3 DESCRIPTION
3.1 Device description
The safety device described in this manual is defined according to the Machinery
Directive 2006/42/EC as logic component for safety functions.
The safety modules to which these usage instructions refer are devices specifically
designed and manufactured for use on industrial machines. The safety function en-
sures that after the supply voltage is applied, the outputs are activated with a delay
(switch-on delay). The safety function is only performed after an internal integrity test
of the safety circuit and relay has been completed and if the feedback channel at Y1-
Y2 is closed. If there is no supply voltage, the module deactivates the safety outputs
within the specified release time.
3.2 Device functions
This device is suitable for the following applications: as safety timer module in
safety circuits up to category 4 and PL e acc. to EN ISO 13849-1 and SIL 3 acc. to
EN 62061.
- Timing circuits by means of safety system with self-monitoring and redundancy.
- Release command for interlocked safety devices.
- Indicator LEDs for the switching state of channels 1 and 2 (CH1, CH2) and applica-
tion of the supply voltage (PWR).
- In the event of a failure, the device switches to a safe state and deactivates the
safety output.
- Without muting input, no bridging of the safety function.
- Screw terminals or plug-in terminals with screw connections or spring terminals (de-
pending on the model).
- Snap-mounting on DIN rails.
3.3 Intended use of the device
- The device described in these operating instructions is designed to be applied on
industrial machines.
- The direct sale of this device to the public is prohibited. Installation and use must be
carried out by qualified personnel only.
- The use of the device for purposes other than those specified in these operating
instructions is prohibited.
- Any use other than as expressly specified in these operating instructions shall be
considered unintended by the manufacturer.
- Also considered unintended use:
a) using the device after having made structural, technical, or electrical modifications
to it;
b) using the product in a field of application other than as described in paragraph
TECHNICAL DATA.

4.2 Application example
The diagram illustrates the working principle of a typical circuit for monitoring a safety
device with guard locking in the de-energised state and manual release of the indi-
vidual doors.
