the S-ERR LED flashes.
● The PWR LED lights up as soon as the internal supply voltage of the device is present.
● After successful initialization of the I/O bus communication to the S500 module, the I/O bus
LED lights up.
● After successful initialization of the CS31 bus communication, the CS31 bus LED lights up.
The S-ERR LED goes out.
● During operation, the yellow LEDs indicate the signal statuses of the channels.
