When embedding the Nano Safety Controller Pro in your equipment, keep in mind the following clearances:

Primary side of board clearance 4 mm.
Secondary side of board clearance > 5 mm
Secondary side of board standoff = 9 mm
Secondary side of board connector TE 5177986-3 (80-pin connector) — engages with TE 5-5179180-3 connector

See NSC PRO 80-Pin I/O Connector Pinout for a description of the connector pins.

Note:

The two connectors on the right of the secondary side of the board, J36 and J37, are for FORT internal use only.

Data Interfaces (NSC Pro)

The NSC Pro’s integration interface is CAN (Controller Area Network) or UART (Universal Asynchronous Receiver-Transmitter).

Important:

The NSC Pro does not have a built-in CAN transceiver so if you use CAN, you must purchase and install your own.

Note that the NSC Pro supports the J1939 protocol only. J1939 Implementation describes CAN communication specifications (data rates and protocol). Use the Endpoint Controller’s dual safety outputs to prevent any motion of the equipment under control (EUC) when the Endpoint Controller receives an emergency stop from either the connected remote device or its wired emergency stop input. The emergency stop inputs are relative to PVin. Maintain a single ground reference for all power and reverence voltages.

The following table provides specifications for the CAN interface:

Specification	Minimum	Typical	Maximum
CAN TX High Level Output Voltage	3 V	3.3 V
CAN TX Low Level Output Voltage	0 V	0.1 V

LED Diodes

The Nano Safety Controller Pro has four LED lights on the primary side of the board (as shown in the following figure) that are useful for testing (D36 and D37 for the application processor and D17 and D18 for the safety processor):

../images/nscp_led.jpg — Figure 6. Fig. 40 NSC Pro LEDs

Application Processor Status During Secure Boot

When power is applied to the NSC Pro, the secure bootloader begins the boot process. The following table lists LED indicators controlled by the application processor bootloader during secure boot.

Table 10. Table 77 Application Processor Status during Secure boot
LED	Source	Indicates
D36 Red	Secure bootloader	On (red) when bootloader is executing.
D36 Green	Secure bootloader	On (green) when bootloader is launching application firmware.
D37 Red	Secure bootloader	On (red) during firmware update, and a flash sector erase is in progress.
D37 Green	Secure bootloader	On (green) during firmware update, and a flash sector write is in progress.

Application Processor Status During Normal Operation

When the application processor firmware is starting, all LED indicators are cleared. The following table lists LED indicators controlled by the application processor firmware during normal operation.

Table 11. Table 78 Application Processor Status Normal Operation
LED	Source	Indicates
D36 Red	Application firmware	Undefined (disable) in this context.
D36 Green	Application firmware	Undefined (disable) in this context.
D37 Red	Application firmware	Undefined (disable) in this context.
D37 Green	Application firmware	Blinks (green) at 2Hz when application processor is in normal operation.

Safety Processor Status During Normal Operation

The following table lists LED indicators controlled by the safety processor firmware during normal operation.

Table 12. Table 79 Safety Processor Status Normal Operation
LED	Source	Indicates
D17 Red	Application firmware	On (red) when safety outputs are asserted.
D17 Green	Application firmware	Blinks (green) at 1Hz when Safety Processor 0 is in run state.
D18 Red	Application firmware	On (red) when safety outputs are asserted.
D18 Green	Application firmware	Blinks (green) at 1Hz when Safety Processor 1 is in run state.

Note:

Don’t confuse these LEDs on the board with the three GPO connectors (Pins 5, 7, and 9 on the 80 pin connector) that you can wire to external LEDs to provide status information (see NSC PRO 80-Pin I/O Connector Pinout). The LEDs are on the board and hence hidden after you embed the NSC Pro in your equipment, which makes them useful only for testing.

ISM Radio LEDs

The ISM radio board has three LEDs that are useful for testing.

Table 13. Table 80 ISM Radio Board LEDs
LED	Schematic	Indicates
D3 Green	LED_TX	Indicates TX (transmission) activity.
D3 Red	LED_TX	Indicates TX Error.
D4 Green	LED_RX	Indicates RX (reception) activity.
D4 Red	LED_RX	Indicates RX error (remains lit until error is cleared).
D5 Green	LED_STAT	Status heartbeat
D5 Red	LED_STAT	Status Error (remains lit until error is cleared).

¹ You can use a USB connector (with pins 2 and 4) to configure and perform firmware updates to the NSC Pro. The NSC Pro, however, will not detect a USB connection unless USB Power is provided to the NSC Pro, that is, you’ve connected a device (through pin 6) that provides USB power. Note that the NSC Pro will still be powered by the supply with the higher voltage if the Main Power supply is also connected.

⁴ You can use Pins 50 & 54 or 58 & 62 to connect to the Linux computer running the FORT SDK (UART to IP bridge) or to connect to a USB port on the EUC.
