Page 15: Standard Input Functions
® ATD 50 Actuator Operating Instructions 9 Standard Input Functions ® The ATD 50 Actuator can accept either momentary or maintained contacts. The factory default is momentary. If additional safety requirements are desired, you can specify MAINTAINED CONTACT for the input signals. Maintained Contact Signals can be programmed in the Basic Functions Menu in the SERsoft programming software. - Page 16 ® ATD 50 Actuator Operating Instructions REDUCED OPEN This command causes the door to open to a preset position from the closed position only. Reason for use: This command is used when a completely opened door is not required. (Operator may wish to access inside of machine briefly). Input terminal: Type of signal: Momentary or maintained contact C4 to Ground A1.
-
Page 17: Standard Output Functions
® ATD 50 Actuator Operating Instructions SET REDUCED OPEN POSITION This command sets the reduced door open position. Reason for use: The reduced open position can be manually set by using the input command at terminal F2. You must be able to manually move the door to the desired position before activating this input command. - Page 18 ® ATD 50 Actuator Operating Instructions REVERSING ERROR / GENERAL ERROR 2 This output is active when the internal and external reversing motions are initiated, usually due to an obstruction. (Error numbers 16, 29, or 30 active). Output terminal: E3 & E4 (Relay 2). Active level Contact is normally open (no error).

Page 19: Operation
® ATD 50 Actuator Operating Instructions 11 Operation 11.1 Calibration Run The first movements after a power-up or system reset are the self-calibration reference moves. The door travels to each end-stop and records the distance traveled and torque needed for movement. The door can be freely moved before a Calibration Run. -
Page 20: Door Movements
® ATD 50 Actuator Operating Instructions 11.2 Door Movements • The input signals for OPEN, CLOSE and REDUCED OPEN can be given as momentary or maintained contacts. • The door moves freely when in the open position. When open, the drive waits for the next input command signal. -
