All error messages cause the ST315 to terminate the firing with all the
keys locked. An alarm buzzer sounds once per second.
SWITCH KILN OFF!
To reset the ST315 turn off the power to the instrument and have the fault
investigated by your installer or kiln service engineer to rectify the fault.
Technical note: any error message will cause the auxiliary alarm relay
(if fitted) to open—see installation handbook for details.
Note: these error messages are provided to detect kiln faults and so offer
some protection to the kiln. For increased protection the use of a heat fuse
or other independent over-temperature trip is recommended—such as the
Stafford Instruments ST101.
Error 7. Maximum room temperature
exceeded. The internal temperature of the
ST315 has exceeded an installer
selectable (30—70°C) limit.
