The MX920/921 employs some unique features in its
design and much thought and consultation has been used to provide a product that offers an
extreme degree of flexibility for the installer and service person. For example, all
options may be easily field retrofitted at a later date. A common chassis is used for both
vertical and horizontal version models. Batteries may be installed at two or both
locations in the chassis. Internal wiring has been simplified and cut by 90%. In addition,
servicing is simplified with one single main PCB having all components on one side of the
PCB. This permits the Technician to diagnose problems while either
still connected in the chassis or powered simply and independently on the test bench. The
flexibility of the MX920/921 series allows it to be configured for a wide range of
applications without removing any covers. |
