Despatch Protocol Controller - Manual (Page 14)

WARNING: Never operate the
oven at a temperature in excess
of the maximum operating
temperature.
Protocol Hi-Limit
Protocol will not let the high limit value drop below the setpoint value. In certain
situations, it may be necessary to change the setpoint first and then adjust the high limit
value.
It will be necessary to reset the hi-limit whenever it
has tripped. The hi-limit may be reset by first
allowing the oven chamber to cool slightly (or
increasing the parameter by several degrees) and
pushing the Reset key. During a high limit condition
the Over Temp LED will turn on thus deactivating
the heater.
