All these error messages cause the ST216 to terminate the firing. The alarm buzzer
will sound once per second. To reset the ST216 turn off the power to the instrument
and have the fault investigated and rectified by your installer or kiln service engineer.
Technical note: these error messages will cause the alarm relay
to open.
Note: these error messages are provided to detect kiln faults
and so offer some protection to the kiln.
Maximum firing time exceeded. The length of
the firing has exceeded an installer selectable

program when the
► n

firing. The alarm buzzer will sound 3 times and
the PROGRAM display with flash with either the
current program number, or the number of the faulty program within a linked se-
quence. To clear this error press the
► key. The ST216 will now enter programming
mode to allow the suspect program to be viewed and altered if necessary. If a fault is
found then correct it. If no fault is found then press the

firing program to start. A potential programming error is defined as a very low ramp
rate to a very low temperature. Such a programming fault might cause very long firing
times with potential kiln damage.
