STEP 7
Programming Current Sensing
The
835/836
circuit boards incorporate a safety feature that will put the op-
erator into a hard shutdown mode if the circuit board detects a current sense
two consecutive times during a cycle. This hard shutdown condition can only
be reset by shorting the
FIREBOX
or
UL
connectors on the left side of the cir-
cuit board to ground. If a firebox is used in the installation, The firebox door
should be opened and closed to reset the circuit board.
