Usage of Relay B
Quality-relay
Flame Temperature-relay
Core Temperature-relay
8VZZ005286 B
Relay B can be used as a flame quality relay. In this case, it energizes when the
calculated quality is equal or above the programmed quality threshold and
de-energizes if the calculated quality is below the programmed quality
Relay B can be used as flame temperature relay (for pyrometer sensor only). In this
case, it needs to set a threshold above which the safe relay closes and below which
it opens
Relay B can be used as internal temperature relay. In this case, it energizes when
the temperature inside the enclosure is normal, and it de-energizes if the temperature
becomes abnormally high (but the module is still safe to operate)
