If the preset parameters on the controller have been tampered with
and it no longer properly controls temperature and displays dew
point, you can restore the controllers to the factory setup. Call the
Service Department at AEC for detailed instructions.
The E5CN controller has several mode selections. Within each
mode are numerous parameters that can be set.
The factory at AEC sets the security level to protect the critical
parameters from being accidentally changed. Below is an
explanation of the operating modes you will have access to and the
AEC default settings.
When "RUN" is selected, the control is running. When "STOP" is
selected, the control is stopped. When the control is stopped, the
STOP display lights. The default is set to "RUN."
This setting is used to indicate how many degrees the process
temperature will be allowed to exceed the set point temperature.
An alarm output will de-energize the heaters.
This feature is used to automatically set the optimum PID
parameters "proportional band," integral time" and "derivative
time" for the set point value by changing the variables which had
been modified previously.
This setting is used to offset an error between the set point and the
actual temperature. The entire input range is shifted by a set figure
preprogrammed by the operator.
