1 Introduction to the Controller and Manual
1.1 Description
The model 3216 controller/indicator is made by Eurotherm, and is fitted by Carbolite Gero
configured for immediate use as an indicator. It is configured for the input (thermocouple)
type for which it was ordered.
The indicator does not contain a real-time calendar, and is not subject to century-end date
problems.
When the indicator is supplied fitted into a furnace or oven then it is usually on whenever the
Instrument Switch is on. When it is supplied in a separate box, then it is on whenever the box
is connected to the electrical supply.
The indicator will only show the correct temperature if it is also connected to type of
thermocouple for which it is configured.

When pressed simultaneously the ACK function is used
to:
Return to the Home Menu.
Acknowledge an alarm if activated.
Reset a program after the program has ended
Arrow Keys

The arrow keys are used individually to adjust the
selected parameters and in combination to run a program
Note: 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
2.3 Operation
No operator action is normally required.
When switched on, the indicator lights up, goes through a short test routine, and then
displays the measured temperature
The output lights are not used, and the lower (setpoint) display is disabled.

3 User levels
3.1 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 Error! Reference source not found.)
If an incorrect code is entered the display reverts back to Level 1 home display (See Section
Error! Reference source not found.)
When level 2 operations have been completed, the supervisor must return to Level 1 either
manually or by ‘power cycling’, there is no time out function.
To Return to Level 1
1. Press and hold the page Key 
2. Press Down to select LEu 1
It is not necessary to enter a code when going from a higher level to a lower level
When level 1 is selected, the display reverts to the home display (See Section 2.1)

parameters which would be at the end of a scroll list, press and hold Scroll and use Up 
to return to a previous parameter.

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 3.1
4.1 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 until the display shows ID <customer ID>. Using the Up Down enter
your own identification number. This can range from 1-9999.
4.2 Units
Press scroll until the display shows units <Display Units>. Using the Up or Down
select the required units.

5 Digital Communications
5.1 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.

5.2 Digital Communications –RS485
If an RS485 option is supplied, then the furnace is fitted with two sub-miniature D-sockets.
Connection between products is by “straight” cable as follows:
RS485 cable:

female 9-pin (25-pin)
9-pin (25-pin) female

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 5.1.
5.3 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 until
the ADDR (ADDRESS) parameter is displayed. Use the Up Down to select the address
value.
