    Chapter 5 OPERATION THYRISTOR FIRING MODES General introduction TE300 controllers have the following thyristor firing modes: · Burst-firing with configurable cycle time · Advanced Single-cycle (firing by cycles and non-firing by half-cycles) · Logic (ON/OFF). As an option, DC component elimination for 3-wire configuration is available in Burst-firing and Logic modes.

  • Page 44: Burst-Firing' Mode

    ‘Burst-firing’ mode Burst-firing mode is a duty cycle mode which consists of supplying a series of complete mains voltage cycles to the load. Load voltage Figure 5-1 ‘Burst-firing’ mode (T F - firing time; T M - modulation time) Thyristor firing and non-firing are synchronised with the mains and, for a resistive load, are performed at zero voltage for each load.
  • Page 45 The modulation time in ‘Burst-firing’ mode is variable according to the power demand. For example, for ‘8-cycle Burst-firing’: · At 50% power, the typical value of the modulation time is 0.32s (at 50Hz): 8 firing and 8 non-firing cycles. · For a setpoint less than 50%, the firing time remains constant (8 cycles), the non-firing time increases and, as a consequence, the modulation time increases.

  • Page 46: Single-Cycle' Mode ('1-Cycle Burst-Firing')5-5

    ‘Single-cycle’ mode (‘1-cycle Burst-firing’) This Burst-firing mode has a single firing cycle or a single non-firing cycle and is called ‘Single- cycle’ (or ‘standard Single-cycle’) firing mode. Load voltage T NF 50% power T F = T NF T NF 25% power T NF = 3 T F T NF...

  • Page 47: Advanced Single-Cycle' Mode

    ‘Advanced Single-cycle’ mode In order to minimise power fluctuation during the modulation period, the ‘advanced Single- cycle’ thyristor firing mode uses: · A complete number of cycles for firing · A complete number of half-cycles for non-firing Load Standard Single-Cycle (1 cycle Burst-firing) voltage Load Advanced Single-cycle...

  • Page 48: Logic' Mode

    ‘Logic’ mode The ‘logic’ thyristor firing mode (ON/OFF) controls power in the load proportionally according to the firing time set by the logic control signal. This firing mode is activated by a signal greater than 50% of full scale. It is deactivated when the signal falls below 25% of full scale.

  • Page 49: Control Operation

    CONTROL OPERATION TE300 controllers include an internal control loop. The control algorithm of the TE300 series takes into account the value of the r.m.s. load voltage squared. The square of the r.m.s. load voltage represents the power dissipated in a purely resistive load whose resistance remains constant with temperature.

    COMMISSIONING PROCEDURE - SAFETY Important! Eurotherm cannot be held responsible for any damage to persons or property or any financial loss or costs arising from incorrect use of the product or failure to observe the instructions contained in this manual.

  • Page 52: Checking The Characteristics

    CHECKING THE CHARACTERISTICS Load current The maximum load current must be less than or equal to the value of the nominal current of the controller, taking into account the load and power supply variations. If three identical loads are configured in closed delta, the current of each phase of the controller is √3 times greater than the current in each branch of the load.

  • Page 53: Powering Up The Controller

    POWERING UP THE CONTROLLER TE300 series controllers are ready to operate correctly immediately after installation and wiring in accordance with this user manual. After checking that the nominal parameters of the controller (voltages, currents, input signal and load configuration) are compatible with those of the installation, apply volts to the controller.

  • Page 55: Chapter 7 Maintenance

    Chapter 7 MAINTENANCE DANGER! The controller must be maintained by personnel qualified and trained to work with low voltage electrical equipment in an industrial environment. The user’s installation must be protected upstream (non high-speed fuses, thermal or electromagnetic circuit breaker, suitable fuse-isolator) and must comply with current standards.

  • Page 56: Thyristor Protection

    For the use of high-speed fuses in short-wave infrared applications, please contact Eurotherm Controls. To protect the thyristors in the TE300 series, 3 fuses and a tri-polar fuse-holder must be used. Details of these are given in the following table.

  • Page 57: Servicing

    SERVICING TE300 controllers must be mounted with the heatsink positioned vertically, with no obstructions above or below which could inhibit or impede airflow. Attention! If several units are mounted in the same cabinet, they should be arranged in such a way that air expelled from one cannot be drawn into the unit located above it.
