STEP CIRCUIT OPERATION
EJECTING BALE.
1.
When bale chamber is sufficiently full, resistance to compression will prevent rear trip dog from closing
VE1 and will create enough pressure in press ram to activate DW. HE2 is closed by forward trip dog. DW
energizes timer X and relay SS.
2.
Power to SV is cut and pressure on lamp KLP is lit by SS. Timer X cuts power to MW. Closing of SS
contacts enables ram forward HTP. Relay cuts power to MP and SV, shutting down cutter blades and
press ram.
3.
To prepare for bale ejection, rear gate is opened. This closes baling safety switch KS.
4.
HTP is depressed by operator. HTP was enabled by closing of SS contacts. HTP bypasses normal effect
of timer X and directs power to move press ram forward. It is kept depressed until bale is ejected and VE2
and P1 are tripped by rear trip dogs.
5.
P1 cuts power to MP and energizes timer X. Timer X contacts 31-32 open, cutting power to MW. SS
remains energized as long as VE2 is tripped. P1 interrupts power to MP so press ram will stop. P1
enables operation of switch HT.
6.
HT is depressed by operator. Power is inputted via HE1-B and HT to energize MP. MW remains de-
energized, so press ram moves in reverse. As press ram moves back to start position, trip dogs clear HE2,
VE2, and P1. When VE2 opens, power to SS will be cut, disabling HTP and shutting off KLP.
7.
Press ram returns to start position, ready for new cycle.
PRESSING CUTTER REVERSE SWITCH (RT).
Power flows through cutter forward switch AT and the NC side of cutter OFF switch VT to the cutter reverse relay
SR. As long as RT is pressed, cutter motor turns in reverse. SR contacts 31-32 open to prevent any activation
of SV while SR is energized.
PRESSING ON/OFF SWITCH (AT).
Cuts all power to portion of circuit with cutter motor relays.
