Temperature and Process Indicator and Alarm Units

Installing and Operating Instructions

Thank you for choosing the 2132i or 2116i indicator and
alarm unit. It will provide accurate measurement and display
of temperature and other process variables with up to two
alarm outputs for operator alert and process protection.

Models 2132i/AL and 2116i/AL are Indicating alarm units
which come with an alarm relay output and logic I/O fitted.

Models 2132i/ND and 2116i/ND are Indicator only units
which come without the alarm relay output or logic I/O fitted.
Alarms can still be configured and flashed as messages in the
main display but they will not be able to operate a physical
output.

The indicator is supplied configured according to the ordering
code given on page 5. Check the coding on the side labels to
determine the configuration of your particular indicator.

DIMENSIONS AND INSTALLATION

To Install the Indicator

Please read the safety information on pages 5 & 6 before
proceeding.

OPERATION

Switch on the indicator. Following a 3 second self-test
sequence, you will see the display shown below. It is called
the HOME display.

ALARM INDICATION

The indicator has three internal ‘soft’ alarm setpoints which
can be attached to either the logic or relay outputs.

OP1

will flash when an alarm attached to the logic output
becomes true. (This is normally alarm 1). It will go steady
when the alarm is acknowledged but still true.

OP2

will flash when an alarm attached to the relay output
becomes true. (This is normally alarm 2 or 3). It will go
steady when the alarm is acknowledged but still true.

TO ACKNOWLEDGE A NEW ALARM

Press and together. This will also reset any latched
alarms that are no longer true.

In addition to the OP beacons, alarm messages are flashed in
the main display. The tables below list all of the possible

local wiring regulations. For example in the UK use the
latest version of the IEE wiring regulations, (BS7671). In
the USA use NEC Class 1 wiring methods.

Power Isolation

The installation must include a power isolating switch or
circuit breaker. This device should be in close proximity
to the indicator, within easy reach of the operator and
marked as the disconnecting device for the instrument.

Overcurrent protection

The power supply to the system should be fused
appropriately to protect the cabling to the units.

Voltage rating

The maximum continuous voltage applied between any of
the following terminals must not exceed 240Vac:

• relay output to logic, dc or sensor connections;

• any connection to ground.

The indicator must not be wired to a three phase supply
with an unearthed star connection. Under fault conditions
such a supply could rise above 240Vac with respect to
ground and the product would not be safe.

Conductive pollution

Electrically conductive pollution must be excluded from
the cabinet in which the indicator is mounted. For
example, carbon dust is a form of electrically conductive
pollution. To secure a suitable atmosphere in conditions
of conductive pollution, fit an air filter to the air intake of
the cabinet. Where condensation is likely, for example at
low temperatures, include a thermostatically controlled
heater in the cabinet.
This product has been designed to conform to BSEN61010
installation category II, pollution degree 2. These are defined
as follows:-

Installation Category II (CAT II)

For equipment on nominal 230V supply, the maximum rated
impulse voltage is 2500V.

Pollution Degree 2

Normally only non conductive pollution occurs.
Occasionally, however, a temporary conductivity caused by
condensation shall be expected.

Grounding of the temperature sensor
shield

In some installations it is common practice to replace the
temperature sensor while the indicator is still powered up.
Under these conditions, as additional protection against
electric shock, we recommend that the shield of the
temperature sensor is grounded. Do not rely on grounding
through the framework of the machine.

Over-temperature protection

When designing any control system it is essential to
consider what will happen if any part of the system should
fail. In temperature control applications the primary
danger is that the heating will remain constantly on. Apart
from spoiling the product, this could damage any process
machinery being controlled, or even cause a fire.
Reasons why the heating might remain constantly on
include:

• the temperature sensor becoming detached from the

process

• thermocouple wiring becoming short circuit;

• the controller failing with its heating output

constantly on

• an external valve or contactor sticking in the heating

condition

• the controller setpoint set too high.

Where damage or injury is possible, we recommend fitting
a separate over-temperature protection unit, with an
independent temperature sensor, which will isolate the
heating circuit.
This indicator can be used in addition to a controller as an
over temperature device. It is recommended that the relay
used to indicate the alarm condition should be set to high
alarm configured with sensor break and inverse ‘Inv’
operation so that it relaxes to the alarm condition when
power is removed.

Installation requirements for EMC

To ensure compliance with the European EMC directive
certain installation precautions are necessary as follows:

• For general guidance refer to Eurotherm Controls

EMC Installation Guide, HA025464.

• When using relay outputs it may be necessary to fit a

filter suitable for suppressing the emissions. The
filter requirements will depend on the type of load.
For typical applications we recommend Schaffner
FN321 or FN612.

• If the unit is used in table top equipment which is

plugged into a standard power socket, then it is
likely that compliance to the commercial and light
industrial emissions standard is required. In this
case to meet the conducted emissions requirement, a
suitable mains filter should be installed. We
recommend Schaffner types FN321 and FN612.

Routing of wires

To minimise the pick-up of electrical noise, the low
voltage DC connections and the sensor input wiring
should be routed away from high-current power cables.
Where it is impractical to do this, use shielded cables with
the shield grounded at both ends. In general keep cable
lengths to a minimum.
