Trip Codes (from Trip Log)
Number & Name Description
101
Input Side Phase
Loss
Phase L1 missing at the instant of start up�
• The L1 phase is either missing or at a very low level�
• Check all incoming connections�
• If a main contactor is being controlled by a digital output set to “Running,” check that
“Contactor Delay” (under “Start Settings”) is sufficient�
102
Input Side Phase
Loss
Phase L2 missing at the instant of start up�
• The L2 phase is either missing or at a very low level�
• Check all incoming connections�
• If a main contactor is being controlled by a digital output set to “Running,” check that
“Contactor Delay” (under “Start Settings”) is sufficient�
103
Input Side Phase
Loss
Phase L3 missing at the instant of start up�
• The L3 phase is either missing or at a very low level�
• Check all incoming connections�
• If a main contactor is being controlled by a digital output set to “Running,” check that
“Contactor Delay” (under “Start Settings”) is sufficient�
104 - 117
Input Side Phase
Loss
Any or all phases missing when the motor is being controlled (running)�
• L1, L2, or L3 are missing or at a very low level�
• Check all incoming connections�
• Check any fuses/breakers incorporated in the power circuit�
201
Maximum
Temperature
Exceeded
Internal heatsink temperature has exceeded 80°C�
• It is possible the SR55 is operating outside specified limits�
• Check enclosure ventilation and airflow around the SR55�
• If the unit trips immediately, the internal temperature sensor could be faulty�
208
Thermal Sensor Trip
Thermal sensor failure�
• The internal temperature sensor has failed�
• Contact AutomationDirect�
300-307
Thyristor Firing Trip
One or more of the internal control thyristors (SCRs) have failed to turn on properly (In-Line
“Firing Mode”)
• The SR55 has detected that the SCRs are not operating as expected�
• Check all incoming and outgoing connections�
350-357
Thyristor Firing Trip
One or more of the internal control thyristors (SCRs) have failed to turn on properly (Delta “Firing
Mode”)�
• The SR55 has detected that the SCRs are not operating as expected�
• Check all incoming and outgoing connections�
401
Motor Side Phase
Loss
One or all of the phases are missing on the motor side during the instant of start up
• T1, T2, or T3 are missing or at a very low level�
• Check that the motor is connected to T1, T2 and T3�
• Ensure any disconnecting device between the SR55 and the motor is closed at the instant of
start up�
402-403
Motor Side Phase
Loss
One or all of the phases are missing on the motor side during the instant of start up when the
motor is being controlled�
• T1, T2 or T3 are missing or at a very low level�
• Check all incoming and outgoing connections�
601
Control Voltage Too
Low
The internal control supply of the SR55 level has fallen to a low level�
• Can be caused by a weak 24VDC/115VAC/230VAC control supply�
• Ensure 24VDC/115VAC/230VAC supply meets the requirements specified in “Electrical
Installation” Chapter 2 or the Quick Start Guide�
701-710
Sensing Fault Trip
One or more of the internal control thyristors (SCRs) have failed to turn on properly�
• The SR55 has detected that the SCRs are not operating as expected�
• Check connections all incoming and outgoing connections�
801-802
Fan Problem
One or more of the internal cooling fans has failed�
• To ensure the heatsink is cooled sufficiently, the SR55 will trip if the fans fail to operate�
• Check SR55 fans for signs of damage or contamination�
1001
Short Circuit
Thyristor
One or more of the internal control thyristors (SCRs) have failed short circuit�
• The SR55 has detected that the SCRs are not operating as expected�
• Check all incoming and outgoing connections�
1101
Low Current Trip
The motor current has been lower than the “Low Trip Level” for the “Low Trip Time” (under
“Motor Protection”)�
• This trip is not active during soft start and soft stop and is “off” by default�
• If the Low Current Trip is not required, turn “off” in “Trip Settings�”
