  • Page 18 NOTES: USE WITH INDUCTIVE LOADS AND TRANSFORMERS Connect a varistor (MOV) between each wire of the primary transformer and ground. Varistor data: rated voltage 660Vrms,…, 1000Vrms; minimum energy 100J The maximum current controllable by the device is less than the product’s rated value (see technical data). In ZC and BF trigger mode, use the Delay-triggering function to limit peak magnetization current.
  • Page 19 variable cycle time (GTT) This mode controls power on the load via a series of conduction ON and non conduction OFF cycles. The ratio of the number of ON cycles to OFF cycles is proportional to the power value to be supplied to the load. The CT repeat period is kept to a minimum for each power value (whereas in ZC mode the period is always fixed and not optimized).
  • Page 20 Phase angle (PA) This mode controls power on the load via modulation of trigger angle q Example: if power to be transferred to the load is 100%, q = 180° or if power to be transferred to the load is 50%, q = 90° Figure 23 Resistive load Inductive load...
  • Page 21 RMS current limit The option for controlling the load current limit is available in all work modes. If the current value exceeds the limit (settable in the nominal full-scale range) in mode PA the conduction angle is limited, while in zero-crossing mode (ZC, BF, HSC) the cycle time conduction percentage is limited. This limitation ensures that the RMS value (i.e., not the instantaneous value) of the load current does NOT exceed the set RMS current limit.
  • Page 22 To conduct inductive loads controlled in PA mode, do not use delay triggering; instead, use the phase Soft-Start ramp. Figure 27 Example of phase ramp to fire Example of firing with Delay-Triggering a transformer in PA mode of a transformer in ZC mode Comparison of method to fire a transformer: Soft-Start Ramp (for PA mode) / Delay triggering (for ZC and BF mode) 80994B_MHW_GTF-Xtra_05-2016_ENG...
  • Page 23 vercurrent fault Protection This function eliminates the need for an external extra-rapid fuse to protect the device. The SHORT_CIRCUIT_ CURRENT alarm trips when the peak current on the load exceeds maximum permitted value (corresponding to twice the rating ) during the softstart ramp or at first power-on (with softstart ramp disabled). If configured (Fr.n parameter other than zero), the device restarts automatically in softstart for a maximum number Fr.n of attempts, beyond which it remains deactivated while waiting for manual reset with front panel key BUT or with the control via serial (bit 16).
  • Page 24 This digital input can be used to receive information on the % of power to be supplied to the load. The signal can be generated by a controller or external plc via digital outputs (logic output for Gefran instrumentation). This is obtained by alternating the output in ON for time TON with the output in OFF for time TOFF.
