4.2.3
Hydraulic pump power loop components
The hydraulic pump M1 is powered by 3 phase 220V AC through KM1 contactor and protected
by QM1 circuit breaker.
a) Circuit breaker - QM1
QM1 interrupts the 3 phase power to the hydraulic
pump motor. It is also connected in the emergency
stop circuitry. If the motor overloads (the breaking
current is set to 2.5 amperes) the circuit breaker trips
from ON to OFF. Both power supply to hydraulic pump
and the emergency stop loop are interrupted. After the
problem is fixed, reset the circuit breaker by switching
to ON.

C
b) KM1
The KM1 contactor is energized by 24V DC from PLC
output Y03. When this signal is OFF, the KM1 is
de-energized and the power to hydraulic pump is cut off.
4.2.4 PLC and 24V DC supply power loop component
Breaker QF2 protects the two phase which powers both
PLC and 24V DC power supply. If the power exceeds
4A, the breaker trips and lever B flips down. The power
supply to the PLC and 24V DC power supply is
immediately interrupted.
After the problem is fixed, reset the breaker by flipping
lever B up.
