DESCRIPTION
The DNFT-PRG-PS 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 precisely 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-PRG operates on field replaceable lithium battery. If battery voltage drops below normal operating levels, the DNFT goes into alarm mode and the unit cannot be restarted. The PRG utilizes a LED to indicate each cycle of the divider valve. This enables the operator to easily set and monitor lubrication rates. The PRG comes with a liquid crystal display to display total pints, cycle time of divider valve, total cycles of divider valve, and pints per day pump rate. The PRG can easily be programmed for an alarm time from 20 seconds to 4minutes 15 seconds. The DNFT has been designed and rated for use in Class I Zone I environments, to be used outdoors in wet or dry locations, in altitudes under 2000 meters, with a Pollution Degree of 4.
OPERATION
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.
