1.6 Special configuration options
-Configuration of a reminder alarm for the safety standard check:
First the service interval has to be configured either in months or in hours of operation, or both (addresses
393, 394).
Next the last service date has to be entered on address 390. Any value higher than 0 entered at the adresses
393 and/or 394 will release the reminder alarm after the set service interval has elapsed (check also the
correct settings of the internal clock).
-PC configuration tool "AConfig":
With this additional software the pump may be configured from a PC over the serial port. This software
may be available from your local distributor or our service department.
-IV-set definition:
Allows the individual calibration of up to 4 dedicated IV-sets over the full infusion rate range. Please
contact your local distributor or our service department for further information.
After changing the configuration a function check and a control measurement has to be made!

2History and pump configuration printout
2.1 Connecting of the ARGUS414 to the serial interface
Caution: The infusion pump must be disconnected from the patient before any connection
over the serial interface can be done.
A connection of the ARGUS414 to a computer is useful to the read the actual configuration or history of the
pump. Even a simple monitoring of the pump can be done over the serial interface RS-232.
The connection of the infusion pump with your computer over the interface can be done by connecting the
interface cable and adapter (part 12.011 and part 12.012) and the following steps:
-Connect the RS-232 interface cable to outlet (32) of the infusion pump and to the serial port of your PC.
Note in which port (COM1 or COM2) you have pluged in.
-Start your terminal program on your computer. A simple terminal program, e.g. "Hyper Terminal" is
included in every MS-Windows 9x and Windows NT systems, but must be installed first if necessary.
-Be sure that you have selected the right serial port (COM1 or COM2) and set the following communica-
tion parameters:
Bits per second: 4800 Baud
Data bits: 8 bits
Parity: None
Stop bits: 1 bit
Protocol: None
-Go to the next step in one of the further chapters, depending on your intention.
2.2 Configuration printout
-Switch the pump on while keeping the keys "MODE" and "START/STOP" pressed and go in the configura-
tion mode.
-Select address 399 on the left hand display.
-Start capturing text received over the serial interface, e.g. by selecting "capturing text..." in the menu of
the Hyper terminal. A text file which contains the actual configuration printout will now be generated.
-Enter the data 3456 on the right display of the pump.
-Press the "START/STOP" key.
-The pump will now transfer the actual configuration of the pump in the format mentioned below.
-Stop the capturing of the text received; this will also close the text file generated.
-The generated text file can be opened and printed out by any text program.

2.3 History printout
The transfer of the last events made on the pump can be done either by this way:
-Switch the pump on while keeping the key "100" pressed.
Or by this way:
-Switch the pump on while keeping the keys "MODE" and "START/STOP" pressed and go in the configura-
tion mode.
-Select address 399 on the left display of the pump.
-Start capturing text received over the serial interface, e.g. by selecting "capturing text..." in the menu of
the Hyper terminal. A text file which contains the history printout will now be generated.
-Enter the data 4567 on the right display of the pump.
-Press the "START/STOP" key.
-The pump will now transfer the last events made on the pump in the format mentioned below.
-Stop the capturing of the text received; this will also close the text file generated.

2.4 Monitoring of the ARGUS414
Caution:The monitoring of the infusion pump ARGUS414 over the serial interface of a PC is only for
demonstration purposes; any connection with patients has not been tested under the
conditions of EN 60601-1 and are not allowed.
-Switch the pump on with an inserted filled infusion set.

A sample of a monitoring session:
-Switch the pump on with an inserted filled infusion set.
-Type "Ctrl+N" to set the pump in remote mode.
-Type "Ctrl+B", then "01200200" and then "Ctrl+C" which sets the rate to 12.0 ml/h and an infusion total of
200 ml. The rate should now be shown in the left display of the pump.
-Type "Ctrl+R" to start the infusion.
-Type "Ctrl+T" to stop the infusion.

3Fault finding
The fault code in case of a failure is displayed by pressing "MODE" key (21). (F-XX) appears in display (9),
and the source of the failure is listed in the table below:
Error Error reason Assembly group

F-23...24 RAM test Mainboard
F-25 CPU test Mainboard
F-26 Invalid function menu
F-27 EEPROM data invalid Mainboard
F-28 RTC (real time clock) data invalid Mainboard
F-29 Stepper motor power test Mainboard
F-31 1.2 Volt supply out of range Mainboard

4Replacement of parts
4.1 Disassembly of the pump
NOTE: The exploded views in the appendix show the individual mounting steps.
CAUTION!
Switch the unit off and disconnect the mains cable from the power outlet before opening the housing. The
antistatic protection have to be strictly adhered to when the ARGUS infusion pump is disassembled (the use
of an antistatic table mat and a grounded clip are recommended, for example).
aDisassembly of the hood:
Remove the four screws on the side and on the rear wall, lift hood up and disconnect the plug-type
connector of the drop barrier.
bDisassembly of the main printed board assembly:
Disconnect the plug-type connector of the main printed board assembly and unscrew the two lateral
attachment screws. Please refer to the wiring diagram in the appendix.
cDisassembly of the front panel:
Use a ball-headed hexagon screwdriver to unscrew the two attachment screws from the rear and remove
the front panel. This special screwdriver can be obtained from the service department on request.
dDisassembly of the pump unit:
By unscrewing the four attachment screws, the whole pump unit can be removed from the front panel.
eRemove the pump door:
The pump door can be remove without any tools by pulling it out in the
direction of the arrow according to the drawing. For the dismounting and the
mounting the opening angle from 30 to 45°has to be kept.
4.2 Replacement of the EPROM or the display board
aSoftware updates may reset automatically the default values in the EEPROM. You are requested to write
down the actual contents of the addresses before you replace the EPROM or the display board. Afterwards
you have to re-enter these values in the program mode. If a write protection code has been used before, the
same code has to be programmed again.
bApressure sensor calibrating is necessary when replacing the pressure sensor, a pressure sensor
calibration and a volume calibration are necessary when replacing the EPROM or the display board. Be
careful and carry out the described instructions step by step.

4.3 Pressure sensor calibration
1Go to the program mode (without IV-administration set).
2Enter in address 399 the value 1234.
3Press the key "START/STOP"
The display shows e.g. [Set] [-2- ]. Choose the IV set (no. 1 to 4) by pressing the key [1].
4Press the key "START/STOP" (The pump mechanic runs with a rate of ca. 200 ml/h).
The display shows [CAL.] [door]. By pressing the key "1" it is possible to show the stored value in mV
in the display.
5Press the key "START/STOP". The offset voltage, without IV-set, will be stored.
The stored value will be acknowledged by a sound.
6Press the key "MODE".
The display shows [CAL.] [0bAr]. By pressing the key "1" it is possible to show the stored value in mV
in the display.
7Install an used (milled) IV-administration set (Open the roller clamp).
8Start the pressure build-up by occluding the tube on the patient side to control the mechanical pressure
limit.
Minimum 1.2 bar has to be reached for a successful calibration.
9Gradually decrease the pressure by removing the occlusion.
10 Wait ca. 30 sec., then activate the key "START/STOP". The reference value for sensitivity calculation will
be stored. The stored value will be acknowledged by a sound.
11 Press the key "MODE".
The display shows [CAL.] [1bAr]. By pressing the key "1" it is possible to show the stored value in mV
in the display.
12 Start the pressure build-up again, wait until the manometer shows 1 bar, then activate the
key "START/STOP". The absolute value at 1 bar will be stored. The stored value will be acknowledged
by a sound.
13 Gradually decrease the pressure.
14 Turn the pump off- and on again.
15 Select the rate at 500 ml/h.
16 Press the key "START/STOP".
17 Start the pressure build-up to control the electronic pressure limit.
18 The alarm must be activated at ca. 700 mbar ±100 mbar if the default value = "7".
If the result is not satisfactory repeat the sensor calibration.
19 Switch the pump off.
