Operating instructions
General
This section describes display and function key operation for AST 3P
in normal Operating mode.
Power supply
Power supply to the signal transmitter should not be turned off during week-ends
and over-night. Continuous power supply to electronics and transducers prevents
moisture condensation in the units.
Start-up
As soon as power is connected to the instrument, start-up is performed.
The text ‘AST 3’, the programme name and the serial number of the module
are displayed for about five seconds.
Then AST 3P is automatically switched over in Operation mode.
(If the instrument is set for operator start-up, the text
‘Press ENTER to start AST’ is displayed until the key to the right
is pressed and the instrument enters Operating mode.)
If an error occurs the start-up stops and an error message is displayed.
Error codes and error corrections are described in section 7. Troubleshooting in
the Technical Manual for AST 3.
As AST 3 is in Operating mode, a view with the weight value and the instrument
address is displayed.
For the internal relays in use, the status is displayed (R1/R2: On or Off).
