:

Default: 00001

This function is for instable display values, where the display value is changed in increments of

1, 5, 10 or 50. This does not affect the resolution of the optional outputs. With [P] the selection is confirmed and the device changes into menu level.

Arithmetic, ArItH:

Default: no

Reciprocal

Root extraction

Square

With this function the calculated value, not the measuring value, is shown in the display. With no, no calulation is deposited. With [P] the selection is confirmed and the device changes into menu level.

Sliding average determination, AVG:

Default: 10

Here, the number of the meterings that need to be averaged is preset. The time of averaging results of the product of measuring time SEC and the averaged metering AVG. With the selection of AVG in the menu level DISPL, the result will be shown in the display and evaluated via the alarms.

17

5. Setting up the device

Menu level Parameterisation level

Dynamic for the sliding average determination, step:

Default: no

With step the sliding average determination can be adjusted dynamically. If 6pro or 12pro is selected, a frequency value with a variance of 6% or 12% of the current display value is taken over directly for the sliding averaging. The display appears to be more dynamic at a fast frequency change, without appearing disturbed by a slightly unsteady frequency.

Zero point slowdown, ZErO:

Default: 00

At the zero point slowdown, a value range around the zero point can be preset, so the display shows a zero. If e.g. a 10 is set, the display would show a zero in the value range from -10 to

+10; below continue with -11 and beyond with +11.

Definite contstant value, const:

Default: 0

The constant value can be evaluated via the alarms or via the analog output, like the current measurand. The decimal place cannot be changed for this value and is taken over by the current measurand. Like this a setpoint generator can be realised via the analog output by this value. Furthermore it can be used for calculating the difference. At this the constant value is substracted from the current measurand and the difference is evaluated in the alerting or by the analog output. Thus regulations can be displayed quite easily.

Minimum constant value, con.mi:

Default: -i9999

The minimum constant value is adjusted from the smallest to the highest digit with the navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be adjusted on the leftmost digit. After the last digit the display changes back into menu level.

Maximum constant value, con.ma:

Default: 99999

The maximum constant value is adjusted from the smallest to the highest digit with the navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be adjusted on the leftmost digit. After the last digit the display changes back into menu level.

Brightness control, Light:

Default: 15

The brightness of the display can be adjusted in 16 levels from 00 = very dark to 15 = very bright via this parameter or alternatively via the navigation keys. During the start of the device the level that is deposited under this parameter will always be used, even though the brightness has been changed via the navigation keys in the meantime.

Display flashing, FLASH:

Default: no

A display flashing can be added as additional alarm function either to single or to a combination of off-limit condition. With no, no flashing is allocated.

Assignment (deposit) of key functions, tASt:

Default: no

For the operation mode, special functions can be deposited on the navigation keys [▲] [▼], in particular this function is made for devices in housing size 48x24mm which do not have a 4th key ([O]-key). If the min/max-memory is activated with EHtr, all measured min/max-values are safed during operation and can be recalled via the navigation keys. The values get lost by restart of the device. If the threshold value correction LI.12 or LI.34 is choosen, the values of the threshold can be changed during operation without disturbing the operating procedure. With tArA the device is tared to zero and safed permanently as offset. The device confirms the correct taring by showing ooooo in the display. Set.tA switches into the offset value and can be changed via the navigation keys [▲] [▼].

Via totAL the current value of the totaliser can be displayed for approx. 7 seconds, after this the device changes back onto the parameterised display value. If tot.rE is deposited, the totaliser can be set back by pressing the navigation keys [▲] [▼], the device acknowledges this with showing ooooo in the display. The configuration of EHt.rE deletes the min/max-memory. Under

ActuA the measurand is shown for approx. 7 seconds, after this the display returns to the parameterised display value. The brightness can be adjusted with light. This adjustment is not safed and lost at a restart of the device. If no is selected, the navigation keys are without any function in the operation mode.

For the operation mode, special functions can be deposited on the [O]-Taste. This function is activated by pressing the key. With tArA the device is set temporarily on a parameterised value.

The device acknowledges the correct taring with oo0oo in the display. Set.tA adds a defined value on to the currently displayed value. Via totAL the current value of the totaliser can be displayed for approx. 7 seconds, after this the device switches back on the parameterised display value. If tot.rE is deposited, the totaliser can be set back by pressing of the navigation keys [▲] [▼], the device acknowledges this with ooooo in the display. EHt.rE deletes the min/max-memory. If HOLD has been selected, the moment can be hold constant by pressing the

[O]-key, and is updated by releasing the key. Advice: Hold is activated only, if HOLD is selected under parameter DISPL. ActuA shows the measuring value for approx. 7 seconds, after this the device switches back on the parameterised display value. The same goes for AVG, here the sliding average values will be displayed. The constant value const can be recalled via the digital input, or changed digit per digit. At AL-1…AL-4 an output can be set and therewith e.g. a setpoint adjustment can be done. If no is selected, the [O]-key is without any function in the operation mode.

Working principle

Operating current / Quiescent current

Operating current

By operating current the alarm S1-S2 is off below the threshold and on on reaching the threshold.

Quiescent current

By quiescent current the alarm S1-S2 is on below the threshold and switched off on reaching the threshold.

30

Switching-on delay

The switching-on delay is activated via an alarm and e.g. switched 10 seconds after reaching the switching threshold, a short-term exceedance of the switching value does not cause an alarm, respectively does not cause a switching operation of the relay. The switching-off delay operates in the same way, keeps the alarm / the relay switched longer for the parameterised time.

8. Programmer examples

Example for the rotation speed adjustment:

In this application the rotation speed of an axis shall be collected via a toothed wheel with 30 sprockets, per

Namur sensor. It is then displayed with one position after decimal point and the dimension rpm.

Parameter Settings Description

Rotation – rotation speed measurment up to 10 kHz

Number of sprockets

1 position after decimal point

Advice: The input frequency may be maximum 9.999 kHz in this operating module. So, a rotation speed parameterisation via the frequency adjustment is rarely necessary.

Example for the position coverage:

A measuring system for length works via a incremental encoder with two dephased output signals (typically

A and B) and 100 pulse/rotation. The axis perimeter was calculated in a way that the measuring section can be extracted by a rotation of 6 cm = 60 mm. The display shall show the relative position in millimeter. There is a zero joint position with a limit switch that can zero the display if required.

Parameter Settings Description

Positioning – rotary encoder

Pulse number per rotation

Change of length per rotation

Display zero

Advice: The display starts always on position zero. The parameter dig.in can be found under parameter group –fct– in the extended parameterisation Prof.

Example for angle coverage:

On a manually operated bender for sheet metal the bending angle shall be displayed in degree. The device is in zero state (0°) during switching on of the display. An incremental encoder with 360 pulses/rotation is used.

Parameter Settings Description

Positioning – rotary encoder

Pulse number per rotation

Angle sum per rotation

8. Programmer examples

Examples: Adjustment according to number of sprockets at unknown rotation speed.

- nearly 100% of the rotation speeds are in the range of 0 to 30.000 r.p.m.

- the number of sprockets varies (without gearing) between 1 and 100

- in automation, the frequency supply never exceeds 10 kHz (rather 3 kHz)

Assume a rotation speed of 60 r.p.m. at 1 Hz, whereat the real frequency value will not be considered.

Our example complies with a number of sprockets of 64.

Setting up the advice

Based on the default settings of the display, the following parameters need to be changed:

Parameter Settings Description

Applying of the measuring signal is not applicable.

Complies with 9.9999 Hz.

Assumed final value.

Complies with 64 sprockets.

If the frequency needs to be displayed with a position after decimal point, then a 60 has to be selected as final value for this adjustment.

Parameter Settings Description

Applying of the measuring signal is not applicable.

Complies with 9.9999 Hz

Assumed final value

8. Programmer examples

Example: Rotation speed of a machine shaft

There are 4 sprockets on one machine shaft. Applied in an angle of 90° to each other and to the rotation speed measurement. The sprockets are collected via a proximity switch and evaluated by the frequency device, which shall display the rotation speed in U/min. 0…3600 U/min is preset as rotation speed range of the machine.

Calculation of the input frequency

60 x 1U min x 4 = 240 Hz

Setting up the device

Based on the default settings of the device, following parameters need to be changed:

Parameter Settings Description

As the input frequency is known, the device does not need to be applied to the measuring section.

The final frequency is in the range of 100.00 to 999.99 Hz.

A rotation speed of 3600 shall be displayed as final value.

The final frequency for display value 3600 is 24.00 Hz.

10. Safety advices

10. Safety advices

Please read the following safety advice and the assembly chapter 1 before installation and keep it for future reference.

Proper use

The M2-1F-device is designed for the evaluation and display of sensor signals.

Attention! Careless use or improper operation can result in personal injury and/or damage the equipment.

Control of the device

The panel meters are checked before dispatch and sent out in perfect condition. Should there be any visible damage, we recommend close examination of the packaging. Please inform the supplier immediately of any damage.

Installation

The M2-1F-device must be installed by a suitably qualified specialist (e.g. with a qualification in industrial electronics).

Notes on installation

• There must be no magnetic or electric fields in the vicinity of the device, e.g. due to transformers, mobile phones or electrostatic discharge.

• The fuse rating of the supply voltage should not exceed a value of 6A N.B. fuse.

• Do not install inductive consumers (relays, solenoid valves etc.) near the device and

suppress any interference with the aid of RC spark extinguishing combinations or free-wheeling diodes.

• Keep input, output and supply lines separate from one another and do not lay them parallel with each other. Position “go” and “return lines” next to one another. Where possible use twisted pair.

So, the best measuring results can be received.

• Screen off and twist sensor lines. Do not lay current-carrying lines in the vicinity. Connect the

screening on one side on a suitable potential equaliser (normally signal ground).

• The device is not suitable for installation in areas where there is a risk of explosion.

• Any electrical connection deviating from the connection diagram can endanger human life and/or can destroy the equipment.

• The terminal area of the devices is part of the service. Here electrostatic discharge needs to be avoided. Attention! High voltages can cause dangerous body currents.

• Galvanic isolated potentials within one complex need to be placed on an appropriate point

(normally earth or machines ground). So, a lower disturbance sensibility against impacted energy can be reached and dangerous potentials, that can occur on long lines or due to faulty wiring, can be avoided.

6.

Program numbers for the parameterisation of the input are not available

7.

The device shows „Err1“ in the 7-segment display

8.

The device does not react as expected.

• The input frequency is too high for the selected frequency range. Correct

„range“ according to this.

• Disturbing pulses lead to an increased input frequency, activate „fi.frq“ at smaller frequencies or shield the senor line.

• A mechanic switching contact chatters. Activate the frequency filter „fi.frq“ with

10 or 20 kHz.

• The display was taught faulty under „type“ = „Sens.f“. Error elimination see below.

• An offset frequency „offsa“ bigger than 0 Hz respectively a „Living Zero“ was selected, in which no frequency is aligned. Check the sensor lines or set the

„Offsa“ onto 0 Hz.

• The display underflow dl.und was selected too high. The according parameter needs to be adapted.

• The device was taught faulty under „type“ = „Sens.f“. Error elimination see below.

• Disturbances lead to short-term display switches. For smaller frequences use the frequency filter „Fi.frq“, select a higher measuring time or use the sliding averaging.

• The sprockets that needs to be collected, are not evenly spread on a shaft or are not measured accurately. Use the sliding averaging „Avg“ if necessary with the dynamic function „Step“. The displayed value „displ“ needs to be set on „AVG“.

• The sensor was not connected properly. Check the connection lines and if necessary the sensor supply. Best directly on the screw terminals of the device!

• A PNP- respectively NPN-output does not reach the required threshold. Check the voltage between terminal 2 and 3 with a Multimeter. Depending on signal form it generally shoud be between 4 V and 15 V. The thresholds can be checked more safely with an oscilloscope. If necessary include an external pullup or pull-down.

• A Namur-sensor does not react. Check the distance between the sensor and the sprocket / survey mark and if necessary measure the voltage between 1 and

3. In open condition the input voltage needs to be smaller than 2.2 V and in active condition bigger than 4.6 V.

• The selected range of the input frequency is too high. Reduce the frequency range „range“ to a smaller value.

• The activated frequency filter „Fi.frq“ suppresses the relevant pulses. Increase the filter frequency „fi.frq“ or use the adaption of the key proportion „fi.rat“. If this should not work, temporarily deactivate the frequency filter with „fi.frq“ = „no“.

• The device was taught faulty under „type“ = „Sens.f“. Change into „Type“ „Frequ“ and preset the assumed frequency range „range“ and the according initial and final values „end“, „offs“, „Enda“, and „offsa“. So you can check if a frequency signal was connected to the input.

• The device located an error in the configuration memory, excecute a reset to the default values and set up the device according to your application.

• The programming interlock is activated.

• Enter correct code.

• Contact the manufacturer if errors of this kind occur.

• If you are not sure, that the device has been parameterised before, restore the state of delivery as described in chapter 6.
