The fixed controllers that have 24V dc input circuits are also equipped with a
high-speed counter. For high-speed counter use, follow the procedure below:
1. Turn off power to the fixed controller.
ATTENTION
2. Remove the SLC 500 cover.
3. Locate and cut jumper wire J2. The jumper is either beneath or to the right of the
battery connector. Do not remove the jumper wire completely, but make certain
that the ends of the cut jumper wire are not touching each other.
The High-Speed Counter jumper is located either beneath the battery connector OR to
the right of the battery connector.
When power is applied to the controller, hazardous electrical
potentials exist under the front cover. See page 6 for further
