• If the frequency is too high, SC557 (Applied Zero Cross Waveform Over) occurs.
• After power is switched on, if there are no zero-cross interrupt signals for more than 3 seconds with
the power relay on (other than when the upper unit is open), then SC547 occurs.
If the upper unit or exit unit is open at power on, the test is not done until after the upper unit or exit unit is
closed.
Switching on the Fusing Lamp Power
When the fusing lamp is switched on, the applied voltage is added in steps. This “soft start” prevents
problems that can be caused by voltages that fluctuate rapidly.
Fusing Temperature Control: Warm-up Sequence
Here is an example of the sequence of events for cold start, with the temperature below 15
