Output connections Each valve driver output is an RJ50 connection that contains two valve drive
output lines and a cable loss detection loop.
Cable loss detection The cable loss detection wire loops out to the servovalve and back to the driver
output allowing MUD board logic to detect a cable break or a cable disconnect at
the MUD board output. A cable loss will not be detected if the cable is
disconnected at the servovalve.
Note Different customer actuator sign conventions might require alterations to
the cable polarity. Contact MTS for more information.
Improper operation can damage valve driver cards.
Damage can occur if you connect a high-level signal to a valve driver card
when the chassis power is off.
Do not apply a high-level signal to a valve driver card when the chassis power is
off. Disconnect power from any externally powered devices before you switch the
chassis power off.
