Ensuring the degree of protection

Compliance with the following points is mandatory following installation in the field orservicing in order to ensure that IP67 protection is maintained:• The transmitter must be mounted in a terminal head with the appropriate degree ofprotection.
• The housing seals must be clean and undamaged when inserted into their grooves. The
seals must be dried, cleaned or replaced if necessary.
• The connecting cables used must have the specified external diameter (e.g. M20x1.5,
cable diameter 8 to 12 mm).
• Firmly tighten the cable gland. →  14,  22
• The cables must loop down before they enter the cable glands ("water trap"). This meansthat any moisture that may form cannot enter the gland. Install the device in such a waythat the cable glands are not facing upwards. →  14,  22
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.

Secure the cover back onto the terminal head or field housing.

Switching write protection on/off
Write protection is switched on and off via a DIP switch on the rear of the optional
attachable display. When write protection is active, parameters cannot be modified. A locksymbol on the display indicates that write protection is on. Write protection prevents any
write access to the parameters. Write protection remains active even when the display isremoved. To deactivate write protection, the display must be attached to the transmitterwith the DIP switch switched off (WRITE LOCK = OFF). The transmitter adopts the setting
during operation and does not need to be restarted.
Turning the display
The display can be rotated 180° using the "DISPL. 180°" DIP switch.

Operation options

User roles
Endress+Hauser's role-based access concept consists of two hierarchical levels for the user
and presents the various user roles with defined read/write authorizations derived fromthe NAMUR shell model.
• Operator
The plant operator can only change settings that do not affect the application - andparticularly the measuring path - and simple, application-specific functions that are usedduring operation. The operator is able to read all the parameters, however.
• Maintenance
The Maintenance user role refers to configuration situations: commissioning andprocess adaptations as well as troubleshooting. It allows the user to configure andmodify all available parameters. In contrast to the Operator user role, in the
Maintenance role the user has read and write access to all the parameters.
• Changing the user role
A user role - and therefore existing read and write authorization - is changed by
selecting the desired user role (already pre-selected depending on the operating tool)and entering the correct password when subsequently prompted. When a user logs out,system access always returns to the lowest level in the hierarchy. A user is logged out
either by actively selecting the logout function when operating the device or is logged
out automatically if the device is not operated for a period of over 600 seconds.
Irrespective of this, actions that are already in progress (e.g. active upload/download,
data logging, etc.) continue to be executed in the background.
• As-delivered state
The Operator user role is not enabled when the device is delivered from the factory, i.e.
the Maintenance role is the lowest level in the hierarchy ex-works. This state makes it
possible to commission the device and make other process adaptations without having toenter a password. Afterwards, a password can be assigned for the Maintenance userrole to protect this configuration. The Operator user role is not visible when the device isdelivered from the factory.
• Password
The Maintenance user role can assign a password in order to restrict access to device
functions. This activates the Operator user role, which is now the lowest hierarchy level
where the user is not asked to enter a password. The password can only be changed or
disabled in the Maintenance user role. A password can be defined at different points inthe operation of the device:

Sensor-transmitter matching
RTD sensors are one of the most linear temperature measuring elements. Nevertheless,the output must be linearized. To significantly improve temperature measurement
accuracy, the device allows the use of two methods:• Callendar-Van Dusen coefficients (Pt100 resistance thermometer)
The Callendar-Van Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter inorder to improve the accuracy of the measuring system. The coefficients for a standard
sensor are specified in IEC 751. If no standard sensor is available or if greater accuracy isrequired, the coefficients for each sensor can be determined specifically with the aid ofsensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistancethermometers (RTD). The exact values of the coefficients derive from the calibration
data and are specific to each sensor. The sensor-specific coefficients are then sent to thetransmitter.
Sensor-transmitter matching using one of the methods mentioned above significantly
improves the temperature measurement accuracy of the entire system. This is because thetransmitter uses the specific data pertaining to the connected sensor to calculate themeasured temperature, instead of using the standardized sensor curve data.
