Introduction
The Boxer iD Driver is a powerful digital and programmable controller designed specifically for
use with the peristaltic pumps series 25K, 15KS/QQ and 9K/QQ with stepper motors.
Features include:
►
3 Runni
ng modes (dispense, dose and analogue
)
► Calibration for volumetric dispense
► Automatic stall and open lid detection
►
Push button or remote inputs
► Acceleration, deceleration, time interval, and suck-back settings
1.1
Dispense Mode
In dispense mode the pump is switched on and off by the enter key. The display will show the
dispense volume. During running or prior to starting the speed can be
changed with the up and down keys. Programmable settings are: current, calibration, suck back, acceleration, deceleration, direction, stall and lid detections.
1.2 Dose Mode
In dose mode the pump will run a predefined dosing cycle with paused interval. The display
will show the dosed volume and count down during the
pause interval. Prior to starting the dose volume is set. Programmable setting are: current, calibration, dose speed,
dose interval, number of cycles, suck back, acceleration, deceleration, direction, stall and lid
detection.
1.3 Analog Mode
In analog mode the driver acts a pure analog driver. Inputs are: on/off, direction and
speed. The display will show the running speed. Programmable settings are:
current, acceleration, deceleration, speed range, stall and lid detection.
2.0 Setting-Up
With the power supply switched off, connect the iD Driver via the blue terminal block:
GND
→ GND
24V DC → Vin
Connect the 4 colour coded wires from the stepper motor also to the blue terminal
block:
Green → A2
Black → A1
Red → B1
Blue → B2
For stall / lid detection and remote inputs, refer to section 5.2.
Switch the power supply on.

3.0 Operation
Whe
n powered up the display initially shows BOXER PUMPS. On first operation or following a reset the driver enters Dispense mode. Thereafter the driver will always return to mode last used prior to switching off.
The driver is operated using the 4 keys on the PCB under the display:
From left to right, these are referred throughout this manual as ’settings’, ‘down’, ’up’ and
’enter’. The above symbols are used in the mode settings menus (Appendix A, B and C).
3.1 Moving between modes
The following section assumes the driver is initially in Dispense mode and the
user wishes to change to Dose mode.
1 Press and hold ‘settings’. The display first shows ‘Settings’, then ‘Mode
Dispense’.
2 Press ‘enter’. The display first shows ’Changes Mode’, then ‘Mode Dis-
pense’ (with ‘Mode’ flashing).
3 Use Up and Down keys to select new mode, example ‘Mode
Dose’ (with ‘Mode’ flashing).
4 Press ‘Enter’. The display first shows ‘Mode Set’, then ‘Mode Dose’.
5 Press ‘settings’. The display first shows ’Exiting Settings’, then enters
the Dose Mode’
3.2 Using the Dispense mode
With the driver in Dispense mode the ‘Run RPM’ is shown.
1 Using the ‘up’ and ‘down’ keys the rpm can be adjusted.
2 All other settings including calibration can be adjusted in the Dispense
Settings Mode. See section 4.0.
3 Press ‘enter’ to start running.
4 The display counts up the dispensed volume (calibration is needed).
5 When running the speed can be increased / de creased using the ‘up’
and ‘down’ keys.
6 Press ‘enter’ to stop running. The dispensed volume is shown.
7 Press ‘enter’ as required to start / s top the dispensing.
8 If ‘settings ’ is pressed when stopped, the display returns to the ‘Run
RPM’. Speed can be adjusted and the dispensed volume is automatically reset to 0 ml.

3.3 Using the Dose mode
With the drive
r in Dose mode the ‘Dose ml’ is shown.
1 Using the ‘up’ and ‘down’ keys the dose volume can be adjusted.
2 All other settings including calibration can be adjusted in the Dispense
Settings Mode. See section 4.0.
3 Press ‘enter’ to start running.
4 The display counts up the dispensed volume.
5 Once the dose volume is reached the driver enters a interval pause.
The display counts down the time before the next dose commences.
6 Dosing continues for the set or infinite number of cycles.
7 Press ’enter’ to stop the cycle. The display first shows the volume ob-
tained in the last dose, then returns to the ‘Dose ml’ display.
3.3 Using the Analogue mode
With the driver in Analogue mode the ‘Analog RPM’ is shown. The driver acts
as a pure analogue driver and runs at all times runs according to the analogue
inputs.
The inputs are:
►
On / off (pulled up, with no input = ‘on’).
► Direction (pulled up, with no input = ‘CW’).
► Speed 0 to 5 V* (range defined in the settings, see section 4.12).
* with no speed input the RPM will drift around 20 rpm!
The location of the inputs are shown in section 5.1.
Once in Analogue mode the driver can only be stopped by changing to a different mode (press and hold ’settings’).
Since the inputs are partly also shared with the keys on the PCB, when running in analogue mode pressing and holding ‘up’ will reverse the direction
while pressing and holding ‘enter’ will stop the pump.
4.0 Programmable Settings
The iD driver has 12 programmable settings which are used in some or all of
the three modes. The menu structure of each of the modes is shown in a pictorial form in appendix A, B and C.
4.1 Current
(used in Dispense, Dose and Analogue mode)
It is a characteristic of stepper motors that they will run hot at slow speeds. To
reduce temperature the current setting should be set to the lowest possible
setting which does not stall the pump.
Default = 4.16A

4.2 Calibrate
(Used in Dispense and Dose mode)
For volumetric dispensin
g the driver must be calibrated to the pump and tube
type / size. The calibration can be made ‘dry’ (inputting flow according to the
pump / tube data or ‘wet’ by dispensing a measured volume over a period of
several revolutions.
Default = 2 ml / revolution
4.3 Suck Back
(Used in Dispense and Dose mode)
To prevent dripping the driver c
an be programmed to reverse the flow direc-
tion by fractions or whole revolutions when the pump stops.
Note: When restarting any programmed suck back will introduce a volumetric
error. This should be added to the required volume.
Default = 0.0 revolutions
4.4 Acceleration
(Used in Dispense, Dose and Analogue mode)
The acceleration setting will ramp up the speed rather than providing a hard
start. The setting is 1 (slowest ramp up) to 255 / Max (fastest ramp up). For
high speed operation this is useful to prevent stalling.
The acceleration period is taken into consideration for all volumetric dispensing.
Default = 200
4.5 Deceleration
(Used in Dispense, Dose and Analogue mode)
Similar to acceleration this setting prevents a hard stop.
Default = Max (255)
4.6 Direction
(Used in Dispense and Dose mode)
The direction is either CW (pumping left to right) or CCW.
Default = CW
4.7 Inputs Enable
(Used in Dispense, Dose and Analogue mode)
The inputs enable is an advanced feature whi
ch monitors the pump for either
the pump lid (clamp) being open or the pump stalling. In both cases the pump
will stop.
In the case of lid being open, the pump will automatically re-start when the lid
is closed. In the case of stalling, the driver will ask if the pump should be restarted.
The inputs are detailed in section 5.2.
This feature is only available on 25K and with sensor configuration.
Default = both input are not activated

4.8 Reset
(Used in Dispense, Dose and Analogue mode)
The reset will return all settings to the factory default settings.
4.9 Dose Speed
(Used in Dose Mode)
This setting determines the
speed (RPM) of dosing.
Default = 300 rpm
4.10 Dose Interval
(Used in Dose Mode)
The dose interval (hours, minutes, secon
ds) determines the interval between
doses.
Default = 5 seconds.
4.11 Times
(Used in Dose Mode)
The times setting determine
s how many times the dose cycle will be repeated.
It can be set between 0 to 99 or infinite.
Default = infinite
4.12 Max Speed
(Used in Analogue Mode)
The max speed setting determines the p
ump RPM with an analogue speed
input at 5V. Between 0 to 5V the RPM will be a linear response.
Default = 300 rpm
