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 An error can occur if the door is closed slowly with conventional switches. Door closed slowly. Solution 1 Conventional Switches The D40A does not use reed switches and provides stable detection with electronic switches.
D40A/G9SX-NS Two Types of Controller to Solve Productivity, Expandability, and Maintenance Issues The G9SX-NS and G9SX-NSA are designed specifically for use with the D40A, and with the G9SX-NSA you can also connect mechanical safety door switches. Among other features, these Controllers support logical AND connections that enable partial stops. These Controllers make the most of D40A Switches.
D40A/G9SX-NS Reduce Costs with these New-Concept Controllers Issue 1 Two Controllers are required for emergency stop switches and non-contact door switches. Application ●One hazard. ●The system must be stopped when either a door is opened or an emergency stop switch is pressed. D40B Emergency stop switch * D40A Solution 1 D40B-J1 Emergency stop switch * The D40A Simplifies the Configuration The G9SA must be added to connect the G9SA emergency stop switch.

Wiring Connect the power supply plus (24 VDC) to the A1 terminal. Connect the power supply minus (GND) to the A2 terminal. +24 V Safety input 1 Corresponds to Safety Category 2 T11, T12 T11 T12 T21 T22 To set the safety outputs in the ON state, the high state signals must be input to both safety input 1 and safety input 2.
D40A/G9SX-NS Operation Functions Logical AND Connection Connecting Expansion Units A logical AND connection means that the G9SX outputs a safety signal “a” to another G9SX, and that G9SX creates the logical AND of safety signal “a” and safety signal “b.” The safety output of the G9SX-NSA222-T03-@ with the logical AND connection shown in the following diagram is “a” AND “b.
D40A/G9SX-NS Setting Procedure 1. Cross Fault Detection (G9SX-NSA222-T03-@) Set the cross fault detection mode for safety inputs by shorting Y1 to 24 V or leaving it open. When cross fault detection is set to ON, short-circuit failures are detected between safety inputs T11-T12 and T21-22. When a cross fault is detected, the following will occur. (1) The safety outputs and logical AND outputs lock out. (2) The LED error indicator is lit. (3) The error output (auxiliary output) turns ON.

D40A/G9SX-NS Safety Precautions Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”. !CAUTION Serious injury may possibly occur due to breakdown of safety outputs. Do not connect loads beyond the rated value to the safety outputs. Serious injury may possibly occur due to loss of required safety functions. Wire the D40A and G9SX-NS properly so that supply voltages or voltages for loads do NOT touch the safety outputs accidentally.
D40A/G9SX-NS 18. Connect to the G9SX-NS@ only appropriate components or devices complying with relevant safety standards corresponding to the required level of safety category. Conformity to requirements of safety category must be determined as an entire system. It is recommended to consult an authorized certification body regarding assessment of conformity to the required safety level. 19. OMRON is not responsible for conformity with any safety standards covering the customer's entire system. 20.
D40A/G9SX-NS 11. Install the actuator and switch at an appropriate distance so that they do not create a gap that provides access to the hazard. Incorrect Correct 18. The following space must be provided around the G9SX-NS@ to enable applying the rated current to the outputs of the G9SXNS@, to ensure sufficient ventilation, and to enable wiring: 1. At least 25 mm between side surfaces of the G9SX-NS@ 2. At least 50 mm above the top surface of the G9SX-NS@ and below the bottom surface of the G9SX-NS@.
D40A/G9SX-NS 23. Logical AND connections between Units (Refer to “Functions” on page 17.) 1. To use logical AND connection inputs, enable the logical AND connection input for the G9SX-NS@ that will receive the inputs. 2. Connect the logical AND connection inputs appropriately to the logical AND connection outputs of the G9SX-@. 3. When configuring the safety system, be sure to consider that the delay of response time caused by logical AND connection does not degrade the safety functions of the system.
