An ATR620 that scrolls its model name, flashes 1.18, and then shows 14 with StoP has completed the reported startup sequence. The fault condition is the keypad failing to accept the cycle-selection commands after startup, not the displayed StoP state by itself.
Interpret the startup displays
| Display | Evidence-supported interpretation |
|---|---|
ATR620 moving on the display |
Normal startup identification |
1.18 flashing with the indicators |
Occurs during the reported normal startup sequence; its exact meaning is not established by the available evidence |
14 on the upper display |
Ambient-temperature reading |
StoP on the lower display |
Controller is stopped and waiting for cycle selection |
Start a cycle from the stopped state
- Allow the controller to finish the startup display sequence and reach the temperature/
StoPscreen. - Press START/STOP to select the cycle to run.
- Press OK to confirm the selection.
Verify that the displayed selection or operating state changes after each command. The evidence does not establish a keypad-reset combination, so do not treat an undocumented multi-key sequence as a supported recovery method.
Separate normal startup from keypad failure
If the controller reaches the temperature/StoP screen, the displayed startup text is consistent with normal initialization. Test the documented operating sequence rather than diagnosing 1.18, 14, or StoP as error codes.
If START/STOP produces no selection and OK produces no confirmation, repeat the test after one normal power cycle. A controller that consistently reaches StoP but accepts no key input has a probable controller or keypad fault; the evidence does not isolate the failed component.
Decide the next action
Record the complete display sequence and identify which keys, if any, cause a visible change. If all six keys remain unresponsive after startup and a normal power cycle, arrange inspection or repair through the manufacturer or equipment supplier. Do not claim a software reset will resolve the condition without a documented ATR620 reset procedure.
FAQ
Why does my ATR620 show 14 and StoP after power-on?
The upper value is the ambient-temperature reading, while StoP indicates that the controller is stopped and waiting for cycle selection.
How do I start an ATR620 cycle from the StoP screen?
Press START/STOP to select the required cycle, then press OK to confirm it.
What should I do when none of the ATR620 keys respond?
Confirm that the controller reaches the temperature/StoP screen, test START/STOP followed by OK, and repeat after one normal power cycle. If every key remains unresponsive, treat controller or keypad damage as probable and arrange inspection; no reset-key combination is established by the available evidence.
