1. ERROR TYPES

The HMP230 transmitters go through a self-diagnostics procedure when the

power is switched on. When the procedure does not reveal any errors or faults,

the transmitter starts operating normally. If errors or faults are found, the

transmitter outputs an error message. Possible errors can also be checked with

command ERRS (see Appendix 1).The error messages can be divided into two

groups: error messages after reset and error messages during operation. Note

also that if the analogue current output is selected to be 4 - 20 mA, in case of

error the signal drops to 0 mA.

1.1 Errors after reset

Display Serial bus

E11 CPU EEPROM ackn. error

- the CPU hybrid is probably damaged. Send the transmitter to Vaisala for

repair.

E12 CPU EEPROM checksum error

- possibly due to an electrical disturbance an erroneous parameter value or an

incorrect checksum has been stored in the EEPROM. Change any parameter

value (e.g. with command INTV) and give command RESET, or turn the

power off and then on again. If the error message no longer appears, the

transmitter is in order. Should the message re-appear repeatedly, send the

transmitter to Vaisala for repair.
