Introduction to the Controller and Manual
1.1 Using This Manual
This manual aims to explain how to set up and operate the Eurotherm 3508 series of
controllers; it must be read in conjunction with the product main manual.
Due to the complex nature of furnace or oven 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:
3508 P1 –Controller/Programmer
The 3508 P1 is a digital temperature controller which uses PID algorithms to give excellent
temperature control when properly set. This controller can store and run a single program of
up to 20 segments. The 3508P1 can also be used as a simple temperature controller.
3508P10 –Controller/Programmer
The 3508 P10 is a digital temperature controller which uses PID algorithms to give excellent
temperature control when properly set. This controller can store 10 programs of up to 50
segments each. Programs can be run individually or linked by a Call parameter as sub-
programs or to form single long programs. The 3508P10 can also be used as a simple
temperature controller.
3508P25 –Controller/Programmer
The 3508 P25 is a digital temperature controller which uses PID algorithms to give excellent
temperature control when properly set. This controller has a maximum of 500 segments or
25 programs; each program has a maximum of 50 segments. For example a 3508P25 could
store 10 programs with 50 segments or 25 programs with 20 segments. Programs can be
run individually or linked by a Call parameter as sub-programs or to form single long
programs. The 3508P25 can also be used as a simple temperature controller.
The 3508 does not contain a real-time calendar.
1.2 PID Control
The 3508 series of controllers 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 hold the furnace or oven at the desired temperature.

3.1 Operation as a simple controller
When switched on the controller goes through a short test routine and then shows the
measured temperature. Below it is shown the setpoint temperature (SP) and percentage of
power output.
3.2 Changing the Setpoint
Press up down to select the required SP. If the SP is higher than the measured
temperature, the OP1 indicator will illuminate at the top of the display, indicating that the
controller is calling for power (giving an output).
The controller will immediately attempt to reach the set temperature and maintain it.
3.3 Resetting the programmer
To reset the programmer to simple controller mode, press RUN/HOLD for 2 seconds.
3.4 Operating the current program
To avoid unwanted heating at the end of a program, set the SP temperature to zero
before running a program.
Ensure the programmer is reset to simple controller mode before starting a program,
by pressing RUN/HOLD for 2 seconds.
To start the program, press RUN/HOLD twice, RUN will light up on the display.
The displayed Program Setpoint (PSP) follows ramps, dwells and steps as the program
runs. The SP temperature of the controller does not apply when a program is running.
To pause the program, press RUN/HOLD.
To stop the program and return to simple controlling (reset), press RUN/HOLD for 2
seconds.
When the program ends, the programmer will either:
Automatically reset to operation as a simple controller.
Dwell at the last temperature of the program (with the RUN indicator flashing), until
the operator presses RUN/HOLD for 2 seconds to manually reset, or presses
RUN/HOLD once to restart the program.
Turn power to the elements down to zero.
3.5 Understanding User Levels
There are two levels in the controller; Level 1(Operator) and Level 2 (Supervisor).
Level 1 (Operator) is for the day-to-day operation of the controller and parameters are not
protected by a security code. There are 3 pages at this level. Page 1, Customer Identity,
can only be altered in level 2. Page 2 shows the current program status. Page 3 is for
writing and viewing programs.
Level 2 (Supervisor) provides access to additional parameters and access to these is
protected by a security code. A further 4 pages are accessible in this level as follows;
Customer identity, Control Output Hi percentage, Units.
To Enter Level 2:
1. Press and hold page for 3 seconds. The display will show “Access Goto Level 1”

2. Press up to select level 2. After a short pause the display will show “Access Pass
code”.
3. Press up or down to enter the pass code 9, Pass is momentarily displayed. After
a short pause the display will return to home, the controller is now in level 2.
When Level 2 operations have been completed the supervisor must return to Level 1
manually. It is not necessary to enter a code when going from a higher level to a lower level.
To Return to Level 1:
1. Press and hold page for 3 seconds. The display will show “Access Goto Level 2.
2. Press down to go to level 1. After a short pause the display will revert to home, the
controller is now in level 1.

5.1 Programming Notes
Programs can be created in Level 1 or Level 2 of the 3508.
For the P10 and P25, new programs can be created while the current program is running.
To avoid unwanted heating at the end of a program, set the controller SP temperature to
zero before running a program.
All new unused programs show only 1 segment of type End.
The minimum number of segments for a program is 2. The second being an End type.
Ramp-to-setpoint control. To achieve this, create a two segment program. Set the first
segment type as Rate or Time. Set the second segment type End type Dwell.
For the P10 and P25, programs can be linked together using a “Call” segment. However a
lower number program can not be called and a program can not be ended with a call
segment.
A program can be ended in four ways:
1. With End segment set to S.OP the power to the elements is turned down to 0%, no
matter what the Setpoint temperature is.
2. With End segment set to Reset and the Setpoint temperature turned down to zero,
power to the elements will be 0%. To do this set the Setpoint temperature to the
minimum possible. For type B thermocouples this will be bellow zero.
3. With the End segment set to Reset. The controller will try to reach and maintain the
Setpoint temperature.
4. With the End segment set to Dwell. The controller will dwell at the PSP of the last
segment (RUN indicator flashes), until it is reset.
To reduce the number of segments in a program, change the last required segment to an
End type. You will be asked to press to cancel or for OK.
To cancel all segments in a program, change the first segment to an End type.
To alter parameters or segments of a running program, this program must be held or reset.
Press RUN/HOLD to pause the program, or press RUN/HOLD for 2 seconds to reset.
5.2 Holdback
Holdback can be used to prevent the program from running ahead of the actual heating or
cooling.
The Holdback value is the amount, in degrees, by which the Program Setpoint can run
ahead of the measured temperature before Holdback operates. The value applies to a
whole program.
To set the value press page twice, press scroll until Holdback Value appears and press
up or down to set.
Holdback can be used in Rate, Time and Step segments.

Programming
10
MC19-1.22
For Rate and Time segments Holdback will operate during the segment.
For a Step segment Holdback delays continuation to the next segment until the step
target is reached.
The Holdback Type can be set as follows:
Low Applies to heating only
High Applies to cooling only
Band Applies to both heating and cooling
Off Holdback is off
To set the Holdback type press page twice, then press scroll until the display shows
Holdback Type for each segment and press up or down to set.
The default setting for Holdback is Off.
5.3 Wait Segments
Wait prevents the program proceeding to the next segment, in a similar way to Holdback,
until the selected ‘Wait-For’ parameter has been met. There are 5 ‘Wait For’ parameters.
The first 4 only work if there are configured inputs to the controller.
1 PrgIn1 Wait until Input 1 is true
2 PrgIn2 Wait until Input 2 is true
3 PrgIn 1&2 Wait until Inputs 1 AND 2 are true
4 PrgIn 1or2 Wait until Inputs 1 OR 2 is true
5 PVWaitIP Wait until the measured temperature reaches a threshold value before
continuing. It can operate in one of 4 ways:
5.1 ‘Abs Hi’ Wait until the measured temperature is greater than or equal to a
value ‘WaitVal’ set for that segment.
5.2 ’Abs Lo’ Wait until the measured temperature is less than or equal to a value
‘WaitVal’ set for that segment.
5.3 ‘Dev Hi’ Wait until the measured temperature exceeds a fixed* threshold by
an amount ‘WaitVal’ set for that segment.
5.4 ‘Dev Lo’ Wait until the measured temperature drops below a fixed* threshold
by an amount ‘WaitVal’ set for that segment.
* The fixed threshold used by deviation parameters is set in the configuration level of the
programmer and if required should be requested when purchasing a furnace from Carbolite
Gero.
5.4 Program Cycling
The Cycles parameter sets the number of times the program will run.
The default setting is 1 cycle.

state, the green HLD indicator will flash, until the measured temperature catches up.
If while in this condition the program itself is put into hold by pressing the RUN/HLD button,
the “HLD” indicator will stop flashing and remain on with the “RUN” indicator. When the
program is started again by pressing the “RUN/HLD” button, the “HLD” indicator will flash
again if the measured temperature has not caught up with the program.
Programming note:
For P10 and P25 models you can create or change other programs while the current
program is running, go to operator Page 3.
5.11 Power Failure Recovery
If there is a power interruption to the controller during a program, when power is restored
the controller pauses the program, then ramps the temperature back up to the current
Program Setpoint (PSP) before continuing the program.
Power fail during ramp segments: The ramp rate will be that of the current ramp
segment.
Power fail during Dwell segments: The ramp rate will be that of the previous ramp
segment. If a previous ramp segment does not exist, then the dwell will continue at
the current measured temperature.

Programming
14
MC19-1.22
Power fail during Time-to-target segments: The ramp rate will be that of the current
segment. The ramp rate is maintained, but the time remaining is recalculated.
If there is a power interruption while controlling to Setpoint, when power is restored the
controller automatically calls for maximum power.
5.12 Alarms
Alarms are used to alert the operator when a pre-set level has been exceeded or a function
error has occurred such as a sensor break. They are indicated by a flashing red ALM
(Alarm) indicator. The alarm may also switch an output –usually a relay to allow external
devices to operate when an alarm occurs. Alarms only operate if they have been configured
and are dependent on customer requirements.
How to acknowledge an alarm will depend on the type of latching which has been
configured. A non-latched alarm will reset itself when the alarm condition is removed. A
latched alarm requires acknowledgement with the “ACK” function (section 2.1) before it is
reset.
If an alarm has been activated the red “ALM” indicator will flash and the text will indicate the
type of alarm.
To acknowledge an alarm and cancel the “ALM” indicator, press and together.

RS485 cable: furnace to

If a boxed KD485 RS485 to RS232 converter is supplied, then the connection cable from
furnace to KD485 should be a “straight” cable, the same as the furnace-to-furnace cable.
The connection between the KD485 and the PC should be a “crossover” cable, the same as
the Furnace to PC cable in section 6.1.
6.3 Comms Address
Typically the comms address is set to 1, but this can be changed. In the case of RS485 and
multiple instruments it is necessary to set different addresses.

To change the address value access the level 2 list. In level 2 press the page key until the
COMMS parameter is displayed. Press up 
6.4 Alarm Option
When an alarm board is fitted with free contacts for customer use, the contacts are taken to
a panel plug on the control panel, wired as indicated:
The purpose of the 2 amp fuse is to protect the internal circuitry from excess electrical
current.
The instrument configuration, and parameters available to the operator, depend on the
customer requirements.
6.5 Remote Input and Output (Analogue Communications)
When analogue communications are fitted, the contacts are taken to “banana plug” sockets
on the control panel.
Controller configuration depends on customer requirements.
Remote input (when specified) may be switched on and off using the Remote setpoint
enable parameter in the controller level 2, if this was made available for a particular
application. In level 2 press page until ‘REM SP Enable’ is displayed, press up or down
to select SP1 (the normal controller setpoint) or SP2 (the remote input setpoint), ‘SPX’ will
appear in the top left corner of the display.
Remote output does not require switching on and off.
6.6 Program segment output
When the customer requirement is for program segment output, an extra parameter is
revealed in the PROG list. For each program segment, after the segment type and settings,
the parameter EVENT OUTS appears. This has values on and off. If the value is set to
on, then the relay closes during the segment and a small 1 appears in the top left of the
screen.
If more than one program segment output is fitted, then there are extra boxes depending on
how many event outputs there are.
