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.
4.5.9 Serial (RS-232) Port Connector
An RS-232c serial port (DB-9 format) is provided for the Host Computer option. Only
three data leads of this port are supported at this time (Data Send TXD, Data Receive
RXD, and Signal Ground GND). The remainder of the leads are ‘reserved’. A null modem
cable is required.
The comport parameters are fixed, can not be altered or viewed in the menu.
The fixed values are:
1. com speed = 9600 baud
2. no parity
3. 1 stop bit
4. 8 data bits
NOTICE
Solid state devices may be used in lieu of mechanical start switches
providing their leakage current does not exceed 0.1mA.
NOTICE
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.
NOTICE
Refer to the Branson Automation Guide (EDP 100-214-273) for
additional information about selection and use of Input and Output
features.
