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 Synergy is operating outside specified limits.
•
Check enclosure ventilation and airflow around the Synergy
•
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 your supplier
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 Synergy 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 Synergy has detected that the SCRs are not operating as expected.
•
Check all incoming and outgoing connections.
