DNFT-LED P/N:000506|Digital No-Flow Timer (DNFT) premier|Whitlock Instruments

DESCRIPTION
The DNFT-LED is a totally enclosed electronic device , combining the latest technology in microprocessor and transist or 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. 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 operato r to easily set and monitor lubrication rates.

OPERATION
Lubricant flow through the divider valve assembly forces the pistons to cycle back and forth causing a lateral movement o f a magnet linked to the piston. Movement is monitored by the microprocessor which resets the timer, lights the LED, and allows the uni t to continue operation, this indicates one complete cycle of the lubrication system. The microprocessor must receive this cycle in a predetermined time or a shut down will occur. The DNFT will automatically reset alarm circuit when normal operation of divide valve resumes.
