6 Product Pillars

to meet your every need

With our innovative, patented technologies, we make signal conditioning smarter and simpler. Our portfolio is composed of six product areas, where we offer a wide range of analog and digital devices covering over a thousand applications in industrial and factory automation. All our products comply with or surpass the highest industry standards, ensuring reliability in even the harshest of environments and have a 5-year warranty for greater peace of mind.

Individually outstanding, unrivalled in combination

Our range of temperature transmitters and sensors provides the highest level of signal integrity from the measurement point to your control system. You can convert industrial process temperature signals to analog, bus or digital communications using a highly reliable point-to-point solution with a fast response time, automatic selfcalibration, sensor error detection, low drift, and top EMC performance in any environment.

Our unique range of single devices covering multiple applications is easily deployable as your site standard. Having one variant that applies to a broad range of applications can reduce your installation time and training, and greatly simplify spare parts management at your facilities. Our devices are designed for long-term signal accuracy, low power consumption, immunity to electrical noise and simple programming.

We provide inexpensive, easy-to-use, future-ready communication interfaces that can access your PR installed base of products. The detachable 4501 Local Operator Interface (LOI) allows for local monitoring of process values, device configuration, error detection and signal simulation. The next generation, our 4511 Remote Operator Interface (ROI) does all that and more, adding remote digital communications via Modbus/RTU, while the analog output signals are still available for redundancy. With the 4511 you can further expand connectivity with a PR gateway, which connects via industrial Ethernet, wirelessly through a Wi-Fi router or directly with the devices using our Portable Plant Supervisor (PPS) application. The PPS app is available for iOS, Android and Windows.

Our display range is characterized by its flexibility and stability. The devices meet nearly every demand for display readout of process signals, and have universal input and power supply capabilities. They provide a real-time measurement of your process value no matter the industry, and are engineered to provide a user-friendly and reliable relay of information, even in demanding environments.

We deliver the safest signals by validating our products against the toughest safety standards. Through our commitment to innovation, we have made pioneering achievements in developing I.S. interfaces with SIL 2 Full Assessment that are both efficient and cost-effective. Our comprehensive range of analog and digital intrinsically safe isolation barriers offers multifunctional inputs and outputs, making PR an easy-to-implement site standard. Our backplanes further simplify large installations and provide seamless integration to standard DCS systems.

Our compact, fast, high-quality 6 mm isolators are based on microprocessor technology to provide exceptional performance and EMC-immunity for dedicated applications at a very low total cost of ownership. They can be stacked both vertically and horizontally with no air gap separation between units required.

Optical buttons

The user interface features 3 optical buttons: , 2 and . The buttons can be operated both with or without gloves1. The buttons are immune to interference from ambient light sources and other panel meters (e.g. other 7501 devices mounted in close proximity). Additionally, the optical buttons are adaptive, meaning that they will adapt to wear and e.g. dirt left on the surface. The buttons work both with and without a front cover mounted. If a rapid increase in optical reflection occurs, e.g. from mounting the cover or from dust/dirt on the glass, the buttons may activate. If a key-press is detected for a period of more than 70 seconds, it is assumed to be a failure key-press and the adaptive functionality will re-initialize in order to restore correct keypad functionality. This re-initialization can also be done by repowering the device.

Operating the optical buttons

The optical buttons are used for operating and programming the 7501. They offer multi-functionality depending on whether you press or long-press them. With the exception of the calibration and simulation menus (see the section Display menu), the display will return to the monitor view if no key-press is registered within one minute.

 In monitor view: switch to next process variable.

Elsewhere: increase the value of the selected parameter (except if device is write-protected).

Key presses are reflected in the symbols bar with the following symbols:

Up button is pressed

Down button is pressed

Enter button is pressed

Display

The 96 x 64 pixel display can be rotated in 90-degree increments for easy vertical or horizontal viewing. The adjustable backlight enables you to view process values in all lighting conditions without an external light source, and it can be configured to flash if an error occurs. Both the optional backlight and the flashing error backlight can be selected as red or white, or turned off completely.

Display views

The appearance of the display will change to reflect the state of the 7501. This allows for easy and intuitive operation, status indication and guides you in configuring the device.

1 Dark colored gloves can cause reduced sensitivity. 2 If error color (see the section Display menu) is set to red or white and the display backlight is flashing, the first key press cancels the flashing

backlight.

Changing the HART protocol version

It is possible to change the HART protocol revision of the device by means of the display, utilizing the PReset software and a HART modem or other HART configuration tools such as handheld HART terminals.

Changing the HART revision using the display and the optical buttons

Changing the revision is done from the HART revision view under the Advanced menu. Use the  or 2 optical buttons to select the desired HART revision. Press the  button to accept the revision and change to the Save view. Select Yes and press

 to acknowledge the change or No to cancel.

Changing the HART revision using the PReset software

Select either 7501H5 or 7501H7 depending on which protocol revision the 7501 is currently running. Click on the HART tab and then on Device Password / Write Protection / Protocol…. In the newly opened window check the “Change protocol to HART #” (# being the desired revision) then acknowledge by pressing the OK button.

The following warning appears:

Click Yes to accept the changes.

Changing the HART revision using a handheld terminal

• Drive the 7501 device Online and enter Device setup – Diag/Service.

• Select Write protection and Write protect by entering “********” (eight stars).

• Select New password - type “********” (eight stars) and then “HARTREV5” or “HARTREV7” depending on the desired revision

• Select Write enable and enter “-CHANGE-”.

7501V107-UK 39

Connection of transmitters in multidrop mode

The outputs of maximum 63 transmitters can be connected in parallel for a digital HART 7 communication on 2-wires. For HART 5 the outputs of maximum 15 transmitters can be connected in the same way.

Before they are connected, each transmitter must be configured with a unique polling address ranging from one to 63 (HART

7) or 15 (HART 5). If two transmitters are configured with the same address, both will be excluded. The transmitter must be configured for multidrop mode (with a fixed output signal of 4 mA). The maximum current in the loop is therefore 252 mA (HART 7) or 60 mA (HART 5).

The communication is done by means of either a HART communicator or a HART modem.

The PReset configuration software can configure the individual transmitter for multidrop mode and provide it with a unique polling address.

The HART communicator or HART modem can be connected across AB or BC.

Retrofit

The 7501 can be retrofitted with any 5335 or 5337 transmitter. This allows for easy use of existing devices. The following gives you a short guide on how to perform this task.

Before proceeding please refer to the section Assembly and disassembly for information on extracting and reassembling the main unit. Then follow the three easy steps below.

NB. The fixation bracket (marked B on the drawing) is not interchangeable between the aluminum and stainless steel housing. Check the bottom right-hand corner for identifier (Al for aluminum and RF for stainless steel).

1. On the 5335 / 5337, remove the terminal 1 and 2 screws using a screwdriver.

2. Attach the connector pins to the 5335 / 5337 connector 1 and 2.

Tighten the screws using a nutdriver or a socket wrench with Across Flats (A/F)

of 5 mm and an outer diameter of no more than 7 mm. Screw torque on connector pins = 0.4 Nm.

3. Mount the device in the main unit, making sure the connectors meet.

The first time power is applied to the retrofitted 7501, it will synchronize with the configuration parameters from the attached 5335 / 5337. This process will take approximately 30 seconds and during this NEW.DEV will appear in the display.

Warning:

For Ex installation the customer must assure that the installed transmitter has all the necessary approvals applicable for the place of installation. Once a 5335 / 5337 unit which has been fitted into the 7501, it must not be taken out and used in other applications.

The entity concept

The Transmitter must be installed according to National Electrical Code (ANSI-NFPA 70) and shall be installed with the enclosure, mounting, and spacing segregation requirement of the ultimate application.

Equipment that is FM-approved for intrinsic safety may be connected to barriers based on the ENTITY CONCEPT. This concept permits interconnection of approved transmitters, meters and other devices in combinations which have not been specifically examined by FM, provided that the agency's criteria are met. The combination is then intrinsically safe, if the entity concept is acceptable to the authority having jurisdiction over the installation.

The entity concept criteria are as follows:

ices, other than barriers, must not be a source of power.

The maximum voltage Ui(V

MAX

) and current Ii(I

MAX

), and maximum power Pi(Pmax), which the device can

receive and remain intrinsically safe, must be equal to or greater than the voltage (Uo or V

OC

or Vt) and

current (Io or I

SC

or It) and the power Po which can be delivered by the barrier.

The sum of the maximum unprotected capacitance (C

i

) for each intrinsically device and the interconnect-

ing wiring must be less than the capacitance (C

a

) which can be safely connected to the barrier.

The sum of the maximum unprotected inductance (L

i

) for each intrinsically device and the interconnecting

wiring must be less than the inductance (L

a

) which can be safely connected to the barrier.

The entity parameters Uo,V

OC

or Vt and Io,ISC or It, and Ca and La for barriers are provided by the barrier

manufacturer.

For Class II and Class III installations where rigid conduit is not used, seal cable entries against dust and fibres using a NRTL listed cable gland fitting.
