The primary display looks like above image, breakdown the dipslay into 4 sections, section 1, section 2, timer 1 and timer 2
Section 1 is the PID control loop, which displays the process value and setting value and various status indication, like AU1,AU3, AU4, AU5 relay energization.
Section 2 is display for safety Limit Controller purpose with a latching relay output(AU2), and a cross comparison between the reading pick up from sensor 1 and sensor 2, once the undesirable limit reached, the AU2 relay will be triggered and it requires a manual reset.
Timer 1 is the count down timer for the temperature holding time range, when PV reach to SV, the timer will engage automatically and count down process begin
Timer 2 is the count down timer for the circulation fan, for most of oven, there will be significant heat inside the chamber even after the heater stops to work, in this case, it is essential to keep the circulation fan running for certain period of time, the circulation fan kicks-in as long as you hit the RUN button and starts the heating process, but it won't stop at the point when program ends, instead, it will keep running for some time, when heating terminated, the count down timer for circulation fan starts to ticking down and after timer elapsed ,then the fan will be shut down.
