6. In the programming mode, the number of keys can be used to jump to menu levels without scrolling through
them ALL. I.E., from 0 select Model in “DRYER SETUP”; you can jump to menu level five (5). Enter lint
count under “DRYER SETUP” by pressing the five (5) key followed by “START/ENTER” l key to
accept value. Light emitting diode (L.E.D.) display will read five (5): ENTER Lint Count 1 to 5.
7. The basket (tumbler) temperature can be displayed by pressing and holding the “UP ARROW” key.
8. The programmed cycle parameter can be viewed by pressing the “START/ENTER” l key followed by
the “A-F” key. To view “0-40” cycles, press “START/ENTER” l key followed by the number desired to
view followed by “START/ENTER”
l key. The viewing can be stopped by pressing the “STOP/CLEAR”
O
key at anytime.
C. REV 2.2 FIRE SUPPRESSION SYSTEM (F.S.S.) THEORY OF OPERATION
Twenty-seconds after the heat turns off, the Phase 7 control monitors the F.S.S. probe located in the top of the
basket (tumbler) chamber and records the minimum temperature. If the minimum recorded temperature is no
less than 120° F (48° C) and the control detects a 35° rise in temperature, this will be the trip point and the F.S.S.
routine will activate.
While a drying cycle is in process and the heat is on, the Phase 7 control monitors the exhaust temperature
transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and the control detects
an exhaust temperature rise 25° F (13.8° C) greater than set point, this will be the trip point and the F.S.S. routine
will activate.
Once the F.S.S. routine is activated, water will be injected into the basket (tumbler) chamber. Anytime water is
being injected into the basket (tumbler); the basket (tumbler) drive will turn the load for 1-second every
15-seconds. This process will continue for a minimum of 3 minutes. After 3 minutes has elapsed, the control will
check if the temperature remained above trip point, if so water will remain on. The control will continue to check
if temperature is above trip point every 30-seconds. If the water has been on for a constant 10 minutes, the
water will be turned off regardless of the temperature. If the temperature has dropped below trip point, the
control will turn off the water prior to 10 minutes.
If a short or open F.S.S. Probe is detected after the F.S.S. routine has been activated, the water will remain on
for a minimum of 10 minutes then turn off regardless.
