    Temvar GDE2 LED Displays STAND-BY ⊗ ⊗ ⊗ ⊗ LED lights up when all internal electronic voltages are okay. As soon as the closed-loop controller is enabled, the system voltage is also checked. Main power with clockwise rotating field, phase failure and tacho monitoring.

  • Page 19: Functional Description Of The Inputs And Outputs

    Temvar GDE2 FUNCTIONAL DESCRIPTION OF THE INPUTS AND OUTPUTS Analog Inputs The analog inputs may only be connected using shielded leads. The shield should only be connected to the grounding system at one point, across a broad contact surface in close proximity to the device.

  • Page 20: Analog Outputs

    Temvar GDE2 Auxiliary input - current controller A voltage of + 10 V at terminal X2: 5 means nominal device current. Caution! This auxiliary setpoint value is added to the main setpoint value from the speed controller. The current limit must be set low enough to ensure that the sum of the two setpoint values does not exceed + 10V.

  • Page 21: Control Inputs And Signal Outputs

    Temvar GDE2 Control Inputs and Signal Outputs Inputs and outputs are separated from the electronics potential by optocouplers. They have their own 24 V system power supply, designated with +L and -L. The reference potential -L, terminal X1: 14, is to be connected to the reference potential of the system controls.
  • Page 22 Temvar GDE2 Signal output "stand-by" Terminal X1: 12 is supplied with voltage +L if the electronics power supply is present. As soon as the closed-loop controller is enabled, the main power is also checked at terminals X3: 1 + 2 + 3. For devices with fans, this stand-by signal also incorporates a temperature switch.

  • Page 23: Functional Description

    Temvar GDE2 FUNCTIONAL DESCRIPTION Setpoint Value Integrator With a positive setpoint step-change at terminal X1: 1, the comparator (1) inverts into the negative. The capacitor C is charged via resistor R+. The rate of charge depends on the position of the potentiometer +B. When the output voltage on integrator (2) reaches the level of the setpoint value at X1: 1, the comparator (1) returns to 0 and the capacitor C is no longer charged.

  • Page 24: Speed Controller

    Temvar GDE2 Speed Controller The speed controller is a standard PI-controller. Proportional gain is determined by R9 and potentiometer V and the integral-action time by C2. Right-hand stop of the potentiometer V is equal to the largest gain. The closed-loop controller output can be measured at test point "X...

  • Page 25: Current Controller

    Temvar GDE2 Current Controller he current controller is a standard PI-controller. Proportional gain is determined by R8, the integral-action time by C1. When using auxiliary input X2: 5, it must be taken into consideration that the two setpoint values add up. Together they must not exceed + 10 V. The current controller output can be measured at test point -XI.

  • Page 26: Thyristor Outputs

    Temvar GDE2 Thyristor Outputs The selected current direction +I activates the corresponding pulse transformers and clears the AND-gates for the firing pulses. The thyristors require a holding current of approx. 100 mA. If this current is not achieved during the firing phase, the thyristor blocks again after the firing pulse has been removed.

  • Page 28: Installation

    Temvar GDE2 INSTALLATION Dangers When this device is operated, certain parts of it are automatically under dangerous voltages, which can lead to serious bodily injury or death. The following precautionary measures must be followed to minimize the risk of injury or death.

  • Page 29: Recommended Procedure

    Temvar GDE2 Recommended Procedure Dangers Up until installation point 4 the device must remain isolated from the power supply drive will start once the closed-loop controller is enabled! Check that all main power ground wires and electronic terminals are connected correctly.

  • Page 30: Optimisation

    Temvar GDE2 OPTIMISATION For most applications, the standard assignment for the current and speed controllers is fully sufficient. It is advisable, however, to check the transient response of the motor in the event of abrupt changes in the setpoint value and to optimize this using potentiometer V .

  • Page 31: Fault Occurrence

    Temvar GDE2 Connect the field supply. Set the RC decade to standard assignment -potentiometer to center point. Switch on the drive, enable the closed-loop controller. Set approx. 30% of the maximum speed and enter the setpoint value change using switch SW. Optimize speed controller first with R9, then with C2 so that the oscillogram appears similar to the one shown in the diagram.
