So I had a couple of minute to check the above mentioned problem, this is what I observed:
1.When the HLT temp was above the set value, the SSR out as well as the SSR itself did not blink. Good
2.When the HLT temp was below the set value, the SSR out as well as the SSR itself did blink. Good
3. Once the set value had been reached, the SSR out as well as the SSR itself stopped blinking. Good
So from this, the PID seems to be working correctly, seems to be sending the signal to the SSR when it should be.
As soon as I turn the element on using the switch, the element kicks up and starts heating the HLT. Whether the SSR out is blinking or not, the element continues to fire. Even when I set it in manual mode at 0%, the element still fires....
So, if the SSR itself is blinking in synchrony with the SSR out, does this in any way tell me that the SSR is ok (not failed closed)?
Is there another possibility to this problem other than an SSR problem...perhaps a wiring mistake??
Thanks a lot for your help!!!
