1. Installation and Basic Operation
1.1 What Instrument Do I Have?
Thank you for choosing this 3200 series Temperature
Controller/Programmer.
The 3200 series provide precise temperature control of
industrial processes and is available in three standard DIN
sizes:-
• 1/16 DIN Model Number 3216
• 1/8 DIN Model Number 3208
• 1/4 DIN Model Number 3204
A universal input accepts various thermocouples, RTDs or
process inputs. Up to three (3216) or four (3208 and 3204)
outputs can be configured for control, alarm or re-
transmission purposes. Digital communications and a current
transformer input are available as options.
The controller may have been ordered to a hardware code
only or pre-configured using an optional ‘Quick Start’ code.
The label fitted to the side of the sleeve shows the ordering
code that the controller was supplied to. The last two sets of
five digits show the Quick Code. If the Quick Code shows
*****/***** the controller will need to be configured when it
is first switched on.
This Manual takes you through all aspects of installation,
wiring, configuration and use of the controller.
1.2 Unpacking Your Controller
The controller is supplied with:-
• Sleeve (with the controller fitted in the sleeve)
• Two panel retaining clips and IP65 sealing gasket
mounted on the sleeve
• Component packet containing a snubber for each relay
output (see section 2.9) and a 2.49Ωresistor for current
inputs (see section 2.5)
• User Guide

1.4 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 the
ambient temperature is within 0 and 55oC (32 - 131oF) and
humidity 5 to 95% RH non condensing.
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 2.16 before
proceeding. The EMC Booklet part number HA025464
gives further installation information.
1.4.1 Panel Mounting the Controller
1. Prepare a cut-out in the mounting panel to the size
shown. If a number of controllers are to be mounted in
the same panel observe the minimum spacing shown.
2. Fit the IP65 sealing gasket 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.
1.4.2 Panel Cut Out Sizes
1.4.3 Recommended minimum spacing of
controllers
Applies to all models.
1.4.4 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

2.4 Wire Sizes
The screw terminals accept wire sizes from 0.5 to 1.5 mm (16
to 22AWG). Hinged covers prevent hands or metal making
accidental contact with live wires. The rear terminal screws
should be tightened to 0.4Nm (3.5lb in).
2.5 Sensor Input (Measuring Input)
• Do not run input wires together with power cables
• When shielded cable is used, it should be grounded at
one point only
• Any external components (such as zener barriers, etc)
connected between sensor and input terminals may cause
errors in measurement due to excessive and/or un-
balanced line resistance or possible leakage currents
• Not isolated from the logic outputs & digital inputs
Thermocouple Input
Positive
Negative
• Use the correct compensating cable preferably shielded
RTD Input
PRT
PRT
Lead compensation
• The resistance of the three wires must be the same. The
line resistance may cause errors if it is greater than 22Ω
Linear Input (mA or V)
Positive
Negative
• For a mA input connect the 2.49Ωburden resistor
supplied between the V+ and V- terminals as shown
• For a 0-10Vdc input an external input adapter is
required (not supplied). Part number: SUB21/IV10
2.6 Input/Output 1 & Output 2
These outputs can be logic (SSR drive), or relay, or mA dc.
In addition the logic output 1 can be used as a contact closure
input.
Relay Output (Form A, normally open)
• Isolated output 240Vac CAT II
• Contact rating: 2A 264Vac resistive
• Output functions: Heating, or cooling, or alarm or
motorised valve open or closed
Logic (SSR drive) Output

• Output ON state: 12Vdc at 40mA max
• Output OFF state: <100mV, <100µA
• Output functions: Heating, or cooling, or alarm or
motorised valve open or closed
• The output switching rate must be set to prevent
damage to the output device in use. See parameter
1.PLS or 2.PLS in section 4.2.
DC Output
The DC output is not available in 3116.
• Not isolated from the sensor input
• Software configurable: 0-20mA or 4-20mA.
• Max load resistance: 500Ω
• Calibration accuracy: 1%, +100µA
• Output functions: Heating, or cooling, or retransmission.
Logic Contact Closure Input (I/O 1 only)
• Not isolated from the sensor input

• Contact open > 500Ω. Contact closed < 200Ω
• Input functions: Please refer to the list in the Quick Start
codes.
