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 re­quirements, conversion, setting, its safety-related mechanisms, servi-

cing, maintenance and repair must be performed by qualied person­nel 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 acci­dent prevention regulations.

Hydraulic and pneumatic lines should be installed so that they do not
present any risk. There should be no bending (minimum bending ra­dius 50 mm for lines supplied by E+L).

Operating elements that are a potential risk when pressure is redu­ced, e.g. bursting of the hose or motor standstill, should be appropri­ately safeguarded by the user.

Please ensure that:

- electrical components without enclosures such as switch panels
or operating devices are protected according to the locally appli­cable safety regulations, e.g. VDE 0100

- when laying electrical leads the customer shall ensure that the in­sulation is not damaged and that leads are correctly secured and
screened

- controller power is switched on along with the main machine sys­tem 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 qualied persons or suitably in­structed personnel only.

Pneumohydraulic controller HP 036./HP 037.

The HP 03.. controller is used to position actuators in web guiding
systems or in unwinding/rewinding stations. The controller is desig­ned for systems guiding by the web edge with a pneumatic sensor
FL2.. .

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 di󰀨erent electrical versi­ons.

- 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 three­phase 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 di󰀨erent situations is set via a restrictor.

Some of the compressed air is sent to diaphragm D 1 (see pneu­matic system plan on opposite page, at top). A pressure spring works
in the opposite direction to the dia grapm. If the sensor is covered ap­propriately, 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, inuences the diaphragm. The change to the dia­phragm directly a󰀨ects 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
web edge only (automatic) is possible.
