Set the command value for TM so that the DC
voltage is present for 100 % after elapse of time.
The DC power supply for the input signals is
switched on, when the timer TM stops and the DC
voltage is present.
MC is switched by RA1 when the CPU is in mode
RUN.
Voltage relay is recommended at RA2
Low battery alarm (Lamp or buzzer)
RA1 switches on if there is no error message from
the power supply.
The outputs are switched off by MC when the CPU
is in mode STOP
Interlock circuits as necessary. Provide external
interlock circuits for conflicting operations, such as
forward rotation and reverse rotation, and for parts
that could damage the machine or cause accidents
if no interlock were used.
