GE DS200TBQBG1A Gas turbine counter plate

Use the following procedures when the system is not working correctly after calibration. 6.3.1 Green LED off Power supply voltage out of range Verify voltage level. (Refer to Chapter 2 Product Information on page 3). Switch-off / switch-on sequence too fast Switch off the system for at least one minute before re-applying AC power. Drive protection is activated Look for a short circuit between the power connector terminals. Voltage from a motor cable or choke terminal, short circuit to ground Remove the motor cables from pins 17 and 18 of the power connector, switch on the drive and if the green LED is now lit, check the cables.

Braking resistor overheating or BR LED is lit 

Fault in the braking resistor circuit This symptom may occur when the signal connector is not inserted. Check the power supply voltage is not excessive. Heavy working cycle Increase the acceleration and deceleration time, or fit an external braking resistor. Braking resistor is short circuit Ensure the braking resistor connections are correct. (Refer to Chapter 4 Electrical Installation on page 14). Value for the resistor too low Ensure the correct value for the resistor is being used. (Refer to Chapter 4 Electrical Installation on page 14).

Motor not in full control

 Tachogenerator cables reversed Reverse the tachogenerator cables. Motor cables reversed Reverse the motor cables. No tachogenerator signal on pins 11 and 12 Check the tachogenerator and the tachogenerator cables. RT resistor not fitted on daughter board Calculate the correct value for the RT resistor see section 5.1 Setting up the drive on page 35 to adjust the components. Speed reference signal on input pins 9 and 10 Reduce the speed reference signal to less than 1mV.
