Error messages relating to data transmission:
Note:
If neither a printer nor a computer is connected the report output
must be switched off.
General form of error message:
* * * RS er r or xx
Error during data transfer or printing. Check whether the connection
cable has been attached correctly and that the RS232 parameters of
the transmitting and receiving instruments are the same. See
<CONFIG>, >RS232 settings
Reception errors:
* * * RS er r or 36
Parity error
Exit: <QUIT> and set the same parameter on both instruments.
* * * RS er r or 37
Framing error. The receiving instrument may not be ready to receive
data. Exit: <QUIT> or switch Liquino off and on. Check settings of
receiving instrument.
* * * RS er r or 38
Overrun error. At least 1 character could not be read.
Exit: <QUIT>.
* * * RS er r or 39
The internal processing buffer in the Liquino is overloaded (>128
characters). Exit: <QUIT>.
Transmission errors:
* * * RS er r or 42
CTS=OFF. Handshake not satisfied for more than 1 s.
Exit: <QUIT>. Is the receiver switched on and ready to receive?
* * * RS er r or 43
The Liquino transmission has been interrupted by XOFF for at least 6
s. Exit: <QUIT>.
* * * RS er r or 45
The receive buffer of the Liquino contains an incomplete character
string (L
F
is missing). The Liquino transmission is therefore blocked.
Exit: send L
F
or <QUIT>.
Warnings
* * * Dosi ng not cont i nuous. Lower r at e * * *
You have defined a dosing rate which is too high for tandem dosing. Inter-
ruption-free dosing is not possible as a filling process (including stopcock
switching) takes longer than dosing a cylinder volume. Press <HOLD> and
reduce the dosing rate to 85% at the most of the maximum possible dosing
rate for the dosing unit. Dosing can then be continued with
<HOLD/CONTINUE>.
* * * Rat e t o hi gh. Adj ust par amet er ! * * *
The necessary dosing rate required to fulfill the task you have defined can-
not be reached. Press <HOLD> and reduce the volume to be dosed in or
extend the dosing period. Dosing can then be continued with
<HOLD/CONTINUE>. If you do not correct the parameters dosing will be
carried out at the highest possible dosing rate. However, the defined dosing
time cannot be observed in this case.
