Good day to all,
I have a DC starter having 300 VDC as input supply and a 1.1 Kohm resistor connected in series to it. After the 1.1 Kohm resistor are 04 x time relays connected in parallel with a 24 VDC Zener diode to regulate the voltage. There is also a 470 uF 40V Capacitor connected in parallel with the Zener diode. When the whole circuit is power up, the time relays are getting 24 VDC and then raising to 64 VDC instead of a constant 24 VDC.
Is the 40V capacitor suppose to charge up the time relays at the same time when the zener diode is regulating the voltage at 24 VDC?
Can the capacitor be taken out so that the voltage to the time relays be maintain at 24 VDC?
Attached is the circuit diagram and very much thanks for the help
