press enter
This screen indicates corruption of the RAM or that the EPROM has been changed. In either
case pressing Enter will re-initialise the RAM and clear the error.
check drive and
setup now
This screen indicates that the motor has stalled or that a loss of tachometer pulses has
been selected. Clear the cause of stalling and power the pump off and on. If the error
persists seek qualified assistance.
Rs232 parameter
error
Signifies an illegal command string when under RS232 control.
data corrupted!
recalibrate
A corruption of data has been detected. Switch unit off and on. Re-calibrate using Head
and Tubing first followed by a calibration dose if necessary.

Flow rates
Flow rates for the 624Di/R and 624Di/L were obtained pumping water at 20C with
negligible suction and delivery pressures (unless otherwise stated). Where an application is
critical, the flow rate should be determined under operating conditions. The important
factors are suction and delivery pressures, temperature and fluid viscosity.

Note: Flow rates quoted have been rounded for simplicity, but are accurate to within 5% -
well within the normal tubing tolerance variation of flow rate. They should therefore be
