DESCRIPTION OF LINT FILTER OPERATION
Your new Energenics Lint Filter operated with a UL approved control represents the
most advanced features available in the laundry industry to date. The following list
the functions and mode of operation:
Blowdown (cleaning) – The Lint Filter will monitor the system backpressure and
automatically initiate the blowdown cycle. As the screen loads with lint the lint, the
back pressure will increase and will result in an automatic blowdown (cleaning) when
the backpressure reaches a set reference (default is .5” w.c.). The lint filter wills also
blowdown every 30 minutes to insure complete screen cleaning when dryers are
turned off. The setting can be adjusted by the operator by changing program values
in the PLC. 70% of the lint will be removed from the screen even though the dryer(s)
may be operating. During the timed blowdown with dryers off, 100% of the lint will be
removed from the screen. A manual blowdown can also be done by depressing the
button on the bottom of the Lint Filter control. Note that automatic blowdown
cannot occur within 3 minutes of a prior blowdown. This is done to allow the
compressed air supply to fully recover.
Optional Excess Pressure Alarm – If for any reason the Lint Filter has not blown down
properly (i.e.: compressor turned off) the system will sense a higher backpressure
than normal. The excess light on the filter control and the siren and the strobe light
both activate. The Filter control will attempt to blowdown every 3 minutes until the
excess backpressure condition has terminated. If this condition persist a manual
inspection of the lint screen and observation of proper blowdown must be done.
Optional Fire Control System – A normally open sensor located inside of the filter at
the top of the inlet will close at 360 degrees F. The control will open the water
solenoid, illuminate the strobe as well as energize the siren. The Alarm will be active
until 30 seconds after the temperature has dropped bellow 360 degrees F. After 30
seconds the alarm will automatically reset. Inside the control box is a Fire Control
test button. Depress the button and the Fire Control will be activated for 30 seconds.
The function of the test button is to check the circuit. It does not test the sensor itself.
Using a propane torch to the sensor will test the complete system.
