introductionThese instructions are intended to assure that field connections are completedproperly and the control system operates for the maximum time possible. Sinceproduct warranty may depend on your actions, please read these instructionsthoroughly prior to operation.If you have questions about the operation and/or maintenance of this controlsystem and you do not find the answers in this manual, please contact yourMarley sales representative.WarningHazard of electrical shock or burn. Be sure to turn off power to thepanel before servicing. If working on equipment out of site of paneldisconnect, lockout using standard lockout procedure.Safety FirstThe MarleyGard LINK uses UL listed components installed in accordancewith the National Electric Code. The location of the cooling tower and fieldinstallation of the control system can affect the safety of those responsiblefor installing, operating or maintaining the tower and controls. However,since SPX Cooling Technologies does not control the tower location, or fieldinstallation, we cannot be responsible for addressing safety issues that areaffected by these items.WarningThe following safety issues should be addressed by those responsiblefor installation, maintenance or repair of the tower and controls: Access to and from the control panel (including the customer suppliedmain disconnect/branch circuit protection) Proper grounding of electrical control circuits Sizing and protection of branch circuits feeding the control panel Qualification of persons who will install, maintain and service the electrical equipmentThese are only some of the safety issues that may arise in the design andinstallation process. Consult a safety engineer for additional guidance.Other safety issues are addressed in literature supplied with your tower. Youshould closely review the literature prior to installing, maintaining or repairingyour tower.3

installationThe communications module is BACnet compliant and programmed by Marleyfor job specific configuration. The LINK panel is available as an “add on box”integrated into a Marley cooling tower control panel system.Each LINK panel is serialized with a cooling tower order number located onthe inside door of the control panel. Refer to this number when addressingquestions or support with SPX Cooling Technologies.The MarleyGard LINK panel is compatible with Marley control panels: AIO control panel SPPC control panel CoolBoost control panel ABH control panelQuick Start Guide Mount LINK enclosure adjacent to a Marley control panel. I dentify job site points to monitor in the Marley control panel. Run 120VAC power wiring from the Marley control panel to the LINKpanel in separate conduit. Run conduit for status wires from the control panel to BACnet panel inseparate conduit. Seal conduit runs with expanding foam or silicone making a vapor barrierto prevent condensation. Spring clamp terminal block instructions: Strip field wire insulation back7/16". Insert small flat blade screw driver into the square hole then pushdownwards to release the internal wire clamp, while holding downwardinsert the field wiring then release the driver.6
installationSetup Programming The BAScontrol22C module used in the LINK control panel is preprogrammed according to cooling tower components status pointsselected for a project. Actual monitoring points may vary by projectrequirements for BMS monitoring. I P address, setup and descriptions may be changed in the field using aPC and RJ45 ethernet patch cable, software is not required. The defaultIP address is 192.168.92.68.
