Connectors
On-board connectors are located in order to group all signals depending on their address (car, shaft,
machine room). Connectors name and pin numbering are printed on the board as follows:
• AUX Connection to board with auxiliary
relay SEC-3AUX
• SCB connection to SEC-3S safety circuit
board
• USB USB plug
• PRG software download
• RS232 remote connection
