Isolated output 300Vac CATII
Contact rating:: 2A 264Vac resis tive
Output functions: Alarm/Event
* 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/100). 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.

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.

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.

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.

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.

5. Access to Further Parameters

Parameters are available under different levels of security and are defined as Level 1 (Lev1), Level 2 (Lev2), Level 3 (Lev 3) and Configuration (Conf). Level 1 has no pass code since it contains a minimal set of parameters generally sufficient to run the process on a daily basis. Level 2 allows access t o parameters which may used in commissioning an indicator or settings between different products or batches. This has been described in the previous section.
Level 3 and Configuration level parameters are also available as follows:

5.1 Level 3

Level 3 makes all operating parameters available and alterable (if not read only). It is typically used when commissioning an indicator.
Examples are: Range limits, setting alarm levels, communications
address.

5.2 Configuration Level

This level makes available all par ameters including the operation parameters so that there is no need to switch between configuration and operati on levels during commissioning. It is designed for those who may wish to change the fundamental characteristics of t he instrument to match the process.
Examples are: Input (thermocouple type); Alarm type;
Communications type.
WARNING
Configuration level gives access to a wide range of parameters which match the indicator to the process. Incorrect configuration could result in damage to the process and/or person al injury. It is the responsibility of the person commissioning the process to ensure that the configuration is correct. In configuration level, the indicator is not providing alarm indication.
Do not select configuration level on a live process.

6.1.3 PV Offset

All ranges of the indicator have been calibrated against traceable reference standards . This means that if the input type is changed it is not necessary to calibrate the indicator. There may be occasions, however, when you wish to apply an offset to the standard calibration to take account of known errors within th e pr ocess, for example, a known sensor error or a known error due to the positioning of the sensor. In these i ns tances it is not advisable to change the referenc e ( factory) calibration, but to apply a user defined offset.
PV Offset applies a single offset t o the temperature or process value over the full display range of the indicator and can be adjusted in Level 3. It has the effect of moving the curve up a down about a central point as shown in the example below:-

It is also possible to apply a five point offset which adjusts both low and high points. T his is done in Level 3 using the CAL List, and the procedure is described in the Calibration section 1212.2.1.

6.1.4 PV Input Scaling

Input scaling applies to the linear m V and volts input ranges only. This is set by configuring the INPUT TYPE parameter to mV or VoLt, mV has an input range of –10 to 80mV. Using an external burden resistor of
2.49, the indicator can be made to accept 4-20mA from a current source. Scaling of the input will match the displayed reading to the electri c al input levels from the transducer. PV input scaling can only be adjusted in Configuration level and is not pr ovided for direct thermocouple or RTD inputs.
The graph below shows an example of input scaling, where it is required to display 2.0 when the input is 4mV and 500.0 when the input is 20mV .
If the input exceeds +5% of the inp.Lo or inp.Hi settings, sensor break will be displayed.

9.1.1 Alarm Relay Output

Alarms can operate relay outputs 1, 3 or 4. Any individual alarm can operate an in dividual output or any combination of alarms, up to four, can op er ate an individual output. They are either supplied pre­configured in accordance with the or der ing code or set up in the Quick Codes or in configur ation level.
Section7.1. describes how to configure the alarm outputs using the ‘SOURCE’ parameters.

9.1.2 Alarm Indication

ALM beacon flashing red = a new alarm
(unacknowledged)
This is accompanied by a scrolling alarm
message. A typical default message will show the source of the alarm followed by the t ype of alarm. For example, ‘ALARM 1 HIGH’
If more than one alarm is present further
messages are flashed in turn in the main display. The alarm indication will continue while the alarm condition is present and is not acknowledged.
ALM beacon on continuously = alarm has been
acknowledged.

9.1.3 To Acknowledge An Alarm

This state will continue for as long as the alarm condition remains. When the alarm condition disappears all indication also di s appears.
If a relay has been attached to the alarm output, it will de-energize when the alarm condition occurs and remain in this condition until ack nowledged or the alarm is no longer present.
If the alarm condition disappears bef or e i t is acknowledged the alarm resets immediately.

Cycle
The response of an alarm after a power cycle depends upon the latching type, whether it has been configured to be a blocking alarm, it's state and the acknowledge status of the alarm.
The response of active alarms after a power cycle is as follows:
For a non-latching alarm or an event alarm blocking will be re-instated, if configured. If bl oc king is not configured the active alarm will remain active. If the alarm condition has gone safe during the down time the alarm will return inactive.
For an auto-latching alarm blocking will be re-instated, if configured, only if the alarm had been acknowledged prior to the power cycle. If blockin g i s not configured or the alarm had not been acknowledged the active alarm will remain active. If the alarm condi tion has gone safe during the downtime the alarm will return inactive if it had been acknowledged prior to t he power cycle else it will return safe but not ac knowledged. If the alarm was safe but not acknowledged prior to the power cycle the alarm will return safe but not acknowledged.
For a manual-latching alarm blocki ng will not be re­instated and the active alarm will rem ai n active. If the alarm condition has gone safe during the downtime the alarm will return safe but not acknowledged. If the alarm was safe but not acknowledged pr ior to the power cycle the alarm will return safe but not acknowledged.

11. Di gital Communications

Digital Communications (or ‘comms’ for short) allows the indicator to communicate with a PC or a networked computer system.
This product conforms to MODBUS RTU  protocol a full description of which can be found on www.modbus.org.
Two ports are available both using MODBUS RTU communication facilities:
1. a configuration port - intended to communicate with a system to download the instrument parameters and to perform manufactur i ng tests and calibration
2. an optional EIA 485 port on terminals HD, HE and HF - intended for field communicati ons using, for example, a PC running a SCADA package.
The two interfaces cannot operate at the same time. Each parameter has its own unique ModB us address.
A list of these is given at the end of this sect ion.

11.1 Digital Communications Wiring

11.1.1 EIA 485

To use EIA 485, buffer the EIA 232 port of the PC with a suitable EIA 232/RS485 converter. The use of an EIA 485 board built into the computer is not recommended since this board may not be isolated, which may cause noise problems, and the RX terminals may not be biased correctly for this application.
To construct a cable for EIA 485 operati on use a screened cable with one (EIA 485) twiste d pair plus a separate core for common. Althoug h common or screen connections are not necessary, their use will significantly improve noise immunity.
The terminals used for EIA 485 digital communications are listed in the table below.

Broadcast master communications, as a simple master, allows the Series 3L indicator to send a single value to any number of slave instruments. Modbus broadcast using function code 6 (Write single v alue) must be used. This allows the Series 3L to link with other products, without the need for a supervisory PC, to create a small system solution. The f acility provides a simple and precise alternative t o anal ogue retransmission.
The retransmitted parameter is P r ocess Variable. The indicator will cease broadcast when it receives a valid request from a Modbus master.
Warning
When using broadcast master communications, bear in mind that updated values are sent man y ti m es a second. Before using this facility, check that the instrument to which you wish to send values can accept continuous writes. Note that the SSI Series 3L does
not accept continuous writes to the temperature setpoint. Damage to the internal non-volatile memory could result from the use of this function. If in any doubt, contact the manufacturer of the device in question for advice.
When using the 3L series indicator fitted with software version 1.10 and greater, use the Remot e Setpoint variable at Modbus address 26 if you need to write to a temperature setpoint. This has no write restrictions and may also have a local trim value applied.

11.2.2 Broadcast Master Communications

The Series 3L broadcast master can be c onnected to up to 31 slaves if no segment repeaters are used. If repeaters are used to provide additional segments, 32 slaves are permitted in each new segment . The master is configured by setting the ‘RE TRAN’ parameter to
PV.
Once the function has been enabled, t he instrument will send this value out over the communications link every control cycle (250ms).
Notes:-
1. The parameter being broadca s t must be set to the same decimal point resolution in both master and slave instruments.
2. If any Modbus master, is connected to the port on which the broadcast master is enabled, then the broadcast is temporarily inhibi ted. It will restart approximately 30 seconds after t he m aster is removed.

11.4 DATA ENCODING

Modbus data is normally encoded into a 16 bit signed integer representation.
Integer format data, including any value without a decimal point or represented by a text ual value (for example ‘off’, or ‘on’), is sent as a simple integer value.
For floating point data, the value is represented as a ‘scaled integer’, in which the value is sent as an integer which gives the result of the value multiplied by 10 to the power of the decimal resolution for that value. This is easiest to understand by refer ence to examples:
FP Value Integer Representation
9. 9
-1.0 10
123.5 1235
9.99 999
It may be necessary for the Modbus master to insert or remove a decimal point when using these values.

All ranges are calibrated during man ufacture to traceable standards for every input type. When changing ranges it is not necessary to calibrate the indicator. Furthermore, the use of a continuous automatic zero correction of the input ensures that the calibration of the instrument is optimized during normal operation.
To comply with statutory procedures such as the Heat Treatment Specification AMS2750, the calibration of the instrument can be verified and re­calibrated if considered necessary in accordance with the instructions given in this chapter.
For example AMS2750 states:-
"Instructions for calibration and recalibration of ‘field test instrumentation’ and ‘control monitori ng a nd recording instrumentation’ as defined by the NADCAP Aerospace Material Specification for pyrometry AMS2750D clause
3.2.5 (3.2.5.3 and sub clauses) including Instruction for the application and removal of off sets defined in clause
3.2.4”.

12.1 To Check Input Calibration

The PV Input may be configured as mV, mA, thermocouple or platinum resistance thermometer.

12.1.1 Precautions

Before checking or starting any cal i bration procedure the following precautions shou ld be taken:-
1. When calibrating mV inputs mak e sure that the calibrating source output is set to less than 250mV before connecting it to the mV terminals. If accidentally a large potential is applied (even for less than 1 second), then at least one hour should elapse before commencing the calibration.
2. RTD and CJC calibration must not be carried out without prior mV calibration.
3. A pre-wired jig built using a spare instrument sleeve may help to speed up the calibration procedure especially if a number of instruments are to be calibrated.
4. Power should be turned on only after the instrument has been inserted in the sleeve of the pre-wired circuit. Power shou ld al so be turned off before removing the instr ument from its sleeve.
5. Allow at least 10 minutes for the instrument to warm up after switch on.

12.1.2 To Check mV Input Calibration

The input may have been configured for a process input of mV, Volts or mA and scaled in Level 3 as des cribed in section 5. The example described in section 6.1.4 assumes that the display is set up to read 2.0 for an input of 4.000mV and 500.0 for an input of 20.000mV.
To check this scaling, connect a milli-volt source, traceable to national standards, to terminals V+ and V­using copper cable as shown in the diagram below.
Source
Ensure that no offsets (see sections 6.1.3 and 12.2) have been set in the indicator.
Set the mV source to 4.000mV. Check t he display reads 2.0 +0.25% + 1LSD (least significant digit).
Set the mV source to 20.000mV. Check t he display reads 500.0 +0.25% + 1LSD.

12.1.3 To Check Thermocouple Input Calibration

Connect a milli-volt source, traceable to national standards, to terminals V+ and V- as shown in the diagram below. The mV source must be capable of simulating the thermocouple cold junction temperature. It must be connected to the instrument using the correct type of thermocouple compensating c able for the thermocouple in use.
Compensating cable
Set the mV source to the same thermocouple type as that configured in the indicator.
Adjust the mV source to the minimum range. For a type J thermocouple, for example, the minimum range is ­210OC. However, if it has been restricted using the Range Low parameter then set the mV source to this limit. Check that the reading on the display is within +0.25% of minimum range + 1LSD.
Adjust the mV source for to the maximum range. For a type J thermocouple, for example, the maximum range is 1200OC. However, if it has been restricted using the Range High parameter then set the m V source to this limit. Check that the reading on the display is within +0.25% of maximum range + 1LSD.
Intermediate points may be similarly checked if required.

12.2 Offsets

The process value can be offset to tak e i nto account known errors within the process. The offset can be applied to any Input Type (mV, V, mA, thermocouple or RTD).
A single offset can be applied - the proc edure is carried out in the
6.1.3. It is also possible to adjust the low and high points as a
five point offset. This can only be done in Level 3 in the ‘

12.2.1 Five Point Offset

A five point offset may be used to compensate for transducer or measurement non-linearities. The diagram shows an example of the type of discontinuity which might occur in a system.
In this case adjust each point in tur n for the VALUE WHICH THE INDICATOR SHOULD READ. For example if the value at point 1 should be 1. 2345 then set Pnt.1 to this value. The following example shows how to do this.

If the calibration is not within the specified accuracy follow the procedures in this sect ion:
In Series 3L series instruments, inputs which can be calibrated are:
mV Input. This is a linear 80mV range calibrated at two fixed points. This should always be done before calibrating either thermocouple or resistance thermometer inputs. mA range calibration is included in the mV range.
Thermocouple calibration involves calibrating the temperature offset of the CJC sensor o nly. Other aspects of thermocouple calibration are also included in mV calibration.
Resistance Thermo meter. This is also carried out at two fixed points - 150and 400Ω.

12.3.1 To Calibrate mV Range

Calibration of the mV range is carried out using a 50 milli-volt source, connected as shown in the diagram below. mA calibration is included in this procedure.
For best results 0mV should be calibrat ed by disconnecting the copper wires from the mV source and short circuiting the input to the indicator
