Q.  How does the alarm relay operate with setpoints in a multi-head system?

A.  Consider a scenario where the Tobj setpoint for Head 1 is set at 200 deg C and that of Head 2 is set at 220 deg C


1. When the Head 1 measures temp equal or in excess of 200 Deg C, the alarm relay activates. 
2. If Head 1 continues to measures in excess of 200 Deg C & Head 2 measures in excess of 220 Deg C, the alarm relay will stay active.
3. If Head 1 temperature drops below 200 Deg C, but Head 2 temperature is still above 220 Deg C, the alarm relay will still stay active.
4. If Head 1 temp drops below 200 Deg C & Head 2 temp drops below 220 Deg C, the alarm relay will turn OFF.
