4.1. Switching on
Once the installation is complete, you can start the device by applying the current loop. Check beforehand once again that all the electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test (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 start-up sequence, the device switches to operation/display mode.
4.2. Standard parameterization:
To be able 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 Parameterization level
Selection of the input signal, TYPE :
As input versions, resistance values of 1, 10, 100 or 1000 kΩ signals as factory calibration (without connected sensor signal) and SENS (with connected measuring signal) as sensor calibration are available. Confirm with [P]. The display then switches back to the menu level again.
Setting the final value of the measuring range, END :
The final value is adjusted from the lowest to the highest place with [▼] [▲] and confirmed place selective with [P]. A minus sign can only be parameterized on the highest place. After the last place the display switches back to the menu level. If SENS has been selected, you can then choose between NOCA and CAL. At NOCA the before adjusted value will be taken over, at CAL the value alignment via the measuring section takes place and the analog input value is taken over.
Setting the initial value of the measuring range, offs :
The initial value is adjusted from the lowest to the highest place with [▼] [▲] and confirmed place selective with [P]. After the last place the display switches back to the menu level. If SENS has been selected, you can then choose between NOCA and CAL. At
NOCA the before adjusted value will be taken over, at CAL the value alignment via the measuring section takes place and the analog input value is taken over.

4. Setting up the device
Menu level Parameterization level
Setting the decimal place / sign of physical unit, END:
The decimal place and the physical unit are set with [▼] [▲]. Confirm with [P], the display then switches back to the menu level again.
Setting the display time, SEC: 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 to 10.0 seconds. Confirm the selection by pressing the [P] button. The display then switches back to the menu level again.
Activation / deactivation of the programming lock and completion of the
standard parameterization, run:
With the aid of the [▲] [▼] keys, you can choose between the deactivated key lock
Uloc (works setting) and the activated key lock Loc . Make 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, you must press [P] for 3 seconds in operating mode. You must now enter the CODE (works setting 1 2 3 4 ) that appears using the [▲] [▼] keys plus [P] to unlock the keyboard. FAIL appears if the input is wrong.

4.3. Extended parameterization
By pressing the [▲] & [▼] buttons during standard parameterization for one second, the display switches to the extended parameterization mode. Operation is the same as in standard parameterization.
Menu level Parameterization level
Rescaling of measuring input values, EndA:
With this function the final value e.g. 1500 Ω (factory setting) can be rescaled without connecting of a measuring signals. At selected sensor calibration these parameters are not available.
Rescaling of measuring input values, OFFA:
With this function the initial value e.g. 500 Ω (factory setting) can be rescaled without connecting of a measuring signals. At selected sensor calibration these parameters are not available..
Setting of Tara value / Offset value, tArA:
The preset value is add to the linearized value. This way, the characteristic line can be adjusted according to the selected value.
. Zero point tranquilization, ZErO:
With zero point tranquilization, a value range around zero can be preselected at which the display shows zero. If, for example, a 10 is set, the display would show a zero in the range from -10 to +10 and continue below it with -11 and above it with +11.

Menu level Parameterization level
4.3.1. MIN/MAX value inquiry - Assignment of key functions, Tast:
Here, you can enter for the operating mode either a MIN/MAX value inquiry or a threshold value correction on the arrow keys.
If the MIN/MAX memory is activated with EHER , the measured MIN/MAX values will be saved during operation and can be called up via the arrow keys [▲] [▼]. The values
LI.1
is selected, the are lost if the device is restarted. If the threshold value correction limit values can be changed during operation without hindering the operating procedure. If No is parameterized, the arrow keys [▼] [▲] have no function in operating mode.
4.3.2. Flashing of display, FLAS:
Here, flashing of the display can be added as an extra alarm function, either to the first limit value (select: LI-1 ), the second limit value (select: LI-2 ) or to both limit values
(select: LI-12 ). With No (works setting), no flashing is assigned at all.
4.3.3. Limit values / Limits, LI-1:
For both limit values, two different values can be parameterized. With this, the parameters for each limit value are called up one after the other.
Hysteresis for limit values, HY-1:
For both limit values, a hysteresis function exists that reacts according to the functional principle (operating current / quiescent current).
Function if display falls below / exceeds limit value, FU-1:
To indicate if the value falls below the lower limit value, Louu can be selected (LOW = lower limit value) and if it goes above the upper limit value, high can be selected
(HIGH = upper limit value). LOW corresponds to the quiescent current principle and
HIGH to the operating current principle.

7. Safety advices
7. Safety advice
Please read the following safety advice and the assembly chapter 1 before installation and keep it for future reference.
Proper use
The M1-device is designed for the evaluation and display of sensor signals.
Danger!
Careless use or improper operation can result in personal injury and/or 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 M1-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, 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 insulated potentials within one complex need to be placed on a 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.
