When the low pressure trap is triggered, the pump sets the high pressure trap (PHASE 07) and begins to
increment the flow rate. The flow rate is incremented in 1.0 mL/hr steps with every 0.25 mL dispensed
(PHASE 08-10). If the high pressure trap hasn’t as yet been triggered, the flow rate will max out at 25.0 mL/hr
while waiting for the high pressure trap (PHASE 11). When the high pressure point is reached, the pump
immediately will drop down to 10.0 mL/hr (PHASE 02), and once again wait for the low pressure point.

Restart Pumping Program
The following is an automated dispensing Program for a NE-500/501 syringe 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 a Syringe Filled Sensor, the following Pumping Program
will automatically synchronize the dispensing system, and then continue with the normal dispense.
