7) STALL DETECTION
The motor is monitored by an optical encoder to confirm the programmed movement.
If the back pressure increases due to jamming or flow restriction then the motor may
stall. Stall detection by the encoder results in a pump shutdown.
The display will read " Stalled ". The Stall message can be cleared with the Select key.
8) POWER DISRUPTION
When power is returned after a temporary power disruption the pump can be pro-
grammed to resume operation or remain stopped.
However, if a dispense volume is set then the pump always remains stopped.
9) NON-VOLATILE MEMORY
All operational settings are stored in non-volatile memory for convenience, and are
used to set the pump when first switched on.
10) SELECTION OF RATE AND VOLUME UNITS
Units of volume (µl or ml) and flowrate (µl/ml per min/hr) can be changed if required.
