Settings and Adjustments
The relay module has three site-configurable jumper options.
If necessary, clip the site-configurable jumpers with side cutters and remove the
resistors from the relay module.
Note: Clipping and removing a site-configurable jumper enhances the level of
safety.
Clipping and removing a jumper after 200 hours of operation causes a
non-resettable fault 100. The relay module must then be replaced.
