- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Service, maintenance, repair
=
DANGER
Live parts.
Electric shock hazard!
Open device only
while it is in zero potential state. Do not repair de-
fective or damaged devices. Replace them.
=
DANGER
Explosive atmosphere.
Explosion hazard! Risk of
burns!
Observe maximum switching cycles. Do not
rebuild or modify the device in any way.
NOTICE
In all operational life phases of the device, meas-
ures that are constructively and organizationally
suitable for protection against manipulation or
against circumvention of the safety device, e.g. by
using a spare actuator.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check switching function.
2. Check for tight installation of the switch and actuator.
3. Check for alignment of solenoid interlock and actuator.
4. Removal of dirt.
5. Screw and close cover correctly, tightening torque 0.5 … 0.6 Nm.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
N.B.
Do not use the device as a mechanical endstop. Any mounting position
is possible. It should be selected in such a way that no coarse dirt can
fall into the used slot. The unused slots should be protected with the
optional slotcaps. Reconstruction and alterations at the device - which
might affect the explosion protection - are not allowed. Furthermore,
EN 60079-14 has to be applied for the installation of electrical equip-
ment in hazardous areas. The described products were developed in
order to assume safety functions as part of an entire plant or machine.
A complete safety system normally covers sensors, monitoring mod-
ules, indicator switches and concepts for safe disconnection. There-
fore, a validation according to EN ISO 13849-2 or EN 62061 is neces-
sary.
Furthermore, the Performance Level according to EN ISO 13849-
1 and SIL CL Level according to EN 62061 can be lower than the single
level because of the combination of several safety components and
other safety-related devices, e.g. by serial connection of sensors.
It is
the responsibility of the manufacturer of a plant or machine to guaran-
tee the correct general function. Subject to technical modifications.
=
DANGER
Leakage lowers the IP degree of protection.
Explosion hazard!
Risk of burns!
Tighten the
cover appropriately. Oberserve tightening torque
0.5 - 0.6 Nm. Install cable gland correctly. Check
cable gland for tightness (min. IP64) where it meets
the cable.
Single-wires must be stripped at least 5 mm, multi-wires must be
stripped at least 5 mm and equipped with 5 mm long conductor fer-
rules. Mount the solenoid interlock and actuator on an even surface.
The solenoid interlock Ex STM 295 has to be fixed with 3 screws for
which 3 fixing holes are provided. The electrical connection may only
be carried out by authorised personnel. They must take care that the
accessibilty of actuators or spare actuators is prevented because of
the danger of manipulation. Ensure that the device cannot be moved
from its position. Ensure this in case of failure, too. For protection
against manipulation use oneway safety screws. With other fastening,
e.g. riveting or welding, ensure that the immersion depth of the coded
actuating bracket does not change. Operational use of the auxiliary
unlocking device must be eliminated by appropriate measures.
When
mounting the actuator and switch, observe the requirements of EN
ISO 14119, especially the sections 5.1 to 5.4!
Observe the instructions
in the standards EN ISO 12100 and EN ISO 14120.
Application and operation
=
DANGER
Live parts.
Electric shock hazard!
Protective cover
over contacts must be intact.
=
DANGER
In case of overloaded contacts too high operation
temperatures.
Explosion hazard! Risk of burns!
For
short-circuit protection use appropriate fuse size.
- Use device only within the permitted electrical load limits (see
technical data).
- Use device only within the permitted ambient temperature range
(see product label and technical data).
Cleaning
=
DANGER
Live parts.
Electric shock hazard!
When cleaning:
observe degree of protection IP64.
- Use a damp cloth to clean devices in hazardous areas. This prevents
electrostatic charge.
