Crompton Instruments 1

1 IntroductionThe Crompton Integra 1540 Display is a panel mounted display that works in conjunction with theIntegra 1560 or 1580 Digital Transducer.

This two part system will measure display 31and communicate up to 51 electrical parameters,integrating high accuracy measurement technology with the simplicity and visibility of 7 segment LEDdisplays.

For installation where no display is required, all set up configuration isachieved via the DIS-1540 interface.

The display is available in only one configuration.

The Integra 1540 Display front panel has two push buttons, referred toas “keys”. The two keys take the user through the menu structure withease and simplicity, to display and configure to their individualrequirements.The measurements available via the display used in conjunction withthe Integra Transducer are shown in the table below.

2 Installation

2.1 DisplayThe Integra 1540 Display may be mounted in a panel of any thickness up to a maximum of 0.4".Mounting is by four ¼ - 2 8 U N F corner studs and nuts. Consideration should be given to the spacerequired behind the instrument to allow for bends in the connection cables.As the enclosure conforms to IP54 it is protected from water spray. Additional protection to the panelmay be obtained by the use of an optional panel gasket. The terminals at the rear of the productshould be protected from liquids.The Integra 1540 Display should be mounted in a reasonably stable ambient temperature within therange -20 to +70°C. Vibration should be kept to a minimum and the product should not be mountedwhere it will be subjected to excessive direct sunlight.

WARNINGS:• In the interest of safety and functionality these products must be installed by a qualified

engineer, abiding by any local regulations.• Voltages dangerous to human life are present at some of the terminal connections of

these units. Ensure that all supplies are de-energised before attempting any connection ordisconnection. External installations must be sufficient to protect human life andequipment under fault conditions.

• These products do not have internal fuses therefore external fuses must be used forprotection for safety under fault conditions.

2.2 EMC Installation RequirementsThese products have been designed to meet the certification of the EU directives when installed to agood code of practice for EMC in industrial environments, e.g.• Screened output and low signal input leads. Other connecting leads must be screened or have

provision for fitting RF suppression components, such as ferrite absorbers, line filters etc., if RFfields cause problems. N.B. It is good practice to install sensitive electronic instruments, that areperforming critical functions, in EMC enclosures that protect against electrical interferencecausing a disturbance in function.

• Avoid routing leads alongside cables and products that are, or could be, a source of interference.• To protect the product against permanent damage, surge transients must be limited to 2kV peak.

It is good EMC practice to suppress differential surges to 2kV at the source. The unit has beendesigned to automatically recover in the event of a high level of transients. In extremecircumstances it may be necessary to temporarily disconnect the auxiliary supply for a period ofgreater than 5 seconds to restore correct operation.

• The current inputs of these products are designed for connection into systems via currenttransformers only.

3.15 Over RangeThe displayed values must be in the range –999 x 1000 to 9999 x 1000.

While operating within the specified range, the displayed value will not over range for positive values.

Whilst displaying negative values the display will overflow for values more negative than –999 x 1000,this situation will be indicated by displaying four bars in the appropriate line:

Value on middle line has overflowed.



3.16 kW.h and kVAr.h Display RangeThe kW.h and kVAr.h display range is limited to 9999999. If the unit is allowed to increment beyondthis value the count will continue to be updated in the measurement unit but the display will change toseven bars. The counter will register from a count of 1 kW.h kVAr.h to a maximum of 9,999,999.

The value will continue to be available via the Modbus output.

3.17 Error MessagesThe display screen repeatedly requests new values from the measurement processor, if there is aproblem obtaining these values the display will continue to retry but will alert the user by displaying themessage Err1. This message may be seen briefly during conditions of extreme electromagneticinterference with the normal display returning once the interference has ceased.

If the Err1 message persists a short interuption to the auxiliary supply may restore normal operation.
