ZONE (Zone Control Options)
Zone control is a feature that comes standard on the Production line of GlassMaster kilns. This line in-
cludes the following models: GM1227, GM1018, and the GM818. 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 3 optional setting configurations for Zone Control which can be accessed through the “ZONE”
feature under the “CNFG” menu..
A. “NOTC”
B. “PId”
C. “SHTO”
“NOTC” (Number of Thermocouples)
Your kiln should be properly programmed for the correct number of thermocouples before it leaves the fac-
tory. A GM818 and GM1018 should be set at 2 and the GM1227 should be set at 3. All other GlassMaster
kilns will be set at 1 thermocouple. You cannot set a kiln to fire in more than one zone unless it is config-
ured 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. Enter 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 percent-
age of output 1 or output 3. The middle section will 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 control-
lers, 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, i.e., when any one section reaches the next seg-
ment 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” setting through the
“CNFG” menu, select a number between 1 and 99 and press “ENTER”.
If you are interested in purchasing a CIS system for your kiln, contact Skutt or your local distributor.
