63When the ATTACH TO NETWORK DEVICE screen is ac-cessed, information can not be read from the ICVC on any de-vice (including the local chiller) until one of the devices listedon that screen is attached. The ICVC erases information aboutthe module to which it was attached to make room forinformation on another device. Therefore, a CCN module mustbe attached when this screen is entered.To attach any CCN device, highlight it using thesoftkey and press the softkey. The message “UP-LOADING TABLES, PLEASE WAIT” displays. The ICVCthen uploads the highlighted device or module. If the moduleaddress cannot be found, the message “COMMUNICATIONFAILURE” appears. The ICVC then reverts back to the AT-TACH TO DEVICE screen. Try another device or check theaddress of the device that would not attach. The upload processtime for each CCN module is different. In general, the upload-ing process takes 1 to 2 minutes. Before leaving the ATTACHTO NETWORK DEVICE screen, select the local device. Oth-erwise, the ICVC will be unable to display information on thelocal chiller.ATTACHING TO OTHER CCN MODULES — If thechiller ICVC has been connected to a CCN network or otherPIC controlled chillers through CCN wiring, the ICVC can beused to view or change parameters on the other controllers.Other PIC II chillers can be viewed and set points changed (ifthe other unit is in CCN control), if desired, from this particularICVC module.If the module number is not valid, the “COMMUNICA-TION FAILURE” message will show and a new address num-ber must be entered or the wiring checked. If the module iscommunicating properly, the “UPLOAD IN PROGRESS”message will flash and the new module can now be viewed.Whenever there is a question regarding which module onthe ICVC is currently being shown, check the device name de-scriptor on the upper left hand corner of the ICVC screen. SeeFig. 19.When the CCN device has been viewed, the ATTACH TONETWORK DEVICE table should be used to attach to the PICthat is on the chiller. Move to the ATTACH TO NETWORKDEVICE table (LOCAL should be highlighted) and pressthe softkey to upload the LOCAL device. TheICVC for the 19XR chiller will be uploaded and default screenwill display.NOTE: The ICVC will not automatically reattach to the localmodule on the chiller. Press the softkey to attach tothe LOCAL device and view the chiller operation.Service Operation — An overview of the tables andscreens available for the SERVICE function is shown inFig. 21.TO ACCESS THE SERVICE SCREENS — When theSERVICE screens are accessed, a password must be entered.1.
