Emergency Stop Button

5-1 Description of Key pad’s function on the control panel

No. of Upper Layers Counted:

Displays the number of completed upper layer wrapping cycles. Screen should be blank prior to

start of wrapping cycle. When wrapping cycle begins, for each completed upper layer wrapping

cycle the number increases by 1. When number of upper layers counted reaches the number of

upper layers set, the film-seat will start descending.

No. of Upper Layers Set:

Displays the number of wrapping cycles set for the upper layer.

Cycle Setting of Upper Layer:

Sets the number of upper layer wrapping cycles. Press “▲” once increases wrapping cycle by 1 and press “▼” decreases wrapping cycle by 1. Wrapping cycle can be set to 9 as maximum, however

usually is set between 2-5 depending on different needs. Please note that wrapping cycle can not be

set to 0, as to lengthen the life span of the elevation motor.

No. of Lower Layers Counted:

Displays the number of completed lower layer wrapping cycles. Screen should be blank prior to

start of wrapping cycle. When wrapping cycle begins, for each completed lower layer wrapping

cycle the number increases by 1. When number of lower layers counted reaches the number of

lower layers set, the film-seat will start ascending.

No. of Lower Layers Set:

Displays the number of wrapping cycles set for the lower layer.

Cycle Setting of Lower Layer:

Sets the number of lower layer wrapping cycles. Press “▲” once increases wrapping cycle by 1 and press “▼” decreases wrapping cycle by 1. Wrapping cycle can be set to 9 as maximum, however

usually is set between 2-5 depending on different needs.

Motion Indication:

For detail, refer section 5-5.

Turntable Speed Adjuster:

Turntable speed can be adjusted between 0-13rpm. This function should be used in conjunction

with the Film-seat Speed Adjuster, refer to Film-seat Speed Adjuster section for more detail.

Film-seat Speed Adjuster:

Film-seat speed can be adjusted between 0~3m/min, either quicken or slower film-seat elevation

speed for desired level of film overlap. When wrapping a test package, adjust turntable speed to

maximum 13rpm and film-seat to maximum 3m/min, then when wrapping completes study the level

of film overlap for further adjustment. If a higher level of film overlap is desired, slower the

film-seat speed; if a lower level of film overlap is desired, slower the turntable speed.

Power Switch:

Main power switch with a safety device. When switch is turned "ON", the switch will jam the

control panel door and prevent it from being opened to provide safety. Please note that if the control

panel door is to be opened this switch must be turned "OFF", or else if the door is forced open when

switch is at "ON" position, the switch will break. If the power switch is broken in such a manner, it

can not be replaced free of charge even if still under warranty.

Emergency Stop Button:

In case of emergency, press this button to stop the operation of the machine and the power will

automatically be turned off. Pull this button to deactivate the emergency stop.

Pre-stretch Unit Ascent Key:

This key is used to manually control the pre-stretch unit to ascent while the machine has stopped.

Press this key; the pre-stretch unit will go up. Release it, the pre-stretch unit will stop immediately.

Pre-stretch Unit Descent Key:

This key is used to manually control the pre-stretch unit to descent while the machine has stopped.

Press this key; the pre-stretch unit will go down. Release it; the pre-stretch unit will stop

immediately.

5-2 Wrapping Function Control

『Turntable Start』:

Starts the turntable rotation, motor will stop automatically when wrapping is

completed.

『Film-Seat Pause Button』:

When wrapping a particular section of the package that needs extra overlapping

of film to give strength, press and hold this button for the film-seat to pause at

the desired section of overlapping. When the operator is satisfied with the

amount of overlapping, release this button and the film-seat will continue its

ascending/descending.

『Turntable and Film-seat Zero-return Button』:

This button has two functions:

1: It can be used to determine the height of package in case of malfunctioning

of the electronic eye. When electronic eye malfunctions, the film-seat can not

sense the height of the package and will continue to ascend, in which case by

pressing this button the film-seat will cease ascending and start counting number

of upper layer wrapping cycles. Also press this button if the film wrapping

reaches a particular height of the package and further more wrapping above is

not desired.

2: If the emergency button is activated during wrapping, the turntable and the

film-seat will not be stopped at the starting position. Therefore in order for both

the turntable and the film-seat to return to their starting position, press this

utton once for turntable to return to starting position and press again for

film-seat to return to starting position.

『Standard Wrapping』:

Film starts wrapping from the bottom of the package to the top, and once from

top back to bottom。

『Single Layer Wrapping』:

Film wraps once from bottom to top and stops when turntable comes to a halt.

Film set then automatically descends down to starting point.

『Water Proof Wrapping』:

Film wraps from bottom to top and then comes to a halt at

approximately 10cm~15cm below the top of the package, then a sheet of water

proofing film or plastic should be manually placed on top of the package. Press

the Turntable Start button once more to restart the wrapping process, at which

the film will start wrapping from top back to bottom.

F:\Manual\SM-1517R-110V-100514 14.05.2010.

- 16 -

『Midpoint Strengthen Wrapping』:

Film wraps from bottom to top and completes the upper layer wrapping cycle.

When returning from top back to bottom, film set will pause at the midpoint of

the package to complete 2 wrapping cycles and then back to bottom to

complete wrapping.

7 Film Tension Adjust

The pre-stretch unit has a set pre-stretch percentage of 240% (can not be changed) which is called the First Stage Pre-stretch, therefore there is no pre-stretch setting device on the control panel. The pre-stretch percentage can be slightly adjusted to a maximum of 320%, which is called the Second Stage Pre-stretch, and its adjusting method is shown below:

There are 2 sets of nuts and bolts located on the top and bottom of the free roller and is used to adjust pre-stretch ratio.

Pull away the free roller and 2 springs can be seen attached to the 2 sets of nuts and bolts.

Slightly tighten the nuts onto the bolts to pull on the springs in order to increase pre-stretch ratio.

Warning: Do not pull on free roller while pre-stretch unit in operation, as not to cause film

jamming into rollers.
