#165897 - situation under control Responding to: ???'s previous message |
Yes low voltage components need all the protection from the "dirty" noise glitches from highvoltage compoenets like motors, solenoids etc.
Right now I have eliminated the problem almost to a non-existent level : There was a thermostat that was switching on the cooler motor relay and that relay had no free wheel diode earlier. Now it has. Introduced a three phase snubber network acroiss the motor terminals. With the above remedies, the MCU does not get reset as earlier but only very, very occassionaly. And I also know one thing for sure : Right now I have completed 300,000 cycles and the client is visiting me on Wednesday, when I will complete 1 million cycles. And the MCU sure WILL reset in front of him !! Raghu |
