OJ GreenZone™ Module MP-Bus
English
Connector "P" – "Modbus out" exit port (see figs 3 and 13)
OJ GreenZone™ Module MP-Bus is equipped with a "Modbus in" (see figs 3 and 5) and
a "Modbus out" (see figs 3 and 13) RJ12 connector for integration in the zone-control
system with a standard Modbus RJ12 cable (see figs 4, 5 and 13). The terminal layout
of the RJ12 Modbus connector is shown in fig. 6. The Modbus cable must be as shown
in fig. 7. Modbus communication is OK when the green LED flashes regularly.
Addressing OJ GreenZone™ Module MP-Bus
The OJ GreenZone™ Module MP-Bus is addressed automatically by the OJ Green-
Zone™ Master to which it is connected.
The address is shown on the display of the OJ GreenZone™ Module MP-Bus (see table
3 in these instructions). Further information about addressing is found in the OJ Green-
Zone™ Master manual and in OJ Green Zone installer instructions.
Safeguarding data in OJ GreenZone™ Module MP-Bus
In the event of communication faults and/or power failure to the OJ GreenZone™
Module MP-Bus, all data will be saved. When communication and/or the power sup-
ply has been re-established, the OJ GreenZone™ Module MP-Bus will automatically
resume normal operation.
