SP1600/1800 Programmable Syringe Pump
Publication #1200-02 12 9/15/04
A communications time-out alarm occurred with an attached computer while operating in
the “Safe Communications Mode”. This most likely indicates that the RS-232 cable was
detached or the communication program on the computer has ended without turning off
“Safe Communications Mode”.
n
An error was detected during power up, where ‘n’ indicates the error. If n=1, then the
values stored in the pump’s non-volatile memory were invalid and were reset. If n=2,
then the non-volatile memory may need to be replaced.
Pump settings are locked out from the keypad. The lock out key is needed to change
settings. Lock out can also be reset with the reset function.
