Operation Mode

The system will always power on in default

Operation Mode

with all operational parameters set as

they were during the last use. True bottle speed will be displayed along with any alarm conditions.

Setting Bottle Speed

The user can change the bottle speed during operation by pressing the

Button (top right) to

increase speed or the

Down

Button (bottom right) to decrease speed at any time. The

button will

increment the bottle speed by 0.01 rpm with each press and the

Down

button will decrement the

bottle speed by 0.01 rpm each press. Holding either button down for about 5 seconds will allow for
faster display value changes when a larger numerical change is required.

The standard bottle speed range for this system is 0.23 rpm to 8.02 rpm (using 110 mm diameter
bottles).

Setup Mode

Pressing the

Select

button (top left) once enters the

Setup Mode

. The

Setup Mode

is used to set the

bottle diameter and direction of rotation. Once set, these parameters are usually not changed unless
different size bottles are used. Values set in the

Setup Mode

are not erased when power is removed

from the system.

To change a parameter value, press the

Select

button until the desired parameter is displayed. Press

the

Enter

button and the display will show the existing parameter value. Press or hold the

button

to increase the parameter’s value. Press or hold the

Down

button to decrease the parameter’s value.

When satisfied with the value change, press the

Enter

button to save the new value to memory and

automatically return to

Operational Mode

To check a parameter value without changing it, press the

Select

button until the desired parameter

is displayed. Press the

Enter

button to display the existing value. Press the

Enter

button again to exit

the

Setup Mode

and return to normal

Operation Mode

NOTE:

If no buttons are pressed for 30 seconds, the system will automatically exit

Setup Mode

and

return to normal

Operation Mode

Bottle Diameter

The Standard Roller Apparatus system is designed to accurately display actual bottle rotation speed.
Once a bottle diameter has been programmed, the unit will automatically calculate and adjust itself
to roll the bottle correctly at its set speed. Different bottle manufacturers produce bottles of different
bottle diameters. It is not recommended that bottles of different manufacturers be mixed on the
same unit if an accurate bottle speed is to be obtained.

The Standard Roller Apparatus relies on the

maximum

bottle diameter for proper bottle speed

indications. Traction rings and any outside ridges on the bottle must be considered in calculating the
maximum bottle diameter. Carefully measure (in millimeters) the maximum diameter of a sample
bottle to be used. If traction rings or ridges are at both ends of the bottle, measure both ends and take
the average. Using the obtained measurement(s), enter the bottle diameter (in millimeters).
