1. Brief summary
The PMF-LED-HI-SIL is a monitored warning light for use in safety-related applications in industrial, commercial
and small business environments.
The LED warning light offers various operating modes to create three different optical warning signals. The sig-
nal is checked by a monitoring circuit that does not affect its functionality. Errors are sent via a fault indicator
relay with positively driven contacts to a higher-level control unit, see Illustration 3 - simplified diagram.
The lens is formed like a Fresnel lens and achieves a good bundling of light on the horizontal plane through its
configuration of the LEDs. This allows for very good detection over great distances with only low power con-
sumption.
2. Intended use
The operational safety of the device and the connected system can only be guaranteed when used as intended
in accordance with the specifications of the operating manual. Application-specific hazards can result from inap-
propriate or unintended use of this device.
