3216
PID Temperature Controller
Installation and Basic Operation
1.
WHAT INSTRUMENT DO I HAVE?
Thank you for choosing the 3216 Temperature Controller.
This User Guide takes you through step by step instructions to help you to install,
wire, configure and use the controller. For features not covered in this User
Guide, a detailed Engineering Manual, Part No HA027986, and other related
handbooks can be downloaded from www.eurotherm.co.uk
Depending on how it was ordered, the controller may need to be configured when
it is first switched on.
The ordering code is shown on a label fixed to the side of the controller. The
hardware installed and the way in which it has been configured may be checked
against the ordering code at the bottom of this page.

Step 1: Installation
This instrument is intended for permanent installation, for indoor use only, and
enclosed in an electrical panel
Select a location which is subject to minimum vibrations and the ambient
temperature is within 0 and 55
The instrument can be mounted on a panel up to 15mm thick
To ensure IP65 and NEMA 4 front protection, mount on a non-textured surface.
Please read the safety information in section 4 before proceeding and refer to the
EMC Booklet part number HA025464 for further installation information.
1.2.1.
Panel Mounting the Controller
1.
Prepare a square cut-out in the mounting panel to the size shown
2.
Fit the IP65 sealing gasket, if required, behind
the front bezel of the controller
3.
Insert the controller through the cut-out
4.
Spring the panel retaining clips into place.
Secure the controller in position by holding it
level and pushing both retaining clips forward.
5.
Peel off the protective cover from the display

To Remove the Controller from its Sleeve
The controller can be unplugged from its sleeve by easing the latching ears
outwards and pulling it forward out of the sleeve. When plugging it back into its
sleeve, ensure that the latching ears click back into place to maintain the IP65
sealing.

Questions and answers
We have been using an Eurotherm 3216 temperature PID controller for our lab oven. Couple of days back suddenly it stopped working. We checked the thermocouple and heating coil and found okay. Please look at the attached pic where at the left-top corner "OP1" is not appearing. Do you have any idea about the fault?
If the "OP1" indicator is not appearing on the Eurotherm 3216 temperature PID controller, possible faults could include:
1. Output Not Activated – The controller may not be in a state that requires heating (OP1 typically indicates heating).
2. Incorrect Configuration – The controller settings may not be correctly configured for the intended operation.
3. Sensor Issues – A faulty or disconnected thermocouple could prevent the controller from detecting temperature changes.
4. Fault Code Present – The controller may be displaying a fault code that needs to be diagnosed using the fault code diagnostic table.
5. Wiring Problems – Loose or incorrect wiring connections could prevent OP1 from functioning.
6. Manual Mode – If the controller is set to manual mode, the output might not activate automatically.
7. Control Mode – The controller might not be in temperature control mode, affecting output activation.
Checking these factors and referring to the fault code diagnostic table in the manual can help identify and resolve the issue.
