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.

Quick Start Guide

MC18-GB – v1.04

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  or Down  to 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 Up or Down  to choose LEu 2 (level 2)

5. Press the Up  or Down  to 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)
