Electrical Requirements
No independent external power source or supply connection
is necessary. The 24 volt power to operate the S.A.F.E. system
is supplied internally from the dryer control.
Warning
Electrical power must be provided to the dryer at all
times. If the main electrical power supply to the
dryer is disconnected, the S.A.F.E. system is
inoperative!!
S.A.F.E. System Theory of Operation __
While the dryer is in an idle state or 20-seconds after the heat
turns off, the Phase 7 control monitors the S.A.F.E. system
probe located in the top of the basket (tumbler) chamber and
records the minimum temperature. If the minimum recorded
S.A.F.E. system probe temperature is greater than 120° F
(48° C) and the control detects a 50° rise in temperature, this
will be the trip point and the S.A.F.E. system routine will
activate.
While a drying cycle is in process and the heat has turned on
at least once, 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 greater than set point, this
will be the trip point and the S.A.F.E. system routine will
activate. If set point is below 160° F (71° C) the trip point will
be 185° F (85° C).
Once the S.A.F.E. system routine is activated, the control will
display “S.A.F.E. System Activated” and 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 2 minutes. After 2 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 and the control will display “S.A.F.E. Was
Activated.” If the temperature has dropped below trip point,
the control will turn off the water prior to 10 minutes.
Disabled S.A.F.E. System
In the event that the S.A.F.E. system is not installed properly
or if there is a malfunction in the system the Phase 7 coin
control will notify the user by displaying the message “S.A.F.E.
DISABLED...” If the “PAUSE” and “LO” keys are
simultaneously pressed, the control will display one of the
following diagnostic messages indicating the fault with the
system. If there is more than one issue with the S.A.F.E.
system, the control will display one message at a time.
S.A.F.E. Diagnostic Messages
Open S.A.F.E. Probe Fault: This message indicates that the
S.A.F.E. probe is either not connected or is damaged.
Shorted S.A.F.E. Probe Fault: This message indicated that
the S.A.F.E. probe is damaged or the wiring is shorted.
Open S.A.F.E. Valve Fault: This indicates that the water valve
is open or that it is not connected to the control.
Shorted S.A.F.E. Valve Fault: This indicates the water valve is
shorted or the wiring to the valve is shorted.
Water Not Connected: This indicates that there is no water
pressure at the water valve. This will occur if water is not
connected to dryer or if there is low water pressure in the
water line coming to the dryer. This could also be a defective
pressure switch or wiring to the pressure switch.
System Reset __________________________
To reset the microprocessor once the control displays
“S.A.F.E. Was Activated,” press and hold the “PAUSE” key for
3-seconds.
