ZONE (Zone Control Options)
Zone control is a feature that comes standard on the high-fire KM1627PK kiln and is availalbe as an
upgrade on the KM1227PK and KM1231PK kilns. Zone Control is feature that allows the controller to
independently fire sections on multiple section kilns to ensure even temperature top to bottom.
There are three optional setting configurations for Zone Control which can be accessed through the
“ZONE” feature under the “CNFG” menu:
●
NOTC
●
PId
● SHTO
NOTC (Number of Thermocouples)
• Your kiln should be properly programmed for the correct number of thermocouples before it leaves
the factory. All KilnMaster kilns will be set at 1 thermocouple except the high-fire KM1627PK which
comes standard with Zone Control. You cannot set a kiln to fire in more than one zone unless it is
configured in the factory as a Zone Control kiln. If you try, you will receive a “FAIL” error code.
• To change the number of zones on a zone control kiln, access the “ZONE” setting through the “CNFG”
menu, then use the menu key to toggle to the “NOTC” feature and press
ENTER
. The controller will
display the current “NOTC” setting. Input the desired value and press
ENTER
.
PId (Proportional Integral Derivative)
• PId is a zone control setting that uses the center section elements to help the bottom and top sections
when necessary. In most kilns the center section is usually the hottest section. The PId option is
designed to help speed up the firing when the top or bottom section is cooler and lagging behind the
other sections.
• When the top or bottom section is on full power (it is lagging behind), then output 2 comes on as a
percentage of output 1 or output 3. The middle section will then fire hotter and help the top and or
bottom section catch up. The percentage can be set from 0 (zero) to 150. It is factory preset at 85%.
SHTO (Shutoff)
• Shut off is a zone control feature that attempts to make firings more consistent. For 2 and 3 zone
controllers, when shutoff is “OFF”, the controller uses the average of all three thermocouples to
transition from one segment to the next or to shut off the kiln. When “ON”, the kiln turns off or
transitions when any one of the thermocouples reaches temperature. FOR ALL DOWN RAMPS, the
controller transitions from one segment to the next as if shut off ”SHTO” were turned “ON”, ie., when
any one section reaches the next segment temperature.
Id (Control Interface System ID)
CIS is an optional accessory that allows you to program and monitor multiple kilns from a PC. Each
kiln hooked up to the CIS system needs to be identified with a unique number so the software can
distinguish it from the other kilns. To set the identifying CIS number for each kiln, access the “Id” set-
ting through the “CNFG” menu, select a number between 1 and 99 and press
ENTER.
OUT4 (Output 4 Settings)
There are three standard outputs, one safety output and one accessory output on your Skutt
KilnMaster controller. The accessory output is designated as Output 4 and can control a number of
optional accessories including vents, alarms and autodialers. Output 4 will cycle these accessories
on and off at different times depending on the program you are running and the way you configure
it under the “OUT4” feature setting. There are five different options for OUT4.
