MULTISTACK USER FRIENDLY CONTROLLER

LATEST SATE OF THE ART, TOUCH SCREEN, USER FRIENDLY,

MICRO PROCESS CONTROLLER. The “MV6”

52

MULTISTACK USER FRIENDLY CONTROLLER

COMPUTER CONTROL

A computer control with 5.7” touch panel and monitoring system runs the Multistack chiller bank and schedules eachcompressor off or on and capacity control of stages, depending on the changing cooling load. The system continuouslyand comprehensively monitors total operating conditions of all refrigeration circuits of the chiller bank. Maximum 32compressors can be monitored.

TEMPERATURE CONTROL

Multistack chiller is controlled either by entering water temperature or leaving water temperature. For variable water flow(VWF) models, controller will use leaving chilled water temperature to operate.

SYSTEM DATA AND VARIABLES DISPLAY

A comprehensive range of Chiller system / slave data and variable settings can be selected from the Multistackcomputerised monitoring system for display on the menu.

System Information: Water entering / leaving Temperature.Ambient temperatureLoading / demand loading CapacityLoad / unload time delay% of faults before remote alarm.Lead compressorCompressor run status.

MV6 CONTROLLER

COMPRESSOR SEQUENCE

MV6 accumulate running hours of each compressor and hence establish working sequence. A standby compressor withleast working hours will be activated once call when loading. Same as a compressor with most working hours will bestopped once unloading.

LOAD PROFILE

Cooling capacity of Multistack chiller is divided into 10 sections from 0% to 100%. Controller accumulates the workingtime of the chiller in each section and each compressor automatically.

FAULT REVIEW

It displays the last 60-recorded faults identified with time and date, system temperatures, individual refrigeration circuittemperatures and type of abnormal conditions.

PASSWORD

For service and maintenance, only personnel with appropriate password can access and modify the controller.

INDIVIDUAL REFRIGERATION SYSTEM MONITORING

Conditions such as high pressure, low pressure, refrigerant temperature, leaving chilled water temperature of individualrefrigeration circuits and system conditions are monitored.

SAFETY PROTECTION FEATURES

High pressure cut out.Low pressure cut out.Compressor motor protection.Low leaving chilled water temperature cut out for each slave and system.Low suction pressure.High discharge temperature.Phase failure.Phase sequence.High oil differential pressure cut out.

REMOTE CONTROL & MONITORING (RCM)- OPTIONAL

MV6 is fitted with RS485 serial port, which enables remote control monitoring (RCM) :

1. Connect to PC Under software optional supplied by Multistack, and compatible with Window version, remote controlis built to monitor chiller. Maximum communication cable length is 1200m.

2. MV6 is opened to ASCII agreement and communicated with BAS.

3. With Ethernet-card and a unique IP address, customer can built up its data transmission system via internet… ofwhich is optionally supplied by Multistack.
