Access protection. All Stange program controller dispose of a multilevel access protection. It can be switched with the PLC an therefore with particular situations. If e.g. a process recipe is beneath execution it is feasible to abort with a keypress but it is not potential to use this functionality during execution an abort recipe.
Other choices. These are the options which we only knew few customers did.
1) Use SSR instead of contactor. SSR will provide a extra precision management. Nevertheless it wants heat sink to remove the heat generated from the SSR. This is straightforward for oven that attracts lower than 20A of current. Because most power coating oven requires more than 60 Kws heater, it makes heat elimination more difficult. A cooling fan may be needed to blow over the heat sink. When use SSR, you need a Range hood controller with SSR control output. Both our SYL-2352 or the SYL-2362 can be used.
2) Some people put a timer in the control loop. They use the alarm to activate the timer when temperature reaches the alarm setting. When timer attain completed, it’ll flip off the contactor to shut off the system.
— In most such instances, the fault error code will seem on the small display but when this doesn’t happen then you could verify for energy to the elements.
— Nonetheless if there isn’t a energy to the weather then in that case it’s essential to examine for the control board with a view to confirm that there is power at the appropriate output relay. I
— f you discover no output then you will need to get the electronic control board replaced.
— The voltage checks executed at the management board are live voltage checks and it is best that you contact an expert technician to do these checks for you.
— Moreover for doing so, you may need applicable meters or gadgets which professionals have but you might not.
