Reciprocating and Dual Modes
Reciprocating Mode Dual Mode
Pumping Directions Pumping Directions
Syringes: Each pump can have a different size syringe, but make sure that the pumping rates on
the Master pump are within range of the syringe used on the Secondary pump. If an out-of-range
pumping rate is sent to the Secondary pump, the rate will just be ignored by the Secondary pump
without affecting the operation of the Master pump.
Master Pump: Pumping rate and direction are only transmitted to the Secondary pump from the
Master pump while the Master pump is pumping. If the Master pump starts or stops, the
Secondary pump will start or stop.
Reciprocating mode Sent to second pump: Rate and opposite pumping direction.
Dual mode Sent to second pump: Rate and current pumping direction.
Secondary Pump: Changes to the pumping rate and direction on the secondary pump will not be
transmitted to the Master pump. If the Secondary pump stops, the Master pump
will
also stop.
Pump Stall: If either pump stalls, then the other pump will also stop.
Synchronization between pumps: The secondary pump will lag approximately 30 milliseconds
behind the Master pump due to communications delay.
Reciprocating Pump Program
Below are examples of how to setup the pumps for reciprocating, continuous flow operation.
The Pump 1 program is the default program that is loaded as indicated in the "Default Program
Selection" section. Pump 1 is the Master pump which controls the Secondary pump's operation.
In Reciprocating mode, Pump 2 will pump continuously in the opposite direction of Pump 1, at
the same rate as Pump 1, and will change direction when Pump 1 changes direction.

Alternating Pumps Mode
Pump 2
Pump 1
Creates a semi-automated continuous infusion system using pre-loaded syringes. The infusing
pump will automatically start the alternate pump when the set volume is reached. The empty
syringe can then be manually replaced during the infusion of the alternate pump.
Alternate pump starts when first pump stops.
‘X Version Firmware Only (Enhanced features)
•
Delay Start of second pump.
Set the TTL setup setting: RUN.1
Delays start of alternate pump while executing a Pause Function. Alternate pump will start when
the Pumping Program has stopped.
•
Overlap pumping of the second pump.
Pumping Program Function: OUT.0
Immediately sends start to alternate pump when OUT.0 function is executed.
Allows the creation of an overlap between the infusing and the alternate pump to allow the
alternate pump to prime the syringe before the infusing pump stops.
If Phase 1 is set to function OUT.0, the alternate pump will immediately start when the Master
pump starts.
Overrides sending a start command when the infusing pump stops.
•
Stop Alternating Mode
Set TTL Trigger Mode to “Off”. When trigger is set to “Off”, start command will not be sent to
alternate pump.
Within a Pumping Program, the trigger mode can be changed with the Trigger function. This
allows a Pumping Program to limit the number of times that the alternate pump will execute its
Pumping Program.

The continuous pumping mode eliminates the problem of flow rate drop-off that
is typical with continuous syringe pump systems, where one pump is refilling the
syringe, while the other infuses, and then they switch directions.
In this system, the refilling pump refills at a faster rate than the infusing pump, giving it time to
prime the syringe, then it pauses and waits for the infusing pump to empty.
Then, when the pumps switch directions, the refilled pump is primed and starts infusing at the set
rate immediately. Additionally, an overlap can be set, whereby the refilled syringe begins
infusing before the infusing pump is completely empty.
Requirements
•
2 Pumps from the NE-1000X series of syringe pumps. Pumps can be different models.
•
1 Dual pump cable, part #CBL-DUAL-3.
Set communications mode to Continuous Mode [Cont]
On the Master Pump only: In setup, when the network address is displayed [Ad:00], or other
address mode, press the left-most up arrow key to select [COnt].
Note: Do not change the default settings on the second pump: Address 0 [Ad:00] and 19,200
baud rate [1920]. If unsure, reset the secondary pump: While turning on power, hold the leftmost up arrow button. The display will show [rESt].
Set Pumping Parameters on the Master Pump
Set syringe diameter and pumping parameters on the Master pump. The syringe diameter and
pumping parameters are transmitted to the second pump when the Master pump starts. Both
syringes start empty, unless pre-filled syringes are specified.

Set any optional parameter to 0.000 (off) if not used, or set the function to STOP. Pumping rates
not set will default to the Infusion Pumping Rate.
Hardware Setup
Attach the cable, CBL-DUAL-3, to the “To Computer” connector on the back of both pumps.
Operational Sequence
- Both syringes start empty. Set Phase 4, pre-filled mode, to use pre-filled syringes.
- Start the Master pump: Both pumps start filling, unless pre-filled syringes are specified.
- When syringes are filled:
•
Master pump starts infusing
•
Second pump primes (if enabled), then pauses
- When the infusing pump reaches the overlap position, if enabled, or changes pumping direction,
the paused pump will start to infuse
- Sequence repeats:
•
Refilling pump fills, primes, pausing and waits for the other pump.
•
Infusing pump infuses to the overlap position or syringe empty, and then signals the
other pump to start infusing. When empty, changes direction and starts refilling
While Pumping
The pumping rate can be changed. The new pumping rate will be transmitted to the other pump,
into the corresponding pumping sequence.
Pressing the Stop key on either pump, will Pause the sequence on both pumps. Pressing the Start
key, on the Master pump, will continue the pumping sequence.
Power Failure Mode – Auto-Synchronization
After a power failure restart, or to start the infusion with partially filled syringes, limit switches
can be attached to the pump at the refill position of the syringes. Attach the limit switch wires
between the Trigger Input (pin 2) and Ground (pin 9) on the pump’s 9 pin TTL connector.
Then enable Power Failure Mode in the Master pump’s setup menu.
When the pumps start, they will begin by filling the syringes until either the syringe volume
target is reached or the limit switch is triggered. Power Failure Mode overrides pre-filled syringe
mode settings.
Notes
The refill rate needs to be fast enough so that the syringe is refilled and primed before the
infusing pump has emptied.
If the refilling pump is still pumping when the infusing pump empties, an error message will be
displayed and the pumps will stop.
[Er:41] Error message indicates invalid pumping parameters.

Maintains a constant total flow rate between 2 syringe pumps. A gradient (linear function)
dispensing function is programmed into the Master pump. The secondary pump will be
automatically programmed with the inverse of the Master pump’s gradient function. The sum of
the two pump’s flow rates will be a constant. Both pumps will increase and decrease pumping
rates in tandem.

Set TTL setup setting RUN.0
- Continuous cycle: Ramp up, then ramp down, and repeat continuously.
Set TTL setup setting RUN.1
Requirement
1) 2 Pumps from the NE-1000 syringe pump series with ‘X firmware upgrades.
2) CBL-DUAL-3 dual pump communications cable.
:
Quick Setup:
On the Master pump only – DO NOT change default settings on the second pump.
1) Attach the communications cable, CBL-DUAL-3, to the “To Computer” port on the back of both
pumps.
2) Select the default Gradient Mode pumping program:
- Turn on power to the pump WHILE pressing the “Volume / Program Function” key.
- Use any up-arrow key to select Gradient Mode, displayed as:
- Press the key to select, or wait for the time out.
3) Set the syringe diameter on the Master pump. Both pumps will use the same diameter.
(Default program assumes at least a 14.43 mm diameter).
4) Press on the Master pump to start the dual pump Gradient pumping program.

Setup:
1) Attach the dual pump cable, CBL-DUAL-3, to the “To Computer” port on both pumps.
2) Select Gradient communications mode:
3) Set the syringe diameter.
4) Enter a Linear function pumping program as a 2 Phase Pumping Program:
Note: The secondary pump is set to the default communications settings of Address 0 and
19,200 baud rate.
On the Master pump only – DO NOT change default settings on the second pump.
From the Setup menu (Press and hold “Diameter / Setup” key), select Gradient
communications Mode (displayed as Grad). When Ad:00 (or other communications
mode) is displayed, use the left-most arrow key to select.
Phase 1: Linear function starting rate, and [hours:minutes] portion of pumping time.
Phase 2: Linear function ending rate, and [seconds:tenths] portion of pumping time.
Operation
When the Master pump is started, the Linear function will be expanded to a 5 Phase Pumping
program representing the forward and inverse of the linear function, then repeat. The second
pump will then be programmed with the syringe diameter and the inverse of the linear pumping
program. The Second pump will start pumping when the Master pump starts pumping.
With the starting and ending pumping rates reversed on the secondary pump, the sum of the flow
rates of the two pumps will be virtually constant.
Note:
The linear function updates the pumping rate every 100 ms, resulting in a synchronization
error of up to 100 ms between the two pumps. This will cause a slight difference in the total
volumes dispensed between the two pumps.
Default Gradient Pumping Program
To load the default program: On the Master pump, while turning on power, press and hold the
“Volume”/”Program Function” key until [Cont] is displayed, then use any up arrow key until
[GrAd] is displayed. Press the “Volume” key again to enter the selection.
