American Dryer Corp ADG-530 technical manual Terminal Designations

c)Flame Failure “Reignition”

If the established flame signal is lost while the burner is operating, the HSI module (controller) will respond within 0.8 seconds. The gas valve will be de-energized, the HSI module resets and starts a new ignition sequence in an attempt to relight the burner. If the burner does not light, the HSI module will de-energize the gas valve. The HSI module will make two (2) more attempts to relight the burner. If the burner does not relight the HSI module will go into the LOCKOUT MODE. If the flame is reestablished, normal operation resumes.

The “red” L.E.D. (light emitting diode) will flash on for a 1/4 second, then off for a 1/4 second during a fault condition. The pause between the fault codes is three (3) seconds.

NOTE: To reset the HSI MODULE if it is in the LOCKOUT MODE or the FLAME SENSOR FAULT MODE, open and close the main door then restart the dryer.

3)HSI (Hot Surface Ignition) Module

The HSI module (controller) utilizes a microprocessor to continually and safely monitor , analyze, and control the proper operation of the gas burner. Additional features consist of L.E.D. diagnostics, automatic one (1) hour reset, multiple tries, and flame current testing pins highlight the HSI module benefits.

The terminal designation that are listed below correspond to the designations on the bottom portion of the HSI module (as shown from left to right).
