Example 3: OPTBJ board with SS1 and safety reset or EN 60204-1 stop category 1.
The figure above presents a connection example of OPTBJ board for SS1 safety function with ex-
ternal safety relay module and with safety reset.
The external safety relay module is connected to the switch S1. The used power supply to switch S1
is 230 VAC as an example. The safety relay module is connected to OPTBJ board with 4 wires as
shown in Figure above.
When the switch S1 is activated (contacts open), the drive will go to STO state and motor (if running)
will stop by coasting. The drive will indicate: "30 SafeTorqueOff".
To start the motor operation again, following sequence is performed.
• Release the switch S1 (contacts closed). The hardware is now enabled but the drive continues to dis-
play the fault "30 SafeTorqueOff".
• Acknowledge the releasing of switch by edge sensitive reset function. The drive returns to the ready
state.
• Giving a valid start command will start running the motor
More information on the safety relay module may be found in the safety relay documentation.
NOTE! The Vacon 100 default application software uses edge-sensitive start as default start com-
mand, for preventing unexpected startup from STO state.
NOTE! For EN 60204-1 emergency stop according to stop category1, use emergency stop button.
