Restart Pumping Program
The following is an automated dispensing Program for a NE-9000 peristaltic pump equipped with a
‘Syringe Filled Sensor’ attached to the TTL I/O connector, and a valve system to refill the syringe from a
reservoir. It is also assumed that the ‘Power Failure’ mode is enabled.
After a power fail restart, the pusher block is in an unknown position, making it impossible for an
automated dispensing system to regain synchronization. With the Syringe Filled Sensor, the following
Pumping Program will automatically synchronize the dispensing system, and then continue with the
normal dispense.
The first 2 Phases set an event trap for the Syringe Filled Sensor and refills the syringe until the sensor is
triggered. When the sensor triggers the event, the pump’s pusher block will be synchronized with the
Pumping Program. It is assumed that the sensor is positioned to refill the syringe with 60 ml. A withdraw
volume of 61 ml is set as a safety feature.
