PROBLEMS WITH THE CONTROLLER
Connection errors and inadequate programming are the most common
errors found during the controller operation. A final revision may avoid
loss of time and damages. The controller displays some messages to
help the user identify problems.
: Sensor measuring temperature below the specified
minimum.
: Sensor measuring temperature above the specified
maximum.
: Controller failure or sensor error, examples: Thermocouple
open, Pt100 open in short circuit or poorly connected.
If the “Error” message persists after analysis of the
installation, contact manufacturer informing equipment’s
Serial Number.
FINDING THE CONTROLLER’S VERSION AND SERIAL NUMBER
When the controller is turned on, it shows on its displays for three
seconds its version (review). To see the serial number turn the
controller on holding the
key.
This information is necessary for eventual contact with the controller’s
manufacturer.
