Field Diagnostics
Should trouble occur, the Field Diagnostics feature
may be used to help diagnose the problem. Field
diagnostics provides more detailed and definitive
feedback than the alarms, i.e. possible root cause(s)
for the alarm. For example, there may be many causes
for an Actuator Fail alarm. Field diagnostics may be
displayed by MPA Config as shown here.
Field diagnostic may be displayed by the local display
by entering setup mode. In Setup Mode, the first entry
is Field Diagnostics having visible code “Fd”. Its value is
0 if there is no fault. If there is a fault, its code is from 1
to 28. If there are multiple faults, only the first of those
faults in the following list will be seen. When that fault
is corrected, the next fault will display if present.
In DCMLink the Field Diagnostics Code is indicated in
the Status Monitor.
Figure 29.
Fd Fault Codes
1. MCP23 Chip will not initialize (pertains to a three phase AC motor type)
2. Motor is wired to turn in the wrong direction
3. Self-detected wiring fault (Emergency Shut Down - LE)
4. Host transmitted ESD command (Emergency Shut Down - LE)
5. Lost Phase, pertains to a three phase AC motor type - PH
6. Motor has over-heated or overload relay trip (Motor overload - OL)
7. Stall Alarm. No motor movement after excess time of power applied - SA
8. Lost Control Voltage (Loss of power for motor control - LC)
9. Contactor is engaged, but there is no AUX feedback (= Control Failure)
10. SPI communication failure for GPA chip
11. AUX feed-back alarm (= Incorrect AUX feedback from contactor)
12. Three consecutive overshoots of the port
13. RDM is not communicating and is required (Communication Error - CE)
14. No input from Torque Encoder. Check for cable connection problems or encoder failure
15. Torque OCF bit is low. Power supply to the Torque Encoder is likely at fault
16. Encoder reports that Torque Encoder value is invalid
17. Torque Encoder Parity error
18. Torque Encoder Magnet is out of range
19. Over-Torque. Torque value is greater than the Torque Limit
20. Value from the Torque Encoder is out of range (invalid instead of over-torque)
21. No input from Position Encoder. Check for cable connection problems or encoder failure
