CAUTION
If the power supply voltage drops below the above range during operation, the alarm circuit will work and return
the SRCP controller to the initial state the same as just after power-on, or stop operation. To avoid this problem,
use a regulated power supply with voltage fluctuations of less than
±
10%.
Since the SRCP controller uses a capacitor input type power supply circuit, a large inrush current flows when
the power is turned on. Do not use fast-blow circuit breakers and fuses. For the same reason, avoid turning the
power off and on again repeatedly in intervals of less than 10 seconds. This could harm the main circuit ele-
ments in the SRCP controller.
