ERROR MESSAGES
Symptom: Screen shows error instead of data.
Reason: If no data is received from the sensor, the screen will show ‘ERROR’.
Fix: Check the LEDs are ashing in the Electronic unit. LD 100, LD 200.
• Connect a PC to the RS-232 Diagnostics Sensor/‘HEAD’ connector in the
electronic unit. If the system is sending $PSKP.....ERRBOR or similar, the
voltage to the sensor is too low.
• Check if the Voltage on J200 p1 p2 is 18-25 V.
• Check if the voltage in junction box is >15 V, if not, twin pairs to get higher
voltage. (If yellow/orange pair is not required and can be disconnected and
used to parallel the power).
• If no, or garbled data, check that the pairs are connected correctly (A/B).
If you suspect you have a problem within the CD401 unit, an error message table
can be retrieved from the unit by sending the message $PSKPCPPCERROR
<CR><LF> from the ‘compact’ connector of the JB60CD or the NMEA input on
repeater. The returned format is in the form: ID, number of errors, last error, rst
18 errors.
$ PSKPERRORTABLE,19,32,100,<Error18>,…,<Error1>
< Identier >,<Number of errors(19)>,<Last Error after 18 errors(32)>,<rst 18
error>,
This format shows a table of 20 numbers, where position 1 shows the number
of errors stored. The errors are stored on the ash memory and will be retained.
If you suspect an error, download the messages, then reset the error messages
and try to perform the same error condition again. If successful, download the
errors again and then check the list below. In addition, the self test values 0-4
can be used to check the main peripherals of the unit.
