5.3. Safe outputs O0 to O3
Safety-related outputs O0 to O3 are designed to act as digital semiconductor outputs for 24 V DC/2 A
(total current).
The outputs are controlled in accordance with the configured safety logic. The safe outputs are linked to
the safety logic that controls them in the connection editor of the SAFECONF configuration software. For
additional information, please refer to the user manual.
5.4. Ground switching outputs O0- and O1-
Ground switching outputs O0- and O1- increase cross circuit protection for the safety system. For
example, these outputs can be used to disconnect a contactor connected to the PSR-TRISAFE-S safety
module via both the output and ground.
The following output combinations can be used for ground switching:
O0/O0- and O1/O1-.
5.5. Monitoring outputs M0 to M3
The non-safety-related monitoring outputs M0, M1, M2, and M3 are designed to act as semiconductor
outputs for 24 V DC/100 mA.
You can use these monitoring outputs, for example, to control a standard PLC or a detector unit
(e.g., a signal lamp). As with the safe inputs and outputs, the monitoring outputs are linked in the
connection editor of SAFECONF.
5.6. Test pulse outputs T0 and T1
The test pulses output at outputs T0 and T1 are used for cross-circuit detection at the inputs. There are
two of each output. The output test pulses T0 and T1 are asynchronous to each other, i.e., T0 is not equal
to T1. Cross-circuit detection can occur between both T0 and T1 and between a test pulse and 24 V.
Cross-circuit detection can only be performed if the safe inputs involved are configured accordingly using
the device parameterization editor (part of the hardware editor in SAFECONF).
6. Operating/Indication elements
LEDs indicate the operating states.
Symbol Description
LED OFF
LED is ON
LED is flashing slowly or quickly
6.1. Status LEDs
The device's operating state can be determined from the
four status LEDs at the front.
The LEDs are as follows (from left to right):
PWR: (green) Indicator for the power supply of the controller
DATA: (green) Indicator for communication with extension devices (with/without TBUS)
ERR: (red) Error display
CONF: (green) Indicator for the configuration status and communication via the
USB interface/IFS-CONFSTICK

6.2. LEDs for safe signal inputs/outputs
The state at each of the 20 safe inputs and 4 safe outputs is indicated by an LED on the front plate of the
device.

For each input
"I0" to "I19"
For each output
"O0" to "O3"
CONF Meaning
Device is switched off:
No power supply at A1 and A2
Initialization phase after switching on
(lasts 4 s maximum)
: Acknowledgment of new configuration required after
downloading: Press the CONFIRM button on the device.
slow
Acknowledgment of a new configuration
:
(transfer via IFS-CONFSTICK)
fast
(see below for confirmation sequence)
: Change of extension devices; acknowledgement required;
press the CONFIRM button on the device.
slow
Normal operation with no extension devices connected
(TBUS communication)
Normal operation with extension devices connected
(TBUS communication)
Restricted operation with errors in at least one IO
-> Resolve error; deactivate IO;
press the CONFIRM button on the device to reset the error
message.
No configuration data on the IFS-CONFSTICK -> Load project
with SAFECONF.
IFS-CONFSTICK not present -> Insert IFS-CONFSTICK and
introduce power supply.
Fatal error!
-> Read and evaluate error code with SAFECONF.
State Meaning
There is no switching signal at the relevant input.
The switching signal is active at the input.
Diagnostics error (see user manual for error code)
Output is inactive
Output active
Diagnostics error (see user manual, e.g., no power supply
present, cross circuit or overload)
