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 provi-
des for the timing and check of a safe contact (17-18) as well as the functional check
of the module at each re-start, according to the methods described in this document.
There are also some unsafe signalling contacts and some LEDs for displaying the
state of the device.
3.2 Device functions
This device is suitable for the following applications: as a safety timer module in
safety circuits up to category 3 and PL d acc. to EN ISO 13849-1 and SIL CL 2 acc.
to EN 62061.
- LED indicators to signal the state of the device (Out, Fault) and the presence of a
power supply (Power).
- 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 Operating states
State
POwER-
Device state in the time
ON
between applying the supply
voltage and conclusion of the
internal self-test.
ERROR
State of the device, if an
internal failure has been
detected in the device itself.
DELAY
State of the device during the
timing function.
RUN
State assumed by the device
after the DELAY state, if no
error has been detected.
Legend:

4.3 Description of operation
when the timer module is receiving a power supply, the Power LED lights up, and the
device enters the POwER-ON STATE, detects the time set in the selector (only for
versions with selectable time) and conducts an internal self-test.
If the test is not passed, the module enters the ERROR STATE.
In ERROR state, the timer module immediately places itself in safety mode by
deactivating all the relays and activating the Fault LED and the relative signalling
output Y14.
If the test is passed, the module enters the DELAY state and performs the timing
function and then enters the RUN state by activating the relays and the Out LED. If the
timing phase is not successful, or if a safety relay (K1, K2) does not switch, the system
immediately enters the ERROR state.
