TEST 3: ACTION: EXPECTED BEHAVIOR: TEST 4: ACTION: EXPECTED BEHAVIOR: OPTIMIZE MOVEMENTS Operate the door for two (2) complete open and close movements. Door should open and close normally. The microprocessor measures the torque and sets the internal speed and torque references. These references are used as safety thresholds for detecting obstructions.
® ATD 50 Actuator Operating Instructions 7 Error Diagnosis There are 10 error conditions that can be detected by installing LED’s to specific “B TERMINAL STRIP” outputs inside the ATD 50 Actuator®. The errors are indicated according to the following code: Software Error Number 2 3 9 10 11 12 13 16 29 30 Calibration run is taking place. Wait until door is closed for error to clear Main power failure. Microprocessor error or drive type not specified. Contact Factory. Emergency stop activated.
® ATD 50 Actuator Operating Instructions 8 Hardware Error Displays The microprocessor controller has a red and green LED light in the lower right corner. The LED lights indicate the general status of the microprocessor. GREEN LED The microprocessor controller is operating correctly.
® 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.
® 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: Input terminal: Type of signal: Active level This command is used when a completely opened door is not required. (Operator may wish to access inside of machine briefly). C4 Momentary or maintained contact C4 to Ground A1. Connection is normally open. Close connection to activate.
® ATD 50 Actuator Operating Instructions SET REDUCED OPEN POSITION This command sets the reduced door open position. Reason for use: Input terminal: Type of signal: Active level 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. The distance can be set using the SERsoft programming software. F2 1 second contact of F2 to Ground F1. Connection is normally open.
® 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). Closed contact when activated (error present). DOOR POSITION IS CLOSED This output is active when the door is in the closed position ± 1/8 inch.
® 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. NOTE: The automatic reversing feature is disabled during the calibration cycles! The calibration cycle must be started by the external input signals. The calibration steps are: 1. 2. 3.
® 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. The door is locked with an internal brake ONLY when in the closed position. When closed, the door waits for the next input command.

ATD Actuator Troubleshooting Guide ® Symptom Door does not move Solutions 1) Check Power to Unit x Blown Supply Fuse supplying power to ATD x Power Cable plugged into selector switch inside x Selector switch set to correct voltage (115 or 230 VAC). If wrong voltage is selected the control or power module will be damaged! x Is the supply voltage too high or too low (+/- 10%) 2) Correct Wiring x Correct signals to correct wiring terminals x External wiring error from relay, pushbutton, etc.
Symptom Door does not move (continued) Solutions 2) Mechanically Related x Does the door move freely when connected to drive Belt? x No - Does the output sheave turn without excessive effort? (The sheave will require some effort to rotate. Sheave will not “spin”!) x No – loosen the four screws around the drive sheave up to 1 full turn. Turn output sheave by hand until sheave rotates freely. Retighten all four screws.
Symptom Door begins to close (or open) but reverses Door nearly fully closed (or open) but reverses Solutions 1) Mechanical Observations x Check door path for any obstructions such as large debris, chips, tool, “rough” spot in door track, etc.
Symptom ATD 50 does not sense an Obstruction Door “Slams or Runs Slow” against end stop Solutions 1) Sensitivity was changed from “High” to “Low” or “No”. 2) Change was made with SERsoft V1.2 to ATD 50 with EPROM T3197. Use SERsoft V1.5 to correct.
