DF Data failure

If an error occurs in the Main microcomputer (PCB6) that prevents output of

geometry data to the TV set, the microcomputer will replace the missing data with

default data stored in the EPROM (6IC3) module 999.

POR1 Power on reset failure 1

Reset or update failure of module 999 during start up.

POR2 Power on reset failure 2

Reset or update failure of module 999 during start up.

PDD Power down detected failure

Power down failure detected on module 999.

CI Address conﬁguration impossible

Error during address conﬁguration. No address has been allocated because an

excessive number of units has been connected to the Master Link.

- Disconnect all units from the link and reconnect them again one at a time.

TD ML data pulled down

The link is pulled down (Low). This error can occur in the form of a physical short

circuit in the link. In the link drivers, or in the ML master/source circuit module 51

in the TV.

TU ML data pulled up

The link is pulled up (High). This error can occur in the form of a physical short

circuit in the link. In the link drivers, or in the ML master/source circuit module 51

in the TV.

TI Transmission impossible

It is not possible to send data to pin 8 on the V.TAPE or AV socket, probably because

of noise.

TD Data link tied down

The data link connection to pin 8 on the V.TAPE or AV socket is short circuited to

ground.

ST-01 Calibration error too few positions

Not enough positions are read during Stand calibration. The Stand may be blocked.

ST-02 Calibration error too many positions

Too many positions are read during Stand calibration.

ST-03 Calibration error EEPROM

Failure when the Stand offset should be stored in the EEPROM.

ST-04 Calibration error transducer

An invalid position is read from the transducer.

ST-05 Calibration error position

Several readings from the transducer with the Stand in the same position.
