1Technical description
Control:
The microprocessor controlled Volumed® µVP7000 Chroma is a peristaltic driven infusion
pump and intelligent software monitoring of all critical functions. The stepper motor
transfers movement to a drive belt, which is directly connected to the finger peristaltic
mechanism. All important infusion parameter are displayed on very well readable LCD and
LED displays. Entering parameters is done via a touch field.
The pump uses two independent microprocessors mutually checking each other. In case
of a discrepancy, the pump is stopped immediately and an acoustic alarm is emitted.
To achieve the accuracy stated in the specifications, the pump must be calibrated to the
used infusion set.
Power Supply:
A switching power supply directly mounted on the main PCB allows a wide input range of
110 –230V AC, 50 - 60 Hz while a regulated 15V DC output.
Furthermore two DC-DC converters are used to provide the 5V and 3.3V power. On the
primary inlet the pump is fused. When changing the fuse, follow these instructions:
!!CAUTHION!!:
-Before changing a blown fuse, find out the reason why it is blown.
-Only carry out repairs when device is powered off and disconnected from mains.
-Take note of warning signs!
In addition to the switching power supply, an internal battery enables the user to use the
pump independently from mains supply. The battery is a NiMH Battery (9,6V, 2150 mAh,
Part No. 71160) and is always being charged when the pump is plugged into mains. The
battery is charged on a cyclic basis, which ensures a long battery life. A complete charge
is complete within approximately 10 hours. Then the charging is set to trickle charge, to
guarantee the battery will not self-discharge on mains. To monitor the charging a counter
is used. A battery empty alarm is triggered if either the counter or the measured voltage
falls below a certain value.
Sensors:
The pump uses several sensors to monitor its functions.
The air in line sensor consists of two opposite placed ultrasonic sound producing piezo
crystals. One is the transmitter, the other is the receiver. Ultrasonic waves are transmitted
in with liquid filled tubing much better than in empty tubing. This allows determining, if air
or liquid is inside the tube. The air in line detector has the same accuracy at every flow
rate.
The pressure is measured on the outside of the tubing. Depending on the pressure within
the IV-line, the tubing acts with a certain force on the pressure sensor. This force is

SH-7000-Chroma-EN-04/17 6
measured and used for calculation of the pressure inside the system. The pressure sensor
requires a mechanical and electrical calibration (mbar).
The Easy Clip functions as a drop counter and is fastened to the drip chamber. Drops are
detected via light barrier in the Easy Clip. The Volumed® µVP7000 Chroma is not
regulated through the drop count, the Easy Clip serves as an additional safety feature
allowing to detect reverse flow, free flow, upstream occlusion or and empty bag.
Using a hall sensor the rotation of the peristaltic system is monitored. If the measured
speed does not correspond to the set rate, the pump is stopped and an acoustic alarm is
emitted. This allows checking the mechanical and electrical functioning of the peristaltic
system.
All verification tests were performed with the IV sets Volumed®Set Standard APPF512
and the Volumed®Set silicon APSF227.
Software:
The microcontrollers are equipped with an internal flash memory (512kB). For software
updates and data transfer the Volumed® µVP7000 Chroma is equipped with infrared
interfaces. This enables to carry out these updates without having to open the housing.
The required USB interface (Part No: 5316) and arcomed ag’s own PremiumLink™
software are compatible with all common Window operating systems.
!!WARNING!!:
The Volumed® µVP7000 Chroma is turned completely off during a software update to
access the internal flash memories. At this stage any false manipulation may cause pump
failures. It is of utmost importance that only trained personnel carry out updates because
there are several variations of carrying out updates. arcomed ag is not responsible for
pump damages because of false handling. There is no physical damage done to the
pumps, but the processors need to be reinitialized. Only arcomed ag may carry out the
task of re-initialisation. Furthermore are updates only to be carried out by trained
personnel.
Specifications, instructions for use, warranty, performance data, EMC behaviour:
The specifications, instructions for use, warranty conditions, performance data and EMC
behaviour can be found in the user manual.
Maintenance:
Maintenance and safety checks have to be done according to the checklist in the user
manual.
Worn or defective parts must be replaced. However, the pumps do not need any regular
replacement of specific items. Arcomed AG provides service kits and it might be more
efficient to use all parts provided in the kits to avoid additional repairs. It is however not
mandatory to use all parts in the kits.

SH-7000-Chroma-EN-04/17 7
2Setup Mode:
To carry out calibrations and adjustments the pump has to be started in setup mode. In the
following chapter this process is described in detail. For convenience the procedure is
referred to as setup mode (SM) during the remainder of this document.
2.1 Starting the pump in Setup Mode
1. press and hold right down arrow “V” key on the “DATA” window
2. press “ON/OFF” key
3. enter 1111 in the “DATA” window with the arrow “V / Λ” keys
4. confirm with “SELECT”
5. “RATE” and “DATA” window show 0
You have now successfully entered the setup mode of the Volumed® µVP7000 Chroma.
The address number is displayed in the “RATE” window. In the “DATA” window the current
values on the corresponding address is shown. The values can be changed with the arrow
“V / Λ” keys.
Figure: Entering the password for Setup Mode (1111)
Each parameter and its functionality are described in the chapters 3.3 and 3.4.
2.2 Description of pump setup.
The database of the pump consists of approximately 55 addresses. They consist of the
following groups:
Address 0-19 = Basic settings, calibration, apply globally
Address 20-50 = Optional settings, apply per configuration
Basic settings are superior parameters, which define the actual over all calibration of the
device. With the optional settings the LCD contrast or the language etc. can be changed.
Manual changes on the option settings are only possible when address 50 = 0. The
optional setting for each configuration can only be changed with arcomed ag own
PremiumLink™ software. For the usage of PremiumLink™ separate trainings are
mandatory.

SH-7000-Chroma-EN-04/17 8
!!IMPORTANT!!:
To ensure that the basic settings take effect, set address 50 = 0!
Optional settings, Address 31 and 32, have to be programmed with PremiumLink™ SW!
Ensure that after maintenance the configuration on address 50 = 1-8.
Read the values on pump screen.

4Internal Alarms
The Volumed® µVP7000 Chroma continuously monitors the correct functionality of the
pump. For safety reasons the pump will trigger an internal alarm if any discrepancy is
detected. If an internal alarm occurs, the pump will automatically stop and emit a
permanent audible alarm and the alarm pictogram is illuminated. An internal alarm does
not mean that the pump is defect, but it should be carefully checked by the technical staff
before putting it back into operation.
HINT: Take the pump of the mains power. You can switch off the pump after an internal
alarm by pressing the ON/OFF key. If the pump should not power down immediately and
continue the audible alarm, hold the ON/OFF key of 12 seconds to reset it. A reset will not
erase the configuration of the pump. However the current infusion settings might be lost.
In the “Status / Help” menu, which can be accessed with the “SELECT”key, the LCD will
display the error code. In such cases the pump must not be used any more until the cause
has been checked. If the device cannot be repaired the pump should be sent to technical
department or to arcomed ag.
