turbulent conditions exist. It can also be used to provide optimum signal conditions on foaming
materials. See Dielectric constant of material measured in Performance (Page 213) for more
information.
● The pipe diameter must be matched with the antenna size. Use the largest antenna size that
will fit the stillpipe/bypass pipe1). See Threaded Horn dimensions (Page 221), Raised-Face
Flange per EN 1092-1 (Page 255), Flanged encapsulated dimensions or Hygienic
encapsulated dimensions.
● One continuous length of metallic pipe is preferred, without joints.
● Any false reflections created by joints/welds/imperfections will lead to inaccuracies of the
measurement.
● Joints (if unavoidable) must be machined to ± 0.25 mm (± 0.010") and must have welded
connecting sleeve on the outside.
● If using any hygienic process connections in conjunction with a stillpipe/bypass, please
ensure that the antenna/lens are cleanable in accordance with the applicable approval.
1) Mounting in a pipe greater than 100 mm (4") can cause large errors, and therefore is not
recommended.
Suitable pipe diameters: Horn antenna 40 to 100 mm (1.5 to 4")
PVDF antenna 50 mm (2") only
Flanged encapsulated antenna 50 to 100 mm (2 to 4")
Hygienic encapsulated antenna 50 to 100 mm (2 to 4")

Entity concept:
The Entity Concept allows interconnection of intrinsically safe apparatus to associated apparatus
not specifically examined in such combination. The criteria for interconnection is that the voltage
and current which intrinsically safe apparatus can receive and remain intrinsically safe,
considering faults, must be equal to or greater than the output voltage (Uo) and output current
(Io) levels which can be delivered by the associated apparatus, considering faults and applicable
factors. In addition, the maximum unprotected capacitance (Ci) and Inductance (Li) of the
intrinsically safe apparatus, including interconnecting wiring, must be equal to or less than the
capacitance and inductance which can be safely connected to associated apparatus.
Under the entity evaluation concept, SITRANS LR250 has the following characteristics:
(input voltage) Ui = 24 V
(input current) Ii = 250 mA
(input power) Pi = 1.2 W
(internal capacitance) Ci = 0
(internal inductance) Li = 0

The FISCO Concept allows interconnection of intrinsically safe apparatus to associated
apparatus not specifically examined in such combination. The criteria for interconnection is that
the voltage (Ui or Vmax), the current (Ii, or Imax) and the power (Pi, or Pmax) which intrinsically
safe apparatus can receive and remain intrinsically safe, considering faults, must be equal to or
greater than the voltage (Uo or Voc or Vi), the current (lo or Isc or li), and the power (Po or
Pmax) levels which can be delivered by the associated apparatus, considering faults and
applicable factors. In addition, the maximum unprotected capacitance (Ci) and inductance (Li) of
each apparatus (other than the termination) connected to the fieldbus must be less than or equal
to 5 nF and 10 μH respectively.
In each segment only one active device, normally the associated apparatus, is allowed to
provide the necessary energy for the fieldbus system. The allowed voltage Uo (or Voc or Vt) of
the associated apparatus is limited to the range of 14V dc to 24V dc. All other equipment
connected to the bus cable has to be passive, meaning that they are not allowed to provide
energy to the system, except for a leakage current of 50 μA for each connected device.
Separately powered equipment needs a galvanic isolation to assure that the Intrinsically Safe
fieldbus circuit remains passive.
Under the FISCO evaluation concept, SITRANS LR250 has the following characteristics:
(input voltage) Ui = 17.5 V
(input current) Ii = 380 mA
(input power) Pi = 5.32 W
(internal capacitance) Ci = 0
(internal inductance) Li = 0

Special conditions for safe use (denoted by X after the certificate number)
● Parts of the enclosure may be non-conducting and may generate an ignition-capable level of
electrostatic charge under certain extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be subjected to external conditions (such
as high-pressure steam), which might cause a build-up of electrostatic charge on non-
conducting surfaces.
● Aluminium, magnesium, titanium or zirconium may be used at the accessible surface of the
equipment. In the event of rare incidents, ignition sources due to impact and friction sparks
could occur. This shall be considered when the SITRANS LR250 FF is being installed in
locations that specifically require Equipment Protection level Ga or Da.
● The equipment shall be infallibly bonded according to the relevant code of practice.
● The end use must ensure that the explosion protection and ingress protection of IP64 is

Functions in AMS Device Manager
Note
Do not use the handheld programmer at the same time as AMS Device Manager, or erratic
operation may result. To disable operation via the handheld programmer, see
Local
Operation (6.2.3.).
AMS Device Manager can be used to monitor the process values, alarms and status signals of
the device. It allows you to display, compare, adjust, verify, and simulate process device data.
Configuration and monitoring of the device is completed via parameters organized into three
main function groups:
● Configure/Setup
● Device Diagnostics (read only)
● Process Variables (read only)
Each function group is further divided into four blocks:
● Level Transducer Block (LTB)
● Liquid Crystal Display Block (LCD)
● Diagnostic Block (DIAG)
● Resource Block (RESOURCE)

Password Protection
7.1.18.1
User Manager utility
Usernames, passwords, and permissions, are assigned to users by an AMS Device Manager
administrator, using the User Manager utility on the Server Plus Station. Only a user with AMS
Device Manager System Administration rights can log in to User Manager.
To configure a new user/edit existing user:
1. From the Windows taskbar select:
Start > AMS Device Manager > User Manager
.
2. In the User Manager window click on
Add User
.
The Add User Wizard dialog allows you to:
● select a user type, standard (AMS Device Manager) or Window user.
● enter the username and password, and set permissions
● edit existing users
An AMS Device Manager administrator can configure the user to require a password. The use of
passwords is recommended. A password should be assigned to the ’admin’ username
immediately after installing AMS Device Manager.
Each user is given an AMS Device Manager username and password and required to enter
them when they start AMS Device Manager. Access to functions depends on the level of
permissions granted.
Login types
● standard, local, or domain
A standard user can change their password in AMS Device Manager. A Local or Domain
Windows user cannot change their password using AMS Device Manager and must request
their network administrator to do so.
