5. Hi-Limit Controller
The dryer utilizes six (6) channel controller (HLC-1) to monitor various locations on the dryer for over
temperature faults. The hi-limit controller enables the dryer to continually monitor up to six (6) Resistive
Temperature Devices (RTD's) at one time. Each channel is individual with set points. The hi-limit controller
scans each channel, and in the event of an alarm, the scanning will halt (stop), and the Single-Pole-Double-
Throw (SPDT) will change states signaling a fault. The hi-limit controller will remain in alarm until the reset
button is pushed and the temperature has fallen below the set-point temperature. The scan rate can be
adjusted from 4 to 12-seconds per channel.
• Channel #1 is used to monitor the exhaust for an over temperature situation.
• Channel #2 is used as an over burner monitor (for Gas Models Only).
• Channel #3 is used to monitor intake temperature (for Gas Models Only).
• The remaining channels are spares that can be used for future expansion.
