NOTE

See Appendix E for additional information about Automation.
A Branson actuator requires 2 start switches and emergency stop connection. Stands on a base include this
connection (factory installed and connected from the base) while the stand on a hub and actuator (alone)
applications require the user make their own start switch/E-stop connections, as follows:
Figure 4.11 Start Switch Connection Codes
NOTE
i
Solid state devices may be used in lieu of mechanical start switches providing their leakage
current does not exceed 0.1mA.
NOTE
i
Start Switches PB1 and PB2 must be closed within 200 milliseconds of each other, and
remain closed until the WELD ON signal is active, to effect a start condition.
BASE/START is the DB-9 female connection on the back of the actuator. Your cable requires a male DB-9
(D-shell) connector.
