APPENDIX C
PARALLEL WIRING GATE OPERATORS
In the absence of Master/Slave firmware, two SL 1000-X1s may be parallel-wired as shown below.
NOTES:
1. When parallel wiring the RADIO INPUT terminals, do not connect the POWER output
from one board to the POWER output on the other board. This will damage the
controller boards.
2. Do not parallel wire the MAGLOCK terminals. Auxiliary device circuits may be
damaged if separate auxiliary devices are used with each board.
3. Both gate operators must have the same settings for:
a. Gate Control Settings (see programming table in Part 2, para. J, Basic Gate
Operator Programming).
b. Current Sensitivity pots (Left & Right Reverse, Inrush)
c. Limit Cams
CAUTION
The Signal and Common terminals on one board MUST connect to the corresponding
Signal and Common terminals on the other board.
DO NOT INTERCHANGE SIGNAL AND COMMON TERMINALS.
