5.2.2.3 Debugging operation mode
Gree Photovoltaic Direct-driven Inverter VRF System
has two debugging modes: one is
direct operation on main board of outdoor units while the other is PC operation via special
software. In PC software debugging, indoor/outdoor parameters can be displayed and historical
data can be recorded and inquired. (Operation details can be found in relevant instruction
manuals)
(1)Debugging through operation on main board of outdoor units
In this debugging mode, following debugging functions are included on the main board:
Step 1:
front panel of the outdoor units must be fully closed. Open the debugging window
of each basic module;
Step 2:
disconnect power for outdoor units. According to design requirements of external
static pressure, set up corresponding static pressure mode for the units. Setting methods can
be seen in Outdoor Fan Static Pressure Setup SA6_ESP_S;
Step 3:
disconnect power for outdoor units and set one module as a master unit. Setting
methods can be seen in Master Unit Setup SA8_MASTER_S;
Step 4:
Connect power for all indoor units. Make sure all IDUs are power on. Then all
outdoor modules will display “Debugging not enabled”;
Step 5:
Find the module with “01” module address to be the master module. Hold SW7
