Instruction Manual Installation Steps
4.5.8 Start Switch Connection (Automation)
A Branson actuator requires two 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 4.12 Start Switch Connection Codes
NOTE

Solid state devices may be used in lieu of mechanical start switches providing
their leakage current does not exceed 0.1 mA.
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.
PB1 and PB2 are two normally open start-switches which must be operated simultaneously to start the weld-
ing cycle. These must be closed within 200 milliseconds of each other, or error message "Start Sw Time"
will display. This doesn’t require a reset, but for the next cycle, switches must be within time limit to pre-
clude re-occurrence of error message. Refer to Note above.
EMER STOP is an emergency stop switch, normally closed.
