SIDE NOTE
Have the belt drive position switch (fig. 19) in the zero
position, and also have the trimming switch on, this will
produce the desired light configuration. When the switch is
turned off there are no lights lit.
If holding the reset button down, L8, L16, and L19 will also
be lit. If only pushed and released, the previously mentioned
lights will only momentarily light. Both of these previously
mentioned conditions remain true for any subsequent start/
reset thereafter.
If the emergency stop button is twisted back into the nominal
position, the lights will display as in process number 1.
If the trimming switch is on, the lights will look the same as
in process 2. If the switch is off, the same is true but L1 is
also lit.
If holding the button down, the knife will cycle up and down
and the following lights will light. L2, L3, L6, L7, L10, L13,
L16, L17, L18, and L20 (L3 and L7 will flash on and off
simultaneously).
Starting at position 1: L4, L5, and L9 will be off. At position
2 L4 will turn on. At position 3 L4 will turn off and L5 will
turn on. At position 4 both L4 and L5 will be on. At position
5 L4 and L5 will be off and L9 will turn on. At position 6 L4
and L9 will be on.
If the lid is returned to the closed position, the lights will
display as in process 1.
Inputs: L6 first turns off and then relights. This is closely
followed by L7 turning off, and then L3 turning off. Outputs:
L17 turns off immediately followed by L20 turning on then off.
This is followed by L16, L17, and L19 turning on and then
L16 and L19 quickly turn off together. When done the light
pattern should be that of process 2.
Covering the front infeed photosensor will turn off L6. If L6
is covered for approximately 5 seconds, the machine
perceives a jam and L3, L7, L13, and L18 turn on.
Covering the gate photosensor will turn off L7. The
operational light sequence will follow that of process 8, but L6
will not relight before L7 turns off. Therefore if L6 and L7
are out together, all lights turn off except L3, L13, and L18.
A jam occurs when both the gate and infeed photosensors
are covered at the same time.
If the machine is on and running but not being used for
about 2 minutes, it will auto shutdown. L10 and L17 will turn
off, and L13 and L18 go on.
