FlowCon SM with SM actuator 1B95081 - 01/2019 Diagnosing repeated errors If actuator does not seem to use the correct range between open and closed, try starting an auto-stroke re-calibration (press and for 6 sec.). When the calibration is done, the actuator automatically returns to normal operation. If this does not solve the problem, turn off power to the actuator and turn it back on (all programming information is kept independently of power loss). If this does not solve the problem, start a recalculation of the positioning magnet by pressing and buttons simultaneously for 6 sec. and enter the password 3331433. When the calculation is done, the actuator automatically returns to normal operation. If error 05 (step D05) has occurred several times, it shows that the power supply is unstable. If the power supply cannot be stabilized fx. through maintenance of the wiring, failsafe is recommended. If atuator includes failsafe, check charges (step N) for indication on whether or when to have battery replaced. If error 06 (step D06) has occurred several times, it shows an unstable control signal. Check wiring for common and control signals. If error 08 (step D08) has occurred several times, either increase the refresh rate of the BACnet control signal or increase the BACnet Fallback Timeout (AV.143) parameter. If errors 01 & 02 (step D01 and D02) have occurred several times, it shows a tendency of the actuator getting stuck (and unstuck) repeatedly. This is probably due to either a lot of debris in the water or the valve having an error. In the first case flush the system and be sure to use water free from debris and/or consider installing several strains in the system; in the last case replace the valve with a new one. Only if actuator includes failsafe: If error 07 (step D07) occurs, send actuator to repair. If step G shows that the battery has been exposed to temperatures above +50°C (+122°F), the life time guarantee of 500 charges no longer applies. If errors 03 & 04 (step D03 and D04) have occurred several times, it shows a tendency of overheating in the area surrounding the actuator - check step G for the maximum temperature. Consider isolating the actuator from the heat or installing a cooling system near the actuator. If step G shows that the actuator has been exposed to temperatures above +80°C (+176°F), some electrical parts have likely been damaged by the heat. If step H shows that the battery has been exposed to temperatures below -20°C (-4°F), the life time guarantee of 500 charges no longer applies. If step N shows that the battery has been charged more than 500 times, the battery has reached the limit of its guaranteed life time and replacement should be considered. If step H shows that the actuator has been exposed to temperatures below -20°F (-4°F), some electrical parts might be damaged by the cold.
