1Evaluation unit
2Sensor
3Actuator (transponder)
The T4000 Multi transponder safety switch consists of three components:
•Sensor
The sensor is mounted on the fixed part of the guard and is connected to the eval‐
uation unit.
•Actuator (transponder)
The actuator is mounted on the movable part of the guard.
Each actuator has a unique electronic code.
•Evaluation unit
The evaluation unit must be installed in a control cabinet with an enclosure rating
of at least IP54. Depending on the evaluation unit variant (see "Product variants",
page 11), up to two or up to four sensors can be connected to the evaluation
unit.
Operating principle
The T4000 Multi transponder safety switch monitors movable physical guards:
■Operation of the machine in automatic mode is possible only if the guards are
closed.
■A stop command is triggered if the guard is opened while the machine is running.
The T4000 Multi transponder safety switch is uniquely coded: An actuator must be
taught in at the connected sensors during commissioning.

10 O P E R A T I N G I N S T R U C T I O N S | T4000 Multi 8022726/2019-05-07 | SICK
Subject to change without notice

When a guard is closed, the actuator is moved towards the sensor. The sensor detects
the code of the actuator when it reaches the switch-on distance. If the sensor detects a
taught-in code (valid actuator), the evaluation unit sets the corresponding application
diagnostic output OUT to HIGH.
If valid actuator has been detected for all connected sensors, the system sets the
safety outputs (relay output) to HIGH.
When a guard is opened, the actuator is moved out of the sensor’s response range. The
system sets the safety outputs and the application diagnostic output OUT
01 … 04 assigned to the sensor to LOW.
Additional actuators can be taught in for the connected sensors (e.g. after replacement
of an actuator). Only the most recently taught-in actuator is valid.
3.2 Product characteristics
3.2.1 Product variants
The safety switch is delivered in different variants. You will find an overview of impor‐
tant distinguishing features of the variants in the following.
Sensor
•Sensor with plug connector M8, 3-pin (with latching and screw connection)
•Sensor with permanently connected cable and flying leads (5, 10 or 15 m)
Evaluation unit
•T4000-1RCA02: for connection of up to two sensors
•T4000-1RCA04: for connection of up to four sensors.
Complete overview of all variants: see "Ordering information", page 42.
3.2.2 Sensing face
The sensor has a sensing face, see "Dimensional drawings", page 40.
3.2.3 Fault detection
Any faults that occur, including internal device faults, are detected at the latest with the
next request to close the safe contacts (e.g. at the machine start). The safety switch
then switches to safe state. If a fault is detected, the safety circuit is switched off, the
diagnostic output DIA is set to HIGH and the LED DIA lights up red.
The evaluation unit enters safe status for every detectable fault due to dynamic interro‐
gation of the actuators and the redundant, diverse configuration of the safety electron‐
ics in combination with two safety outputs. The status of the safety outputs is moni‐
tored internally by positively guided N/C contacts (relay output).
3.2.4 Status indicators
The LEDs STATE (green), OUT (yellow ) and DIA (red) indicate the operational status of
the safety switch on the evaluation unit.
Overview of the LED statuses and their meanings: see "LED status indicators",
page 31.
3.2.5 Reset
The T4000 Multi transponder safety switch has a reset function. The function can be
taught in during commissioning.

Subject to change without notice

After the protective device has been tripped, the operator must press a reset pushbut‐
ton to return the protective device to monitoring status. Then, in a second step, the
operator can restart the machine.
3.2.6 External device monitoring (EDM)
The T4000 Multi transponder safety switch has an external device monitoring (EDM)
function. The function can be taught in during commissioning.
External device monitoring (EDM) monitors the status of downstream contactors.
In order to use external device monitoring, positively guided contactors must be used to
switch off the machine. If the auxiliary contacts of the positively guided contactors are
connected to the external device monitoring, the external device monitoring checks
whether the contactors drop out when the safety outputs are switched off.
If the contactors do not drop out, the T4000 Multi transponder safety switch will pre‐
vent the protective device from being reset.

4 Project planning
4.1 Manufacturer of the machine
DANGER
Failure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
bCarry out a risk assessment before using the safety switch.
bDo not tamper with, open, or modify the components of the safety switch.
bDo not repair defective devices – they must be replaced instead.
bMake sure that switch-on commands which bring about a dangerous state of the
machine are not enabled until the protective device is closed.
bMake sure that a stop command is triggered when the protective device is opened
during the dangerous machine state.
bThe safety switches must not be defeated (contacts jumpered), rotated away,
removed, or rendered ineffective in any other way. If necessary, put measures in
place to reduce possibilities for defeat.
4.2 Operating entity of the machine
DANGER
Failure to comply with operating entity’s obligations
Hazard due to lack of effectiveness of the protective device
bModifications to the machine and modifications to the mechanical mounting of
the safety switch necessitate a new risk assessment. The results of this risk
assessment may require the operating entity of the machine to fulfill the manufac‐
turer’s obligations.
bApart from during the procedures described in this document, the components of
the safety switch must not be opened or modified.
bDo not perform repair work on the components. Improper repair of the safety
switch can lead to a loss of the protective function.
bEnsure that there is no bypassing by replacement actuators. Restrict access to
actuators.
4.3 Design
DANGER
Bypassing the protective device
Hazard due to lack of effectiveness of the protective device
1. Avoid incentives to manipulate the safety switch by means of the following mea‐
sure:
°Use permanent mounting methods for actuators (e.g. welding, adhesive
bonding, safety screws or rivets).
2. Observe the design requirements in accordance with ISO 14119 for mounting:
°Reduction of bypass possibilities of an interlocking device
°Mounting of safety switch and actuator
Mounting location
If the mounting location is not specified by the machine documentation, it must be cho‐
sen carefully, see "Mounting", page 20.

Distance
If several safety switches are mounted on the machine, they must be mounted at a min‐
imum distance to one another see "Mounting", page 20.
Alignment
The sensor and actuator must be mounted so that their sensing faces are directly
aligned facing each other, see "Dimensional drawings", page 40.
Actuating direction
The actuator must approach the sensing face of the sensor when the guard is closed.
4.4 Integration into the electrical control
Switch-on commands that put the machine in a dangerous state may only be activated
when the protective device is closed. When the machine goes into a dangerous state, a
stop command must be triggered if the protective device is opened. Depending on the
safety concept, the signal is analyzed by safety relays or a safety controller, for example.
The control that is connected and all devices responsible for safety must comply with
the required performance level and the required category (for example, according to
ISO 13849-1).
4.4.1 Safety outputs
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.
bMake sure that the following control and electrical requirements are met so the
protective function can be fulfilled.
•The output signals of the safety outputs must not be connected to each other.
•The two signals must be processed separately in the machine controller.
•The machine must switch to the safe state at any time if at least one safety output
switches to the OFF state.
•The safety outputs (relay outputs) KA (13/14) and KB (23/24) must be provided
with external fuse protection (use fuse 6 A gG or miniature circuit-breaker 6 A with
characteristic B or C).
•A cross-circuit between safety output KA (13/14) and safety output KB (23/24)
can be detected only by external clocking. A cross-circuit in the cable can be
excluded by protected cable routing.
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.
bMake sure that downstream contactors are monitored (external device monitoring,
EDM).

4.4.2 Application diagnostic output
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state may not be stopped in the event of non-compliance.
Application diagnostic outputs must not be used as safety outputs.
The signal of the 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 guard is opened and closed.

4.4.3 Preventing unexpected startup
DANGER
Hazard due to unexpected starting of the machine
bDo not use the reset function of the T4000 Multi transponder safety switch as a
restart interlock.
bA separate restart interlock must be provided for the machine.
Reset
Either manual or automatic reset can be configured for the T4000 Multi transponder
safety switch.
When a protective device has sent a stop command, the stopped state must be main‐
tained until a reset device is activated and the machine can be restarted in a second
step.
The reset brings the protective device back to the monitoring state after it has sent a
stop command. The reset also quits the start-up or restart interlock of a protective
device, so that the machine can be restarted in a second step.
The reset must only be possible, when all safety functions and protective devices are
functional.
The reset of the protective device must not introduce any movement or dangerous situ‐
ations itself. The machine is only permitted to start after the reset once a separate start
command has been sent.
•Manual resets are performed using a separate, manually operated device, such as
a reset pushbutton.
•Automatic resets by the protective device are only permitted in special cases, if
one of the following conditions is met:
°It must not be possible for people to be in the hazardous area without trigger‐
ing the protective device.
°It must be ensured that no people are in the hazardous area during or after
the reset.
4.4.4 External device monitoring (EDM)
The T4000 Multi transponder safety switch has an external device monitoring function.

Subject to change without notice

The external switching elements (external device monitoring, EDM) must be inspected
in line with the regulations which apply at the place of installation or the required relia‐
bility of the safety function.
NOTE
Monitoring of the series-connected contactors is necessary in order to realize category
4 in accordance with ISO 13849-1.
The external device monitoring (EDM) monitors the status of downstream contactors.
Requirements
Positively guided contactors are used for shutting down the machine.
If the auxiliary contacts of the positively guided contactors are connected to the exter‐
nal device monitoring, the external device monitoring checks whether the contactors
drop out when the safety outputs (relay outputs) are switched off.
Operating principle
If you teach in external device monitoring, the T4000 Multi transponder safety switch
checks the contactors each time the safety outputs are switched off and before the
machine restarts. External device monitoring is then able to detect if one of the contac‐
tor’s contacts is welded, for instance. In this case, the safety outputs remain in the OFF
state.

You must implement external device monitoring electrically so that the two N/C con‐
tacts (k1, k2) close in a positively guided manner when the contactors (K1, K2) reach
their de-energized position once the protective device has responded. 24 V is then
present at the input of external device monitoring. If 24 V is not present when the pro‐
tective device has responded, one of the contactors is defective and external device
monitoring prevents the machine from restarting.

Regular thorough checks serve to investigate the effectiveness of the safety switch and
discover defects resulting from modifications or external influences (such as damage or
manipulation).
The manufacturer and operating entity must define the type and frequency of the thor‐
ough checks on the machine on the basis of the application conditions and the risk
assessment. The process of defining the thorough checks must be documented in a
traceable manner.
4.5.1 Minimum requirements for the regular thorough check
The following thorough checks must be carried out at least once a year:
•Thorough check of the protective function of the safety switch (see "Thorough
check of the safety function", page 33)
•Thorough check of secure mounting of the devices and connections
•Thorough check of the housing, cables and plug connectors for damage
•Thorough check for contamination
•Thorough check of assured switch-off distance Sar
•Thorough check of the safety switch for signs of misuse or manipulation
