a.
Operation switches. Used by the operator to activate or deactivate the cutting blades and/or press ram. Main
power switch (Q) controls power to the entire machine. Cutter FORWARD (S2), REVERSE (S4), and STOP (S3)
switches direct power to the relays that control the cutter motor. Bale ejection switch (S11) controls the ram during the
ejection of a bale.
b.
Limit switches. Direct power flow for energizing and deenergizing the relays. These switches are opened and
closed as the ram moves. Pump motor control limit switch (S9) controls power to the pump motor relay (K3). Ram
stroke limit switch (S10) controls power to timer relay (K4). Solenoid valve control limit switch (S12) controls power to
control contactor relay (K5) which positions the solenoid valve.
c.
Relays. Direct power as follows:
Cutter forward relay (K1) directs power to drive the cutter mechanism forward.
Cutter reverse relay (K2) drives the cutter mechanism in reverse.
Pump motor relay (K3) directs power to the pump motor.
Timer relay (K4) directs power to the solenoid valve and to the control contactor relay (K5).
Control contactor relay (K5) directs power to the solenoid valve and timer relay (K4).
d.
Safety switches (safety connector switch, folding switch, and emergency stop switch). Interrupt or change the
normal flow of power through the control system to prevent operation of the shredder-bagger under conditions which
could damage it or harm the operator.
e.
Indicating lamps. Light to indicate the operational condition of the shredder-bagger. Power on lamp (Hi)
lights when the control system has power. Bale chamber full lamp (H2) lights when the bale being compressed is under
pressure and when the bale is ready for ejection.
f.
Protective fuses and circuit breakers. Provide overcurrent protection for the motors and the control system.
Fuse Fl will blow to prevent overcurrent conditions to the control system. Protective circuit breakers F2 and F3 will trip to
protect the cutter and pump motors.
