6.1. Starter software

The software version currently on the market is V1.1IE07.

Known bugs to date

Inversion of the state of the logic outputs (LO) in relation to those of the ATS46This problem will be corrected in the next version of the software.

Accidental tripping (PhF fault) as soon as the Run command is sent: On control boards with datecodes before 25-2002, a component fault which may cause PhF faults to be triggered accidentallyas soon as the Run command is sent. The component concerned has been replaced in boardswith date codes starting at 25-2002.Remedies:-Set the FrC parameter to 50or 60-Use a V1.1IE07 control board

Connecting the ATS in the motor delta winding

The ATS 48 Q range does not trigger a PhF fault if the branch corresponding to the one withoutisolated earth in the ATS is disconnected. For the 2 other branches, the ATS does detect the

break and triggers a PhF fault.

PhF fault in steady state without bypass on lines subject to significant interference

Notes:-A number of different faults may occur if ribbon cable J5, which connects the control board to thepower board, is connected incorrectly. Do not forget to lock the ribbon cable using the clamp onceyou have inserted it into the connector.

-Precautions to be taken in order to reverse the direction of rotation of the motor with the ATS48connected to the delta terminal. It is absolutely essential that the motor is wired as specified in theuser's manual. To reverse the direction of rotation of the motor, switch over 2 line phases and not2 motor phases.

6.2. Remote terminal software

The software for the remote terminal (ref. VW3G48101) is the same as that for the ATV28. Theonly difference between the 2 terminals is the keypad: the keypad for the ATS48 has 4 keys(Escape, Enter, Up, Down). The menus for the remote terminal are identical to those for the

ATS48 with the addition of a switch to lock access to the menus.

Note: The anode-cathode voltage drop is approximately 1 V when the thyristor is closed.

Test sequence:1. Switch open => The thyristor circuit is open (lamp off, mA=0)2. Close switch => The thyristor closes (lamp lights up, mA value no longer equal to 0)3. Open switch => The thyristor remains closed (lamp on, mA value no longer equal to 0)4. Reduce the voltage U to extinguish the thyristor

If operation differs from that described above, the thyristor has probably failed (short-circuit or opencircuit or leakage current)

OCF fault: Overcurrent fault

Principle:

This fault is detected during current measurements and by checking synchronization.

Conditions, fault trip thresholds:- Motor running: motor current > 10*ICL for 200 ms on one phase- Motor stopped: motor current > 0.06*ICL for 200 ms on one phase- Loss of synchronization after 500 ms following a bypass contactor open requestThis fault is stored in the EEPROM fault log.

Probable causes:

Impeding short-circuit on starter output

Internal short-circuit on the ATS (thyristor short-circuit, etc.)

The bypass contactor will not open (or the contacts are stuck) or opens subject to a delay inrelation to relay R2

ATS undersized in relation to the motor

Procedure, remedy:Power the ATS down in order to:

Check the power and motor cable insulation

Check the state of the thyristors (short-circuit)

Check the state of the bypass contactor

PIF fault: Phase inversion fault

Principle:

Reminder of IEC standards: These motor standards indicate that the motor shaft rotates in a clockwisedirection when motor terminals U, V and W are connected to line terminals L1, L2 and L3 respectively.

The ATS checks the phase rotation direction when the run command is sent. The user may configurethe phase rotation direction (forward or reverse) using parameter Phr. A PIF fault will occur if the linephase sequence is opposite to that configured in the ATS (Phr parameter).This fault is stored in the EEPROM fault log.

Probable cause:The line phase rotation direction and the wiring on the ATS result in a line direction which is oppositeto that configured with the PHR parameter.

Procedure, remedy:In the event of a PIF fault:1-Invert the configuration of the PHR parameter2-Shut down and then restart the ATS in order to acknowledge the PIF fault3-Send a short run command in order to check the direction of rotation of the motor

There are two possible scenarios:-The direction of rotation is correct => procedure complete

-The direction of rotation is incorrect => Switch over the 2 line phases (L1-L2 or L1-L3 or L2-L3) andinvert the configuration of the PHR parameter

EEF fault: Internal memory fault

Principle:The EEPROM memory generates a report following a read/write request.This fault appears if there is a problem (read or write) accessing the power or control EEPROMs.

Probable causes:

Power board EEPROM failed

Control board EEPROM failed

Procedure, remedy:

Disconnect then reconnect the control supply: if the fault does not disappear, replace thecontrol unit or power board.

CCF fault: Invalid configuration on power-up

Principle:On power-up, the ATS checks its configuration. If it detects an anomaly, it triggers a CFF fault. TheCFF fault can be reset as soon as it disappears.This fault is stored in the EEPROM fault log.

Probable causes:

Change in the ATS rating (the control board has been removed then reinstalled with a differentrating)

The electrical environment is subject to interference which has caused the configuration to beread incorrectly

Procedure, remedy:

Force a factory setting (drive drc menu)

Shut down then restart the product (if the fault is due to electromagnetic interference duringthe EEPROM read, it may disappear).

CFI fault: Invalid configuration

Principle:If a configuration that has been downloaded (via the RJ45 socket) is inconsistent (invalid parametervalue, the functions configured are incompatible, etc.), the ATS will trigger a CFI fault.This fault will be reset automatically once a consistent configuration has been downloaded.This fault is not stored in the EEPROM.

Probable causes:

An inconsistent configuration has been downloaded (parameters outside limits for example)

Procedure, remedy:

Download a consistent configuration

PHF fault: - Loss of line or motor phase(s)

Principle:

Causes of the PhF fault:-Indeterminate line phase rotation direction. This fault appears when the RUN command is sent.-Loss of the 3 line phases when the motor is running-The current is below the detection threshold (the PhL parameter can be set between 5 and 10% ofthe ICL) for 500 ms on 1 phase when the motor is running-The current is below the detection threshold (the PhL parameter can be set between 5 and 10 % ofthe ICL) for 200 ms on 3 phases when the motor is running-Loss of synchronization (line imbalance, toroid component, harmonics, electromagnetic interference)-One (or more) thyristor(s) is not firingThis fault is stored in the EEPROM.

No PhF fault check is carried out in the following 2 scenarios:-ATS connected in the motor delta winding-During 'motor preheating'

Procedure, remedy: Modify (increase) the PhL parameter setting If the line is imbalanced, check the distribution of the loads on the 3 phases Check that the thyristors are operating (firing) correctly

Experience to date: Loss of the 3 line phases when the motor is running Loss of the 3 motor phases when the motor is running or starting up Loss of a single power phase Motor rating undersized in relation to the rating of the ATS Wiring error with the ATS connected in the motor delta winding.

FRF fault: Line frequency out of tolerance

Principle:

The line frequency (abbreviated to Fr in this document) is checked when the control unit is powered upby measuring the line period. If Fr is within the permissible tolerances, it will not be checked againunless the control unit is powered down.

The fault thresholds are determined by the value of the FRC parameter:-FRC =50: fault indicating that Fr is outside the range [40-60Hz] (tolerance at 50 Hz: +/- 20%)-FRC =60: fault indicating that Fr is outside the range [48-72Hz] (tolerance at 60 Hz: +/- 20%)-FRC =AUT: fault for [Fr< 47.5 Hz] or [52.5 Hz< Fr< 57 Hz] or [Fr> 63 Hz]

This fault is stored in the EEPROM fault log.

Probable causes:

Line supply outside the tolerances permitted by the ATS

Use of a generating set with a frequency that varies outside the limits permitted by the ATSand/or ATS configured for automatic detection (FRC parameter = AUT)

The start command for the motor is being sent as soon as the control unit is powered up

Procedure, remedy:

Configure FRC=50 or FRC=60 as the tolerance is too broad for these configurations

The overload event is controlled in continuous operation (whether the ATS is bypassed or not)The 'overload' event is processed depending on the configuration of the OIL parameter:- OIL = Off: event ignored- OIL = ALA: switch to alarm mode- OIL = DEF: switch to alarm mode and to OLC fault

The overload time can be adjusted using the TOL parameter (increment = 0.1 second)The current threshold can be set using the LOC parameter. Threshold =(LOC*In)/100 where LOC is a% of In


Probable causes:-Nominal motor current setting too low (In parameter)-Motor overloaded in continuous operation-ATS rating too low

Procedure, remedy:-Set In > nominal motor current (nominal current on motor rating plate)-Use an ATS with a higher rating

OLF fault: Motor thermal fault

Principle:

The thermal state of the motor is estimated:-By calculating: (Imot/In mot) *(Imot/In mot)-For a reference temperature (ambient temperature) of 40C-For the temperature rise of the frame (iron) and the temperature rise of the winding (copper)

The OLF fault can be disabled.The thermal state is not calculated during braking or heating (the current measurement isinsignificant).Resetting the thermal state to zero forces thr=0 and can only be applied with the motor in freewheelmode.

Thresholds for changing to thermal fault mode: Cu thermal state > 200% or Fe thermal state > 125%Threshold for changing to alarm mode: iron thermal state > 110%

Only the iron thermal state appears on the display (thr parameter)In the event of a power failure, the downtime is measured by the ATS and used to estimate the motorthermal state when the power is restored.This fault can only be reset if the copper thermal state < 170% and the iron thermal state < 110%.This fault is stored in the EEPROM fault log.

Probable causes:

Motor overloaded

Starting cycles too severe (number of starts, duration, etc.)

Selected protection class too severe

Procedure, remedy:Change the thermal protection class by increasing the value of the tHp parameter.

OLF fault: Insulation fault (on product Y only)

Principle:

On range Y ATS products (fitted with a current transformer for each phase), the total of the 3 motorphase currents is measured in continuous operation.Fault trip threshold: I motor > 1.25 * I nominal motor for 2 secondsThis fault is stored in the EEPROM fault log.

Note: The fault code associated with the insulation fault is identical to the motor thermal faultcode (OLF).

Probable causes:

Motor not insulated correctly

Motor cables not insulated correctly

ATS insulation fault (filter board on sizes A/B/C/D)

Procedure, remedy:

Check the insulation of the cables, the motor and the ATS (filter board on sizes A/B/C/D)

OhF fault: Starter thermal fault

Principle:

(*) Affects ATS products fitted with fans

The ATS is protected by:- Estimating (calculating) the temperature rise of the heatsink and the silicon (thyristor)- Using a probe (probes) to measure the temperature of the heatsink: one PTC probe per product

for sizes A to D; one NTC probe per plug-in base for sizes E and F. The probes are attached tothe heatsink(s).

The time constants are calibrated for an ambient temperature of 40C.

A distinction is made between a warm state and a cold state in order to determine the trip time.The thermal state calculation is not active during heating.

Trip/acknowledgement thresholds for the OhF fault:-Trip when heatsink thermal state > 95C for sizes A, B, C, D-Trip when heatsink thermal state > 105C for sizes E, F-Acknowledgement possible when heatsink thermal state > 75C for sizes A, B, C, D, E, F

Fan control thresholds:- Start for a heatsink temperature > 50C- Stop for a heatsink temperature < 40C

Probable causes of OhF trip:

-Excessive starting time-Starting cycles too severe (e.g. intervals between consecutive starts too short, etc.)-Ambient temperature above 40C and ATS not derated-The drive or drives remain at stop (connectors, fan failed, supply voltage failed)-Insufficient ventilation-End of starting relay not used for ATS bypass

Procedure, remedy:-Check the supply voltage to the fans (12 V DC)-Check the fan connections-Ventilate the ATS-Bypass the ATS-Derate the ATS

-Choose an ATS with a higher rating

OtF fault: Motor thermal fault via PTC probe

Principle:

An external PTC probe can be connected to control the motor temperature. The PTC analogue signalis shaped by hardware (analogue signal) then converted in a logic signal which is received by the P.The way in which 'PTC probe thermal overshoot' data is processed depends on the value of the CTPparameter:

-CPT = Off: information ignored

-CPT = ALA: switch to alarm mode-CPT = DEF: switch to alarm mode and to OTF fault

Probable causes: Ambient temperature too high (above 40C) PTC probe short-circuit or open circuit PTC characteristics incorrect (ohmic value, operating curve) Motor not ventilated correctly Motor overloaded

Procedure, solution:

Wire a ~ 1500 ohms potentiometer between PTC1 PTC2 control terminals. Then check trippingin OtF control fault when potentiometer resistance is changed.

Check the value of the PTC resistance (R = 750 ohms at 25 C) at terminals.

ULF fault: Underload in continuous operation

Principle:

The ATS monitors the motor load in continuous operation (bypassed or not)ULL = Off adjustment parameters not visible on the HMIULL Off adjustment parameters visible on the HMI

The underload threshold (% of Cn) and the detection time (seconds) can be adjusted.Hysteresis: +10% in relation to the trip threshold

The 'underload' event is processed depending on the configuration of the ULL parameter:- ULL = Off : the event is ignored- ULL = ALA: switch to alarm mode- ULL = DEF: switch to alarm mode and to ULF fault

The ULF fault is stored in the fault log.

Experience to date: Motor underloaded (below the ULL parameter threshold) in continuous operation
