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.
