USER SAFETY
The DFX employs modular construction and provides electrical safety for the operator. The enclosure is
constructed from rugged polycarbonate plastic with UV inhibitors. The enclosure does not contain any
conductive materials that can become energized while the door is closed. The keypad is also manufac-
tured from polycarbonate and is designed for outdoor use. The AC power transformer provides 4,000
Volts of isolation from the power supply mains. The display face contains voltages no greater than 24
VDC. Output modules are optically isolated from external power supplies and provide a great degree of
immunity to ground loops.
CAUTION: If the DFX is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
DATA INTEGRITY
The DFX product retains all user configuration data and totalizer accumulations in non-volatile FLASH
memory indefinitely.
PRODUCT IDENTIFICATION
The serial number and complete model number of the transmitter are located on the side of the moni-
tor enclosure. Should technical assistance be required, please provide the Customer Service Department
with this information.
