NE 1000 Syringe Pump Family Features

• Infuses and withdraws
• Selectable pump rate units: µl/hr, µl/min, ml/hr, ml/min.
• Change pumping rate and direction while pumping.
• Dispense a specified volume.
• Syringe purge mode will infuse or refill syringe at top speed to purge air from the line or to fill the syringe.
• Audible buzzer can be programmed to alert when an alarm condition occurs or the pumping program completes.
• Power failure mode restarts a pumping program interrupted by a power failure.
• Stall detection stops pump when the motor's operation is impeded (not on NE-500 model)
• Non-volatile memory restores all setup parameters and the pumping program, on power up.
• Elastomer raised keypad with optional beeping whenever the keypad is pressed.
• CE certified
• Worldwide Power Supplies available

• Pre-program a set of production dispensing protocols. The operator then selects the required dispense protocol
• Keypad Lockout: Prevent unauthorized or accidental changes to the settings by requiring a "Lockout Disable" key to be inserted to change settings.

• 41 programmable phases
• Enter programs from the keypad or from a computer.
• Download or upload pumping programs from or to a computer. Store dispensing programs in a file on your computer, then download them to one or more pumps. Specify in the file to send a different pumping program to each pump in the pump network.
• Pre-program dispense volumes. Each volume can be different.
• Automatically change pumping rates or pumping direction.
• Ramp up or down the pumping rate.
• Set timed delays between dispenses.
• Automatically pause the program and wait for the user to continue the dispense.
• Synchronize dispenses with other equipment or pumps to change pumping rates in reaction to a sensor or signals from other pumps.
• Send logic signals to other equipment. Change pumping rates in reaction to a sensor.
• Program the audible alarm to beep at any time to alert the operator.

• Network up to 100 pumps from a single communications port on a computer. Baud rates up to 19200.
• Free terminal emulator program allows communications with syringe pump.
• Directly control one or more pumps from a computer, including setting the pumping rate, direction and volume. Set the operational and setup configurations. Also the TTL interface can be queried and the programmable output set.
• Using a computer, each pump in the pump network can be individually controlled and monitored. Or, the computer can download a new pumping program to each pump which would automatically reconfigure the dispensing system for a new job.
• Downloading control programs to the pump would unload computer overhead to the pump. Computer resources could then be used elsewhere while the pumps operate independently.
• 2 modes of communications: Basic and Safe

• Basic: Basic master-slave interface. Easy to implement. Can communicate from any terminal emulator.
• Safe: A reliable interface for a real-world environment.
• - High quality interface which detects communication errors via a 16 bit CCITT CRC.
• - The pump will automatically transmit an alarm packet when a pump alarm occurs. For instance, if the pump stalls or resets, a message is immediately sent to the computer.
• - A configurable communications time-out will stop the pump and alarm if the communications link is broken.
• - Packet inter-character time-out to recover packet synchronization after communication glitches.

• Software Developer friendly communications protocol.

• Consistent and well defined communications packets.
• Constant start and end characters.
• Packets structured to be easily parsed

• Control the pump from a foot switch or timer.
• Output signals can be used to switch a valve from an output to an input reservoir.
• Keypad Lockout: Prevent unauthorized or accidental changes to the settings by requiring a "Lockout Disable" key to be inserted to change settings.
• Pumping direction control
• Programmable output signal
• Programmable responses to input signals
• Configurable start and stop trigger:
  • Start or stop the pump on each contact closure to ground. For example, a foot switch.
  • Start the pump on closure to ground and stop the pump on opening the connection. For example a timer relay that starts the pump whenever closed and stops the pump whenever open.
  • Only start the pump on each contact closure to ground. For example, a laboratory animal trained to press a lever can receive a drug dosage from the pump and the pump will not stop or deliver another dosage until it is permitted by the pumping program entered by the user
• Configurable trigger input:
  • Edge trigger: Starts or stops the pump, such as from a foot switch
  • Level trigger: Start or stops the pump, such as from a timer or relay control
  • Start only trigger: Edge trigger will only start the pump, such as from a lab animal trained to press a lever to receive a dosage.
