IntroductionThe Martel LC-110 and LC-110H are mA (loop) calibrators designed to be simple to use and to offer the highest accuracy of any loop calibrator in their class. The LC-110H differs from the standard LC-110 in that it incorporates HART communications and supports a select subset of the HART universal and common practice commands. This unique feature allows the LC-110H to be used as both a loop calibrator and basic function communicator.

The calibrator supports the following functions:

•Currentmeasurementandsourcing,includingselectable24Vsupply

•Voltagemeasurement

•Valvetestcapability

•SelectableHART250Ω loop resistor

•Outputstepandramp

The calibrator has the following features:

•Largeeasytoreaddisplayformeasurementsanddataentry

•Digitalknobwithselectabledecadecontrolforquickandeasydata entry

•Interactivemenus

•Inputandoutputjacksprotectedbyselfresettingfusesprovidingprotectionto240VAC

6.12 Error DisplaysThere are two classes of errors which may occur during HART communications. The first class contains errors that are reported by the loop device in its response. The second class contains errors that are detected by the LC110H when receiving responses from the loop device.

Loop Device Errors

These errors are reported by the loop device in its response to the LC110H,pertheHARTprotocol.

Theyareindicatedbythetext“LoopDeviceerror:”atthetopofthedisplay. This is followed by one of the following error messages.

1) Invalid selection

The data value sent with the HART command is not allowed by this loop device. The command was ignored by the loop device. HART responsecode2.

2) Value too large

The data value sent with the HART command is greater than the range allowed by this loop device. The command was ignored by the loop device. HART response code 3.

3) Value too small

The data value sent with the HART command is less than the range allowed by this loop device. The command was ignored by the loop device.HARTresponsecode4.

4) Message too short

The HART command received contains fewer characters than expectedbythisloopdevice.Thecommandwasignoredbytheloopdevice.HARTresponsecode5.

5) Device specific error

The loop device has detected a device specific error. The LC110H does not support the reporting of details on device specific errors. The command was ignored by the loop device. HART response code 6.

40

6) Write protected

The loop device is write protected. The LC110H can not alter the write protect status of a device. The command was ignored by the loopdevice.HARTresponsecode7.

7) Set to nearest possible value

The data value sent with the HART command was rounded or truncated due to limitations within the loop device. The command was accepted by the loop device. The resultant data values should bechecked.HARTresponsecode8.

8) Update in progress

The loop device is updating the data value on a delayed basis. The commandwasacceptedbytheloopdevice.HARTresponsecode8.

9) Incorrect loop mA mode or value

Theloopdeviceisnotinfixedcurrentmode,orthemAvaluesupplied is invalid. The command was ignored by the loop device. HART response code 9.

19) Access restricted

The HART command received is not allowed when the loop device in its current operating mode. The command was ignored by the loop device. HART response code 16.

20) Invalid units code

The units code received is not allowed by the loop device in its current operating mode. The command was ignored by the loop device.HARTresponsecode18.

21) Invalid span

The data values in the HART command would result in an invalid span for this loop device. The command was ignored by the loop device.HARTresponsecode29.

22) Busy

The loop device is temporarily busy performing some internal operation. The command was ignored by the loop device. Try the commandagainlater.HARTresponsecode32.

23) Command not implemented

The HART command has not been implemented in this loop device. The command was ignored by the loop device. HART response code64.

24) Character parity

The loop device detected a character parity error in one or more characters received. The command was ignored by the loop device. Trythecommandagain.Iftheerrorpersists,checkthepowerandconnectionstotheloopdevice.HARTresponsecode192(hexC0).

25) Character over run

The loop device detected a general communications error. The command was ignored by the loop device. Try the command again. Iftheerrorpersists,checkthepowerandconnectionstotheloopdevice.HARTresponsecode160(hexA0).

26) Character framing

The loop device detected a character framing error in one or more characters received. The command was ignored by the loop device. Trythecommandagain.Iftheerrorpersists,checkthepowerandconnectionstotheloopdevice.HARTresponsecode144(hex90).
