Alternative solutions must comply with the following
requirements:
f
Electrically isolated power supply unit with a max.
open-circuit voltage of 30 V/DC and a limited
current of max. 8 A.
f
Electrically isolated power supply unit in combina-
tion with fuse as per UL248. This fuse should be
designed for max. 3.3 A and should be integrated
into the 30 V DC voltage section.
In order to avoid EMC interference, the physical
environmental and operating conditions at the
installation site of the device must comply with
the requirements according to the standard
EN 60204-1:2006, section 4.4.2 (EMC).
f
For terminal assignment see Figure 4.
f
For detailed information see the system manual
for the evaluation unit used.
Setup and functional check
Pay attention to the information in the system manual
for the evaluation unit used during setup.
Danger of fatal injuries as a result of faults in
installation and functional check.
f
Before carrying out the functional check,
make sure that there are no persons in the
danger area.
f
Observe the valid accident prevention regula-
tions.
f Mechanical function test
The actuator must slide easily into the recess on
the actuating head. Close the safety guard several
times to check the function.
f Electrical function test
After installation and any fault, the safety function
must be fully checked. Proceed as follows:
1. Switch on operating voltage.
f
The machine must not start automatically.
2. Close all safety guards.
Guard locking by solenoid force: Activate
guard locking.
f
The machine must not start automatically. It
must not be possible to open the safety guard.
3. Enable operation in the control system.
f
It must not be possible to deactivate the guard
locking as long as operation is enabled.
4. Disable operation in the control system and
deactivate guard locking.
f
The guard locking must remain active until there
is no longer any risk of injury.
f
It must not be possible to start the machine as
long as the guard locking is deactivated.
Service and inspection
Warning:
Loss of the safety function because of damage
to the system.
In case of damage, the entire device must be
replaced.
Only accessories or spare parts that can be ordered
from EUCHNER may be replaced.
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
f
Check the switching function (see section Functional
check)
f
Check all additional functions (e.g. escape release,
lockout mechanism, etc.)
f
Check the secure fastening of the devices and the
connections
f
Check for soiling
No servicing is required, repairs to the device are only
allowed to be made by the manufacturer.
Note:
The year of manufacture can be seen in the lower right
corner of the type plate.
Exclusion of liability under the following
circumstances
f
incorrect use
f
non-compliance with safety regulations
f
installation and electrical connection not per-
formed by authorized personnel
f
failure to perform functional checks.
