American Dryer Corp MDG-120PVV, MD-170PTVW Fire Suppression System Theory of Operation

Page 49

WARNING: If the water in the supply line or water solenoid valve freezes, the fire suppression system will be INOPERATIVE!!

The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it is easily accessible.

3.Electrical Requirements

No independent external power source or supply connection is necessary. The 24-volt power to operate the fire suppression system is accomplished internally in the dryer (from the dryer controls).

WARNING: Electrical power must be provided to the dryer at ALL times. If the main electrical power supply to the dryer is disconnected, the fire suppression system is

INOPERATIVE!!

FIRE SUPPRESSION SYSTEM THEORY OF OPERATION

While the dryer is in an idle state, or 20-seconds after the heat turns off, the microprocessor controller (computer) monitors the thermistor probe, located in the top of the basket (tumbler) chamber, and records the minimum temperature. If the minimum recorded thermistor probe temperature is greater than 120° F (48° C) and the microprocessor controller (computer) detects a 50° rise in temperature, this will be the trip point and the fire suppression system routine will activate.

While a drying cycle is in process and the heat has turned on at least once, the microprocessor controller (computer) monitors the exhaust temperature transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and the microprocessor controller (computer) detects an exhaust temperature rise 25° F greater than set point, this will be the trip point and the fire suppression system routine will activate. If set point is below 160° F (71° C), the trip point will be 185° F (85° C).
