CARRIAGE CONTROL SWITCH
The CARRIAGE CONTROL switch is a three position type switch with the
Following settings:
RAISE
- raises the carriage until the top limit switch on the tower is attained.
LOWER
- lowers the carriage until the bottom limit switch on the tower is attained.
This switch is normally positioned in the middle where the carriage remains stationary.
Turning to the RAISE or LOWER will activate the carriage to move in its respective
direction.
TURNTABLE (ROTARY TOWER) JOG
The Turntable (Rotary Tower) Jog switch is a pushbutton which will rotate the turntable
(rotary arm) in a clockwise direction (as viewed from the top) when is held depressed. When
the switch is released the turntable (rotary tower) will stop. The switch is inoperative during
the wrap cycle.
FILM TENSION
Film tension may be adjusted using the Film Tension Control Knob. It has a range of tension
from 0 to 10: low range from 0 to 4, 4 to 8 is the most useful1 range for most of the films
used by our customers and 8 to 10 considered as a very high range which may break some
films).
NOTE: Lighter loads may require lower tension settings then heavier loads.
Film tension is controlled through the dancer bar sys tem Occasionally the Feed Back
Proximity Sensor may need some adjustment. Adjustment of feed back is shown on drawing
# 001.
Adjustment instructions:
- remove the carriage cover
- unbolt the two nuts holding the proximity switch (item # 1)
- turn the Proximity sensor (item # 2) until the moment when the motor starts to turn (or hums)
- tighten on the nuts securing the Proximity Sensor.
NOTE: The condition in which the motor hums but does not turn must be maintained even
after all elements are tightened. If not, the adjustment procedure must be repeated.
CARRIAGE SPEED
There are two carriage speed controls on the panel:
CARRIAGE SPEED UP & CARRIAGE SPEED DOWN
The carriage speed controls can be used to control the amount of overlap the film will have
on itself during a wrap. It is recommended to start with a RAPID upward wrap in order to
stabilize the load early in the cycle.
The control potentiometers have settings from 0 to 10, the higher settings being the fastest.
High settings will mean less film overlap because of faster carriage speed, and low settings
will mean more film overlap because of lower carriage speed.
