Safety Instructions
Only trained professional electricians may
install, startup, modify, and retrofit this
equipment! Disconnect the device / system
from all power sources prior to starting any
work! If installation or system errors occur,
line voltage may be present at the control
circuit in devices without DC isolation!
Observe all electrical safety regulations
issued by the appropriate technical authori-
ties or the trade association. The safety
function can be lost if the device is not
used for the intended purpose. Opening
the housing or any other manipulation will
void the warranty.
Caution!
If the device has been subjected to im-
proper or incorrect use it must no longer be
used, and the guarantee loses its validity.
Impermissible conditions include:
strong mechanical stress, for example
through a fall, or voltages, currents,
temperatures or humidity outside of the
specifications.
Before starting up your machine/plant for
the first time, please be sure to check all
the safety functions according to valid
regulations, and observe the specified test
cycles for safety equipment.
Caution!
Perform the following precautionary steps
prior to installation, assembly, or disas-
sembly:
1.
Disconnect supply voltage to the equip-
ment/system prior to starting any work!
2.
Lockout/tag the equipment/system to
prevent accidental activation!
3.
Confirm that no voltage is present!
4.
Ground the phases and short to ground!
5.
Protect against adjacent live compo-
nents using guards and barriers!
Caution!
Limited contact protection! Protection type
according to EN 60529.
Housing/terminals: IP 40/ IP 20.
Finger-proof acc. to VDE 0660 Part 514.
Description of Device and Function
This device is a two-channel safety switching device for safety applications with self-
monitoring on each ON-OFF cycle. It conforms to EN 60204-1, EN 81-1/2, EN 50156-1
and is equipped with positively driven relays.
After supply voltage has been connected to terminals A1/A2 and the safety inputs
closed, operating the reset button closes the enabling current paths (manual start).
When the safety inputs are opened/de-excited the enabling current paths will open.
Proper Use
The devices are safety switching devices. They must only be used as components of
safety equipment on machines intended to protect persons, material and plant.
Notes
•
The Performance Level (PL) and safety category in accordance with EN ISO 13849-1
depends on the external wiring, the application case, the choice of control station and
how this is physically arranged on the machine.
•
The user must carry out a risk assessment in accordance with ISO 14121-1.
•
The entire system/machine must undergo validation in accordance with the applicable
standards on the basis of this.
•
In order for the specified Performance Level (PL) to be achieved, an average annual
number of switching cycles must not be exceeded (see EN ISO 13849-1, C.2.4 and
Tab. K.1), taking into account the prevailing device load (see EN ISO 13849-1, Tab.
C.1) and the application case. Assuming that the B10d value for the maximum load is
400,000, this results in a maximum cycle number of 400,000 / 0.1 x 30 = 133,333
switching cycles/year.
•
The supply input A1 also serves as a control input. This may lead to short disruptions
or a lowering below the operating voltage in order to switch to the release path.
•
The indicated times must be observed when the device is operated, otherwise the
device could lock. Locking can be cancelled by opening the safety inputs properly.
The MSI-SR-LC21M-xx types are especially suitable for use in applications with fast
and short bounce operations, since these devices prevent locking.
•
MSI-SR-CM expansion devices or external contactors with positively driven contacts
can be used to duplicate the enabling current paths.
•
The devices are equipped with overload protection (for short-circuit). After the
malfunction has been dealt with, the device is operational again in approx. 3 s.
•
Control output S11 is exclusively for connecting control devices as defined in the
operating instructions and not for connecting external consumers such as lamps,
relays or contactors.
•
With the application in furnaces output circuits are to be secured with 0.6 * I
n
.
Please observe instructions from safety authorities and national regulations!
