1 Introduction to the Controller and Manual
1.1 Using This Manual
This manual aims to explain how to set up and operate the Eurotherm 3216 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:
1.1.1 3216P1 - Controller/Programmer
The 3216P1 is a digital temperature controller which uses PID algorithms to give excellent
temperature control. This controller can store and run a single program of 8 ramp/dwell
segments. The 3216P1 can also be used as a simple temperature controller.
1.1.2 3216P5 - Controller/Programmer
The 3216P5 is a digital temperature controller which uses PID algorithms to give excellent
temperature control. This controller can store up to 5 programs of 8 ramp/dwell segments.
The 3216P5 can also be used as a simple temperature controller.
1.2 PID Control
The 3216 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 to hold the furnace or oven at the desired
temperature.

3 Quick Start Guide
3.1 Operation as a simple controller
When switched on, the controller goes through a short test routine and then shows the
measured temperature (PV = Process Value) in the upper part of the display, and below it,
the set temperature (Set Point).
3.2 Changing the Set Point
Press Up Sor Down Tto select the required SP. If the SP is higher than the measured
temperature, the OP1 indicator will illuminate in the top left corner 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 then maintain it.
3.3 Using The controller
The parameters in the controller are first shown by a short code (mnemonic). After 5
Seconds a description of the parameter will scroll once along the display and then revert
back to the mnemonic. The scrolling text can be interrupted at any time by a single press of
any of the buttons, but will not scroll again until the parameter is returned to. In this manual
the mnemonic will be shown first, followed by the scrolling text in brackets;
e.g. Prog <program number>
3.4 Understanding User Levels
There are two user levels in the controller; Level 1(Operator) and Level 2 (Supervisor).
Level 1 (Operator) is for the day to day operation of the controller. These parameters are
not protected by a security code.
Level 2 (Supervisor) provides access to additional parameters. Access to these is protected
by a security code
To Enter Level 2
1. Press and hold the page key for 3 seconds.
2. The display will show Leu 1 GOTO
3. Release the page Key
4. Press the UpSor Down Tto choose LEu 2 (level 2)
5. Press the Up Sor Down Tto enter the code (Level 2 Code = 9).
If the correct code is entered, PASS should momentarily be displayed and then revert to the
level 2 home display (See Section 5.3)
If an incorrect code is entered the display reverts back to Level 1 home display (See Section
5.3)

Quick Start Guide

4 Setting up the controller
Before using the controller (or during its lifetime) certain parameters may have to be set,
depending on specific requirements. To do this the controller must be set to supervisor level
(Level 2) see section 3.4
4.1 Maximum Output Power Setting
Press scroll 3until the display shows OP.HI <Output High>. Using Up Sand Down T
select the output power required as a percentage.
Depending on the furnace or oven model, the maximum output power setting OPHi may be
accessible or locked.
For Silicon Carbide heated furnaces, the parameter is accessible to allow compensation for
element ageing. Refer to the product manual for details.
In many models the maximum output power setting depends on the supply voltage, refer to
the product manual for details.
4.2 Customer ID.
A furnace or oven identification number can be entered if required. This maybe used to
identify one of many units, for production or quality control systems.
Press scroll 3until the display shows ID <customer ID>. Using the Up SDown Tenter
your own identification number. This can range from 1-9999.
4.3 Units
Press scroll 3until the display shows units <Display Units>. Using the Up Sor Down
Tselect the required units.

4.4 Language
The scrolling text on the 3216 can be shown in different languages, this can only be set at
the factory and therefore must be specified at the time of placing an order.
4.5 Scrolling Text
If at any time the scrolling text is not required.
Press and hold the Page for three seconds until “GOTO” is displayed

Programming

MC18-GB – v1.04
Press Scroll 3until the display shows. TEXT <ENABLE/DISABLE SCROLLING TEXT>
Use the Up SDown Tto select ON or OFF
4.6 Customer Calibration
The 3216 series of controllers are calibrated for life at manufacture, there may however be
sensor or other system errors, which affect the accuracy of the measured temperature.
Customer calibration can be used to compensate for these errors.
Dual Offset
Dual point calibration uses two offset values at two corresponding temperatures; this
changes the calibration linearly as the temperature increases or decreases.
Press scroll 3until the display shows CAL.P (Enter Calibration Code) Use Up SDown
Tto enter the password code. (Calibration Pass Code = 95). When the correct password
has been entered the display will show PNT.LO. If the wrong pass code is entered the display
will revert to zero pass code, until the correct pass code is entered.
When the correct pass code is entered and PNT.LO (Adjust Low Point) is displayed. Use
Up SDown Tto enter the Low Temperature Point, which you want to apply an Offset.
Press scroll 3until the display shows OFS.LO (Adjust Low OFFset). Use Up SDown Tto
enter the amount Offset you want to apply to the Low Temperature Point.
Press scroll 3until the display shows PNT.HI (Adjust High Point). Use Up SDown T
to enter the High Temperature Point, which you want to apply an Offset.
Press scroll 3until the display shows OFS.HI (Adjust High OFFset). Use the Up SDown
Tto enter the amount Offset you want to apply the High Temperature Point.
Once the calibration details have been entered, press scroll 3until the display shows the
next required parameter or return to the home list. The calibration data will now be protected
by the pass code. To edit the data the above procedure must be followed.

Programming
10 MC18-GB – v1.04
Single Offset
If a constant offset is required across the temperature range, set the required “High Point”
(PNT.HI) and “Low Point” (PNT.LO) to the required values (not the same), then set the “low
Offset” (OFS.LO) and “High Offset” (OFS.HI) to the same value.
Caution! - Do not make PNT.LO and PNT.HI the same value as the controller will
not work correctly and could cause your furnace or oven to overheat.
4.7 Holdback
If the temperature ramp rate of the program is quicker than the furnace or oven can achieve,
the program will wait until the temperature of the furnace or oven catches up.
e.g. If a Holdback value of 10 is set and the program is set to ramp to a setpoint of 600°C,
the program will reach 600°C, then go into an hold state; the hold indicator will light until the
furnace or oven temperature reaches 590°C, the program will then continue to control
again.
The hold back will only apply once per Segment, therefore when control has been re-
established, the hold back will not apply again to that segment, even if the furnace or oven
temperature go outside the hold back band.
Holdback can only be accessed in supervisor level (level 2) by scrolling with the Scroll 3
until the display shows H.BACK <PROGRAM HOLD BACK>: Use the Up SDown Tto select the
required Hold Back value.
If a multi programmer is used, each program can have its own Holdback value assigned to
it.
Note: When a Holdback is set, each segment used must have a Ramp Rate assigned
to it, in order for it to be recognised by the program.
5 Programming
5.1 Creating a Program
Programs can be created in level 1 or level 2 of the 3216 P1 and 3216P5. Each program
contains 8 Ramp/Dwell pairs.
Note:
A currently active program cannot be altered. Go into reset mode before starting to create or
modify a program

Ramp Units
Press scroll 3until the display shows RAMP.U <Ramp Units>: Use the Up SDown Tto
select the Ramp Units of Hour, Min or Seconds.
Dwell Units
Press Scroll 3until the display shows DWEL.U <Dwell Units>: Use the Up SDown Tto
select the Dwell Units of Hour or Min.
Holdback (See section 4.7)
Press Scroll 3until the display shows H.BACK <Program Hold Back>: If a Holdback value is
required, use the Up SDown Tto enter the required value or select “OFF” if no holdback is
required.
Ramp Rate
Press Scroll 3until the display shows RMP.1 <Ramp Rate 1>: Using the Up SDown T
enter the value for the first ramp rate depending on the Ramp Units selected. If the Ramp
segment is not required select “OFF”.
Target Setpoint
Press Scroll 3until the display shows T.SP 1 <Target SP 1>: Enter the temperature that
you want the unit to ramp up to using “Ramp rate 1”.
If “Ramp Rate 1” has been set to “OFF”. The unit will Heat/Cool directly to the Target SP.
Dwell Time
Press Scroll 3until the display shows DWELl. 1 <DWELL TIME 1>: Enter the time to dwell
at “Target SP 1”. If the dwell segment is not required, use the Down Tto select OFF, which
is below the Zero value.
This Process is repeated for each of the 8 segments of the program.
If not all the segments are used for a program, the Ramp & Dwell of each of the subsequent
Segments should be set to OFF.
A program will end in one of two ways, either revert to the control Set Point or dwell at the
temperature set in the last segment used. When a program finishes on a dwell and the dwell
time expires the temperature will revert to the control setpoint.
Note: Before running a program ensure that the control set point is set to Zero to avoid
unexpected heating at the end of the program.

5.3 Program Status
While the program is running in level 1 or level 2, the Home Display shows two values at
any one time:
Process Value
The upper display shows the measured temperature of the furnace (PV).
PSP, Segment Type and Number
The lower display continually alternates between the programs current set value (Program
SP = PSP) and scrolling text, indicating the current status of the program whether RAMP or
DWELLING followed by the segment number.
Additional information can be obtained using the scroll 3key while the program is running.
Working Output Power
From the home display, press Scroll 3until the display shows WRK.OP <WORKING OUTPUT

MC18-GB – v1.04
Time Remaining
Press scroll 3until the display shows T.REMN <TIME REMAINING>. This shows the dwell
time remaining for the current segment. There is no value for “Ramp Time Remaining”
therefore when the program is ramping the dwell time set will be shown and will only begin
to count down when the ramp has finished.
Program Review
Further presses of scroll 3will reveal the settings of the current program running. These
parameters are locked, while the program is running.
Program Hold with Holdback
If a holdback value has been set (see Programming section 4.7) and the program goes into
a hold state, the red “HLD” indicator will light, until the “PV” catches up.
If while in this condition the program itself is put into “Hold” by pressing the Up S, Down T
together, the “HLD” indicator will turn off and the “Run” indicator will flash, indicating the
program is on hold. When the program is started again by pressing the up S, down T
together, the “Run “ indicator will stop flashing and show continually and the “HLD” indicator
will light, if the “PV” has not caught up with the program.
Power Failure
If there is a power failure while the program is running and the power is subsequently
restored, the scrolling text will read <POWER FAIL - PROGRAM RESET>.
To acknowledge this message and to reset the program Press “ACK” function
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 scrolling message on
the display and a flashing red ALM (Alarm) indicator. The alarm may also switch an output –
usually a relay to allow external devices to be operated when an alarm occurs. Alarms only
operate if they have been configured and are dependant 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 2.2) before it is
reset.
If an alarm has been activated the red “ALM” indicator will light and the scrolling text will
indicate the type of alarm.
To Acknowledge an alarm and cancel the “ALM” indicator, press ACK function.
Note:
The alarm indicator may seem to be permanently on when viewed from above. When an
alarm is active the indicator should only be flashing, to confirm this, the controller must be
viewed directly from the front.

6 Options
Because options can be ordered in a variety of combinations and for a variety of purposes,
exact instructions are not given here. The full Eurotherm manual may be required to
determine customer parameter settings. To reveal or hide parameters in the controller it is
necessary to go into configuration modes and enter a security codes. Please consult
Carbolite.
6.1 Digital Communications – RS232
If the RS232 option is supplied, then the furnace is fitted with one subminiature D-socket
connected to the controller communications (comms) module. RS232 is suitable for direct
connection to a personal computer (PC), using a “straight through” cable as follows (the
linked pins at the computer end are recommended but may not be necessary). The cable is
usually 9-pin at the furnace end and 9-pin at the computer, but other alternatives are shown
in parentheses.

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.

Options
16 MC18-GB – v1.04
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 scroll key 3until
the ADDR (ADDRESS) parameter is displayed. Use the Up SDown Tto select the address
value.
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 guard against the connection of a mains supply to the
panel plug.
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 Insulated terminal
sockets on the control panel.
Controller configuration depends on customer requirements.
Remote input (when specified) may be switched on and off using the Alternative Setpoint
Enable parameter in the controller home list, if this was made available for a particular
application. Remote output does not require switching on and off.
