SAFETY NOTES

1.

Before any other connection is made, the protective earth terminal shall be connected to a protective conductor. The Mains (supply voltage) wiring must be terminated in such a way that, should it slip in the cable clamp, the Earth wire would be the last wire to become disconnected.

2.

In the case of portable equipment, the protective earth terminal must remain connected (even if the recorder is isolated from the mains supply), if any of the I/O circuits are connected to hazardous voltages*.

WARNING!

Any interruption of the protective conductor inside or outside the apparatus, or disconnection of the protective earth terminal is likely to make the apparatus dangerous under some fault conditions. Intentional interruption is prohibited.

Note: In order to comply with the requirements of safety standard BS EN61010, the recorder shall have one of the following as a disconnecting device, fitted within easy reach of the operator, and labelled as the disconnecting device.

a.

A switch or circuit breaker which complies with the requirements of IEC947-1 and IEC947-3 b.

A separable coupler which can be disconnected without the use of a tool c.

A separable plug, without a locking device, to mate with a socket outlet in the building

3.

The mains supply fuse within the power supply unit is not replaceable. If it is suspected that the fuse is faulty, the manufacturer's local service centre should be contacted for advice.

4.

Batteries within recorders are not user replaceable. Contact the manufacturer's local service centre if a problem is suspected.

5.

Whenever it is likely that protection has been impaired, the unit shall be made inoperative and secured against unintended operation. The nearest manufacturer's service centre should be consulted for advice.

6.

Any adjustment, maintenance and repair of the opened apparatus under voltage, should be avoided as far as possible and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.

7.

Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/filtering/sealing etc. must be installed in the recorder enclosure.

8.

Signal and supply voltage wiring should be kept separate from one another. Where this is impractical, shielded cables should be used for the signal wiring.

9.

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment might be impaired.

* A full definition of "Hazardous' voltages appears under 'Hazardous Live' in BS EN61010. briefly, under normal operating conditions, hazardous voltages are defined as > 30V RMS (42.2V peak) or > 60V dc.

100 MM RECORDER USER GUIDE

100 mm. RECORDER USER GUIDE

1 INTRODUCTION

The recorder comes in two versions - a continuous-trace recorder with up to four pens and a multipoint recorder giving up to six traces on the chart. Chart annotation is standard with the multipoint version, but is an optional extra

(specified at time of order) with the continuous trace recorder. When fitted, this annotator option prints time, date, scales and channel tags on the chart to simplify trace interpretation.

Designed to fit a DIN cutout (138 x 138 mm) the recorders feature an exceptionally small back of panel dimension of

220 mm. (no terminal cover) or 236 mm with cover.

The recorders are factory configured to customers' requirements, but chart speed and alarm setpoints can be adjusted by the operator, as can the zero and full-scale (span) positions of the pens or printhead.

ANNOTATOR BATTERIES

When the batteries associated with the Continuous Trace annotator option are fully charged, they will maintain the real-time clock for approximately one month (depending on temperature etc.), without power applied to the recorder.

The batteries are uncharged when despatched from the factory, and it takes approximately 175 hrs to charge them fully. Should power be removed from the recorder before this, the retention time will be reduced accordingly.

1.1 Unpacking the recorder

The recorder is despatched in a special pack designed to give adequate protection during transit. Should the outer box show signs of damage, it should be opened immediately and the recorder examined. If there is evidence of damage, the instrument should not be operated and the local representative contacted for instructions. After the recorder has been removed from its packing, the packing should be examined to ensure that all accessories and documentation have been removed. Once the recorder has been installed, any internal packing should be removed, and stored with the external packing, against future transport requirements.

2 INSTALLATION

2.1 MECHANICAL INSTALLATION

Figure 2.1 gives installation details.

The recorder is inserted through the panel aperture from the front of the panel. With the weight of the recorder supported, the panel clamps are inserted into one pair of the rectangular apertures (either at the top and bottom or at the right and left sides) of the recorder. The jacking screws are then be tightened sufficiently to clamp the recorder into position. EXCESS FORCE SHOULD NOT BE USED IN TIGHTENING THESE SCREWS.

2.2 ELECTRICAL INSTALLATION

Warning!

Refer to the safety notes on page 2 of this manual before proceding.

Figure 2.2 gives mains (line) and signal wiring information.

2.3 CHART REPLACEMENT

Notes

1.

If this is a multipoint recorder then for 'pens' read 'printhead'

2.

For recorders with status levels K13 or higher, if the cassette type (i.e. roll or z-fold) is changed, or if the recorder loses its configuration, the recorder must be reconfigured for the correct cassette type or the chart drive will not operate correctly. The manufacturer's local service centre should be contacted for advice

Park Pens

Open the door of the recorder and operate the two switches

(at bottom left and bottom right of the recorder) simultaneously for approximately one second, then release. (Do not expect anything to happen until you let go!)

This causes the pens to go to their park positions.

Once the chart has been replaced, return the cassette to the recorder and operate the two switches simultaneously for over four seconds (to return to normal operations) or for about one second if you wish to check the pens' zeros/spans against the new chart. See 'Setting up the recorder' below.

2.3.1 Z-Fold charts

Remove the cassette, by pulling on the two latches ('A' in the top figure). If a used chart is present, open the take-up retainer and remove the used chart.

Open the top of the paper pay-out tray, and remove any residual paper dust. Open the chart guide.

Unpack the replacement chart and fan it several times to separate the leaves and to remove as much perforation dust as possible.

Orient the chart so that the circular holes are to the left, the slots to the right, and the red end-of-chart line to the back

(all directions relative to the front of the cassette). Place the chart into the pay-out tray, unfolding three or four leaves at the same time. Pull the free end of the chart over the drive roller and down behind the chart guide and lay the free leaves in the take-up tray.

Ensure that the paper folds naturally into the tray, that the printed grid is uppermost and that the slots are at the right hand edge of the chart (i.e. the circular holes are to the left).

Close the take-up retainer and the chart guide, ensuring the paper holes/slots fit over the sprockets on the drive roller.

Close the top of the paper pay-out tray, ensuring that the chart is contained behind the flanges on the top.

Remove old chart

Fan new chart

Chart guide

Lay two or three leaves in take-up tray, ensuring they fold naturally. Close take-up retainer and chart guide.

2.4 CHANGING THE PENS/CARTRIDGE

Note: Care should be taken to avoid pen/cartridge contact with skin or clothing

2.4.1 Continuous-trace recorders

Open the recorder door, and the scale plate, both hinged at their left edge.

With power applied to the recorder, operate both push switches together, for between 1 and 2 seconds.

After the switches have been released, the pens will 'fan' to allow easy access.

Pull the pens forwards off their guide bars.

Fit the new pens and close the scale plate. Operate the switches simultaneously for over 4 seconds to return to normal recording, or for between 1 and 2 seconds to check the pen zeros and spans (section 2.5)

2.4.2 Multipoint recorders

Open the door and the scale plate, both hinged at their left edge.

With power applied to the recorder, operate both push switches simultaneously for between 1 and 2 seconds. After the switches are released, the printhead travels to the centre-chart position.

Remove the chart cassette and pull the exhausted print cartridge 'vertically' downwards out of its holder.

Offer up the new cartridge to the printhead, and push it upwards into place.

Return the chart cassette to the chassis. Operate the switches simultaneously for over 4 seconds to return to normal recording, or for between 1 and 2 seconds to check the printhead zeros and spans (section 2.5).

2.5 SETTING UP THE RECORDER

An auto-repeat feature is included in the recorder interface, so when a key has to be operated repeatedly, the key can be held continuously actuated instead if appropriate until the required number of increments has been achieved.

2.5.1 Continuous trace recorder with no annotator

Activating the two pushbutton switches for approximately 1 second causes the chart to stop and the pens to fan ready for replacement. Repeated operations of the right hand switch scrolls through the list below. At any point, a further

1 second operation of both keys simultaneously ('Enter') allows access to the parameter for adjustment using either or both the switches.

SETTING THE CHART SPEED

When chart speed is selected for setup, all the pens move to the centre of the chart except for pen 1 which drives to

40%, 45%, 50%, 55% or 60% of span according to the currently selected speed (40% = Chart drive off). The left and right switches can be used to move the channel 1 pen to the required chart speed position. A further simultaneous operation of the two switches causes the new chart speed to become operational.

Your recorder's chart speed range is defined at time of order. The speed range-number can be found on the configuration label on the bulkhead behind the chart cassette. Table 5.1 shows the speeds associated with that range.

SETTING THE PEN ZEROS AND SPANS

Each time a pen zero setup is selected all the pens move to 10% of chart width, except the selected pen which moves to 5%. A further enter drives this pen to where it thinks chart zero is. The left and/or right switches move the pen

0.15 mm left or right respectively each operation, allowing the pen to be aligned with the chart zero.

Similarly when a pen span is selected, all the pens move, to 90% of chart width except the selected pen which moves to 95%. After a further 'Enter', the selected pen moves to where it thinks chart span is. The left and/or right switches move the pen 0.15 mm left or right respectively each operation, allowing the pen to be aligned with the chart span.

SETTING ALARM THRESHOLDS (setpoints)

Each time an alarm 1 setup is selected all the pens move to 20% of chart width except the selected pen which moves to 15%. After a further 'Enter', the selected channel's pen will drive to its current set point. The left and/or right switches move the pen approximately 0.15 mm left or right respectively each operation, allowing the setpoint to be adjusted. A further simultaneous operation of the switches causes the new information to be saved, and alarm 2 to be moved to.

Similarly when an alarm 2 is selected for editing, all the pens move to 80% chart width except the selected pen which moves to 85%. After a further 'Enter', the selected pen moves to its current setpoint. The left and/or right switches move the pen 0.15 mm left or right respectively each operation, allowing the setpoint to be adjusted.

Your recorder's alarm types are defined at time of order and can be found on the label behind the cassette

RETURN TO RECORDING

At any time during setup, simultaneous operation of the two push switches for over 4 seconds returns the recorder to normal operation

3 OPTIONS

Up to four 1/2-width option boards can be fitted, as specified at time of order (i.e. options are not retro-fittable).

3.1 RELAY OUTPUTS

The relay output option comes in three versions, each of which uses a 1/2 - width circuit board. The relay specification for resistive loads is as given below. For inductive loads, contact life = resistive life x reduction factor in figure 3.1, in which F1 = measured on representative samples; F2 = typical values (according to experience)

Contact to ground 300V RMS or dc (basic insulation)

30,000,000 operations

Figure 3.1 Reduction factor for inductive loads

Each recorder channel has two alarm thresholds (alarm 1 and alarm 2), which can both be absolute high or absolute low as defined at time of order. If the channel's value lies above a high threshold, the relevant relay for that channel alarm is active. If the channel's value lies below a low threshold, the relay for that channel alarm is activated.

Notes:

1.

There is a 1% of span hysteresis built into the recorder so that if a high alarm becomes active at say, 78% of span, it will remain active until the value has returned to less than 77% of span. This prevents the alarm's continuously changing state when the channel's value is hovering about the threshold.

2.

The relays are de-energised in alarm and power off conditions, to provide fail-safe operation.

3.1.1 Three change-over relays board

This 1/2 board provides three change-over relays (i.e. with common, normally open and normally closed contacts).

100 MM RECORDER USER GUIDE

3.3 EVENT INPUT OPTION

This option offers four inputs to control chart on/off and annotation of events. Each event is initiated by a contact closure (or opening) applied between the 'C' terminal and input terminals one to four.

3.3.1 Contact input 1

With the contact closed, the chart runs normally, at its selected chart speed.

When the contact is opened, pens are parked at zero (continuous-trace recorders) or tracing is stopped (multipoint recorders), the chart winds forward eighty mm. and stops.

Contact input 1 may not be closed if contact input 2 (below) is closed.

3.3.2 Contact input 2

This function applies only to annotating recorders.

At closure, the current time and date is printed on the chart. For as long as the contact is closed, the chart runs at its selected speed, but annotation of scales, time, date and chart speed is inhibited.

At contact opening, pens are zeroed (contiuous-trace recorders) or tracing is inhibited (multipoint recorders), time, date, scales and chart speed are printed on the chart, the chart is wound forwards 80 mm. and is then stopped.

Contact input 2 may not be closed if contact input 1 is closed.

3.3.3 Contact input 3

This function applies only to annotating recorders, and is effective only if contact 1 or 2 is closed.

On closure, the message "

EVENT START HH:MM:SS

" is printed at the left-hand side of the chart, where

HH:MM:SS shows the time of closure in hours, minutes and seconds.

On contact opening, the message "

DURATION HH:MM:SS

" is printed at the left edge of the chart, where

HH:MM::SS shows how long the contact has been closed to the nearest second. Should the duration of closure reach 100 hours, the duration re-sets to zero.

3.3.4 Contact input 4

If contact 1 or 2 is closed, then channel four (continuous trace) or channel six (multipoint recorders) is used to show the status of contact closure 4. Whilst contact 4 is open, the trace is at 100% of chart span; whilst closed, the trace moves to 96% of span.

If neither contact 1 or 2 is closed, pen four (continuous-trace recorders) moves to chart zero or tracing by channel 6

(multi-point recorders) is stopped.,

6 GLOSSARY OF TERMS

Alarm

Analogue input

Attenuator

Break response

A function which is triggered when an input signal or a signal derived from it reaches a certain value. Once triggered, the alarm can cause a relay output to change state.

An input which changes in a smooth (non-stepped) way (e.g. thermocouples, resistance thermometers).

A resistive device which reduces the signal voltage by a known ratio (usually 100:1)

The recorder can detect an open circuit at its input terminals and, the instrument’s response to an open circuit can be defined as ‘None’, ‘Drive high’ or ‘Drive low’ at time of order. If none’ is selected the trace is allowed to drift according to what the input wiring is picking up

Chart cassette

(acting as an aerial). Drive high (low) causes the trace to be drawn at the extreme right (left) side of the chart.

A mechanical paper transport system for containing and feeding the chart past the pens or

printhead at a known speed. The cassette includes reservoirs for unused (pay-out tray) and used (take-up tray) sections of chart.

Cold Junction Compensation Also known by the abbreviation CJC. The voltage generated by a thermocouple (TC) junction depends on the temperature difference between the actual bonded junction (the hot junction), and the other (non-bonded) end of the conductors (the cold junction (CJ)). Thus, for

Configuration any reading from a TC to be accurate, the temperature of the CJ must be taken into account.

This can be done in three ways: Internal, External or Remote.

Internal. The recorder has integral temperature detectors measuring the temperature near the terminal blocks (the cold junction for directly connected TCs).

External. For remote TCs, the cold junction can be held at a known temperature. This temperature is entered (in degrees) as a part of the CJC configuration.

Remote. For remote TCs, an auxiliary temperature detector can be used to measure the cold junction temperature. This detector is then connected to a separate input channel. This input channel number is entered as a part of the CJC configuration.

This is used as a verb to mean ‘the process of telling your recorder what you want it to do’, and as a noun to mean ‘the way in which the recorder has been set up (or configured)’. For this recorder, most of the configuration is done by the manufacturer, leaving only simple selections (such as chart speed) to be made by the user.

6.GLOSSARY OF TERMS (Cont.)

Continuous trace

Digital (discrete) input

Event input

Hysteresis

This is used to describe recorders which have a single pen associated with each process

variable, and this pen traces the value continuously. See also multipoint recorder.

An input which has only two states (on or off). Examples are switch inputs or voltage pulse inputs.

A discrete (switch) or digital (voltage level) input.

When an input signal is ‘hovering’ near a setpoint, then an annoying and potentially damaging series of alarms can be generated, instead of just one alarm the cause of which can be dealt with if necessary. To avoid this, a ‘hysteresis’ value of 1% span is applied, which effectively puts a dead band round the set point. For example with a span of 0 to 1000 an absolute high alarm with a set point of 100 will have a hysteresis value of 10. The alarm is triggered when the input signal value rises above 100, but will not re-trigger until after the alarm has been ‘cleared’ by the process value falling below 90. An attempt to depict this example is given in the figure below.

Alarm with hysteresis

An input circuit which accepts voltage, current or digital input signals from the user.

A voltage, current or digital input applied to the recorder input circuits. See also Analogue input and Digital (discrete) input.

Most transducers produce an output which is not directly proportional to the input. For example, the voltage output from a thermocouple does not vary linearly with the temperature it is exposed to. The recorder uses a ‘look-up’ table to find a temperature value for any mV input from a specified thermocouple type. Similar tables exist for other transducers such as resistance thermometers.

An umbrella term which means: the value of an input channel, derived channel, totaliser,

counter, timer etc. measured in mathematical units as a proportion of the span. See also

Process variable.

This is used to describe recorders which have multiple pen printheads rather than individual pens to produce the trace on the chart. Each trace is made up of dots, produced by the printhead as it traverses across the chart at regular intervals. Advantages are that many more traces can be laid down on the chart, the traces can be annotated for identification and messages can be printed on the chart. Disadvantages are that fast transients may be missed at low chart speeds.

A term used to describe the controls (e.g. pushbuttons, keypads) that are used to operate and configure the unit.

This includes the chart cassette and the mechanical system, motors etc. needed to move the chart through the cassette. The paper transport system is often considered to be an integral part of the writing system.

A fibre-tipped disposable stylus with an integral ink reservoir. Used to draw (trace) the value of a single process variable on the chart in continuous trace recorders.

With modular recorder designs, each pen has its own mechanical system (including motor and feedback device) associated with it to drive it backwards and forwards across the chart.

Pen tray is the general term for such mechanical systems. With some recorders, the pen drive electronics are integral with the pen tray.

This is a device which, together with a disposable multi-colour cartridge, allows multi-point recorders to mark the chart.

An umbrella term which means: the value of an input channel, derived channel, totaliser,

counter, timer etc. measured in engineering units (e.g. Degrees Celsius). See also Measured value.

Relay output A set of contacts which changes state as a result of an alarm becoming active. Relays are energised continuously except when ‘in alarm’, so that if power to the recorder fails they go

Resistance thermometer into their ‘alarm’ state.

Also known as a resistance temperature detector (RTD), a resistance thermometer is constructed of a material whose resistance varies in a known way on the temperature it is exposed to. The resistance variation is non-linear, but for any given type, this non-linearity is

Setpoint

Shunt well known and invariable and is compensated for by linearisation tables in the recorder memory.

Also known as ‘threshold’, this is the point at which an alarm becomes active or inactive.

See also hysteresis.

The input circuit of each recorder channel measures voltage signals. If current signals are connected to the recorder, a low value resistor must be placed across the inputs, to convert the current signal to Volts, according to Ohms law (Volts = Amps x Ohms). Thus, a 0 to

20 mA (0.02 Amps) signal applied across a 250

Ω

resistor produces a voltage range of

0 to (0.02 x 250) Volts = 5 Volts.

Such resistors are called ‘Shunt resistors’ or ‘Shunts’ for short, and are usually of very close

Zero tolerance.

Span has two common meanings: the right-most grid of the chart, or the value given by

(maximum value - minimum value). The two meanings are identical where the minimum value is zero.

The line produced on the chart or display screen showing the value of the process variable being measured.

A junction of two dissimilar metals which produces a small voltage, the value of which depends on the temperature of the junction. The voltage varies in a non-linear way with temperature, but for any given type, this non-linearity is well known and invariable and is compensated for by linearisation tables in the recorder memory.

See setpoint.

A device which produces an electrical output proportional to temperature, flow rate, pressure, speed, position etc. Common transducers are potentiometers, thermocouples, resistance

thermometers (RTDs) and flow meters.

Thermocouple wire (compensation wire) is expensive, and if the thermocouple is a long way from the measuring device, it is often cheaper to instal a ‘transmitter’ local to the thermocouple. This device converts the mV signal from the thermocouple to a mA signal which can then be wired to the recorder using normal copper wire. Transmitters can be self powered, or they may need power generated for them. Most recorders can be fitted with Transmitter Power Supplies as an option.

A general term used to describe the mechanical means of moving pens/printheads across the chart width. The term often includes the paper transport system used to drive the chart through the cassette.

Zero is generally taken to mean the value associated with the left-most grid line on the chart.

Its actual value need not be zero, as long as it is less than the Span value.
