Control unit Status Messages

Further operational alarm/error messages are shown on the LCD when any display parameter is selected. When either Readings or Diagnostic parameters (D200 - D265) are shown, the SMART Communicator is interrogating the MSM400 control unit every 0.5 seconds, and the information returned includes various message signals concerning the current status of the returned echo. These messages are displayed on the LCD line 2 for two seconds when the condition is first detected, instead of the Display parameter value. After this display period the condition message is abbreviated to a two letter code shown on the right hand side of the LCD, as long as the condition persists These status messages are updated every 10 seconds. Only one status message is displayed at a time, in a priority order, as listed below, to see all the alarms present use P520 - P525.

CURRENT SATURATED (CS)

The echo currently monitored is from a process value outside the pre-programmed 4-20mA range, so the current is either at 4mA or 20mA and is possibly not valid.

TEMPERATURE LIMIT (TL)

This indicates that the process temperature or a combination of the process and ambient temperatures have resulted in the electronics becoming too hot or too cold. Using the HHC, check P523 to see the maximum and minimum temperatures recorded. If the MSM400 electronics has recorded a temperature above 55°C then the electronics may have been permanently damaged. The MSM400 should be returned to Mobrey Measurement or your local agent for repair or replacement.

There are also various microprocessor fault messages which should be shown on the LCD, indicating significant problems with the sensor microprocessor. For all these error conditions reference should be made to the factory, and it will probably be necessary to return the unit for repair. The messages and codes are:

ROM CHECKSUM

RC

EEPROM SIGNATURE

ES

EEPROM CHECKSUM

EC

RAM TEST

RT

When an Unknown instrument is being interrogated, a universal set of error messages is used:

DEVICE MALFUNCTION

DV

PV OUT OF LIMITS

PL

NON PV OUT OF LIMITS

NL

CURRENT SATURATED

CS

D.10.2Invalid Data Entry

When the Operator tries to enter a command or parameter value which is invalid, the message on the screen will indicate this. Typical messages occur as follows:

“INVALID

INPUT”

(Rejected by the Psion Organiser)

“INVALID

DATA”

(Rejected by the MSM400 control unit)

-Parameter value entered is outside the limits allowed for that parameter, or resetting of this parameter is not allowed as per the data entered.

“IN WRITE PROTECT MODE”

- The Password is “Closed” or does not allow access to this parameter.

“INVALID PARAMETER NUMBER”

- Parameter number entered is not known by MSM400.
