No bare cable can be used.The ring washer which is standard provided should be removed inthat case.Attaching both cables to the power supply terminal should be doneas indicated.L1 L2 L2 N7 Configuration7.1 Overview: ConfigurationThis chapter describes what you have to do and know to configurethe system after it is installed.It contains information about:▪ Making field settings▪ Energy saving and optimum operation▪ Using the leak detection functionINFORMATIONIt is important that all information in this chapter is readsequentially by the installer and that the system isconfigured as applicable.DANGER: RISK OF ELECTROCUTION7.2 Making field settings7.2.1 About making field settingsTo continue the configuration of the VRV IV heat pump system, it isrequired to give some input to the PCB of the unit. This chapter willdescribe how manual input is possible by operating the pushbuttons/DIP switches on the PCB and reading the feedback from the7‑segment displays.Making settings is done via the master outdoor unit.Next to making field settings it is also possible to confirm the currentoperation parameters of the unit.Push buttons and DIP switchesItem DescriptionPush buttons By operating the push buttons it is possible to:▪ Perform special actions (automaticrefrigerant charge, testrun, etc).▪ Perform field settings (demand operation,low noise, etc).Item DescriptionDIP switches By operating the DIP switches it is possible to:▪ DS1 (1): COOL/HEAT selector (refer to themanual of the cool/heat selector switch).OFF=not installed=factory setting▪ DS1 (2~4): NOT USED. DO NOT CHANGETHE FACTORY SETTING.▪ DS2 (1~4): NOT USED. DO NOT CHANGETHE FACTORY SETTING.See also:▪ "7.2.2 Field setting components" on page 39▪ "7.2.3 To access the field setting components" on page 40PC configuratorFor VRV IV heat pump system it is alternatively possible to makeseveral commissioning field settings through a personal computerinterface (for this, option EKPCCAB is required). The installer canprepare the configuration (off-site) on PC and afterwards upload theconfiguration to the system.See also: "7.2.9 To connect the PC configurator to the outdoorunit" on page 45.Mode 1 and 2Mode DescriptionMode 1(monitoringsettings)Mode 1 can be used to monitor the currentsituation of the outdoor unit. Some field settingcontents can be monitored as well.Mode 2(field settings)Mode 2 is used to change the field settings ofthe system. Consulting the current field settingvalue and changing the current field settingvalue is possible.In general, normal operation can be resumedwithout special intervention after changing fieldsettings.Some field settings are used for specialoperation (e.g., 1 time operation, recovery/vacuuming setting, manual adding refrigerantsetting, etc.). In such a case, it is required toabort the special operation before normaloperation can restart. It will be indicated inbelow explanations.See also:▪ "7.2.4 To access mode 1 or 2" on page 40▪ "7.2.5 To use mode 1" on page 40▪ "7.2.6 To use mode 2" on page 41▪ "7.2.7 Mode 1: Monitoring settings" on page 41▪ "7.2.8 Mode 2: Field settings" on page 427.2.2 Field setting componentsLocation of the 7‑segment displays, buttons and DIP switches:a bBS1 BS2 DS1 DS2BS3X27ABS1 MODE: For changing the set modeBS2 SET: For field settingBS3 RETURN: For field settingDS1, DS2 DIP switchesa 7‑segment displaysb Push buttons
