ERROR 9
Maximum allowable differential temperature between zones
exceeded. The temperature of zone 2 or zone 3 has varied from
zone 1 by an installer selectable limit.
All these error messages cause the ST535 to terminate the firing.
The alarm buzzer will sound once per second.
To reset the ST535 turn off the power to the instrument and have
the fault investigated and rectified by your installer or kiln service
engineer.
Note: these error messages are provided to detect kiln faults
and so offer some protection to the kiln.
ERROR P
Program Error. This error message is displayed
if a potential error is detected within the firing program when the

key is pressed to start a firing.
The alarm buzzer will sound 3 times and the segment display will
show the suspect segment number.
To clear this error press the
▶
key. The ST535 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
▶
key again to force 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.
