8. RDRO – (RED L.E.D.) This L.E.D. will indicate the status of the Rear Doors. If the doors are open,
then the L.E.D. is ON.
9. FAN – (RED L.E.D.) This L.E.D. will indicate the status of the Blower Fan. If the fan is on, then the
L.E.D. is ON.
10. RBHL – (RED L.E.D.) This L.E.D. will indicate the status of the Rear Burner Hi-Limit Disk. If the
disk is closed (Temperature below 330º F [166º C]), then the L.E.D. is ON.
11. R_SS – (RED L.E.D.) This L.E.D. will indicate the status of the Rear Sail Switch. If the switch is
closed, then the L.E.D. is ON.
12. FBHL – (RED L.E.D.) This L.E.D. will indicate the status of the Front Burner Hi-Limit Disk. If the
disk is closed (Temperature below 330º F [166º C]), then the L.E.D. is ON.
13. F_SS – (RED L.E.D.) This L.E.D. will indicate the status of the Front Sail Switch. If the switch is
closed, then the L.E.D. is ON.
14. EXHL – (RED L.E.D.) This L.E.D. will indicate the status of the Exhaust Hi-Limit Disk. If the disk is
closed (Temperature below 225º F [107º C]), then the L.E.D. is ON.
15. DRY – (RED L.E.D.) This L.E.D. will indicate the status of the Programmable Logic Controller (PLC).
If the mechanical functions of the dryer have been set to the DRY position, the
PLC will send a signal to the Phase 7 board. This signal will indicate that ALL
the doors are closed and the dryer is level. When these conditions are met, then
the L.E.D. is ON.
16. LINT – (RED L.E.D.) This L.E.D. will indicate the status of the Lint Drawer. If the drawer is closed,
then the L.E.D. is ON.
17. R_HE Supply power for rear heat output (optional).
18. F_HE Supply power for front heat output.
19. 24VM – (RED L.E.D.) Control voltage at the spare inputs.
20. FVLV – (RED L.E.D.) This L.E.D. will indicate the status of the Front Gas Valve. If the Front Gas
Valve is open (ON), then the L.E.D. is ON.
21. RVLV – (RED L.E.D.) This L.E.D. will indicate the status of the Rear Gas Valve. If the Rear Gas
Valve is open (ON), then the L.E.D. is ON.
22. SPR1 – (RED L.E.D.) This is for a spare input to be used with programmable outputs.
23. SPR2 – (RED L.E.D.) This is for a spare input to be used with programmable outputs.
24. SPR3 – (RED L.E.D.) This is for a spare input to be used with programmable outputs.
25. SPR4 – (RED L.E.D.) This is for a spare input to be used with programmable outputs.
26. SPR5 – (RED L.E.D.) This is for a spare input to be used with programmable outputs.
27. +24 – (RED L.E.D.) This L.E.D. will indicate the board voltage that is protected by Fuse #2.
28. 24IN – (RED L.E.D.) This L.E.D. will indicate 24 VAC to the board.
29. MCR+ - (RED L.E.D.) This L.E.D. will indicate the status of the Control Voltage. If the Power On
button is pressed (Green Button Light is On), then the L.E.D. is ON.
