The DNFT-LED is a totally enclosed electronic device, combining
the latest technology in microprocessor and transistor
components for detecting Slow-Flow and No-Flow of divider block
lubrication systems. The DNFT incorporates an oscillating crystal
to accurately monitor the cycle time of the lubrication system to
enable precision timed shutdown capability. The magnet
assembly and control housing mount directly to the divider valve to
become an integral part of the lubrication system. The DNFT
operates on a field replaceable lithium battery. If battery voltage
drops below normal operating levels the DNFT goes into alarm
mode and the unit cannot be restarted. LED models utilize an LED
to indicate each cycle of the divider valve. This enables the
operator to easily set and monitor lubrication rates.
Lubricant flow through the divider valve assembly forces the
pistons to cycle back and forth causing a lateral movement of a
magnet linked to the piston. Movement is monitored by the
microprocessor which resets the timer, lights the LED, and allows
the unit to continue operation, this indicates one complete cycle
of the lubrication system. The microprocessor must receive this
cycle in a predetermined time or a shutdown will occur. The
DNFT will automatically reset alarm circuit when normal
operation of divider valve resumes.
