* General Notes about Relays and Inductive Loads
High voltage transients may occur when switching
inductive loads such as some contact ors or solenoid
valves. Through the internal contact s , these transients
may introduce disturbances which could affect the
performance of the instrument.
For this type of load it is recommended that a ‘snubber’
be connected across the normally open contact of the
relay switching the load. The snub ber recommended
consists of a series connected resistor/capacitor
(typically 15nF/100Ω). A snubber will also prolong the
life of the relay contacts.
A snubber should also be connected acr oss the output
terminal of a triac output to prevent f alse triggering
under line transient conditions.
WARNING
When the relay contact is open, or it is connected
to a high impedance load, it passes a current
(typically 0.6mA at 110Vac and 1.2mA at 230Vac).
You must ensure that this current will not hold on
low power electrical loads. If the load is of this
type, the snubber should not be connected.

Directive 2006/95/EC, by the application of the safety
standard EN 61010.
Electromagnetic compatibility
This indicator conforms with the es s ential protection
requirements of the EMC Directive 2004/108/EC by the
application of a Technical Constr uction File. This
instrument satisfies the general requirements of the
industrial environment defined in EN 61326. For more
information on product compliance, refer to the
Technical Construction File.
GENERAL
The information contained in this manual is subject to
change without notice. While every effor t has been
made to ensure the accuracy of the information, your
supplier shall not be held liable f or errors contained
herein.
Unpacking and storage
The packaging should contain an inst rument mounted
in its sleeve, two mounting brackets for panel
installation and an Installation & Operating guide.
Certain ranges are supplied with an input adapter.
If on receipt, the packaging or the instrument is
damaged, do not install the product but c ontact your
supplier. If the instrument is to be stor ed before use,
protect from humidity and dust in an ambient
temperature range of -10OC to +70OC.
Service and repair
This indicator has no user serviceable parts. Contact
your supplier for repair.
Caution: Charged capacitors
Before removing an instrument f rom its sleeve,
disconnect the supply and wait at least two minutes to
allow capacitors to discharge. I t may be convenient to
partially withdraw the instrument from the sleeve, then
pause before completing the removal. In any case,
avoid touching the exposed elect r oni c s of an
instrument when withdrawing it from the sleeve.
Failure to observe these precautions m ay cause
damage to components of the instrume nt or some
discomfort to the user.
Electrostatic discharge precautions
When the indicator is removed from it s sleeve, some of
the exposed electronic components are vulnerable to
damage by electrostatic discharge from someone
handling the indicator. To avoid this, before handling
the unplugged indicator, disch ar ge yourself to a
ground.
Cleaning
Do not use water or water based products to clean
labels, or they will become illegible. Isopropyl alcohol
may be used to clean labels. A mild soap solution may
be used to clean other exterior surfaces of the product.
2.1 Installation Safety Requirements
Safety Symbols
Various symbols may be used on the in dicator. They
have the following meaning:
Equipment protected throughout by DOUBLE
INSULATION
Helpful hints
Personnel
Installation must only be carried out by suitably
qualified personnel in accordance with the instructions
in this handbook.
Enclosure of Live Parts
To prevent hands or metal tools from touc hi ng parts
that may be electrically live, the indicator must be
enclosed in an enclosure.
Caution: Live sensors
The indicator is designed to operate if the temperature
sensor is connected directly to an el ec trical heating
element. However, you must ensure that service
personnel do not touch connections t o these inputs
while they are live. With a live sensor, al l cables,
connectors and switches for connec ting the sensor
must be mains rated for use in 230Vac +15% CATII.
Wiring
It is important to connect the indicator in accordance
with the wiring data given in this guide. Take particular
care not to connect AC supplies to the low voltage
sensor input or other low level inputs and outputs.
Only use copper conductors for conn ec tions (except
thermocouple inputs) and ensure that the wiring of
installations comply with all local wiring regulations.
For example, in the USA, use NEC Class 1 wi ring
methods. In the UK, use the latest vers ion of the IEE
wiring regulations (BS7671).
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 f used
appropriately to protect the cabli ng to the units.
Operations Manual Series 3L
10
Voltage rating
The maximum continuous voltage applied between any
of the following terminals must not exceed 230Vac:
• 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 connec tion. Under fault
conditions, such a supply could ri s e above 240Vac
with respect to ground, and the produc t would not be
safe.
Conductive pollution
Electrically conductive pollut ion must be excluded from
the cabinet in which the indicator is mount ed. For
example, carbon dust is a form of elect rically
conductive pollution. To secure a suitable atmosphere
in conditions of conductive pollution, fit an air filter to
the air intake of the cabinet. Where con densation 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 shoc k, we recommend that
the shield of the temperature sensor be grounded. Do
not rely on grounding through the f ramework 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 c onstantly on
include:
• the temperature sensor becoming detac hed 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 being 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 t o 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 relax es to the alarm
condition when power is removed.
Installation requirements for EMC
To ensure compliance with the Europea n E MC
directive certain installation precautions are necessary
as follows:
• 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.
• 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 commerc i al and light
industrial emissions standard i s required. In this
case to meet the conducted emissions
requirement, a suitable mains filter should be
installed.
Routing of wires
To minimize 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, us e s hi elded cables
with the shield grounded at both ends. In general,
keep cable lengths to a minimum.

3.1.1 To Re-Enter Quick Code Mode
If you need to re-enter the ‘Quick Configuration’ m ode
this can always be done as follows:
1. Power down the indicator.
3.3 Front panel layout
2. Hold
button down and power up the indicat or
again. Keep the button pressed until you are
requested to enter a passcode.
3. Enter a passcode using the
or
buttons. In
a new indicator the passcode defau l ts to 4. If an
incorrect passcode is entered, you must repeat
the whole procedure.
Parameters may also be configured using a
deeper level of access as described in subsequent
chapters of this manual. If this has been done and the
Quick Code Mode is re-entered as descri bed above,
then the quick codes are shown with full stops (e.g.
G.S.2.G.A.) to indicate that the conf iguration has been
changed.
3.2 Pre-Configured Indicator or Subsequent Starts
A brief start up sequence consists of a self test in
which all elements of the display are illuminated and
the software version number is shown.
The indicator will briefly displa y the quick codes during
start up and then proceed to Operator Level 1.
You will see the display shown below. It is called the
HOME display.
If the Quick Codes do not appear during start up,
this means that the indicator has been configured in a
deeper level of access, as stated opposite. The quick
codes may then not be valid and are therefore not
shown.

the scrolling messages ‘ALARM 1 HIGH’ and ‘ALARM
4 LOW’ are shown together with the beac ons ‘ALM’,
‘OP1’ and ‘OP4’. ‘ALM’ flashes if the alarm has not
been acknowledged.
If the input sensor is broken ‘S.br’ appear s in the top
display and the scrolling message ‘INPUT SENSOR
BROKEN’ appears in the message center.

If the alarm is still present, the ALM beacon will light
continuously.
By default alarms are configured as non-latching, deenergized in alarm. If you require lat ched alarms,
please refer to the engineering handbook.
3.3.2 Out of Range Indication
If the input is too high, HHHHH will be displayed.
If the input is too low, LLLLL will be displayed.
3.3.3 Sensor Break Indication
An alarm condition (S.br) is indicated if the sensor or
the wiring between sensor and indicator becomes
open circuit.
For a PRT input, sensor break is indicated if any one of
the three wires is broken.
For mA input, sensor break will not be detected due to
the load resistor connected across the input terminals.
For Volts input, sensor break may not be detected due
to the potential divider network connec ted across the
input terminals.
3.4 Operator Parameters in Level 1
Operator level 1 is designed for day to day operation of
the indicator, and access to these parameters is not
protected by a pass code.
Press

4.3 FM and Alarm Units
!
Series 3L indicators supplied to Function code FM are
FM approved.
Series 3L indicators supplied to Function code DN are
approved to EN14597.
The instrument label is marked accordingly.
In these instruments, the alarm operating the AA relay
output is set to inverted and latching. This function
cannot be altered.
When the instrument is configured using the Quick
Start codes (section 3.1), Alarm 1 is used to operate
both Outputs 1 and 4 (AA relay). The Quick Start
configuration for the AA relay will enable and configure
Alarm 4 but Alarm 4 will not be used to operate Output
4.
If Quick Start is used to configure Alarm 1 as
a high alarm and Alarm 4 as a low alarm, then the
resulting configuration will be t hat the high alarm 1 is
used to drive both outputs 1 and 4. The low alarm 4
will not be connected to any output.
Further details on latching and blocking alarms can be
found in section 9.1.
