Operating Instructions for
the CD01-PA Valve System
Preamble
To ensure function and your own safety, carefully read the
enclosed operating instructions before beginning
installation. Contact AVENTICS GmbH if you have any
further questions.
General information on explosion
protection
Numerous pneumatic functions can be implemented with
the modular CD01-PA valve system. Valve units can be
created that are actuated via a bus link or individual
connection. As a result, the CD01-PA system is electrical
equipment.
The valve systems may only be used in accordance with
the specifications outlined in the technical documentation
from AVENTICS GmbH and the information on the product
rating plate. They correspond to the valid standards and
directives and fulfill the requirements in ATEX directive
2014/34/EU. The installation regulations (e.g. EN 60079-
14) for systems in explosive areas must be observed.
The valve systems can be used as follows:
W
In zone 2 (gas-ex, category 3G) in explosion groups IIA
and IIB
In the Ex area, 135°C is the reference temperature for
determining the temperature class (T4) and for further
considerations with respect to the safety distance from
the smoldering temperature.
W
The permissible ambient temperature range is listed in
section "Definition of types" of this chapter.
General requirements
a) The manufacturer is not liable for damages in the
case of non-compliance with these instructions or
improper interventions in the device. Furthermore,
the warranty for appliances and accessory parts
will no longer apply.
b) Observe the information in these instructions, as
well as the operating conditions and permissible
values stated on the labels/rating plates of the
respective devices.
c) Observe the general technical rules for the selection
and operation of devices.
d) Take suitable measures to prevent unintended
activation or impermissible interference.
e) The valve systems are only permitted for
appropriate and intended use in normal industrial
settings. In the case of violation, all manufacturer
liability and warranty claims will no longer apply!
f) Ensure that the device is only fitted with ignition
protection complying with the respective zones!
g) All connected electrical devices must be suitable for
their respective functions.
h) The operator must provide sufficient lightning
protection in accordance with local regulations.
i) Be aware of electrostatic when assembling the
valve system.
j) Make sure that no falling objects can hit the valve
system.
k) Protect light alloy housing parts from external
impact energy.
l) The following applies in ATEX areas requiring category
3 equipment: It must be installed in a housing that
corresponds to the requirements for impacts in
accordance with EN 60079-15 (gas explosion
protection) or EN 61241-0 and EN 61241-1 (dust
explosion protection).
m) These devices are "low-energy instruments and
devices" in accordance with paragraph 13 of
EN 60079-15. The requirements in sub-section c)
(transient limitation to 40% above the nominal
voltage) must be observed during installation.
Rating plate presentation
See "Identification on the rating plate" in chapter "2 Notes
on Safety".
Commissioning, installation
Install the valve systems in a superior system. The required
cleaning intervals for the equipment (dust deposits) depend
on the IP protection class. Ensure that the device is only fitted
with ignition protection complying with the respective zones/
categories! Always observe the nationally valid installation
guidelines (e.g. EN 60079-14). Other important facts:
a) The devices are designed for protection class IP54
and may require further protection if used under
more adverse ambient conditions. See also sub-
section l) in section "General information on
explosion protection".
b) Note the declaration of conformity and the special
conditions listed therein.
c) To ensure explosion protection, associated
electrical and mechanical equipment must
correspond to the requirements of the applicable
zones on site and must be checked separately by
the person installing the machine.
d) The device may only be used as intended.
e) Electrostatic charges and/or insulated metal parts
must be avoided. Only clean with a damp cloth!
f) If located in an explosive area, tight parts (e.g. due to
frost or corrosion) may not be removed violently.
g) Protect against unauthorized opening and attach a
sign stating "Do not disconnect under power".
h) Tighten the nuts on the connection plug with a
torque of at least 0.6 Nm.
i) If vibrations occur during operation which could
loosen the plugs, secure them with threadlocker. A
separation force of at least 0.6–2.5 Nm must be
achieved on an equivalent M12 thread.
