Programming the ICAD
When the ICAD motor is first powered, the ICAD display will flash an A1 alarm. This means
that the ICM valve size that is being used with the ICAD motor needs to be selected in
parameter
¡26
. Parameter
¡26
is password protected and will not appear in the parameter list
until the user enters the password in parameter
¡10
. The password is “11,” and will allow the
user to access parameter
¡26
where the appropriate valve size is selected. When the ICM
valve size is selected, the ICAD will calibrate itself to the ICM valve and will then be ready for
control by a 4-0mA signal. For most applications, this is the only programming that will
need to be done if the ICAD is going to be controlled by a 4-0mA input.
