Error codes
E01 Possible cause : Phase-fault in the three-phase network
Short-circuit or fault in the thyristor
Motor is not connected
Supply frequency with oscillation higher than 10%
Type of motor connection is wrong
E02 Possible cause : The time of the ramp acceleration is shorter than the actual acceleration time since the function of the current limitation is activated.
E03 Possible cause : Ambient temperature higher than 40 degree celcius and current too high
Starting time with current limitation higher than specified by switch
Too many of successive starts
Fan is locked or defective
E04 Possible cause : Set of P21, P25 and P26 too low relating to the used motor
Load on the motor shaft too high
Too many of successive starts
E05 Possible cause : Pump is dry operating
Load decoupled from the motor shaft
E06 Possible cause : Short-Circuit between phases
Motor shaft is locked
E07 Possible cause : Network phase sequence inverted at the input
E08 Possible cause : Terminal board X2.3 and X2.5 is open (not connected to +24Vdc)
problems we may encounter
Motor does not run
Point to be checked : Wiring not connected
Corrective action : Check all power and control connections. For instance, check the digital input of extern error that must be connected to +24V.
Point to be checked : Wrong programming
Corrective action : Check if the parameters are correct programmed for the application.
Point to be checked : Error
Corrective action : Check if the Soft-Starter is not disabled due to a detected error condition.
Motor speed too high or too low
Point to be checked : Motor nameplate data
Corrective action : Check if the motor is used according to its application.
Display OFF
Point to be checked : HMI connections
Corrective action : Check the HMI connections to the Soft-Starter (Control board CCS3.0X)
Point to be checked : Check the supply voltage X1.1 and A1.2
Corrective action : The rated values must meet the following requirements :
For 220-230 Vac Min : 187 Vac Max :253 Vac
For 110-120 Vac Min : 253 Vac Max : 132 Vac
