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.
