3 Turn off main power supply.
4 Detach user interface from the master unit and connect it to the
slave unit.
Turn on the main power supply switch and set individual setting.
5 Perform field setting for slave unit.
6 Turn off the main power supply.
7 If there is more than one slave unit, repeat setting for each
8 Detach user interface from the slave unit, and reattach to the
master unit.
INFORMATION
▪ You do not need to rewire the user interface from the
master unit if the optional remote controller for slave
unit is used. However, remove the wires attached to the
user interface terminal board of the master unit.
▪ After the slave unit setting, remove the user interface
wiring, and rewire the user interface from the master
unit.
▪ The unit does not operate properly when two or more
user interfaces are attached to the unit in the
simultaneous operation system mode.
Setting: Computerised control (forced OFF and ON/OFF
