ESKII Remote Operation - HC 275 / AMS
Dev.-Rev. 01, DD-Rev. 01
1 General Information
The ESKII is a two-wire transmitter with 4..20mA current output and HART capability. It can be
mounted in H250 Variable Area Flowmeters with indicators M9 or M7. This document fills the gap
between the „Installation and operating instructions H250“ and the online help available under AMS.
General characteristics of the ESKII HART interface:
• Multidrop Mode is supported.
• Burst Mode is not supported.
• The ESKII transmitter implements a fixed optimized damping value on both the digital process
value transmitted via HART interface and the Analog Output.
2 HART Communicator 275 (HC275)
2.1 Installation
• Connection:
Refer to the wiring diagrams and descriptions in the
“Installation and Operating Instructions H250” (KROHNE) section 10.1.
• HC275 configuration:
The HC275 has to be programmed with the ESKII HART Device Description (DD).
Generally this must be done by the manufacturer or the distributor of the device.
(If the ESKII DD is not programmed in the HC275 the transmitter self test can’t be executed, the
Transmitter Specific Status Messages can’t be displayed and offline configuration is not
possible.)
2.2 Operating
See ESKII Menu Tree HC275 (Attachment A).
The ESKII operating concept bases on the HART DD for generic devices with the following
differences:
• Some parameters can only be read:
sensor units, range values (upper/lower range value), damping value, transfer function, write
protection, sensor units, final assembly number.
(For calibration of both the ESKII output information and the mechanical indicator of the
measuring instrument KROHNE offers a special program KroVaCal).
• Support of ESKII specific physical units
• Display format dependent on measuring range
• A ESKII Self Test can be performed and ESKII specific status messages can be displayed

• Meaning of General Status Messages:
Status Message Meaning
Field Device Malfunction Set if any „Critical Error“ has been reported.
Refer to Transmitter Specific Status messages.
Configuration Changed Set whenever any configuration parameter is changed.
Primary Variable Analog Output
Fixed
Analog Output Saturated During normal operation the maximum value for analog output
Primary Variable Out Of Limits Is set whenever the Process Value (PV) exceeds the Sensor
Set when:
• Device is set in Multidrop Mode
(Polling Address ≠ 0)
• Fixed Current Mode is entered
(during Loop Test and DAC Trim)
is 20.4mA because of the „Namur Failure Signal“ (I>20.8mA).
While Process Value (PV) will work up to the Sensor Limits
the analog output and its digital value is saturated at 20.4mA
and the flag is set.
Limits.
• Meaning of Transmitter Specific Status Messages:
Status Message Meaning
Critical Error Error: Summary of „Initialization Failed“ and „Internal Checksum
Error“. If set the measurement is invalid.
HART-Classes: Hardware, State, Uncorrectable, Summary.
Initialization Failed Error: If set the measurement is invalid.
HART-Classes: Hardware, State, Uncorrectable, Detail.
No Linearization Data Warning: If set the measured value is possibly incorrect.
HART-Classes: Software, State, Uncorrectable.
Internal Checksum Error Error: If set the measurement is invalid.
HART-Classes: Software, Event, Selfcorrecting/Uncorrectable,
Detail.
Internal Timeout Informational: Self correcting error.
HART-Classes: Software, Event, Selfcorrecting.
ADC zero scale not calibrated Warning: If set the measured value is possibly incorrect.
HART-Classes: Hardware, State, Uncorrectable.
ADC full scale not calibrated Warning: If set the measured value is possibly incorrect.
HART-Classes: Hardware, State, Uncorrectable.
No TC correction data Warning: If set the measured value is possibly incorrect.
HART-Classes: Software, State, Uncorrectable.

3 Asset Management Solutions (AMS)
3.1 Installation
• Connection:
Refer to the wiring diagrams and descriptions in the
“Installation and Operating Instructions H250” (KROHNE) section 10.1.
Also see the
“AMS Installation Guide” (Fisher Rosemount) section 5: “Installing Modems” and
appendix B: “Wiring Diagrams”.
• AMS Configuration:
If the ESKII Device Description is not already installed on the AMS System a
„ESKII Device Installation Kit“ (on floppy disk / CD-ROM from KROHNE) is needed.
For installing the DD with the Installation Kit refer to the
“AMS Installation Guide” (Fisher Rosemount) section 3:
“Installing Device Descriptions for Field Devices”, “Manually Installing Device Types”.
3.2 Operating
See ESKII Menu Tree AMS (Attachment B).
The operating concept bases on the AMS HART DD for generic devices. For differences in detail
see section 2.2 HART Communicator 275 (HC275) Operating.
