4. Monitoring and Diagnostic Facilities
4.1 Local Facilities
LCD Displays – The LCD displays an array of data concerning the status of actuator components in
clear, graphical or textual language. The MX is available with ten languages: English,
Spanish, German, French, Italian, Portuguese, Mandarin, Russian, Bahasa Indonesia
and Katakana.
Normal Display – The normal display illustrates current valve position and status.
Alarm Functions – Alarm functions (active alarms will be toggled every four seconds)
that may be displayed include:
Valve Jammed - Valve cannot start moving•
Lost Phase - One of three phases lost•
Motor Overtemp - Thermistor range exceeded •
Overtorque - Torque exceeded in mid-travel•
Hardware Failure - Indication•
DDC, Profibus, • F
o u n d a t i o n Fieldbus, DeviceNet off - Enabled, but “OFF”
ESD Active - ESD signal active•
Inhibit Active - Inhibit signal present•
No analog signal - 4–20 mA signal absent (Modutronic enabled, red selector switch in •
“REMOTE”)
DDC, Profibus, • F
o u n d a t i o n Fieldbus, DeviceNet comm loss - Enabled, signal absent
Analog Output Loss - Enabled, but output current loop open•
4.2 Diagnostics
Standard Diagnostic Screens – Diagnostic screens may be accessed quickly through the Setup
dialogue or the MX Dashboard Software solutions package. These screens provide detailed data of
actuator status. Included are:
Hardware• – status of electronic components such as thermistor, encoder, power board,
DDC/FF/PB/DeviceNet network board, analog board, DIGIN and ANIN (digital in and analog in)
Motor• – Phase rotation, winding temperature
Power Supply• – Maximum and minimum voltage, frequency
Identification• – Tag number, serial number, order number, software revision
Torque Profile• – Record of the REFERENCE and the LAST reading of the breakout, peak running
and ending torques, in both the open and close directions. Torque is displayed for reference only.
View DNET Status • – Checks for Standby, Recoverable Fault, Nonrecoverable Fault, and View
Network Status
Operation Log• – Actuator turns, contactor operations, motor run-time, stroke time, manual
operations
