hi guys,
got a problem with some timer switches(220VAC,24VDC).
the problem is that they seem to work at times but sometimes not.
They are on-delay timers , so after some pre-selected time the normally closed switch should open and the normally open should close and all this happen when the timer is supplied with voltage,and to re-initialise them the voltage should be removed.what actully happen is that when its time for the switch to close or open it just oscillate from closed to open position twice or sometimes thrice and then regain its normal behavior.
There is a 16-stage binary counter(MC14541BCP) and a transistor(C5468, by the way someone have its datasheet? ive searched but not found.) which i think might be causing this.the timer works also with dc supplies(24V),and it works perfectly.Someone have an idea what might be causing this?
