Purpose: To run an automotive fan in the forward & reverse direction. The test cycle is "Forward direction ON - 1.5min, OFF - 1.5sec, Reverse direction ON - 1.5min, OFF - 1.5sec. It is a continuous process till you see some failure.
Test Equipments: 2 DC power supplies, 1 DPDT solenoid (for forward & reverse mode), 1 Omron Timer relay H3CR-F8-300, 1 Relay SPST-NO-DM 4 pins 12VDC (Dayton 5z550), 1 10A fuse, 1 50A shunt.
Test Set Up: I am using a DPDT solenoid to reverse the polarity. I am using an Omron relay timer to control the cycle time. I am able to reverse the polarity but the time period of switching the polarity is less than 10th of a second.
How can I increase the time delay to 1.5sec before the DPDT solenoid reverses its polarity?
Any help much appreciated.
Cheers!!
P.S.: I know the drawing is very rudimentary and I am trying to make a proper schematic.
