Q. Should I ground the RETURN lines in the USER I/O cable?
A. If required: this generally is not a problem. If problems occur, see “OTHER THAN 24
VOLTS”.
Q. What are those SQUARE PLASTIC HOUSINGS on the cables?
A. They are ferrites that are used to reduce crosstalk and interference from entering the
system. DO NOT remove them.
Q. How LONG can I run the CABLES?
A. Cable sets are available in 8, 15, 25, and on special order 50-foot lengths. Contact
Branson Product Support or Customer Service if you have special needs.
Q. Can I run the Branson welder cables in a WIRING TROUGH with other system
cables?
A. Generally yes. But it would be best to avoid other noise trouble source cables or wiring.
Q. What other system cables might cause a NOISE TROUBLE SOURCE?
A. Avoid wiring of devices such as solenoids, large relays, motors, or anything that has the
potential of large inductive currents. Digital devices may also create broad-spectrum
noise. Generally, all automation controls can be noise generators.
Q. Why do you require the READY signal to be monitored by the system PLC?
A. The welder mandatory requirements dictate the unit be READY or else the unit will
DISREGARD any start command.
Q. Why must I MAINTAIN THE START SIGNAL?
A. This is the way the built-in safety circuits operate. Also, the vast library of error-
detection firmware code is based on these same requirements. Watch for the PB RELEASE
signal, then you can release the START SIGNAL
Q. What can I do to make sure I run at MAXIMUM CYCLE RATE for my machine?
A. You can:
• RESET immediately after an GENERAL ALARM output
• RELEASE the DUAL START inputs immediately after an GENERAL ALARM output
• RELEASE the DUAL START inputs immediately after sensing PB RELEASE output
• Never run in an open-loop mode, if possible. Fixed timing can be too short should a fault occur, or
may be longer in time than is necessary
Q. Do all models run at the same CYCLE RATE?
A. See above.
Q. Are there any special requirements for operation with the ACTUATOR UP-SIDE
DOWN?
A. Always let Branson know when you plan to run in this manner. Model-specific advice will
be provided.
Q. Are there any special requirements for operation with the ACTUATOR
HORIZONTAL?
A. Always let Branson know when you plan to run in this manner. Model-specific advice will
be provided.
