Start Switch Connection (Automation) - Branson 2000 Series Installation Manual

Start Switch Connection (Automation)

Start Switch Connection (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:

Solid state devices may be used in lieu of mechanical start switches providing their leakage
current does not exceed 0.1 mA.

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
welding 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 preclude re-occurrence of error message. Refer to Note above.
EMER STOP is an emergency stop switch, normally closed.
