Configure the Model 494.79 Multiple Universal Driver (MUD) Board
1. In the Hwi File Editor window, expand the hardware tree to display the
494.79 Multiple Universal Valve Driver [19] settings.
2. In the Interlock Enable list, click False.
Note
Standard MTS servo valve cables do not support the cable-loss interlock
detection circuit so the Interlock Enable setting must be set to False.
3. In the Range box, enter the servovalve drive current value that matches the
coil rating of the servo valve. Selections include: 25 mA, 50 mA, and 75
mA.
MTS servo valves have a coil rating of 50 mA.
Note
Some custom systems require a user-defined drive current value. For
these systems, the range setting is set to zero and a resistor is installed
on the MUD board.
4. Repeat this procedure for each of the “494.79 Multiple Universal Valve
Driver” outputs in the controller.
