Detail information
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 (18A), it will be shut down and re-started after 3 min.
3
T4: outdoor ambient temp. sensor (fault code E7)
T3B: pipe temp. sensor of the condenser B (fault code E6 and protection code P7)
T3A: pipe temp. 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.
Outdoor fans set high wind, low wind two respectively, and control the unit through T4.
2) T3B and T3A: when the electric control of the modular unit detects the temp. of the outdoor pipe T3A or T3B of the
system exceeds the protective temp. 65
℃
, the corresponding system will be shut down. And it will be re-started up,
after the temp. drops below the recovery temp. 60
℃
. Another system will be not affected.
3) T4, T3B and T3A: when the temp. sensor is detected to suffer open circuit or short circuit, fault alarm will occur.
●
When the main unit suffer fault of temp. sensor: the main unit and subordinate units will be shut down.
●
When the subordinate unit suffer fault of temp. sensor: the unit will be shut down, but other subordinate units will not
be affected.
4
System A digital compressor exhaust temp. sensor(fault code E8, protection codeP8),Only the digital modular is
valid, and the constant speed modular are invalid.
