Installing the Receiving Unit
AUTEC - Dynamic Plus series
8.3 Wiring
Wiring inside the Receiving Unit shall be made with electrical wires resistant
to at least 125°C usage temperature.
Group all cabling wires so that they are far from the radio area in the electronic
board, in order to avoid interference and danger related to electrical safety.
The current of STOP outputs is interrupted at regular intervals for approx. 1
ms every 100 ms. Risk assessment must consider this interruption. If STOP
outputs are used to power electronic devices, check that they are compatible
with this recurring interruption (use suitable lters if necessary).
When failure is detected on the SAFETY outputs, the STOP outputs are
automatically opened within 200 ms. Risk assessment must consider this
delay.
SAF_1 and SAF_2 outputs are designed to drive power loads and are
protected by means of fuses and transils, to ensure the longest lifetime in
most applications.If these outputs are connected to inductive loads (i.e.
solenoid valves, relays), it is recommended to connect a reverse recovery
diode close to the load, to further reduce the eects of demagnetisation
currents.
8.4 At end of installation
Correctly close the Receiving Unit in order to maintain the protection from
dust, contaminants and water:
- make sure that the gasket is intact and correctly seated,
- check that the housing parts correctly t so that they overlap,
- tighten the screws.
