The slave annunciator will flash if it does not detect a master on the network.
Check the cable and the master configuration.
A master or slave will be disabled from current sharing (set to "No share") if:
• there is more than one master connected to the CANbus, (Error +1911)
• there are more than 4 slaves, (Error +1922), or
• the model does not match that of the master, (Error +1922).
In each of these cases, the current share mode will be set to "No share".
If a unit becomes disconnected due to a failure in communications, the master will
queue error +1912, "Current Share Slave Lost" and the slave will
queue error +1921, "Current Share Master Lost." The slave's
output will be disabled, and the slave annunciator will flash.
