For this purpose, the actuator must be mechanically connected to a Siemens valve (see «Compatibility») and must have a supply voltage of AC 24 V. The calibration procedure can be repeated as often as necessary. %HIRUHVWDUWLQJFDOLEUDWLRQHQVXUHWKDWWKHPDQXDODGMXVWHULVVHWWR $XWRPDWLFª LQRUGHUWRUHJLVWHUWKHDFWXDODOXHV There is a slot on the printed circuit boards of the actuators. To initiate the calibration procedure, the contacts inside this slot must be short-circuited (e.g. with a screwdriver). Automatic calibration proceeds as follows: Actuator runs to the «0 stroke» position (), valve closes, green LED flashes. Actuator then runs to the «100 stroke» position 6WURNH (), valve opens, green LED flashes. 0% Measured values are stored. The calibration procedure is finish, and the green LED now glows steadily (normal operation). The actuator now moves to the position defined 100% by control signal or Z (). Throughout this procedure, output U is inactive, i.e. the values only represent actual positions when the green LED stops flashing and remains on continuously W /('VWDWXVLQGLFDWLRQ LED Display Function Action *UHHQ 2Q Normal operation Automatic operation, no problems )ODVKLQJ Stroke calibration in progress Wait until calibration is complete (LED stops flashing) 5HG 2Q Faulty stroke calibration Check mounting Re-start stroke calibration (by short-circuiting calibration slot) Internal error Replace electronics )ODVKLQJ Inner valve jammed Check the valve 2II No power supply Check mains Faulty electronics Replace electronics 5/14
