Limitorque QX Electronic Actuator FCD LMENIM3306-06 – 07/14
82
---% OPEN, TORQUE TIMEOUT – The torque switch timed out after the actuator determined that it has reached its torque seat
“SET LIMITS” – Normal display if red selector knob is in “LOCAL” or “REMOTE” and position limits have not been set
“INITIALIZE” – “INITIALIZE” will be displayed if module has no actuator configuration. No operation will be permitted
until initialization has been completed. Refer to “ROM ERROR” for routine on next page. See Figure 5.1.
“---% OPEN, THERMISTOR” – There is a failure with the motor thermistor
“---% OPEN, KNOBS” – There is a failure with the local knobs
“---% OPEN, DDC NOT PRESENT” – DDC board expected but not found (missing or not communicating)
“---% OPEN, FF NOT PRESENT” – FF board expected but not found
“---% OPEN, PBDP NOT PRESENT” – Profibus DP board expected but not found
“---% OPEN, PBPA NOT PRESENT” – Profibus PA board expected but not found
“---% OPEN, DN NOT PRESENT” – Device Net board expected but not found
“---% OPEN, ANG1 NOT PRESENT” – Analog 1 board expected but not found
“---% OPEN, ANG2 NOT PRESENT” – Analog 2 board expected but not found
“---% OPEN, CONTACTOR” – Contactor failure
“---% OPEN, ENCODER” – Encoder failure
“---% OPEN, R1R4RM RLY FAILED” – R1-R4 board relay check failed
“---% OPEN, R5R8 RLY FAILED” – R5-R8 board relay check failed
“---% OPEN, DDC FAILED” – Communication with the main board failed, or hardware fault
“---% OPEN, FF FAILED” – Communication with the main board failed, or hardware fault
“---% OPEN, PBDP FAILED” – Communication with the main board failed, or hardware fault
“---% OPEN, PBPA FAILED” – Communication with the main board failed, or hardware fault
“---% OPEN, DN FAILED” – Communication with the main board failed, or hardware fault
“---% OPEN, R1R4RM NOT AVAIL” – R1-R4 board expected but not found
“---% OPEN, R5R8 NOT PRESENT” – R5-R8 board expected but not found
“---% OPEN, ENCODER WARNING” – The encoder has not yet failed, but there was a momentary glitch detected.
If the glitch persists, encoder failure will be reported.
“---%, OIL OVER TEMP” - Arctic unit oil temperature too high
“---%, HIGH LINE VOLTAGE” - QX Line voltage too high to run safely
“---%, MC COMM LOSS” - QX Communication loss with motor controller board
“---%, MC BOARD FAULT” - QX Motor Controller Board fault
“---%, MOTOR FAULT” - QX Motor Fault
“---%, LOW LINE VOLTAGE” - QX Line Voltage too low to run safely
RAM Error
The QX processor continually checks RAM for memory corruption errors. If corruption is detected, the processor will
force a reset to clear RAM. The LCD will temporarily display the following prior to this reset:
