Operating and installation instructions
Thrust actuator ARI-PREMIO
5.0 Installation
5.1 General installation data
- In addition to general installation guidelines, the following points are required to be
observed:
- Planners / construction firms and operators are responsible for positioning and installing
the products.
Where relay points and electronic load relays are particularly sensitive a coil should be
connected in series additionally to each relay point.
- Contactors of 16A and upwards do not need a safety circuit.
- Check thrust actuator for damage prior to fitting.
Damaged parts must be replaced by original spares.
- Existing operating instructions for valve.
- Complete valve with crossarm.
- Valve cone approximately in mid lift position - on no account supported inside a seat!
- Electrical installation in accordance with current regional regulations.
- Conductor cross-section selected to correspond to the given drive power and existing line
length.
ATTENTION !
- Work on electrical systems or equipment must only be carried out by qualified
electricians or by trained individuals under the guidance and supervision of a
qualified electrician in compliance with regional electrical safety requirements
and regulations.
- Valve mountings such as drives, handwheels, hoods must not be used to take
external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
Non-compliance may lead to death, injury or damage to property due to
persons falling or parts being dropped.
- Actuator components which rotate or move during operation are coloured red.
Crushing and injury hazard!
ATTENTION !
- A voltage is induced in the thrust actuator motor. This induction voltage may be
higher than the operating voltage.
- For this reason relays and electronic load relays for thrust actuator control
require a protective circuit. The contacts of unprotected relays may stick after a
while.
- This may result in reversed directions of rotation or defective switch-off
Recommended safety circuit for relays and electronic load relays:
Connect a varistor or RC module parallel to each relay point.
Varistor
S10K385 to S10K460
RC module 100 Ohm / 100nF
Recommended coil:
Toroidal coil
2mH / 2A
