1 Introduction to the Controller and Manual
1.1 Using This Manual
This manual aims to explain how to set up and operate the Carbolite 302P controller; it must
be read in conjunction with the product main manual.
Due to the complex nature of furnace control the use of technical terms throughout this
manual is unavoidable. Explanations of these terms can be found in the ‘Glossary of Terms’
at the back of this manual.
This manual covers the operation of:
1.2 302P - Controller
The 302P is a digital temperature controller which uses PID algorithms to give excellent
temperature control when properly set. This controller can store 4 programs of 4 ramp/dwell
segments. Programs 1,2& 3 are protected by password and program 4 is open to edit.
1.3 PID Control
The 302P4 controller use PID (Proportional, Integral, Derivative) temperature control. This
type of control uses a complex mathematical control system to adjust the power being sent
to the elements and to hold the furnace or oven at the desired temperature.

2.2 Keys
Basic Operation
Note: In operator set up mode, if a parameter is selected and no further action is taken, the
display will time out and revert back to the home display in its working level after
approximately 1 minute.
3 Quick Start Guide
3.1 Home Display
When switched on, the controller goes through a short lamp test routine and then displays
the process value in the upper display and “rdy” in the lower display. This is known as the
“Home Display”.

Quick Start Guide
MC22 -GB-v1.01
3.2 Selecting a program
With basic operator mode selected OP.b (see section 3.6) press the function key once to
display nprG in the lower display and the program number in the upper display. Select the
required program number using the Down or Up After selection press the function key
to store the parameter.
3.3 Starting the program Cycle
To start the program the “Run” button must be pressed and held down for 1.5 seconds.
After 1.5 seconds the lower run indicator lamp will be lit continually and the displays will
show the program setpoint (PSP); lower display, process value (PV); upper display.
3.4 Program Cycle
Once the program has been started, the heat light (situated below the power switch) and the
upper power output indicator lamp will initially display a long pulse at a continuous cycle
rate, these display pulses will reduce within the same cycle rate, as the furnace approaches
the desired temperature or a program setpoint.
As the program is running the lower indicator lamp will be lit continuously.
When the program has finished its cycle the lower indicator lamp will be switched off and
the lower display will show End.
3.5 Program Hold and Cancel
To hold the program, the “Run” button must be pressed and held down for 1.5 seconds,
while the program is running. When the program is in hold, the lower display will flash
between the word “hoLd” and current Program set point and the lower indicator lamp will
flash continually.
To remove the hold status, the “Run” button must be pressed and held down for 1.5
seconds. After 1.5 seconds the lower display will no longer display hold and the lower
indicator lamp will be lit continually. The program will then continue from the current process
value indicated on the upper display.
To cancel a program, either while the progam is running or in the hold condition, the “Run”
button must be pressed and held down for 5 seconds. After 5 seconds the lower indicator
lamp will switch off, the lower display will show “rdy”, and the upper display will show the
current process value.
To restart the program refer to section 3.3
3.6 Understanding Operator Levels
There are three user levels in the controller; Op.b (Basic Operator Mode) OP.E (Enhanced
Mode) and OP.P (Program Edit Mode).
There are also three further engineering levels indicated by OPS, CP1 and CnF which are
factory set and not covered within this manual.

Quick Start Guide
MC22-GB-V1.00
Op.b (Basic Operator Mode) is for running the program only. No other parameters are
available.
OP.E (Enhanced Mode) is for calibration and address assignment. Access to these is
protected by security code =17.
OP.P (Program editing mode).provides access to programming parameters. Access to
these is protected by security code =4
To Enter OP.E (Enhanced mode) starting from Basic operator mode (OP.b).
1. From the home display press and hold the Function and Run keys
simultaneously for more than 3 seconds.
2. The display will show OPr lower display and OP.b upper display (Op.b being the
current active mode)
3. Press the Up or Down to choose OP.E
4. Press to enter selected level.
5. The word pass will be shown on the bottom display and ---- on the top display. This
will time out after 10 seconds, during this period the password should be selected
using the Up or Down
6. Press to enter the password.
7. When the correct password has been entered the upper display will flash PASS. If an
incorrect password is entered the upper display will flash Errand then return to the
home display.
Once in Enhanced mode, the parameters within this level can be accessed by pressing
page to descend the list, or run to ascend the list.
When OP.E operations have been completed, OP.b mode must be returned to manually as
outlined below.

Quick Start Guide
MC22 -GB-v1.01
To Enter OP.P (Program Editing Mode).
8. From the home display press and hold the Function and Run keys
simultaneously for more than 3 seconds.
9. The display will show OPr lower display and OP.b upper display (Op.b being the
current active mode)
10. Press the Up or Down to choose OP.P
11. Press to enter selected level.
12. The word pass will be shown on the bottom display and ---- on the top display. This
will time out after 10 seconds, during this period the password should be selected
using the Up or Down
13. Press to enter the password.
14. When the correct password has been entered the upper display will flash PASS. If an
incorrect password is entered the upper display will flash Err and then return to the
home display.
15. Once in the program edit mode the parameters within this mode can be accessed by
pressing page to descend the list, or run to ascend the list.
Note: There is no time out or power cycling function, whereby the instrument automatically
returns to a lower operating mode.
When OP.P operations have been completed, OP.b mode must be returned to manually as
outlined below.
To exit OP.E (Enhanced mode) or OP.P (Program Editing Mode) and return to OP.b (Basic
operator mode).
1. Return to the top level home display of the OP.E or OP.s list. This will be where the
displays show the, program setpoint (PSP) in the lower display and process value
(PV) in the upper display. This can be done either by leaving the current selected
parameter to time out after 10 seconds, or by pressing the page or Run to scroll
through the parameter list and return to the top level home display.
2. Press and hold Function and Run simultaneously for more than 3 seconds.
3. The display will show OPr lower display and OP.E or OP.P upper display (OP.E or
OP.P being the current active mode)
4. Press the Up or Down to choose OP.b
5. Press to enter selected level.
6. No password is required to enter a lower level of operation, therefore the display will
return to basic operator mode and show the, program setpoint (PSP); lower display
and process value (PV); upper display.
Check that no parameters are not available by pressing the page or run keys.
