1.1 Approved applications
1.2 Operating instructions
1.3 Mounting
The E+L controller HP 03.. must only be used to operate a hydraulic
positioning device.
Only use the controller
- if it is in perfect condition technically
- in accordance with its intended usage
- with an awareness of safety and risk factors and in compliance
with the operating instructions.
Any jobs regarding controller operation, gearing to production re-
quirements, conversion, setting, its safety-related mechanisms, servi-
cing, maintenance and repair must be performed by qualied person-
nel only. Please observe the switching on/o procedure laid out in the
operating instructions.
Look after these operating instructions carefully and make sure they
are available to personnel at all times.
The operating instructions are part of the package and should be
read carefully prior to mounting, operation and maintenance work.
Please observe the locally applicable and customary safety and acci-
dent prevention regulations.
Hydraulic and pneumatic lines should be installed so that they do not
present any risk. There should be no bending (minimum bending ra-
dius 50 mm for lines supplied by E+L).
Operating elements that are a potential risk when pressure is redu-
ced, e.g. bursting of the hose or motor standstill, should be appropri-
ately safeguarded by the user.
Please ensure that:
- electrical components without enclosures such as switch panels
or operating devices are protected according to the locally appli-
cable safety regulations, e.g. VDE 0100
- when laying electrical leads the customer shall ensure that the in-
sulation is not damaged and that leads are correctly secured and
screened
- controller power is switched on along with the main machine sys-
tem switch
- the controller is integrated into the machine control in such a way
as to prevent it starting up independently after a machine standstill
or an emergency OFF device reset.
The controller should be operated by qualied persons or suitably in-
structed personnel only.

2.3 Mode of operation
Motor protec-
tion switch
Contactor
Fuses
Switch panel SE 12521
Connection terminals
The HP 03.. controller is available in three dierent electrical versi-
ons.
- Switch panel SE 12521 with motor protection switch, three-phase
a.c. motor contactor and connection terminals for the valve wiring.
- Terminal box SZ 0921 with connecting terminals only for the three-
phase a.c. motor and valve wiring.
- No electrical wiring.
To generate the air required for sensing, ambient air is drawn into the
side channel compressor and fed to connection S 1 of the pneumatic
sensor. The level of the probing air pressure and thus the control
sensitivity for adjustment to dierent situations is set via a restrictor.
Some of the compressed air is sent to diaphragm D 1 (see pneu-
matic system plan on opposite page, at top). A pressure spring works
in the opposite direction to the diagrapm. If the sensor is covered ap-
propriately, the diaphragm is maintained in the center and the system
in a zero position.
If the web moves away from the zero position, it changes the air cur-
rent which, in turn, inuences the diaphragm. The change to the dia-
phragm directly aects the servo-valve controlling the uid ow. The
uid ow changes the location of the positioning cylinder until the
web returns to its zero position.

On the basic model HP 03.. without valve assembly, guiding by the

4. Mounting
Controller HP 03.. should be mounted so that the air hoses and hy-
draulic lines to the sensor, return-to-center switch and positioning
cylinder are kept as short and straight as possible and are laid accor-
ding to the connection diagrams. The minimum bending radius is 50
mm (for air and hydraulic lines). Please ensure easy access to the
controller for operating and maintenance purposes.
Controller HP 03.. must be mounted a little higher than the positio-
ning cylinder to ensure the self-venting of the system.

The switch panel or terminal box can be mounted in three positions
(see g. below).
When the web passes through the air sensor on the horizontal, sen-
sor connection S 1 should be located underneath the web (see g.
on left). This protects the air sensor from soiling.
The pneumatic sensor should be connected as follows.
Connect S 1.1 on controller to sensor via S 1.
Connect S 2.1 on controller to sensor via S 2.
The air lines to the sensor must be of the same length and not ex-
ceed 3 m. The line to the pneumatic return-to-center switch must not
exceed 6 m. Narrowing of cross- sections and narrow hose elbows
are not permissible due to the danger of rupture. For temperatures
over 70 °C, silicon hoses should be used for the air lines and copper
pipes for the hydraulic lines.
The plastic tubes supplied (6 mm inner diameter, 10 mm outer dia-
meter) should be used for the hydraulic lines. When using steel pipes
(10 mm x 1 mm) these must be cut to size using a pipe cutter. The
pipes must be cleaned prior to installation. The hydraulic lines must
securely xed.

Once the uid ller conver has been removed, the hydraulic uid
should be poured in using a funnel and lter paper. the uid leven
must not rise above the halfway mark on the uid inspection window.
The direction of rotation can be checked by briey applying voltage
to the three phase a.c. motor. The three phase a.c. motor must turn
to the right. An additional check is provided by the pressure gauge, if
the direction of rotation is wrong, no pressure will be built up. The di-
rection of rotation can be reversed by swapping over the two phases
in the connection lead.
6. Commissioning
Check the direction of the positioning cylinder travel when the three-
phase a.c. motor is switched on. To do so, select the guiding by web
edge mode (automatic).
The positioning cylinder or device must move the web away from the
sensor when the sensor jets are covered (see g. on opposite page).
When the air sensor is uncovered, the positioning cylinder should
move towards the air sensor. If the reverse is the case, hydraulic
connections A and B must be swapped.
The hydraulic lines may also be under pressure when the
systemisswitchedo.Whenthehydrauliclinesareopened,
power elements may be activated.
