[. . . ] Compact Non-Contact Door Switch/Flexible Safety Unit D40A/G9SX-NS CSM_D40A_G9SX-NS_DS_E_3_2 Electronic Detection Mechanism for Better Stability in Non-contact Door Switch Operation Be sure to read the "Safety Precautions" on page 24 and the "Precautions for All Safety Door Switches". Features Easy-to-see 2-Color Indicators Switch status is easy to see at a glance with these red/yellow LED indicators. Mount from Either Side Mount from whichever side provides the easiest wiring path to enable mounting to all types of doors. Red: Open door detected. Yellow: Closed door detected. Not lit: Power OFF or failure Swinging doors Sliding doors Small Actuator An actuator that is smaller than the switch saves space, even inside the door. Even when mounted with an L-bracket, the actuator's height will not hinder installation or operation. Compact Switch Actuator Connect Up to 30 Switches to a Single Controller Reduce costs by connecting up to 30 Switches to a single Controller. Up to 30 Switches 1 D40A/G9SX-NS Solves Conventional Switch Issues to Provide Stable Detection Issue 1 The Switch does not accurately detect the door when it is closed slowly, resulting in an error. Conventional switch Door closed slowly. An error can occur if the door is closed slowly with conventional switches. Solution 1 Conventional Switches Slow The D40A does not use reed switches and provides stable detection with electronic switches. Slow If the switching timing of reed switch contacts 1 and 2 varies too much, the Controller detects an error and turns OFF the output to maintain safety. Note: The figure is intended only as an illustration. Detects slow rotating operation. Magnet Magnet Reed switch contacts Reed switch contacts Stable Detection with the D40A's New System Error Issue 2 It is nearly impossible to tell which door is open in a multi-door application. If an error occurs. . . The system cannot be started because the Controller has turned OFF the output even though all doors appear to be closed. [. . . ] Replace with a new product. T1 flashes 1.
