The panel meter

M2-16

is a 5-digit device for resistance values up to 100 k Ω and a visual threshold value monitoring via the display. The configuration happens via 4 front keys or via the optional PC software PM-

TOOL. An integrated programming interlock prevents unrequested changes of the parameters and can be unlocked again by an individual code. Optional the following functions are available: a digital input for triggering of Hold (Tara) or an analog output for further processing in the equipment.

By use of the two optional galvanic isolated setpoints, free adjustable threshold values can be controlled and reported to a superior master display.

The electrical connection is carried out on the back side via plug-in terminals.

Selectable functions like e.g. the request of the min/max-value, an average determination of the measuring signals, a nominal preset respectively setpoint preset, a direct change of threshold value in operation mode and additional measuring supporting points for linearisation complete the modern device concept.

4. Description of function and operation

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 here be parameterised. 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

[O]

-key (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 it changes into operating mode, if no further key operation is done within the next 10 seconds.

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 happens via a 4-pole micromatch-plug on the back side of the device, to the PC-side the connection happens 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.

7. Alarms / Relays

This device has 4 virtual alarms that can monitor one limit value in regard of an undercut or exceedance.

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. Sensor calibration Offset / Final value

8. Sensor calibration Offset/Final value

The device is equipped with a semi-automatic sensor calibration (

Srxxx

). A switching output operates the trimming resistor, which exists in some sensors. An adjustment of offset and final value takes place, after which the sensor can be used directly. Depending on parameterisation, the calibration can be realized via the 4th key or via the digital input. It is possible to key during the calibration steps. So, reference signals can be connected manually. However the calibration will be interrupted after 30 seconds.

Press actuator for minimum 3 seconds.

10. Safety advices

10. Safety advices

Please read the following safety advice and the assembly

chapter 2

for future reference. before installation and keep it

Proper use

The

M2-16-device

is designed for the evaluation and display of sensor signals.

Danger!

Careless use or improper operation can result in personal injury and/or cause damage to 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

M2-16-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

diodes.

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

• 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, you receive best measuring results.

• 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.
