Each valve driver output is an RJ50 connection that contains two valve
drive output lines and a cable loss detection loop.
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.
