Description of function
Peristaltic pump principle The EIP 2 (Erbe Irrigation Pump) is a peristaltic pump. This operating prin-
ciple is based on pressing or squeezing a flexible pump hose at one or
more points and on movement of the squeezed point in the desired direc
tion of liquid flow. For this reason peristaltic pumps are sometimes referred to as peristaltic squeeze pumps. Movement of the squeezed point is
accomplished with the aid of a pump rotor that has rollers around its pe
rimeter. Flow is determined by rotor speed (speed of motion of the
squeezed point) and internal cross-section of the hose.
Advantages of peristaltic pumps With peristaltic pumps the medium and the pump do not come into contact
with one another. Therefore peristaltic pumps are particularly suited for
metering a very wide range of media. As opposed to other types of pump
like diaphragm pumps, with peristaltic pumps it is very easy to adapt the
material of the pump hose, or components coming into contact with the
medium, to the product being pumped. A pump hose is selected and used
that is chemically suited for the product being pumped ("milled hose").

Description of the various assemblies
Line input
The EIP 2 can be operated on line voltages of 230 V, 120 V, or 100 V. First
of all the appropriate figure must be set, ±10
%, in the window of the volt-
age selector switch on the main board.
Tra ns form er
The transformer converts the line voltage input from 230 V ±10 % or
120
V ±10 % to 2 x 9 V. The maximum available current is 1.33 A.
For operation of the EIP 2 at a line voltage of 100 V ±10 % a different type
of transformer must be used. That transformer converts the line voltage
input to 2 x 12
V um. The maximum available current is 1.25 A.
Bridge-connected rectifier
The bridge-connected rectifier provides the operating voltage of 24 V.
Switching controller
The switching controller provides an operating voltage of 5 V.
Monitoring the motor control
This circuit is designed to prevent a faulty motor control from leading to
uncontrolled pump activity. The operating voltage of 24
V is only supplied
to the motor control if the microcontroller releases it by actuating the
monitoring circuit accordingly.
Motor control
The motor control is regulated by the microcontroller via a PWM signal at
a level of 5
V. The output voltage of the motor control is increased to a
maximum of 24
V depending on the PWM signal.
CAUTION! An incorrect setting can cause damage to the unit.

Microcontroller
The Type PIC18F258 microcontroller handles several tasks:
• Evaluation of current and voltage measurements of motor monitoring
• Adjustment of motor control to the current and voltage levels via a
PWM signal
• Checking of any activations by pushbutton or footswitch
• Updating of display on the control panel
• Communication via a CAN interface with the VIO electrosurgical unit
(only on units with ECB socket, ECB = Erbe Communication Bus).
CAN module (optional)
The CAN module enables communication between EIP 2 and the VIO electrosurgical unit.
Footswitch
The pump can be activated with the EIP 2 footswitch.
Control panel
The control panel makes it possible for the user to perform settings on the
EIP
2.
Three so-called quick activation buttons enable direct adjustment of the
setting, which is otherwise performed using the Up and Down buttons. The
pump can be started with the activation button.
The display section on the control panel is comprised of three 7-segment
displays, which are updated constantly by the microcontroller.
Motor
The motor is a DC motor with a nominal voltage of 24 V and a nominal current of 1.1 A.
The motor has a flanged gear unit, via which the pump head is driven.

Test intervals
ATTENTION! Adjustments, tests, modifications, maintenance and repair work may
only be performed by Erbe or persons trained by Erbe. If the work is not
performed by trained persons, Erbe accepts no liability and warranty
rights become void.
It is recommended that the technical safety check also be performed by
Erbe or persons trained by Erbe.
IMPORTANT! The safety check is a preventive measure in which there is examined
whether the equipment is safe and ready for operation. In order to per
form the tests the relevant specifications and regulations of the particular country must be observed.
IMPORTANT! A technical safety check must be performed every time after mainte-
nance, but at least once per year.

Technical safety check
For simplification the device to be tested is referred to below as the "test
specimen".
Important information
WARNING! For safety reasons (personnel protection) the test specimen should
generally be operated by a suitable isolating transformer.
An exceptional case is the tests for grounded conductor resistance,
ground leakage current, and patient leakage current, in which the test
specimen is supplied with current via the safety tester.
ATTENTION! In the event of a fault occurring in the test specimen or individual com-
ponents during the technical safety check the test steps taken so far no
longer apply.
Remedy the defect and repeat the technical safety check from the
beginning.
IMPORTANT! It is assumed that the user knows how to operate the test specimen,
the test equipment, the measuring equipment, and auxiliary test equip
ment. The test instructions only apply in conjunction with the relevant
test steps.
IMPORTANT! Test equipment, measuring equipment, and auxiliary test equipment
(cables, test boxes, etc.) are listed separately at the beginning of each
test unit. Where Erbe article numbers are specified, only original Erbe
test equipment, measuring equipment, and auxiliary test equipment
may be used.
IMPORTANT! The test report for the technical safety check can be requested from
Erbe Technical Service Tübingen. For the address see address sheet on
last page.

pump motor using the activation button. Activation should stop within
a time window of 18 s to 22 s.
2. Test st ep 2 : Connect up footswitch. Repeat test step 1, now activating
the test specimen with the footswitch. Activation should stop within a
time window of 18 s to 22 s.
Check the automatic
pressure control
IMPORTANT! For units from software version 1.1.0 onwards, the automat-
ic pressure control can be optionally activated or deactivated (see service
program S5). For this test, the automatic pressure control must be activat
-
ed.
1. Insert tube and fill with irrigation liquid (water).
2. To simulate a blockage, clamp the tube at the distal end.
3. Set pump flow to 100 %.
4. Activate pump motor using activation button (or footswitch) and keep
it activated. The test specicmen should reduce flow very audibly.
5. Undo the clamp on the tube. The test specicmen should increase flow
very audibly back to set pump flow.
