The Fusion4 Local Access Device (LAD) is an intrinsically safe handheld controller used to commission, configure, calibrate, troubleshoot and transfer data with Fusion4 SSC-A, SSC-B, MSC-A and MSC-L devices. It navigates device menus, adjusts parameters, resets alarms and calibrates injectors, and provides two-way data transfer of transactions, configuration files and calibration records. Firmware for Fusion4 devices and the LAD itself can be upgraded in the field, and a removable SD card makes it easy to move data to a safe area. It is certified for Class I, Division 1 / Zone 1 hazardous areas.
