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!

2 History 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 communica­tion 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 configura­tion 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.

4 Replacement 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.

e Remove 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
a Software 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.

bA pressure 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.

4.7 Calibration of the battery capacity
Each battery is subject to a chemical process with a slowly decreasing running time. After many charge and
discharge cycles the battery may not have the capacity which provided the running time shown in the menu
"CAP".
To adjust the running time of the used battery please follow the steps mentioned below:

- Go in the configuration mode of the pump.

- Select address "368" in the left display.

- Enter the data "615" in the right display and press the "START/STOP" key to accept the data. This will set

the battery discharge time to the maximum of >10 hours.

- Switch the pump off.

- Be sure you have unplugged the line connection.

- Switch the pump on normally and let the pump running in battery mode until its self switching off.

- Load the battery for more than 16 hours by plug in the line.

- Switch on the pump and start an infusion with a rate of 60ml/h. The infused sum at this rate is now equal to

battery operating time in minutes.

- Leave the pump running until the pump its self switching off again.

- Switch the pump on while keeping the key "1" pressed. The right display now shows the capacity of the

battery in minutes. Multiply this time x 0.8 and enter the result on address "368" in the configuration mode.
This time defined from now on the running time of the pump including a 15 minutes pre-alarm (only after a
full charge).

- If this time is less than 4 hrs, you should replace the battery (part 10.016). If the specific time > 4hrs is not

necessary, the battery has to be changed only if the time less than 3hrs, with respect to environ pollution.
