E. SPRINKLER SYSTEM DESCRIPTION
The dryer’s sprinkler system is monitored by a microprocessor based temperature controller as a designated
“FAIL-SAFE.” The microprocessor circuit must have power in order to engage main power to the dryer. When
cycling the dryer, if temperature at the Resistive Temperature Device (RTD) reaches 575º F (301.6º C), one (1)
set of contacts in the controller will open, disabling the power (electric supply) to the dryer. Another set of
contacts will close, sounding the alarm and turning on the sprinkler.
NOTE: The sprinkler as well as the alarm will remain on until the “amber” colored sprinkler reset
button is pressed and the temperature in the basket (tumbler) falls below 575º F (301.6 º C).
1. Description Of Components
a. RTD
The RTD is located above the basket (tumbler).
The probe is a 100 ohms (100 Ω) platinum RTD.
As the temperature increases or decreases the
resistance value corresponds to the ambient
temperature (i.e., 100 Ω = 32º F [0º C]...109 Ω =
75º F [24º C]).
b. Sprinkler Valve
The sprinkler valve is a 2-way, air piloted, normally
closed valve. With pilot air pressure applied, the
valve opens allowing water to flow.
c. Sprinkler Solenoid Valve
The sprinkler solenoid valve is a 3-way/2-position
solenoid valve that is used to supply pilot air to
the sprinkler valve.
