Operating Instructions
Safety Switch STP-TW...AS1 (Twin)
guard locking is closed.
The switch is monitored for a malfunction.
Observe the following if the guard locking solenoid
on a STP-TW3..AS1 spring interlock safety switch
in the operating mode door locking for duration
of the time delay is switched on (released) via the
second release contact of a dual-channel safety
monitor and a PLC:
It is not possible to switch off the guard locking
f
solenoid by means of the monitor alone.
The control system (PLC) must therefore switch off
the guard locking solenoid in the locked position via
AS-Interface output D0 = 0 in order to re-establish
the switch-on conditions for the first OSSD.
The AS-Interface output must be switched on
f
with D0 = 1 so that the guard locking solenoid
can be released by the second safety output of
the monitor.
Status signals (not relevant to safety)
The state of the AS-Interface input bits D0 and D1 for
door monitoring and the AS-Interface input bits D2
and D3 for solenoid monitoring can also be polled
by the control system (PLC) (refer to the operating
instructions for the AS-Interface safety monitor).
LED displays
The AS-Interface bus status is indicated by two LEDs
(Power, Fault).
Two additional LEDs can be connected via the
AS-Interface bus, e.g. to indicate the status signals
(see status signals and technical data).
Function test
WARNING
Fatal injury due to faults during the function test.
Before carrying out the function test, make sure
f
that there are no persons in the danger area.
Observe the valid accident prevention regula-
f
tions.
Check the device for correct function after installa-
tion and after every fault.
Proceed as follows:
Mechanical function test
The actuator must slide easily into the actuating
head. Close the guard several times to check the
function. The function of any manual releases (except
for the auxiliary release) must also be tested.
Electrical function test
1. Switch on operating voltage.
2. Close all guards and activate guard locking.
The machine must not start automatically.
¨
It must not be possible to open the guard.
¨
3. Start the machine function.
It must not be possible to release guard locking
¨
as long as the dangerous machine function is
active.
4. Stop the machine function and release guard
locking.
The guard must remain locked until there is no
¨
longer any risk of injury (e.g. due to movements
with overtravel).
It must not be possible to start the machine
¨
function as long as guard locking is released.
Repeat steps 2 - 4 for each guard.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
If damage or wear is found, the complete switch
f
and actuator assembly must be replaced. Re-
placement of individual parts or assemblies is
not permitted.
Check the device for proper function at regular
f
intervals and after every fault. For informa-
tion about possible time intervals, refer to
EN ISO 14119:2013, section 8.2.
Inspection of the following is necessary to ensure
trouble-free long-term operation:
Correct switching function
f
Secure mounting of all components
f
Damage, heavy contamination, dirt and wear
f
Sealing of cable entry
f
Loose cable connections or plug connectors.
f
Info: The year of manufacture can be seen in the
bottom right corner of the type label.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety regula-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
Notes about
This device is intended to be used with a Class 2
f
power source in accordance with UL1310.
As an alternative an LV/C (Limited Voltage/Current)
power source with the following properties can
be used:
This device shall be used with a suitable isolating
source in conjunction with a fuse in accordance
with UL248. The fuse shall be rated max. 3 A and
be installed in the max. 33.3 V DC power supply
to the device in order to limit the available current
to comply with the UL requirements. Please note
possibly lower connection ratings for your device
(refer to the technical data).
For use and application as per the requirements
f
of a connecting cable listed under the UL
1)
category code CYJV/7 must be used.
1) Note on the scope of the UL approval: The devices have been
tested as per the requirements of UL508 and CSA/C22.2 no.
14 (protection against electric shock and fire).
Declaration of conformity
The product complies with the requirements accord-
ing to Machinery Directive 2006/42/EC.
