We have just updated from IQAN 3.19 to IQAN 4.06.
We are now seeing over load errors on several solenoids being controlled with PWM out signals.
The overloads only occur when the outputs are off. When they are on (90% Duty cycle) the errors go away.
I believe I remember reading something about circuit failure detection being active even when outputs are off as part of an IQAN 4 update.
Any recommendations on how this could be resolved?
