Interlock
The BOOSTIK includes a safety Interlock function. The function immediately shuts
down emission when a circuit loop connected to pins A3 and A4 is either opened or
shorted to ground.
When the module is inserted into an ACOUSTIK shelf slot, its interlock circuit is
connected as part of a loop circuit with all installed modules and an external door
switch circuit to protect the operating enclosure. For more information regarding the
Interlock and how to connect a door safety switch, refer to the
Koheras ACOUSTIK
Product Guide .
Fiber tip cleaning
The output aperture of the BOOSTIK is a fiber with a optical connector. At the tip of
the connector is a fiber facet where Class 3b or Class 4 emission are present.
Without proper care the facet is easily contaminated or damaged affecting the
output.
To clean it, only use cleaning tools specifically designed for use with optical fibers.
Always use extreme caution when cleaning fibers.
Examples of appropriate cleaning tools are:
Lens cleaning tissue (lint free wipes) see Figure 11
Optical fiber cleaning tool see Figure 12
Note: Before connecting fibers and their connectors, always inspect their facets using
a suitable fiber microscope. Refer
Warning: Ensure the module is powered off before using a microscope to check its
output fiber facet.
