Series 2000 Vane Axial Heater
OPERATING PROCEDURE
Normal Operating Displays With Heater Not Running
The heater display with fan on (airflow).
When drying is not occurring, and the limit
or error condition is corrected, the display returns
to its normal output. This is not the case with an
error or limit condition during the drying opera-
tion. This causes the display to lock up in the er-
ror display mode. This is to keep the display
locked up with the condition illuminated. ( see
section on "Running the Dryer" for mode expla-
nation on page 17).
The main display shows the plenum temperature. If
the dryer has not been running, the display should
show outside temperature. The control is preset at
the factory to display temperature in centigrade or
fahrenheit.
"AIRFLOW" or "NO AIRFLOW" is displayed
if air is flowing or not flowing. "RX TX" (receive,
transmit) is displayed if multiple heaters are con-
nected.
All safeties or high limits are continuously
checked during the off mode. A limit switch open,
or any other error condition will cause the display
to show the limit or error condition.
