MCAC-ATSM-2014-09 Aqua tempo power series tropical air-cooled scroll chiller 50Hz
95
2.3 MGBT-D60W/RN1
No. Detail information
1
Detection of current of the compressor A1 (protection code P4)
2
Detection of current of the compressor B1 (protection code P5)
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 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. 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 temp. of the outdoor pipe T3A or T3B of the system
exceeds the protective temp. 65
。
C, the corresponding system will be shut down. And it will be re-started up, after the temp.
drops below the recovery temp. 60
。
C. 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
Detection of current of the compressor A2 (protection code P4)
5
Unit outlet water temp. sensor (fault code E4)
Under refrigeration mode and heating mode, conduct adjustment according to the magnitude of unit outlet water temp..
