XWEB WITH
SCROLL CONDENSER UNITS
Installation Instructions: XJ Scroll
Condenser to XWEB300D/500D/500
Copeland XJ Scroll Condenser Units are used for walk-in cooler and freezer applications. All units
integrate the many benefits of scroll compressor technology, fan speed control, and
Copeland PerformanceAlert™ diagnostic controls.
XWEB communicates with the Copeland XJ Scroll Condenser One-way Communication Board
via the RS485 MODBUS network. The XWEB is used to receive alarm and notice status from the
XJ Scroll condensers via the One-way Communication board. If the XJ Scroll condenser does not
have a One-way Communication Board, one must be installed for XWEB alarm and notice
receiving. The XWEB then provides the ability to assign delays and priorities to alarms or
notices, but the alarms and notices can be logged in the XWEB.
