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.
