At Switch ON
The initial display when you switch ON gives useful information about your controller.
The display is in the form X N
1
.N
2
.N
3
where X is a letter and N are numbers.
X is the thermocouple type r, S, n, or k
N
1
.N
2
is the software version (It should be quoted if you contact us with a technical query)
N
3
is the model type of your controller;-
1 = Single Program. (ST3SP)
2 = Multi Program. (ST3MP)
3 = Multi Program with linking. (ST3MPL)
4 = MPL with optional event relay (ST3E)
5 = 3 Zone control. (ST3Z)
Program Entry
The ‘Quick Guide’ should be used as a first approach to entering programs. The following gives specific detail not covered
by the guide and assumes you are familiar with the general operation of the controller.
RAMPS
All ramps may be Up or Down.. The controller decides automatically which way to ramp depending upon the values you
enter into the program. When you start a program the start temperature for a ramp is the current kiln temperature.
To omit a ramp segment from a firing cycle, decrement the ramp rate below zero until ‘PASS’ is displayed. (You cannot
‘PASS’ Ramp 2 since this would also remove the subsequent Soak)
To jump immediately to the next segment, increment the ramp rate above 1000ºC/Hr until ‘FULL’ is displayed. During a
firing this will immediately load the ramp end setpoint and then wait until the kiln catches up before proceeding with the
next segment.
SOAK
You may Soak for up to 99 Hr 59 Min. Selecting zero for a soak time will give what is called a “Cut-Off” firing, where the
kiln rises to the desired soak temperature but does not hold at this temperature.
LINKING (Not applicable to SP and MP models)
At the point of the program entry where ‘End’ is displayed, you may link to another program if a more complex firing cycle
is required. Whilst ‘End’ is displayed in program entry press and hold the secret key under the ‘P’ of IPCO. The
↑
/
↓
keys
allow a Ln number to be displayed. When the program is run this link number will direct the controller to continue firing
with the values in the ‘linked’ program. You may make as many links as you wish, however, each link uses up one of your
ten programs which are thus not available to be run independently. Also be very careful that you do not link back to a
program which is earlier in your current firing cycle, or a continuous loop will result.
During The Firing
The display will normally show the temperature in the kiln.
The kiln LED is lit when power is being applied to the kiln.
The Slow LED (Flashing) is lit if the kiln is too slow to follow the program. Whilst a
program is running
(i.e.. One of the green LED’s will be lit) a number of other features are available;-
MONITORING FIRING PROGRESS
The
↓
key may be used to examine additional values held within the controller. What is displayed will depend upon the
position in the program and the model version. For the SP, MP and MPL versions the values shown are ;-
(Flashing ºC LED indicates ‘Monitoring’ operation)
RAMP;- Prog No, Current setpoint.
SOAK;-
Prog No, Current setpoint, Remaining soak time.
For the Three Zone unit the above value are followed by Zone 2, & Zone 3 current temperatures.
REVIEW PROGRAM
The
→
key will allow you to step through all the current program values and amend them as required. These amendments
will normally have immediate effect upon the firing.
JUMP TO NEXT SEGMENT
Pressing the È key will advance the program one segment.
If the next segment is a ramp the start temperature will be the actual temperature at which the button was pressed. The rate of
rise (or fall) and the end temperature are as defined in the program. If the next segment is a soak the controller will
immediately apply the soak temperature as the setpoint and wait for the kiln to catch up.

Viewing or Modifying a firing Cycle
N.B. These instructions assume that you are using the controller for the first time. If the controller has been used then values other
than those illustrated may be displayed.
