Typical Master/Slave Jumper Connections for Modules in the Same Chassis
The diagram below shows the ALARM OUT and ALARM IN terminal strips and jumper connections for a typical
master/slave connection between two modules in the same chassis. The master module is assumed to be in slot 4 and the
slave module is in slot 6. If a critical fault occurs in the master module, its relay signal travels from the slot 4 ALARM OUT
terminal to the slave module slot 6 ALARM IN terminal. This turns on the slave module in slot 6. The slave module
continues in operation until the master module is fixed. At that time, the master module automatically takes over and the
slave module switch relay turns off.
