Tubing Calibration

Calibration mode fine tunes the dispense accuracy. Continued use of tubing will cause it to stretch and deform which creates dispensing errors. Also, differing viscosities and/or pumping speeds can also affect pumping accuracy.

Calibration uses the currently selected dispense program. Also, you will need a calibrated measuring cup to verify the actual dispense volume.

To begin calibration: While turning on power, press and hold the ‘LEARN’ key until the display shows:

Press any up arrow key for the next Learn selection: Calibration:

Press the ‘Start’ key to begin the dispense.

When the dispense is complete, the pump will stop, and the dispensed volume will be displayed with the volume units LED blinking.

Press the ‘LEARN’ key to accept this volume, or use the up arrow keys to enter a measured dispense volume.

Press ‘LEARN’ after the measured dispense volume has been entered and to store in memory.

The pump is now calibrated. Dispense volumes and pumping rates will be adjusted according to the measured volume entered.

Tubing Inside Diameter Setting

For most applications, the default tubing inside diameter does not need to be changed since the standard pumping head is optimized for 3/16” inside diameter (ID) tubing.

If needed, to change the tubing diameter setting, enter Diameter Setting mode: While turning on power, press and hold the ‘Diameter’ key until the display shows:

Press the ‘DIAMETER’ key again to select. The display will show the current diameter and the ‘Inches’ units LED will blink. While the units LED is blinking, use the up arrow keys to enter the new diameter as a fraction of an inch. For example, to enter 1/16” id tubing, use the up arrow keys to change the display

to:

Press the ‘LEARN’ key, or wait for the time out to enter the new setting. The tubing diameter will now be set to the new setting. The new diameter will be used as the current calibration setting.

Special Modes

Press and hold the ‘Diameter’/’Setup’ key to access the Special Modes setup menu The first mode, “Slow-Down” will be displayed:

Press the ’LEARN’ key to move to the next mode, or wait for the time out. The following is the sequence of diplays:

Anti-Drip Mode

Setting: ‘0’ = Disabled, ‘1’ = Enabled.

When enabled, Anti-Drip mode will withdraw a small volume after the completion of a dispense to prevent dripping or oozing when the pump stops. The volume withdrawn is added to the next dispense.

Dispense, Pause, Repeat Mode

Setting: ‘0’ = Disabled, ‘1’ = Enabled.

When enabled, will create a more automated dispensing system, whereby the pump will continuously repeat the current dispense after a fixed time delay. The time delay will be displayed next:

Where ‘nn’ is the pause time in seconds. Use the arrow keys to change the dispense time.

By understanding the key concepts and terminology used in this manual, the operation of the NE9000 will become quite intuitive. Every effort has been made to design the NE-9000 with a consistent and intuitive user interface.

♦ Two modes of RS-232 computer control, Basic

and Safe. Safe mode provides communication error detection, loss of communication detection, and automatic transmitting of alarm conditions.

♦ TTL I/O with firmware filtered control inputs to

eliminate glitches and ringing on the control inputs.

♦ Configurable TTL operational trigger.

♦ Power Failure Mode: Restarts the Pumping

Program after a power interruption.

♦ Audible Alarm.

♦ Many more features

To facilitate and enhance your understanding of the NE-9000’s operation, please take the time to familiarize yourself with the basic concepts below:

When the pump is started with the ‘Start’/’Stop’ key, or any other source, the pump begins performing the operations in the Pumping Program until the Pumping Program either stops automatically or the pumped is stopped when the ‘Start/Stop’ key is pressed, or from any other source. While performing the operations defined in the Pumping Program, the Pumping Program is referred to as operating.

While Operating, the motor can be pumping or stopped, according to the Pumping Program.

The motor is stopped and the pump is not operating the Pumping Program.

The Pumping Program has been stopped, but can be resumed at the point where it was stopped.

Continuing a Pumping Program that was Paused before the completion of the Pumping Program. The Pumping Program continues at the point where the Pumping Program was stopped.

The pump has performed a single operational Phase as defined in the Pumping Program.

unction:

Setup

A single defined operation in the Pumping Program.

A Program Phase’s numerical sequence location in the Pumping Program.

Each Pumping Program Phase instructs the pump to perform a particular operation. Only one Program Phase is selected at any one time. This is the current Phase. Each Phase is set to one function. The set function of the current Phase is the currently selected function.

Each Pumping Program function instructs the pump to perform a particular operation. If the Phase’s operation instructs the NE-9000 to pump, then associated with that Phase is the Phases’ pumping information. When ‘Program Entry Mode’ is exited, the ‘Rate’, ‘Volume’, and pumping direction keys refer to the currently selected Program Phase’s function. The Program functions that are associated with pumping information are referred to as Pumping Rate functions.

Certain functions, which do not instruct the NE-9000 to pump, require additional data. This additional data, displayed with the function, is the function’s parameter.

The Pumping Program may be started, or stopped, from multiple sources. These are the keypad’s ‘Start’/’Stop’ key, the TTL I/O ‘Operational Trigger’ input, or from a command received through the RS-232 connection.

♦ Place the pump on a stable surface.

♦ Plug the round connector end of the supplied power supply adapter into the power plug located on the

lower right of the pump's rear. See section 13, Logic Interface: TTL Input and Output, for a diagram of the rear of the pump. Plug the other end of the power supply adapter into an appropriate electrical outlet. The pump will be powered when the bottom of the power switch, located on the upper right of the rear of the pump, labeled ‘1’, is pressed. The red indicator on the switch is visible when the power switch is in the ‘on’ position. After power is applied to the pump, the pump’s display will flash.

♦ Next the Pumping Program can be entered. Before the Pumping Program can be operated, the pump

needs the measurement of the peristaltic tube inside diameter. The peristaltic tube inside diameter can be entered using the keypad. Refer to ‘Diameter’ and ‘Setup’ Key. The default setting is 3/16” tubing

Publication #1200-04 5

Entering Values

When applicable, values can be changed by either displaying the current value, then using the arrow keys, or from a computer connected to the pump. The new value will be stored in the pump’s non-volatile memory, meaning that the new value will not be lost the next time that power is applied to the pump. The only exception is when the pumping rate is changed from an attached computer while the Pumping Program is operating. In this case the new pumping rate will not be stored in non-volatile memory.

A displayed value can be changed by pressing the arrow keys below each digit. If the value to be changed is not currently displayed, when applicable, press the key associated with the required value. The display will show the setting’s current value and its units, if any.

While the current value is being changed, the units LEDs associated with the value, if any, will blink. Except where noted, the new value is stored, and/or the selected operation takes effect, when either

Arrow and Decimal Point Keys

Each of the four digits in the display is associated with the up arrow key directly below it. When applicable, the arrow key is used to increment the value of that digit, or advance to the next selection in a list of functions or settings.

Each press of an up arrow key will increase the digit by 1, up to 9, and then back to 0. The arrow keys may also be held down for continuous incrementing of numbers. Some parameters, such as the RS-232 baud rate, scroll through a selection of values when the arrow keys are pressed. Other parameters have a fixed range of values, such as some setup parameters that are either turned on or off. In these cases, the arrow key will only scroll up to the maximum value for that parameter, then back to the minimum value.

When changing the pumping rate units, each press of any arrow key will change the units LEDs to the next units selection.

When the display blinks, the new value is stored and takes effect. This will occur when a non-arrow key is pressed or after a 2 second delay since the last key press.

Operating the Pump

When the “Start/Stop” key is pressed, the Pumping Program begins to operate. In Dispense Mode, the currently selected dispense will begin. If Dispense mode is off, the Pumping Program will begin, starting with Phase 1. If the current Program Phase specifies a pumping rate, the pump will begin pumping, and the ‘Pumping’ LED will be lit.

The pumping direction will depend on the selected direction. The display will show the “Volume Dispensed” with a volume units LED (‘mL’ or ‘Oz’) and the ‘Dispensed’ LED lit.

While pumping, the pump will pump continuously in the current Program Phase, unless a “Volume to be Dispensed” is set, or an Event trigger is set. If a “Volume to be Dispensed” is set, the Program Phase will be complete after the set volume has been dispensed or withdrawn, measured from the start of the Phase.

Pressing the ‘Volume’ or ‘Diameter’ keys will display the current “Volume to be Dispensed” or the diameter setting while the key is held.

Changing the Pumping Rate and Direction While Pumping

Except with some complex Pumping Programs, the pumping rate can be changed while the pump is operating. To change the pumping rate, momentarily press the ‘Rate’ key. While the pumping rate is displayed, press the up arrow keys to change the rate. The rate units will blink while the rate is being changed. If the up arrow keys are not pressed, the display will return to the “Volume Dispensed” display after a 2 second delay. Rate units cannot be changed while pumping.

The new rate is stored after a 2 second delay or by pressing a non-arrow key. If the new rate is within the operating range of the pump, the display will blink and the new rate will be stored in the current Program Phase and the pump begins pumping at the new rate. If the new rate is out of the operating range of the

pump, the display will show

The pumping direction can be changed while pumping if the “Volume to be Dispensed” is 0.0 (off). Pressing the direction key will immediately change the pumping direction and store the pumping direction in the current Program Phase. Also changing the pumping direction changes the accumulated “Volume Dispensed” according to the new pumping direction.

7.7

Volume Dispensed

While pumping, the display will show the total accumulated volume pumped with the ‘mL’ or ‘Oz’ LED lit and the ‘Dispensed’ LED lit. Volume is computed based upon the inside diameter setting.

The volume is accumulated separately for dispense and withdrawal. When the pump changes direction, the “Volume Dispensed” changes to the accumulated volume for the current pumping direction.

The “Volume Dispensed” accumulations, for dispense and withdrawal, are reset to 0 when:

. Pressing any key clears the error message.

A) Pressing and holding any arrow key while displaying the “Volume Dispensed”.

B) A sub-program is selected when the Pumping Program executes a Program Selection

function.

C) The diameter is changed.

F) The pump is powered on.

When the Pumping Program is stopped, and the display shows the Program function or pumping rate information, the accumulated Volume Dispensed can be displayed by pressing the ‘Volume’ key one, two, or three times, depending on the current display.

7.8

Resuming When Paused

If the Pumping Program is stopped before the completion of the Pumping Program, the ‘Pumping’ LED will blink, indicating that the Pumping Program is paused. While the ‘Pumping’ LED is blinking, starting the pump again will resume the Pumping Program where it was stopped. This means that the Pumping Program will continue at the point in the Phase where it was stopped and the ‘Volume to be Dispensed’ will still be referenced from when the Program Phase first started.

Pressing any key other than the ‘Start’ key will cancel “Pumping Program paused” and the ‘Pumping’ LED will stop blinking. When the Pumping Program is started again, it will start from the beginning (Phase 1).

Learn and Repeat

“Learn and Repeat” easily teaches the pump a dispense volume. Then you can immediately repeat this dispense. Dispense Mode must be set to repeat a dispense.

While turning on power, press and hold the ‘LEARN’ key. The display will show:

Press the ‘LEARN’ key, or wait for the time out, to immediately store the dispensed volume in the currently selected dispense setting. A double beep will sound and the display will show:

Press any key to return to the currently selected dispense program display. Press ‘Start’ to immediately begin the newly learned dispensed.

A Pumping Program is simply a pre-defined sequence of actions, or functions, which guarantees consistent and precise operation of the pump, automatically, and with or without any user intervention. A Pumping Program can be as simple as continuous pumping at a fixed dispense rate. Or a Pumping Programs could consist of a pumping rate and direction of pumping for a specified volume, then switch to another pumping rate. Also a Program can interact with external devices through the TTL I/O connector, make decisions, or stop pumping for a period of time.

Programs are broken into individual operations called Phases. Each Phase consists of a function that can be a control function or pumping function. A pumping function, such as ‘RATE’, consists of a pumping rate, optional “Volume to be Dispensed”, and the pumping direction.

Complex dispensing systems can be designed, involving multiple liquids, each dispensed from a different pump, plus other equipment and sensors. Pumping Programs can be designed for each pump which enables multiple pumps to synchronize with each other, and the other equipment and sensors, using a cable connected to the TTL I/O connectors of each pump.

When the Pumping Program is started, either from the keypad, TTL I/O connector, or from RS-232, the Pumping Program will begin with Phase 1 of the Program. After the completion of each Phase, the pump will immediately start the next consecutive Phase. This linear sequence of Phases can be altered by certain functions that direct the Pumping Program to continue operation with a different Phase number. Some functions can change the order of operation conditionally based on external events.

11.1

Note: Dispense Mode needs to be off to enter a Pumping Program. Start by organizing your pumping requirements into specific actions and conditions that can then be programmed into Phases. For more advance programming methods, common groups of Phases can be grouped together and repeated multiple times using looping and jump functions.

The current values of the pumping rate, optional “Volume to be Dispensed”, and pumping direction, all refer to the currently selected Phase. To display or change the currently selected Phase, enter “Program

Entry Mode” by pressing and holding the ‘Rate’/’Program Phase #’ key until the current Phase number is

displayed. The display will show , where ‘01’ refers to Phase 1. The pump will now be in “Program Entry Mode”. If the current Phase is not 1, press and hold the ‘Rate’/’Program Phase #’ key until the display is as shown. The pump will now be in Phase 1.

When in “Program Entry Mode”, with the display showing the Program Phase number, pressing the ‘Volume’/’Program Function’ key will display the current “Program Function” for this Phase. If the current function is ‘RATE’, then a pumping dispense or withdrawal can be setup for this Phase.

To change the “Program Function” selected, use the arrow keys to scroll through the functions until the required function is displayed. If the function has an associated parameter, enter the parameter after the function has been stored.

Momentarily pressing the ‘Volume’/’Program Function’ key again will exit “Program Entry Mode” and display the “Volume to be Dispensed.” The pumping rate data, which includes the pumping rate, “Volume to be Dispensed” and pumping direction, can now be setup as previously described.

When finished setting up the pumping rate data for the current Phase, enter “Program Entry Mode” again to select the next Program Phase. Press and hold the ‘Rate’/’Program Phase #’ key until the Phase number is displayed. Then use the arrow keys to set the Phase number to the next Phase to be setup. Pressing the right-most arrow once will set the Phase to Phase 2. Now all pumping data will refer to Phase 2. The second Phase can now be setup as described above for Phase 1.

Continue selecting Phase numbers and entering the dispense or control setup for each Phase of the Pumping Program. The entire Pumping Program will be stored in non-volatile memory.

www.SyringePump.com

Model NE-9000

Use the ‘STOP’ function to stop the pump and end the Pumping Program. If the Pumping Program does not operate the pump continuously, the last Phase of the Pumping Program must be a ‘STOP’ function (unless the last Phase number is the maximum Phase number).

When the Pumping Program is started, with the ‘Start / Stop’ key, TTL I/O input, or RS-232 command, the Pumping Program will begin operating from Phase 1.

Very complex dispensing Programs can be created with the Program functions available. Section 11.3 contains a detailed description of all the functions.

11.1.1 Pumping Program Phase Number

To set the current Program Phase number, enter “Program Entry Mode” and display the current Program Phase number.

Using the right-most 2 arrow keys, change the selected Program Phase number. The displayed Program Phase number now becomes the currently selected Program Phase number. All function and pumping rate data will now refer to the currently selected Program Phase number.

If the maximum Program Phase number, 40, is exceeded while changing the Phase number, the displayed Phase number will automatically be set to the maximum Program Phase number.

11.2

When developing or updating a large Pumping Program, occasionally one or more Program Phases needs to be added or removed from the Pumping Program. Having to re-enter the entire Program could certainly be a tedious task.

Pumping Program Edit Functions

Two Program entry functions are available to simplify the Program development process. These are the ‘Insert’ and ‘Delete’ functions. They allow a Program Phase to be removed from any point in the Pumping Program or a Phase to be inserted at any point.

To access these functions, enter “Program Entry Mode” to display the Program Phase number [PH:nn]. Select the Program Phase number that is to be deleted or the Phase number where a new Phase is to be inserted in the Pumping Program.

For example, if a Phase is to be inserted between Phases 24 and 25, select Phase 25. The inserted Phase will be at Phase 25, and all the Phases starting with the old Phase 25 will be shifted one Phase higher.

Publication #1200-04 25

Page 34

New Era Pump Systems Inc.

Using either of the 2 left-most arrow keys, under ‘PH’ in the display, select the editing function. The arrow keys will scroll through the selection of editing functions:

When the required editing function is displayed, press the ‘Rate’/’Program Phase #’ key before the 2 second time out. After the time out, or with any other key press, the function will be canceled.

If ‘Insert’ or ‘Delete’ was selected, the Pumping Program will be edited. While the Program is being edited, the display will show [BUSY].

If ‘Insert’ was selected, all Phases from the selected Phase to the maximum Phase will be moved to the next higher Phase, with the original maximum Phase being deleted. The inserted Phase will default to a ‘RATE’ function, if it is the first Phase, or a ‘STOP’ function otherwise.

If ‘Delete’ was selected, the selected Phase will be removed, and all Phases higher then the selected Phase, up to the maximum Phase, will be moved to the next lower Phase.

All Phases that reference the Phase number of another Phase, such as a ‘jump’ function or an ‘event’ function, will be automatically updated. The referenced Phase numbers will be automatically adjusted to compensate for the section of the Pumping Program that was shifted during the operation of the edit function.

Ultimately, the easiest method to maintain and develop Pumping Programs is to download the Pumping Program to the pump from an attached computer. This would allow a single Pumping Program to be quickly programmed into multiple pumps. The computer would only need to be attached during the download since the Pumping Program is stored in the pump’s non-volatile memory.

Program Function Descriptions

11.3.1 ‘rAtE’: Rate Function

Defines a pumping function with a fixed pumping rate. This function defines a pumping setup consisting of the pumping rate, optional “Volume to be Dispensed”, and pumping direction. Use the ‘Rate’, ‘Volume’, and ‘Pumping Direction’ keys to set or review the pumping setup. For continuous pumping, set the “Volume to be Dispensed” to 0.0 (off). The “Volume to be Delivered” is disabled when the display reads [ off].

11.3.2 ‘InCr’: Increment Rate Function

The increment and decrement functions operate the same as the ‘RATE’ function, except that the specified rate is added (‘INCR’) or subtracted (‘DECR’) from the current pumping rate. The current pumping rate when the function is executed is the base pumping rate for the function. If no base pumping rate exists, such as when executing a pause function or when the Pumping Program is first started, a Program error will occur and the Program will stop.

The pumping rate units will be the same as the base pumping rate, and therefore cannot be set, nor are they displayed, with the pumping rate increment or decrement value. As with the ‘RATE’ function, a “Volume to be Dispensed” and pumping direction can be specified for the increment and decrement functions.

When used within a Program loop, the pumping rate can be incremented or decremented in small step intervals.

11.3.3 ‘DECr’: Decrement Rate Function

The decrement function subtracts the specified rate from the current pumping rate. For a full description, see section 11.3.2, ‘InCr’: Increment Rate Function

11.3.4 ‘StoP’: Stop Pumping Operation and End the Program

Stops the pumping operation and stops the Pumping Program. The Pumping Program will begin at Phase 1 when started again. An implicit ‘Stop’ function is executed when the Program exceeds the maximum Phase number during operation.

If alarms are enabled, the buzzer will beep continuously when the Pumping Program stops.

11.3.5 ‘JP:nn’: Jump to Phase

The ‘Jump’ function alters the consecutive operation of Program Phases. When executed, the Pumping Program will continue operation with Phase ‘nn’.

11.3.6 'Pr:In': Program Selection Input

The Pumping Program can be broken into sub-programs which can be selected by the user.

Auto-Run Production Mode: When Phase 1 is set to Program Selection Input, and Lockout Mode is selected, the pump will enter Auto-Run Mode. When the pump is powered on, it will immediately begin executing the Pumping Program. The user will immediately be prompted to enter a sub-program number. This permits a set of production dispenses to be programmed into the pump. The user then would only be able to select from one of these production dispenses and not make any changes.

Foot Switch Trigger Feature: If the Pumping Program was Paused, and the Paused Phase was a continuous pumping Rate function, then starting the pump with a foot switch will cancel the Pause and restart the Pumping Program Phase 1 causing the current program selection to be re-executed.

When the Program Selection Input function is executed, the Pumping Program pauses and

displays:

Using the right 2 arrow keys, under 'nn', the user enters the Label of the required Pumping Program. The Pumping Program Label is defined by any number from 1 to 99. When the 'Start' key is pressed, the Pumping Program continues execution at the Program Phase with the selected Pumping Program Selection Label. Also, the accumulated dispense and withdrawal dispensed volumes are set to zero.

The pump searches for the selected Pumping Program Selection Label starting with the current Phase and continuing to the end of the Pumping Program memory, then from Phase 1 until the current Phase is

reached again. If the selected label is not found, the 'out of range' error message is displayed. Pressing any key returns the display to the Program Selection Input display.

If more than one Phase is defined with the same label, then execution continues with the first matching label encountered. The last selected program label is stored in non-volatile memory and becomes the default label the next time the current Program Phase is executed. More than one Program Selection Input function can be defined and placed at any Program Phase needed. To cancel the Program Select Input and stop the Pumping Program, turn the power to the pump off and on.

If alarms are enabled, the buzzer will beep continuously while waiting for the start trigger.

11.3.10 ‘LP:nn’: Define Loop End and Loop Repetitions

Repeats execution of the defined loop ‘nn’ times.

Loop starts and loop ends are uniquely paired during looping. When an unpaired ‘loop end’ function is executed, it is paired with the most recent unpaired ‘loop start’ function executed (‘LP:ST’). If no unpaired ‘loop start’ function exists, Phase 1 is used as an implied unpaired ‘loop start’. This pairing defines the loop and the range of Phase numbers between the paired loop functions defines the scope of the loop.

When a ‘loop end’ function is executed, Program operation continues with the ‘loop start’ function paired with the loop end function. There are 2 ‘loop end’ functions: Loop continuous (‘LP:EN’) and Loop for a preset number of iterations (‘LP:nn’), indicated by ‘nn’. Each time a paired ‘loop end’ function is executed, an iteration of the loop is complete. With the ‘LP:nn’ function, after ‘nn’ number of loop iterations, the defined loop is complete and Program execution continues with the next Program Phase after the ‘loop end’ function. The loop is then no longer defined or paired.

While executing Phases within the scope of a defined loop, another ‘loop start’ and ‘loop end’ can be paired and become a defined loop within the scope of the first loop, which is referred to as the outer loop. The new loop being referred to as the inner loop. The pairing of a loop within a paired loop is referred to as nesting of loops, with each loop being one nested layer for the duration of the loops pairing. Loops can be nested for a total of 3 layers deep. Loops can only be nested within the scope of an outer loop.

11.3.11 'PS:nn': Pause Pumping

If ‘nn’ is non-zero, the Pumping Program will pause pumping (stops pumping) for ‘nn’ seconds. When

executed, the display will show until the next Program Phase is executed. After the pause interval, the next Program Phase will be executed.

To set a pause time in tenths of seconds, select the decimal point between the digits. Simultaneously press the 2 up arrow keys below the digits to set or clear the decimal point. Alternatively, press and hold the right-most up arrow key until the right-most digit scrolls to 9. After 9, the decimal point between the 2

digits will toggle on and off . Release the key when the decimal point is displayed, or cleared, as required. Now enter the required pause time from 0.1 to 9.9 seconds.

, with ‘nn’ decrementing to indicate the number of seconds

For pauses longer than the ‘99’ second maximum pause for this function, put the pause function within a Program loop. A Program section with the following functions in consecutive Phases:

[LP:ST] [LP:ST] [PS:60] [LP:60] [LP:24],

will pause the Pumping Program for 24 hours.

If ‘nn’ is ‘00’ then the Pumping Program pauses and waits for a start trigger to resume the Program. The

display will show when waiting for a start trigger.

After the start trigger, the Program will resume with the next Phase. The start trigger can be from any source, the ‘Start’/’Stop’ key, the TTL I/O Operational Trigger, or from RS-232. Any other key input will stop and reset the Pumping Program.

If alarms are enabled, the buzzer will beep continuously while waiting for the start trigger.

11.3.12 'IF:nn': Jump to Phase If External Trigger

The ‘IF’ function conditionally alters the Pumping Program’s execution based on an external signal.

When executed, if the TTL I/O Program Input pin (pin 6) is low level, then the Pumping Program continues operation with Phase number ‘nn’. Otherwise, the Pumping Program continues operation with the next Phase.

11.3.13 'Et:nn': Setup Event Trigger Jump Phase

The ‘Event’ function sets a background event trap that is triggered by an external signal.

This one time background trap, or interrupt, stays set during the Pumping Program’s entire execution until it is triggered, redefined, or reset. This function has no other effect on the operation of the pump until it is triggered.

The event is triggered with either:

1) A falling edge (high to low TTL transition) occurs on the TTL ‘Event Trigger’ input (pin 4).

2) A low level on the 'Event Trigger' input pin at the time the function is executed.

3) The RS-232 ‘RUN E’ command.

When triggered, the current operation of the pump and the Pumping Program is interrupted, and the Pumping Program immediately continues operation (jumps to) with Phase number ‘nn’.

After being triggered, the event trigger is reset. If an event trigger function is executed (either 'Et' or ES' function) while another event trap is still set, the new event trigger will replace the previous event trap. Only one event can be defined at any time.

11.3.14 'ES:nn': Setup Event Square Wave Trigger Jump Phase

The 'Event Square Wave' function operates the same as the 'ET' 'Event' function, with the exception of the triggering conditions.

The event is triggered with either:

1) The rising or falling edge of the TTL ‘Event Trigger’ input (pin 4).

2) The RS-232 ‘RUN E’ command.

Therefore, a square wave function on the inupt pin can be used to toggle the pump between 2 sections of a Pumping Program. An example of this would be a Pumping Program that switched between a slow and fast pumping rate, controlled by a square wave input.

11.3.15 'Et:rS': Event Reset

’Event Reset’ cancels a previously set event trap by either the 'ES' or 'ET' function.

11.3.16 'OUt.n': Set TTL Output Pin

Set ‘Program Output’ TTL I/O output (pin 5) to level ‘n’. If ‘n’ = 0, the output pin will be set low. If ‘n’ = 1, the output pin will be set high.

A more complex dispensing example, this Program contains different pumping requirements, including dispenses with multiple pumping rates. The first set of 3 dispenses drops down to a lower pumping rate during the dispense. When each dispense is completed, the buzzer beeps to alert the operator, then the pump waits for a start trigger before starting the next dispense.

The next set of 3 dispenses have a fixed time interval of 60 seconds between dispenses. After the last set of dispenses, the syringe is refilled by the amount dispensed, 17.25 ml. Then the buzzer beeps, to alert the operator to the start of the first set of dispenses. The process is then repeated.

11.4.5 Example 5: Control from a High-Low Pressure Sensor

Pumping Rate

r h

Program Output Pin

Event Input Pin

This example demonstrates a Pumping Program whose control depends on an external sensor. Assuming a pressure sensor that is configured to detect a high pressure point and a low pressure point, the Pumping Program individually selects whether it will react to the high or low pressure point.

The “Program Output” pin on the TTL I/O connector (pin 5) is used to select the high or low pressure point. When low, the low pressure point is selected (PH:01), and when high, the high pressure point is selected (PH:05). The Program begins by dispensing continuously at 10.0 ml/min (PH:02), while a background trap is set for the low pressure point (PH:03). To create a delay when the pressure sensor is switched from high pressure to low pressure when the “Program Output” pin is set, a small volume is pumped (PH:02, 06) before the background traps are set.

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

Event Trigger from Syringe Filled Sensor: Jump to Phase 3

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.

11.4.7 Example 7: Sub-Programs

This example shows some of the flexibilities provided by the Program Selection functions. The Pumping Program starts by refilling the syringe with 50 ml at a fast pumping rate (Phase 1), then the Pumping Program pauses for user sub-program selection (Phase 3). Then performs 5 dispenses of 10 ml at the selected rates, then refills the syringe again and pauses for the next user sub-program selection.

The user is given the option of choosing one of three defined sub-programs.

1: Dispense 10 ml at 100 ml/min (Phase 4) 2: Dispense 10 ml at 500 ml/min (Phase 7) 3: Dispense 10 ml at 750 ml/min (Phase 10)

After selecting the sub-program and pressing 'Start', the Pumping program continues execution at the selected sub-program. After the 10 ml dispense, each sub-program jumps or continues with the loop counter function (Phase 12). The first 4 loops continue Program Execution with the next user subprogram selection. After the 5th loop, the program continues with Phase 13, which jumps back to the syringe refill function and starts the whole program over.

This example demonstrates a complex interaction with external equipment, such as synchronizing with another peristaltic or syringe pump. The Program includes a variety of interactions with external equipment, which demonstrates the various control possibilities of the NE-9000.

The Pumping Program begins by canceling any previous event traps (PH:01) and raising the ‘Program Output’ TTL line (PH:02). After 5.0 ml has been dispensed at 800 ml/min (PH:03), the ‘Program Output’ TTL line is lowered (PH:04), sending a synchronization signal to another device.

Next, the pump pauses for 10 seconds (PH:10). Then it pauses again for the lesser of another 10 seconds (PH:12) or until an Event Trigger occurs (PH:11). The Program then restarts (PH:13).

RS-232 Communications

The NE-9000 Peristaltic Pump can communicate with any computer or device with an RS-232 communications port. The following assumes that the default Address Communications Mode is set.

www.SyringePump.com

Model NE-9000

12.1

cable into the socket labeled “To Computer”. Connect the other end to the serial port on the computer, or other control device. Turn power off to the pump and the computer before connecting cables.

If the pump is part of a pump network, connect a pump network cable between the socket labeled “To Network”, on the first pump, and the socket labeled “To Computer” on the next pump in the network. Repeat for each pump in the network, connecting the “To Network” socket of one pump to the “To Computer” socket on the next pump in the network. Up to 100 pumps can be networked together with a computer. See section 13, Logic Interface: TTL Input and Output, for a diagram of the rear of the pump. When communicating with a pump in a multi-pump network, each preceding pump in the network must be powered on.

Each pump in the network needs a unique network address to identify the pump to the computer. Network addresses are from 00 to 99. If the network consists of only 1 pump, set the pump’s address to 0. Also, each pump needs to be set to the same baud rate as the computer. Use the ‘Setup’ function on the keypad to set the network address and the baud rate. See section 6.14, ‘Setup’ . The '*ADR' command can also be used to set the network address.

The supported baud rates are 300, 1200, 2400, 9600, and 19200. The trade-off on baud rates is communications speed versus noise immunity. For most environments, 19200 would be acceptable. But in environments that are electrically noisy and/or over long cables, the communications signal may degrade or be disrupted, causing communications errors. In these situations, a lower baud rate may improve the reliability of the communications.

Connection and Networking

On the rear of the pump are 2 square RJ-11 (“phone jack” style) sockets. Connect the RS-232

12.2

When the pump is used in a multi-pump network configuration, precede each command with a pump address. Pumps will ignore all commands that do not have their defined network address. If the network address is not specified in the command, the address will default to 0.

After a command is sent to the pump, the pump will not accept any further communications until the current command has been processed. Completion of the command processing is indicated when the first byte of the response packet is transmitted. While the user is changing data or configurations from the keypad, command processing is delayed.

A triangle appears in the upper left corner of the LCD display after the pump has received valid communications. This triangle remains in the display until the pump is powered off or until ‘Setup Configuration’ is entered.

Communications to and from the pump use the following data frame:

Every command received by a pump in the network is acknowledged by the pump with a response packet that includes a status character indicating the current operational state of the pump.

Publication #1200-04 38

Two packet protocols are supported, Basic and Safe. The enabled communications protocol is stored in non-volatile memory, and therefore will be in affect at power up. Safe Mode provides a safer communications protocol than Basic Mode. Safe Mode detects corrupted data and loss of communication, as well as automatically transmitting status packets when an alarm occurs.

Considering that the 19200 baud rate communicates at 52 µs per bit, a small glitch on the RS-232 cable, flipping a single bit, can convert a transmitted dispense rate of 100 ml/min into 900 ml/min, the need for the Safe Mode in a production environment is evident. However, Basic Mode is excellent for simplifying early development of a control program.

While in the Basic Mode, the pump will accept either communications protocol, Basic or Safe, although the response packet will be in the current communications mode. This allows a computer’s communication’s driver to be designed with just one mode. A Safe Mode communications driver can send a ‘SAF’ command to the pump in the Safe Mode protocol while the pump is in Basic Mode. The response to the ‘SAF’ command, enabling Safe Mode, will then be in the Safe Mode protocol.

12.2.2 RS-232 Protocol: Basic Mode

Command syntax (to pump):

Response syntax (from pump):

In the “Basic” communications mode, a master-slave protocol is used, whereby the pump will only transmit in response to a received command.

When the pump receives the <basic command protocol>, <command data> will automatically be stripped of all space and control characters, and all text will be converted to upper case. This simplifies communications with the pump when commands are being manually typed in from a generic terminal emulator.

To return the pump to Basic mode when in the Safe mode, send the following packet to the pump:

(0x2) ( 0x8) SAF0 (0x55) (0x43) (0x3)

12.2.3 RS-232 Protocol: Safe Mode

Command syntax (to pump):

Response syntax (from pump):

Safe mode uses a more structured protocol including detection of corrupted communications, communications time outs, and auto-alarm responses. Safe mode is enabled using the ‘SAF’ command whose parameter setting is stored in the non-volatile memory.

Safe mode uses a modified master-slave protocol, whereby the pump transmits in response to a received command. But, the pump also automatically transmits a status packet when an alarm condition occurs.

Corrupted communications is detected using the 16 bit CCITT CRC algorithm computed over <transmitted data>. Packets transmitted and received include the CRC within the packets.

The parameter sent with the “SAF” command is the communications time out. This time out, in seconds, is the time between the reception by the pump of consecutive valid communications packets. Each time a valid communications packet is received, the time out is reset. If the time out elapses, a pump alarm will

occur, stopping the pump and the Pumping Program. The pump will display , and the buzzer will sound, if alarms are enabled, alerting the user. The communications time out timer will not restart until the next reception of a valid packet.

In addition, there is a 0.5 second packet inter-byte time out. While receiving a communications packet, and before its complete reception, if a delay of 0.5 seconds occurs between bytes, the incomplete packet will be discarded.

With the Auto-Alarm feature, whenever a pump alarm occurs, such as a pump stall, a response packet with the alarm status information will automatically be transmitted.

Until the Safe Mode is disabled, each time power is applied to the pump, the pump defaults to the Safe mode of communications, but the communications time out timer will not be enabled until the first reception of a valid packet.

Although the communications time out timer is not enabled, the Auto-Alarm feature will be enabled. Therefore, the pump will be in an Auto-Alarm only communications mode.

When power is applied to the pump, or if the system should reset, a system reset alarm occurs. The AutoAlarm feature, therefore, alerts the host computer that a pump reset has occurred.

Also, when the user changes the baud rate, the communications time out timer is disabled until the next valid communications packet.

12.2.5 Network Command Burst

The Network Command Burst feature is only applicable when communicating to a network of pumps.

This special feature allows commands to be sent to a network of pumps simultaneously. For example, changing the pumping rates simultaneously on a network of pumps.

Note: Since this special feature violates the general communications protocol of one command-one response, all of the pumps will be responding simultaneously, and therefore the communications response to a Network Command Burst will be gibberish and should be ignored.

Command Format

Command Burst => <n> <command> * Network Command Burst => < Command Burst > [Network Command Burst]

Where <n> indicates the address of the pump that is to execute <command>. Maximum address is 9. n => {0 ... 9}

Example: Simultaneously change the pumping rates of 3 pumps on a pump network as follows:

Pump 0: 100 ml/min Pump 1: 250 ml/min Pump 2: 375 ml/min

Publication #1200-04 41

Page 50

New Era Pump Systems Inc.

Assumes that the current pumping rate units of all 3 pumps are currently ml/min.

Send the following command, followed by a carriage return <CR>, (spaces are optional): 0 rat 100 * 1 rat 250 * 2 rat 375 *

12.3

If a command received by the pump is not recognized or the data is invalid, an error message will be in the <data> field of the response packet following the <prompt> field. The following are the error responses:

When an alarm occurs, the alarm must be acknowledged before any data is changed or the pump is started. Alarms are acknowledged by the user clearing the alarm message on the keypad, or the alarm status being sent in response to any valid RS-232 command. An alarm message sent automatically in the Safe Mode will not clear the alarm condition. This is to verify that the alarm message was sent to a receptive host, such as after a power failure when both the computer and the pump were reset. In this case, the pump will most likely send its reset alarm message before the computer has finished booting.

12.4

All data changed from RS-232 is stored in the non-volatile memory, except for changes to the pumping rate while pumping. All “Program Phase Data” refers to the currently selected Program Phase. Use the Phase select command (‘PHN’) to query or select the current Phase. A Phase consists of the pumping rate, ‘Volume to be Dispensed’, and the pumping direction.

Command Errors and Alarms

Command is not recognized (‘?’ only) NA Command is not currently applicable OOR Command data is out of range COM Invalid communications packet received IGN Command ignored due to a simultaneous new Phase start

RS-232 Command Set

A packet without a command is interpreted as a status query. The addressed pump responds with a status only response packet.

Except where noted, a command without any parameters is a query command. The response packet data will include the requested data. In general, the query response data will be in the same format as the parameters for setting the command. For example, the query volume command ‘VOL’ will respond with ‘<float>‘ as the response ‘<data>‘.

Otherwise, the command is a set command. If the data was set, a status only response packet will be sent. If the data was not set, the response packet will include an error (<command error>) message indicating why the data was not set.

All commands are upper case.

TUBING INSIDE DIAMETER

DIA [ nn / nn ]

Set/query peristaltic tube inside diameter. Set is only valid when the Pumping Program is not operating. Setting the tube inside diameter resets any entered calibration volumes. The new diameter is used for calibration.

CALIBRATION

CAL <float>

Calibrates the tubing diameter using <float> as the measured dispense volume, and the volume dispensed or withdrawn, according to the current pumping direction. The calibration value cannot be queried. The pump must be stopped to calibrate.

12.4.1 Program Function Commands

The following commands are relevant to the currently select Program Phase. Note: During a Pumping Program’s operation, the currently selected Phase can change automatically.

PHASE NUMBER

PHN [ <phase data> ]

Set/query currently selected Program Phase:

Set: Currently selected Phase is set to <phase data>. Previous Phase is stored in non-volatile memory and the requested Phase is recalled from the non-volatile memory. Set is only valid if the Pumping Program is not operating.

Query response: <phase data> Currently selected Phase.

PUMPING PROGRAM FUNCTION

FUN [ <phase function> ]

Set/query the Pumping Program Phase’s function.

This command is relevant to the currently selected Phase. Set is only valid if the Pumping Program is not operating

For a more detailed description of Program commands, see sec. 11.3, Program Function Descriptions.

When a Phase’s function is set to a “Rate Data Function”, use the ‘RAT’, ‘VOL’, and ‘DIR’ commands to setup the pumping parameters.

RAT Pumping rate. ‘RATE’ INC Increment rate. ‘INCR’ DEC Decrement rate. ‘DECR’

STP Stop pump. ‘STOP’ JMP <phase data> Jump to Program Phase. ‘JP:nn’ LOP <count data> Loop to previous loop start ‘nn’ times. ‘LP:nn’ PRI Program Selection Input. 'Pr:In' PRL <count data> Program Selection Label definition. 'Pr:nn' LPS Loop starting Phase. ‘LP:ST’ LPE Loop end Phase. ‘LP:EN’ PAS <number data> Pauses pumping for ‘nn’ seconds. ‘PS:nn’ PAS <n.n> Pauses pumping for 'n.n' seconds. 'PS:n.n' IF <phase data> If Program input TTL pin low, jump to Phase. ‘IF:nn’ EVN <phase data> Set event trigger trap. ‘EV:nn’ EVS <phase data> Set event square wave trigger trap. 'ES:nn' EVR Event trigger reset. ‘EV:RS’ BEP Sound short beep. ‘BEEP’ OUT <TTL level> Set programmable output pin. ‘OUT.n’

Rate Data Functions

Non-Rate Data Functions

PUMPING RATE

RAT [ <float> [ <rate units> ] ]

Set/query pumping rate.

<rate units> => OM = Oz/min

MM = mL/min

Publication #1200-04 43

Page 52

New Era Pump Systems Inc.

OS = Oz/sec MS = mL/sec

Applicable only with “Rate Data Functions”.

When setting the pumping rate, if the current Phase’s function is not ‘RATE’, then <rate units> is not applicable.

While pumping, the pumping rate can only be set if the current Phase function is ‘RATE’ and the next Program Phase’s function to be executed is not ‘INCR’ or ‘DECR’. Also, while pumping, <rate units> cannot be set.

The new pumping rate will only be stored in non-volatile memory if the Pumping Program is not operating.

When the pumping rate is queried while pumping, the response will be the current pumping rate and units. Otherwise, the response will be the rate setting and units, if applicable. With the ‘INCR’ and ‘DECR’ functions, these two responses are not the same.

If a pumping dispense time is set, the query response will be the dispense time in [minutes : seconds].

PUMPING DISPENSE TIME

TIM [<nn> : <nn>]

Set pumping dispense time and rate units to [minutes : seconds].

Query will return the current time setting, or the pumping rate if dispense time not set.

www.SyringePump.com

Model NE-9000

VOLUME TO BE DISPENSED AND SET VOLUME UNITS

VOL [ <float> | <volume units>]

Set/query volume to be dispensed: <float> Applicable only with “Rate Data Functions”. Can only be set when the Pumping Program is not operating. The volume units are set according to the current diameter setting. Do not send the volume units when setting the volume. Example: VOL 12.45 Sets the current phase “Volume to be Dispensed” to 12.45.

Set volume units: <volume units> Overrides the default volume units set when the diameter is set. Example: VOL OZ Sets all volume units to Oz.

Query response:

PUMPING DIRECTION

DIR [ INF | WDR | REV ]

Set/query pumping direction

INF = Dispense WDR = Withdraw REV = Reverse pumping direction

12.4.5 System Commands

SET PUMP NETWORK ADDRESS AND BAUD RATE

* ADR [ <address> [ B { 19200 | 9600 | 2400 | 1200 | 300 } ] ]

This is a special system command that will be accepted by the pump regardless of its current address. Once set, the pump will only respond to commands with the set address and at the specified baud rate.

Note: Once DUAL or RECP is set, the pump will only respond to commands that are preceded by the ‘*’ character. To exit DUAL or RECP mode, reset the address: * ADR 0

Example: *ADR Query current address setting

[DUAL | RECP]

Set/query pump network address

<address> => <n> [<n>] <address> Valid range: 0 to 99

B { 19200 | 9600 | 2400 | 1200 | 300 } will change the baud rate as indicated. NOTE: The

command response and all further communications will be at the specified baud rate.

DUAL Sets the pump to Dual Pumping mode with a secondary pump.

RECP Sets the pump to Reciprocating Pumping mode with a secondary pump.

With both Dual and Reciprocating modes, the baud rate defaults to 19,200.

*ADR 3 Set pump network address to 3. The pump will now only respond to

commands with address 3

*ADR 5 B 1200 Set the pump network address to 5 and the baud rate to 1200. The

command response will be at 1200 baud

ENABLE SAFE COMMUNICATIONS MODE

SAF [ <time out> ]

Set/query Safe communications mode setting. <time out> => <n> [ <n> [ <n> ] ] <time out> Valid range: 0 to 255.

If <time out> = 0 then Basic communication mode is set, disabling Safe mode,

If <time out> > 0 then Safe communications mode is enabled. After the reception of this command, valid communications must be received every <time out> seconds.

FIRMWARE VERSION QUERY

VER

Response: NE<model>V <n> . <n>

where ‘<n>.<n>‘ is current firmware version number.

Set is not applicable.

MASTER PROGRAM RESET

* RESET

Clears program memory and resets communication parameters to Basic mode and address 0.

This is a special system command that will be accepted by the pump regardless of its current address.

12.5

Before beginning to develop pump control software for a computer, first setup and experiment with the pump’s communication. After attaching the pump to the computer, run a terminal emulation Program on the computer. A generic terminal emulator, supplied as standard software with many computers, can be used to communicate with the pump in the Basic communications mode.

Publication #1200-04 48

Getting Started With RS-232

Page 57

New Era Pump Systems Inc.

New Era Pum p Sys

tems Inc.

A terminal emulator is available at, (www.syringepump.com/accessories.htm#software) for demonstration purposes only, which allows more complex control of the pump. Also, this terminal emulator contains a “Pump Programming Language” (PPL™), which allows Pumping Programs to be developed using symbolic text, modified, and stored in computer files, then downloaded to the pump.

With a generic terminal emulator, setup the terminal emulator with the same baud rate as the pump and with an 8 bit data, no parity, and 1 stop bit (8N1) data frame. Set the communications port to the port that is attached to the pump. Also enable local echo (half-duplex) and turn flow control off.

From the terminal emulator, you can interactively control the pump by typing in commands on your computer and seeing the pump’s responses on your screen. This will give you a feel for how the commands work in addition to allowing you to quickly develop the control sequence that will eventually be coded into the software being developed.

The final benefit of using a terminal emulator is the elimination of several variables if the control software does not work properly. If the pump works correctly with the terminal emulator, then this verifies that the hardware is working properly and will work with any software. Any communications problems can then be narrowed down to the control software.

SyringePumpPro software provides licensed Windows GUI based control program for this pump.

Note on USB: If an RS-232 port is not available on your PC, the pump may be operated through a USB to RS-232 cable (available as an accessory). The PC will create a virtual RS-232 communications port that communicates through the USB to RS-232 cable. The terminal emulator can communicate through this virtual port.

Logic Interface: TTL Input and Output

www.SyringePump .com

Farmingdale, NY

Figure 2: Rear of Pump

On the rear of the pump is a DB-9 connector, below the ‘TTL-I/O’ label, which is used for TTL I/O. The logic signals on this connector permit bi-directional control with external equipment.

Control input TTL logic levels must be held steady for a minimum of 100 ms to be recognized. To minimize the possibility of false signals caused by glitches and ringing, which could be caused by the closure of mechanical switches, TTL control inputs are software filtered. With a sampling period of 50 ms, glitches of less than 100 ms are filtered out.

Edge detection requires the detection of a change in TTL levels. With a minimum of 100 ms to detect a level, an edge requires a minimum of 200 ms to be detected. Since the next level change can be detected in 100 ms, creating another edge, the maximum edge to edge frequency is 10 Hz.

Edge changes to the ‘Pumping Direction’ and ‘Operational Trigger’ inputs must occur at least 50 ms apart.

Model NE-9000

Falling edge refers to a logic high to logic low transition. Rising edge refers to a logic low to a logic high transition. To guarantee recognition of logic levels, voltages on the input lines must be within the following ranges:

TTL logic low (0): 0 to 1.5 V

logic high (1): 3.5 to 5.25 V

The Vcc and Ground pins, pins 1 and 9, are for logic reference only. To assure proper voltage levels, the Ground pin should always be connected to the signal ground of a sensing or controlling device that is attached to any other pin on the TTL I/O connector. The Vcc pin should not be used to source current. The TTL I/O pins are defined as follows:

Pin # Definition Type Function

1 Vcc (5V) Reference Logic high reference. Power on indicator.

2 Operational Trigger Input

3 Pumping Direction Input Changes pumping direction according to setup

4 Event Trigger Input Event input or user definable input

5 Program Output Output Program controlled output or user definable output

6 Program Input Input Program conditional input read by the “IF” program function.

TTL I/O Operational Controls

While the user is changing settings or configuration from the keypad, external control by the ‘Pumping Direction’ and ‘Operational Trigger’ inputs will be ignored. These controls will also be ignored if an alarm condition exists.

Operational Trigger (Pin 2): The input signal on this pin controls the operation of the Pumping Program. Its functionality is user configurable. Use the ‘TR:nn’ Setup Configuration to configure this input pin (See Section 10.7, TTL I/O Operational Trigger Configuration).

Each option defines when the Operational Trigger input is activated. When activated, the trigger emulates the ‘Start/Stop’ key:

Publication #1200-04 50

Page 59

New Era Pump Systems Inc.

Foot Switch: Operates like the ‘Start/Stop’ key, whereby each falling edge (contact to ground) either

starts or stops/pauses the Pumping Program.

Foot Switch Hold: Falling edge starts the Pumping Program and the rising edge stops the Pumping

Program. With a foot switch, the Pumping Program will run while the foot switch was held down.

Foot Switch Reversed: Operates like the ‘Start/Stop’ key, whereby each rising edge either starts or

stops/pauses the Pumping Program.

Level Control: Falling edge stops/pauses the Pumping Program, Rising edge starts the Pumping

Program. This configuration can be used with a contact closure timer or in an automation setup, allowing logic level control over the operation of the pump.

Start Only: Falling edge starts the Pumping Program. This configuration only allows the starting of

the Pumping Program. This would be useful, for example, with a laboratory animal trained to press a lever. The animal can start the Pumping Program, but repeated presses would have no effect until the Pumping Program permits it.

Start Only Reversed: Same as ‘Start Only’, but operates on the Rising edge to start the Pumping

Program.

Stop Only: Falling edge Stops the Pumping Program. This configuration only allows the

stopping/pausing of the Pumping Program. This would be useful, for example, with an end of travel limit switch. Also, this switch can be used as a power on homing switch.

Stop Only Reversed: Same as ‘Stop Only’, but operates on the Rising edge to stop the Pumping

Program.

www.SyringePump.com

Model NE-9000

Pump Motor Operating (Pin 7): This output provides an external signal indicating when the pump

motor is operating. This pin is configured with the command. When set to 0, the output is only at logic high when the motor is operating (pumping). When set to 1, the output is logic high when the motor is operating or when the Pumping program is executing a pause timer. Otherwise, the output is a logic low.

Pumping Direction Controls (Input: Pin 3; Output: Pin 8): Allows bi-directional control of the pumping direction. The input pin, when activated, emulates the pumping direction key, changing the pumping direction. This function, therefore, is only applicable where the pumping direction key would be

applicable. The function of the input pin is configured with the remote command.

When the mode is set to reciprocating pumps ("RE" setup command or "0" remote), then if the current pumping direction is withdraw, a falling edge sets the direction to dispense. If the current pumping direction is dispense, a rising edge sets the direction to withdraw. Otherwise, this input pin has no effect.

When the mode is set to dual pumps ("dU" setup command or "1" remote), then if the current pumping direction is withdraw, a rising edge sets the direction to dispense. If the current pumping direction is dispense, a falling edge sets the direction to withdraw. Otherwise, this input pin has no effect.

Dual and reciprocating pumping systems are created using 2 pumps attached with the accessory cable CBL-TTL-1.

The output pin provides an output signal to external devices indicating the direction of pumping. A logic low indicates withdraw, and a logic high indicates dispense. For example, this pin can be used to control an external valve.

setup command, or the "DIN"

14.3.3 Automation Cable: Dual Pumps Control Cable

Part #: CBL-DUAL

Using two NE-9000 peristaltic pumps, this cable creates a dual pumping system, with both pumps operating in the same direction.

This cable is attached to two NE-9000 peristaltic pumps via their RS-232 connectors. In this setup, with the pumps configured for this operation, one pump acts as the Master controller. The pumps can be set to Dual Pump Mode, whereby the second pump will always follow the program on the first pump, including starting, stopping, direction changes, and rate changes.

When either pump stops, for any reason, the other pump will stop.

14.3.4 Valve Controller

Part# ADPT-VALVE-INTERFACE-1 (For one pump) Part# ADPT-VALVE-INTERFACE-2 (For two pumps, includes CBL-TTL-1)

Provides a control interface for your electronic valves. Attach your electronic valves, and the interface will control the activation of the valves. The 2 pump interface is used to create a continuous dispense/refill system.

14.3.5 Foot Switch

Part #: ADPT-2

Allows the pump to be operated from a foot switch. Attaches to the TTL I/O connector.

14.3.6 Lockout Disable Key

Part#: ADPT-LOCKOUT-KEY

Enables setting Keypad Lockout mode and allows changing of settings while Keypad Lockout is set.

14.3.7 Firmware Upgrade

Part#: CPU-NE9000, Upgraded firmware.

Contact your dealer for this upgrade and to determine the current available version of the pumps internal firmware.

Maintenance: Periodically, a new tube should be used or a new section of peristaltic tubing should be used. Add grease to the Cassette shaft and the surface of new tubing.

Pump head may need to be replaced once a year depending on usage.

The mechanism should be kept clean to prevent wear and tear.

RS-232 Communications: If no RS-232 communications is possible or garbled responses are received from the pump, check the following:

If the triangle appears in the upper left of the LCD display, then the pump is receiving valid communications. The communications problem is probably with the receiving communication application or with the receive line on the cable.

Troubleshooting and Maintenance

If the Basic communications mode is used, check if the pump is in Safe communications mode. See section 12.2, RS-232 Protocol:, for instructions on how to change the communications mode.

Verify the pump’s baud rate and network address. To set the RS-232 communications parameters, see section 6.14, ‘Setup’ .

Using a lower baud rate may also improve the reliability of the RS-232 communications.

Pump stalls and is unable to turn: This may be because the pumping rate is set too high. Reduce rate.

Peristaltic tubing being used may be too rigid for this pump. Replace tubing. Liquid may be too viscous or there may be too much pressure on the system.

There may be too much tubing in the pump head, reduce distance between tie-raps and recalibrate pump, refer to section 4.2.1.

Pump doesn’t stop after dispensing a set volume: The pump was previously setup with a multiple Phase Pumping Program. To simply dispense a fixed volume at a fixed pumping rate, the second Program Phase must be the ‘Stop’ function. See section 11.1, How to Enter Pumping Programs, for instructions on changing the Pumping Program.

Pump stops pumping after a period of time: A dispense volume has been set. Verify that the dispense volume is set to 0.

Tube Chemical Characteristics

Tubing Chemical compatibility list mentioned is only a guide. The user is responsible to determine

the tubing compatibility to the chemical being used.

This Peristaltic pump will only work with tubing with 1/16 [1.6mm] wall, peristaltic tubing that is relatively flexible, and that can be easily compressed.

Thus we have a couple of recommendations:
