1 Detection of current of the compressor B (protection code P5)
2
Detection of current of the compressor A (protection code P4)
Current is not detected within the initial 5 seconds after the compressor is started up. When the current of the
compressor is detected to exceed protective value set (33A for constant speed compressor), it will be shut down and
re-started after 3 min.
3
T4: outdoor ambient temperature sensor (fault code E7)
T3B: pipe temperature sensor of the condenser B (fault code E6 and protection code P7)
T3A: pipe temperature sensor of the condenser A (fault code E5 and protection code P6)
1) T4: if there is one system that requires starting outdoor fans, the fans are started through electric control of the unit.
Start outdoor fan A only, start A and B gears, and control the unit through T4.
2) T3B and T3A: when the electric control of the modular unit detects the temperature of the outdoor pipe T3A or T3B
of the system exceeds the protective temperature 65
。
C, the corresponding system will be shut down. And it will be
re-started up, after the temperature drops below the recovery temperature 60
。
C. Another system will be not affected.
3) T4, T3B and T3A: when the temperature sensor is detected to suffer open circuit or short circuit, fault alarm will
occur.
●
When the main unit suffer fault of temperature sensor: The main unit and subordinate units will be shut down.
●
When the subordinate unit suffer fault of temperature sensor: The unit will be shut down, but other subordinate units
will not be affected.
