Rev.01 Issue 09/05 6 Functions and equipment responses Learn and test run Pushing the Door Parameter button (S5000) causes automatic parameter sensing to start: 1. Recognition of the motor type 2. Recognition of the door motion direction and the “CLOSE” position 3.
Rev.01 Issue 09/05 NOTE If the door parameter button (S5000) is pressed while applying the mains voltage, the current parameters are overwritten at the end of the training run by the factory settings. If the door parameter button is pressed during normal operation, then only a door width and a mass determination is performed.
Rev.01 Issue 09/05 Closing force The closing force can be adjusted between 70 and 230N. When 150N is exceeded a warning appears on the LCD display of the terminal module (option). The values mentioned refer to a door that opens to one side; a load cell will only indicate the half value with central opening doors.
Rev.01 Issue 09/05 6.13 Emergency power supply (option) In case of a failure of the mains voltage a battery or a rechargeable battery (e.g. lead gel rechargeable battery) can be attached to the external emergency power module (option) and thus makes possible emergency operation. The door can be opened and closed in this condition;...

Rev.01 Issue 09/05 7 Mechanical assembly and set-up CAUTION The safe operation of the lift door drive requires that it is correctly installed and put into operation by qualified personnel under consideration of the warning references in these operating instructions. Before working on the door drive you must ensure that voltage has been removed from the controller.
Rev.01 Issue 09/05 8 Electrical set-up and initial start-up WARNING With the operation of electrical equipment inevitably some parts of the equipment contain dangerous voltage. Neglecting the operating instructions can therefore lead to severe bodily injuries or property damage. Therefore the warnings must be absolutely followed. During the start-up of the controller (in particular during automatic parameter determination) the door movements cannot always be externally influenced.

Rev.01 Issue 09/05 Speed limit curve The speed limit curve is the characteristic used for the determination of the maximum permissible door speed V as a function of the total door leaf mass. In accordance with EN 81 the maximum kinetic energy of the door moving in the closing direction may not exceed 10 joules.

Connection with internal 24V Supply A door close command should be present when the lift is running or parked at rest with doors closed (i.e. through auxiliary contacts on a main contactor in parallel to door close contacts) This will hold the doors closed or open at a reduced torque. Please Note: With doors open, there must be a door open command present.

Rev.01 Issue 09/05 14.11 Appendix 11: Diagnosis and parameter setting For the diagnosis and setting of the parameters either the terminal module or the user terminal can be used. This Tool is optionally available (see Appendix 1). The terminal module (option) is under the housing cover. The user terminal and the USB adapter of the FrontEndPC can be attached with the appropriate cable to X8 of the controller.

Rev.01 Issue 09/05 14.12 FrontEndPC The FrontEndPC control program can be installed on a PC with USB interface. In addition to the program, drivers for the USB adapter (CP2101) must be installed (see readme.txt on the installation disk). The USB adapter is attached between the USB connection of the PC and the X8 plug connector of the AT18 controller.
Rev.01 Issue 09/05 14.12.2 Driving parameter editor Figure 14 With the run time curve editor all adjustable parameters can be loaded, comfortably adjusted and saved. The loading as well as the saving of parameters can be done in the AT18 controller. A text file can also be saved on the PC.
Rev.01 Issue 09/05 WARNING After changing the profile it is necessary to start a new learn run (start with S5000 ). Otherwise the closing speed and nudging speed can’t be limited by the door mass and the kinetic energy could be exceeded the permitted value. 14.12.3 Oscilloscope function Figure 15...
Rev.01 Issue 09/05 14.13 Minimal Editor The minimum editor is an aid for changing an AT18 controller parameter if the terminal module, user terminal or FrontEndPC is not available. Thereby the parameter button (S5000) and the two service buttons (S5001, S5002) receive a second function.
