Configuration / operation

9.1

Procedure for configuration

General information:
• It is only possible to change the configuration (DIP switch, NC/NO evaluation, potentiometer,
input and output expansion) in configuration mode. Modifications during operation are not
accepted.
• A configuration change (DIP switch, NC/NO evaluation, potentiometer) is indicated in safety
mode by the "DEVICE" LED flashing green/yellow, but does not change the device function.
• In safety mode, if a change in the system configuration (input and output expansion) is
detected, the device switches to error mode ("DEVICE" LED and "SF" LED red). A restart is only
possible using Power OFF/ON.
Procedure for configuring a basic unit
1. Set the configuration (DIP, PAR, potentiometer, input expansion, output expansion) in
accordance with the desired function.
2. Connect the power supply.
3. If the device detects a modified configuration, it remains in configuration mode (LEDs flash)
during power up.
4. Confirm the new configuration by operating the SET/RESET pushbutton for more than 1s.
5. The configuration has been accepted and the device changes to safety mode.
Note
Configuration and setting the delay time
A change to the configuration must only ever be carried out when the system is disconnected
from the power.
In safety mode, an adjustment to the potentiometer does not result in a change to the
parameterized delay time.
A change to the potentiometer setting made during operation is not accepted and is indicated
in safety mode by a yellow/green flashing "DEVICE" LED. The device can be restarted by
performing a RESET (pressing the SET/RESET button) or by disconnecting and reconnecting the
supply voltage. Following a restart, the device remains in safety configuration mode during
power up (all safety-related outputs are shut down) until the new delay time is accepted by
pressing the SET/RESET button.
