2. If the Output Light (C1) on Digital Controller
is lit.
A. Check the solid-state relay on panel.
B. Check airflow through process air hose.
Check the alarm limit first, by pressing and
holding the
SEL
button on the temperature
controller until
STBY
is displayed. Then press
the DOWN arrow key until AL1 is displayed in
the upper (PV) display. The setting displayed in
the lower (SV) display indicates the number of
degrees over the set point that the alarm will be
actuated. It is factory set to 50
°
F (30
°
C) and
should not be set below 30
°
F (16
°
C) or it will
actuate too quickly.
If the temp exceeds the set point, check the following:
1. Remove the hose from the top of the hopper
to check airflow. There should be airflow out
of the hopper exhaust port and a vacuum on
the hose. If there is little or no flow, check
the inlet hose.
2. Inspect the filter to make sure that it is clean
and not affecting the airflow.
3. Check the to see if the solid state relay has
failed on by using a multi-meter on the
output to the heater. The relay has failed if
there is power to the heater when the Solid-
state relay’s input power is not activated.
If thermocouple has failed, check following:
1. Ensure thermocouple plug is securely inserted
into dryer outlet.
2. Check thermocouple continuity with multi-
meter.
