1. Brief description

The panel meter M2-1F can evaluate pulses in many different ways and shows the result in the

5-digit LED-display. 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 under menu item .

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

under menu item .

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 saved. 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 saved 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

Function chart:

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 saved 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!

Menu level Parameterisation level

Selection of the input signal,

Default:

If the scaling of the device is done via (Sensor calibration), the frequency

range needs to be preset under and is adjusted by application of the final

value / initial value. If (Factory calibration) is preferred, the final value needs

to be entered under and the final frequency needs to be entered under .

Under the initial value needs to be entered and under the initial

frequency. There is no application of the measuring signal. is the rotation in

r.p.m. up to 10 kHz input frequency. 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, :

Default:

This parameter is only important if = or = has been selected.

Generally it shows the number of pulses per rotation.

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

Default:

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, :

Default:

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,

Default:

With this function, 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.

5. Setting up the device

Menu level Parameterisation level

Setting of the pulse delay,

Default:

With the pulse delay of 0–250 seconds (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,

Default:

If the optional filter is not activated by the adjustment , 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,

Default:

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,

Default:

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.

5. Setting up the device

Menu level Parameterisation level

Setting up the initial value of the analog output,

Default:

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,

Default:

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,

Default:

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,

Default:

The limit value undercut can be selected with (LOW = lower limit value) and

limit value exceedance can be selected with (HIGH = upper limit value). If e.g.

limit value 1 is on a switching threshold of 100 and occupied with function , the

alarm will be activated by reaching the threshold. If the limit value is allocated to

, an alarm will be activated by undercut of the threshold..

Threshold values / limits,

Default:

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

5. Setting up the device

Menu level Parameterisation level

Hysteresis for limit values,

Default:

The delayed reaction of the alarm is the difference to the threshold value, which is

defined by the hysteresis.

Function for threshold value undercut / exceedance,

Default:

A limit value undercut is selected with (for LOW = lower limit value), a limit

value exceedance with (for HIGH = higher limit value). If e.g. limit value 1 is on

a threshold level of 100 and allocated with function , an alarm is activated by

reaching the threshold level. If the threshold value was allocated to 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), :

Default:

If this code is set (>0000), all parameters are locked, if has been selected

before under menu item . By pushing [P] during operation mode for approx. 3

seconds, appears in the display. To get access to the unlocked reduced

parameter, the user needs to enter the preset . This code has to be entered

before each parameterisation, until the (Master code) unlocks all

parameters again.

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

Default:

With this code, all parameters can be unlocked, if has been activated before

under menu item . By pushing [P] during operation mode for approx. 3

seconds, appears in the display. The user can now reach all parameters by

entering . Leaving the parameterisation, under menu item , the user can
