MCAC-ATSM-2014-09 Aqua tempo power series tropical air-cooled scroll chiller 50Hz
199
Use PQE connect with each other when several wired-controllers are parallel.
The wiring procedure and principles are shown in the figure:
1.1.7. Basic conditions of operating the wired controller
:
1) Applicable range of supply voltage: Input voltage is 10V AC.
2) Operating environment temperature of wired controller: -10°C~+43°C.
3) Operating RH of wired controller: RH 40%~RH90%.
1.1.8. Main functions of the wire controller as follows:
1) Touch key operation;
2) LCD displays operation parameters;
3) Multiple timer;
4) Buzzer prompt tone and alarm functions;
5) Real-time clock function.
Note:
The MODBUS gateway can be customized, the MODBUS protocol built in wired controller
KJRM-120D/BMK-E, through the X/Y/E communication port of KJRM-120D/BMK-E to realize BMS system.
1.1.9 Control and protection function of unit
The unit has the following protection functions:
1) Current cut-off protection
2) Power supply phase sequence protection
3) Protection for over-low suction pressure
4) Protection for compressor overcurrent
5) Protection for compressor overload
6) Anti-freezing protection
7) Protection for over-high discharge pressure
8) Protection for outlet and inlet water temperature
The unit also has other control functions:
1) Plug and play system
2) RS-485/TS232 Standard serial communication port
