◦Solution: Check parameter ID3 to make sure that the correct scale was selected
• Compare service value ID34 to the value reported to be the output from the control system. If necessary, measure
the actual current into the ICAD
◦Solution: If the two values do not equate, check wiring, paying special attention to wire polarity. If measured mA
does not equate to the stated controllers output, the problem is likely to be in the control system. If measured
mA does not equate to the value seen in ID34 and everything is wired properly, the problem is likely with the
ICAD actuator
• The ICAD was not mounted properly on the valve stem
◦Solution: Check to make sure that the ICAD set screws are evenly torqued around the base of the ICAD
The valve does not appear to be opening fast enough or seems too fast
• The speed of the ICM valves are preset at the factory:
◦For ICM valves 20, 25, and 32, the preset speed is 100%
◦For ICM valves 40, 50, 65, 100, 125, and 150, the preset speed is 50%
• Solution: Check parameter ¡04 to note the actual setting and adjust accordingly
The valve position feedback signal is not working with the customer supplied controller/PLC
• A power supply was installed in the 4–20 mA/0–20 mA feedback loop. The ICAD motor actuator supplies power for
the 4–20 mA/0–20 mA feedback loop
◦Solution: Remove any power source that may be supplied to the feedback loop
• Wiring problem
◦Solution: Check the service value of ID36 (the analog output signal) to see what the ICAD is outputting. If
nothing is revealed, check the output wire (blue) with an ammeter to verify the actual output value.
• The feedback output signal was not turned on in parameter ID18
