ERROR MESSAGES
The EDI-53 indicator displays a number of appropriate error messages whenever it encounters a
hardware fault, an invalid calculation, or a wrong entry etc.
As the display can show a maximum of 16 characters at a time most of the error messages directly
announce the error without explicitly showing the word ‘Error’.
The various ‘Error’ messages are listed below in alphabetical order. Most of these error messages are
flashed for approximately one to two seconds on the display. For those messages which are not
automatically cleared you will have to press the ‘ESC’ key to clear the message.
* EXIT ! *
This is not exactly an error message. This prompt only informs you that you have chosen to ‘Cancel’ the
current operation, say by pressing the ‘ESC’ key, and the indicator has not fully executed the command
you were trying to execute.
Err: ADC FAULT
The internal ADC or the associated circuit used for voltage measurement has probably developed some
fault. You will need to get the indicator checked by a qualified service engineer or return the unit back to
Encardio rite to remove the fault.
Err: MEMORY FULL
You are trying to store a reading in the data memory and the data memory is already full. That is, all the
6700 locations have stored data. You should either print out the logged data or transfer the logged data
to a computer and run ‘Clear data memory’ function to be able to reuse this memory for storing further
data.
Err: NVRAM FAILED
This error message appears only during Power On Self Test.
The ‘Setup’ and ‘Logged data’ are stored in an internal Non-Volatile Random Access Memory (NVRAM).
The information stored in an NVRAM remains as intact even if the indicator is turned off. However if there
is a hardware fault or the NVRAM module becomes faulty, the stored information gets corrupted. In such
cases the indicator will detect the fault during power on self test and output the above message.
If you get this error the indicator will need servicing by a qualified technician.
Err: OUT OF RANGE
The value you just entered is beyond the acceptable limits for that parameter which you are modifying.
Check the value which you had entered and re-enter the correct value.
INVALID INPUT
The indicator is not expecting the key pressing or the value which you just entered. Check the reason
and press the correct keys.
NO Ch SELECTED
You are trying to switch over to the ‘UNITS’ mode for engineering units display without specifying which
channel number data to use. First select the channel number associated with that transducer by pressing
the ‘CH NO’ key then select the ‘UNITS’ mode.
NO TXDR SETUP
You are trying to select a channel number for engineering units display which has not yet been setup with
any valid transducer coefficients. First you should setup the channel by entering the calibration
