M1 234
½-½-½M,LED 2 and LED4flash
Factorycalibrations are carried outwith sufficient accuracy and remain un-
changed during life time.However,analignment may become necessary
in some cases after servicing hardware components.
9.1 Reset Configuration to “ex factory” settings
-1--- LED 1lightsup
It is possibleto restore the configuration existingattimeof delivery via this
function.This may become necessaryifitis unclear what had been chan-
ged per menu or in the eventthatapositioner wastakenfrom one actuator
and mountedto another actuator.
Following this functionthe device is turned to condition OUTOF SERVICE.
This has to be followed by Autostartfor the purpose of adapting the calib-
ration to the actuator andtostart IN SERVICE.
The parametersofthe factory setting are listed in table Menu Structure.
Thecalibration of theinput currentor position sensor makes sense, if after
exchangeofthe electronic, the valve positionisinaccurately displayed.
Calibration of input current (OnlywithSRD with analog setpoint; does
not applytofieldbus instruments.)
Serves to equalise possibleinaccuracies in thecompletecurrent loop.
9.2 Calibrationofinput current to 4mA
--1--LED 2 lightsup
The present input current value is taken over as “4 mA”when pressing ( )
key.
9.2 Calibrationofinput current to 20 mA
-11- -LED 1and LED2lightsup
The present input current value is taken over as “20 mA”when pressing ( )
key.
Calibrationof position sensor (angle calibration)
The angle pertaining to the vertical tap position (arrow mark) is factory cali-
bratedfor thepositiontap.Ifthe position sensororthe electronics boardis
exchangedthe mechanical andelectrictolerances have to be aligned
through recalibration.
9.4 Calibrationofposition sensor value to –45°
---1- LED 3lightsup
The present position value is taken overas angle –45°when pressing ( )
key.
9.5 Calibrationofposition sensor value to +45°
-1-1-LED 1and LED3lightsup
The present position value is taken overas angle +45° when pressing ( )
key.
