The current device amplifier settings can be saved power fail safe in eightparameter sets and later queried.When switching from the programming operating mode to measuring mode,you will be asked whether or not the change is to be saved. This is describedin Chapter 4.4.3 .

You can also use remotes (PARACODE1 ... 2, see Chapter 4.5.8 ) toActivate/Load parameter sets.

RECALL: Parameter set 1 (parameter set 1 ... 8) and the factory setting(FACT. SETUP) are loaded

SAVE: Save as parameter set 1 ... 8

TRANSDUCER:Depending on the type of transducer, you can choose between the followingbridge types:

Selectable bridge types Full bridge 1) Half bridge 1) LVDT

EXCITATION:The excitation voltage for the transducer is selected.

Selectable excitation voltages 1 V 2.5 V

INPUT:Depending on which excitation voltage is chosen, the input range(approximate measuring range) can be selected for the transducer type.

AUTOCAL:Depending on the application and on the stability requirement, you can startan autocalibration cycle. This lets you correct zero point and full scale valuedrift and the longterm constancy of the measuring amplifier.Possible settings:

ON Autocalibration switched on

OFF Autocalibration switched off

ONCE Autocalibration is run once, as soon as you confirm it with. Autocalibration stays on/off, depending on the state

previously selected.

CAUTIONIf you need the analogue output signal for continuous monitoring, youmust switch autocalibration off. Reason: during the autocalibration cycle, no measured values arerecorded. This produces a monitoring gap (interval approx. 5 min.,duration approx. 1 s), which is undesirable if not dangerous duringproduction processes.

5 Example

The following example uses a measurement task to show you the functionalityof the device and the required settings.

Problem definition:The forming process in a press is to be monitored in order to obtain uniformproduct quality. The maximum force exerted by the press is to be recorded ineach cycle. To guarantee the production process, this maximum force mustfall between the lower (F1) and upper (F2) force limit.

Solution:The force characteristic measured with an S.G. force transducer (e.g.C9B/10 kN; 1 mV/V) is amplified and evaluated by the MVD2555. The peakvalue store (maximum) is used to record the maximum force and it isevaluated with two limit switches with regard to the lower and upper limits. Anadditional limit switch is provided for overload protection (emergency shutdown) of the machine.A PLC takes over the control of the process. As well as the control commandsfor the press, it gives the MVD2555 a start signal to begin the pressing cycleand once the process has finished, logically links the limit switch outputs tothe Good/Bad evaluation.The start signal from the PLC clears the contents of the peak value storethrough the MVD2555 control input. To prevent unintentional modifications,during measurement, only the Display signal selection button is enabled forthe machine operator on site.The parameter setups are protected against unauthorized modification by apassword.Device control through the remotes (remote control) must be activated.

Limit2 Checks whether the upper force limit has been reached.The input signal is the output of the peak value store(maximum value). If limit LV2 is exceeded, a Low signal isgenerated. A positive switch direction must be set withpositive output logic.

LV3 Checks whether the maximum load limit of the machine isexceeded (emergency shutdown function). The input signalis the gross measured value. If limit LV3 is exceeded, aHigh signal is generated. A positive switch direction mustbe set with positive output logic.

PVS1 Records the maximum peak value of the forcecharacteristic. Must be enabled, the envelope function mustbe deactivated. The input signal is the gross measuredvalue. PVS1 is cleared with remote 1 by switching toinstantaneous value.
