6.4.4 Calibration
This procedure it's necessary to give set point to Heater Break. CD3000M reads the load current
many times and when the value is the same for three times takes it as set point.
Calibration procedure:
• verify that connections are correct;
• supply the thyristor unit;
• push "CAL" button on front of CD3200 unit,
or supply with 24Vdc terminals 1-2 or send command via RS485;
• the thyristor unit goes in conduction state to measure load current;
• all LEDS are ON, this means that calibration procedure is active;
• after one minute LEDS for H.B. and S/C switch off (calibration procedure is done);
• the thyristor unit is ready to work.
