Actuating head

4
The safety locking device is an interlocking device with a locking function. The safety
locking device consists of a safety switch and a coded actuator. The actuator has a high
coding level (uniquely coded).
Function
When the protective device is closed, the actuator is inserted into the actuating head of
the safety switch. In doing so, the locking pin is pressed downward by the actuator. If
the actuator reaches the end position, the locking pin moves into the provided hole of
the actuator.
Further functioning depends on whether the safety locking device is based on the
power to release or the power to lock principle.
In the power to release principle, the inserted actuator is immediately blocked and
•
the locking device is locked (to unlock the locking device, the locking solenoid
must be energized).
In the power to lock principle, the locking solenoid must be energized in order to
•
lock the locking device. If the locking solenoid is not energized, the actuator is only
held in position by retaining force (spring force). The actuator can be pulled out
again by overpowering the retaining force.
Complementary information
The code of the actuator is read out and evaluated using transponder technology.
•
•
If the code is valid, the door application diagnostic output (Out AUX DOOR)
switches to the ON state.
If the locking device is locked, the safe output signal switching devices (OSSD) are
switched to the ON state. In addition, the locking function application diagnostic
output (Out AUX LOCK) switches to the ON state.

If the locking device is locked, the actuator cannot be removed from the actuating
•
head.
The locking device can only be locked when the protective device is closed (pre‐
•
vention of incorrect closing).

3.2.2OSSD
Output signal switching device: signal output for the protective device, which is used for
stopping the dangerous movement.
An OSSD is a safety switching output. The functionality of each OSSD is tested periodi‐
cally. OSSDs are always connected in pairs and must undergo dual-channel analysis for
safety reasons. An OSSD pair is formed from 2 OSSDs that are connected and analyzed
together.
The pushbuttons contain single-channel normally open contacts which can be
used to trigger control signals.
LEDs are located in the pushbuttons which can be controlled, e.g. to signal opera‐
tional statuses.
The pushbuttons can be assigned colors using cover caps.

4.4Integration in the electrical control system
Switch-on commands that put the machine in a dangerous state may only be activated
when the protective device is closed and the locking device is locked. The locking
device may only be unlocked when the dangerous state has ended. Depending on the
safety concept, the signal is analyzed by safety relays or a safety controller, for example.
The connected controller and all devices responsible for safety must comply with the
required performance level and the required category (for example according to
ISO 13849-1).
The overall concept of the control system in which the safety locking device is inte‐
grated must be validated in accordance with ISO 13849-2.
4.4.1Locking function
Prerequisites
A shared power supply is used for the control system and for the locking solenoids
•
of the safety locking device.
A clocked power supply is not used.
•
When connecting the locking solenoids to the output of a controller, this output
•
must supply sufficient current.
The activation of the locking solenoids of the safety locking device changes depending
on the locking principle.

Power to release principle
Locking the locking device: Close the protective device, no voltage on the magnet
•
Unlocking the locking device: Apply voltage to magnet
•
If voltage is interrupted at the magnet, the locking device remains locked and the pro‐
tective device cannot be opened immediately.

WARNING
The locking device locks even when voltage is not present
People could get trapped!
If people are in the hazardous area, do not close the protective device even if volt‐
b
age is not present.
Or:
Use the variant with an escape release.
b
Power to lock principle
Locking the locking device: Apply voltage to magnet
•
Unlocking the locking device: Disconnect voltage from magnet
•
If voltage is disconnected at the magnet, the locking device is unlocked and the protec‐
tive device can be opened immediately.
DANGER
Hazard due to lack of effectiveness of the protective device
In the event of a voltage drop, the safety locking device unlocks regardless of whether
the dangerous state of the machine has ended.
Assess the risk of accident. Use for protecting people requires correct project plan‐
b
ning.
Activating the locking function
For single-channel activation of the locking function, the controller and the safety lock‐
ing device must have the same ground.
For dual-channel activation of the locking function, clock pulses are tolerated up to a
max. length of 5 ms. If possible, switch off the clocking of outputs in the control system.
NOTICE
The locking solenoid of the TR110 Lock safety locking device is controlled exter‐
•
nally (no control function within the device). Therefore, the TR110 Lock safety lock‐
ing device does not have any characteristic safety values for controlling the locking
function.
The safety level for controlling the locking function is determined exclusively by
•
external control (e.g. by the PFHd of an external standstill monitor).
Types for series connection of OSSDs have a separate pin MAG 0 V DC in order to apply
0 V to the locking solenoids (see "Device connection", page 29). In the other types,
the 0 V connection of the locking solenoid is connected using the 0 V connection of the
safety locking device.

protective function can be fulfilled.
The output signals from an OSSD pair must not be connected to each other.
•
In the machine controller, both signals from an OSSD pair must be processed sep‐
•
arately.

Prevent the formation of a potential difference between the load and the protec‐
•
tive device. If you connect loads to the OSSDs (safety outputs) that then also
switch if controlled with negative voltage (e.g. electro-mechanical contactor with‐
out reverse polarity protection diode), you must connect the 0 V connections of
these loads and those of the corresponding protective device individually and
directly to the same 0 V terminal strip. In the event of a fault, this is the only way to
ensure that there can be no potential difference between the 0 V connections of
the loads and those of the corresponding protective device.
Figure 12: No potential difference between load and protective device
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
Downstream contactors must be positively guided and monitored depending on applic‐
able national regulations or required reliability of the safety function.
Make sure that downstream contactors are monitored (external device monitoring,
b
EDM).
The OSSDs are short-circuit protected to 24 V DC and 0 V. If the safety locking device is
locked, the OSSDs signal the ON state with the HIGH signal level (non-isolated). If the
safety locking device is unlocked or there is a device fault, the OSSDs signal the OFF
state with the LOW signal level.
Do not use a control system with clocking or switch off the clocking function of the con‐
trol system. The device generates its own test pulses at the OSSDs. A downstream con‐
troller must tolerate these test pulses, which can have a length of up to 1 ms. The test
pulses are also output when the OSSDs are switched off. Depending on the sluggish‐
ness of the downstream device (controller, relay, etc.), this can lead to short switching
processes.
For inductive loads, the OSSDs must be protected with a freewheeling diode. RC sup‐
pressors must not be used:
4.4.3Application diagnostic outputs
Door application diagnostic output (Out AUX DOOR)
The signal of the door application diagnostic output changes as soon as the actuator is
moved into or leaves the response range of the safety switch. In other words, the output
signal changes when the protective device is opened and closed. This is not a safety
output.

safety locking device.
There must not be any clocked controller signals at inputs In 1 and In 2.
•
The maximum number of safety locking devices depends on the following factors:
Applied supply voltage
•
Length of cables used
•
Cable cross-section of cables used
•
Load current
•
The voltage drop in the safe series connection has to be checked so that the defined
minimum voltage is still applied to the last safety locking device.
The number of safety locking devices in a safe series connection influences the
response time of the system (see table 17, page 45).
The safe series connection can be implemented using special T-connectors and an end
connector (see "Connection of a safe series connection", page 32).
4.4.6Protection of the voltage supply
The voltage supply must be provided with fuse protection depending on the number of
safety locking devices and the required current for the outputs.

Testing plan
The safety locking device must be tested by appropriately qualified safety personnel
when commissioning, after modifications, and at regular intervals.
The regular thorough checks serve to investigate the effectiveness of the safety locking
device and discover defects because of modifications or external influences (such as
damage or tampering).
The manufacturer and user must define the type and frequency of the thorough checks
on the machine on the basis of the application conditions and the risk assessment.
Determination of the thorough checks must be documented in a traceable manner.

6.4Connection of a safe series connection
Overview
A maximum of 20 devices can be activated in series. The safe series connection can be
implemented using special T-connectors and an end connector. The safe evaluation
unit switches off the machine if a protective device is opened or a fault occurs at a
safety locking device.
Important information

32
NOTE
The locking device control (MAG 0 V DC), the application diagnostic outputs door
•
(Out AUX DOOR) and error application diagnostic outputs have to be wired sepa‐
rately.
In the case of safety locking devices cascaded with T-connectors, the locking
•
device application diagnostic output (Out AUX LOCK) cannot be evaluated.
Mount the connecting cable so that individual T-connectors (and thus a safety
•
locking device) cannot be easily jumpered.

7Commissioning
7.1Switching on
The device initializes after it is switched on. The OSSDs are in the OFF state during this
and the STATE LED flashes green at 5 Hz.
7.2Teach-in
7.2.1Safety
DANGER
Bypassing the protective device
The dangerous state may not be stopped in the event of non-compliance.
Document teaching-in of an actuator.
b
During regular thorough checks, make sure that the taught-in actuator is still being
b
used.
An actuator must be taught-in during commissioning. Only the most recently taught-in
actuator is valid.
COMMISSIONING 7
During a teach-in operation, the OSSDs are in the OFF state, i.e. the system is in a safe
state.
7.2.2Teaching-in the first actuator in delivery condition
Important information
NOTE
Safety locking devices switched on in delivery condition have a teach-in readiness with
no time limitation.
NOTE
The teach-in process is invalid if canceled, e.g. by interruption of the voltage supply or
removal of the actuator.
Then the TR110 Lock safety locking device enters the safe error state, the DIA LED
lights up red, the STATE LED flashes (see "System status", page 42).
Approach
1.Apply the supply voltage to the safety switch.
✓
The STATE LED flashes 3 times repeatedly.
2.Insert the actuator into the actuating head (close the protective device).
✓
The teach-in process starts, the STATE LED flashes at approx. 1 Hz.
The teach-in process is completed after about 30 seconds. The STATE and DIA
LEDs flash in alternation.
3.Switch off the supply voltage at the safety switch for at least 3 seconds and then
switch it back on.
✓
The code for the actuator that was just taught-in is enabled in the safety switch.
4.Check the effectiveness of the protective device.

7 COMMISSIONING
7.2.3Teaching-in the new actuator
Overview
The TR110 Lock safety locking device can be operated only with the actuator that was
last taught-in.
Important information
NOTE
Safety locking devices with an actuator that has already been taught-in have a teach-in
readiness of approx. 3 minutes after being switched on.
NOTE
If the safety switch detects an actuator that has already been taught-in, then the
•
teach-in process is canceled and the safety switch returns to normal mode.
If the safety switch detects a blocked code of a direct predecessor actuator, then
•
the teach-in process is canceled and the code of the previous actuator remains
active. The safety switch goes into an error state (see "System status", page 42).
Approach
1.Apply the supply voltage to the safety switch.
✓
The STATE LED flashes 3 times repeatedly.
2.Insert the actuator into the actuating head within 3 minutes.
3.The teach-in process starts, the STATE LED flashes at approx. 1 Hz.
✓
The teach-in process is completed after about 30 seconds. The STATE and DIA
LEDs flash in alternation.
4.Switch off the supply voltage at the safety switch for at least 3 seconds and then
switch it back on.
✓
This activates the new code and deactivates the old code.
5.Check the effectiveness of the protective device.
Complementary information
When a new actuator is taught-in, the safety switch blocks the code of the last actuator.
The latter cannot be taught-in again immediately when a new teach-in operation is per‐
formed. The blocked code is released again in the safety switch only after a third code
has been taught-in.
7.2.4Teaching-in the actuator in safe series connection
Important information
NOTE
It is recommended to teach in the actuators not in the safe series connection, but indi‐
vidually.
36
Prerequisites
If the actuators need to be taught-in in a safe series connection, then it has to be possi‐
ble to switch from 0 V DC to 24 V DC at the RST inputs of the safety switches.
