General Procedures & Information
GP 16 How to Safely Lift or Move Heavy Modules
Purpose
Use this procedure when lifting or moving heavy modules.
Procedure
WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord from the
customer supply while performing tasks that do not need electricity. Electricity can
cause death or injury. Moving parts can cause injury.
WARNING
Take care during this procedure. Sharp edges may be present that can cause injury.
When removing heavy modules from the machine, the following instructions must be observed:
1. Ensure that a suitable stable surface to support the module after removal is located in
close proximity to the machine.
NOTE: Other parts of the machine are not a suitable stable surface.
2. Ensure that the height of the support surface is between 750mm and 1000mm (30 inches
and 39 inches).
3. Ensure that there are no hazards or obstacles between the machine and the support sur-
face.
4. If instructed to remove the module toward the rear of the machine and only one person is
available, the module must be removed while standing at the rear of the machine. If two
people are available, the module may be removed while standing at the front of the
machine.
5. Two people are required if the module is to be lifted on to the floor or lifted from the floor.
GP 17 High Frequency Service Items
Purpose
To provide the service engineer with a method to view the service history of the high frequency
service items (HFSI). The service engineer can reset the counters and change the setting of
the maximum life and threshold value of each HFSI item.
Procedure
Enter diagnostics GP 1. Select the Service Info window and touch the HFSI feature to select
the HFSI table.
The five columns in the HFSI table on the display are:
• The Item column, shows the HFSI item to be tracked.
• The Status column, indicates the status of an item relative to its threshold setting. Values
are “Off” (not tracked), “OK” or “Check”.
• The Unit column, shows the events that are being used to track the item.
• The Actual column, shows the actual count value against the HFSI item.
• The Max. Life column, shows the maximum life count value of the HFSI item.
The Actual and Maximum Life count value have a numeric range of 0 to 9999999 for all HFSI
items.
The first item in the HFSI table will be the item that requires attention (if needed) then the item
will be displayed as “Check”. If the item has not yet reached threshold the “OK” is displayed.
To change the maximum life or threshold value of each HFSI item, perform the following:
1. Select and highlight the HFSI item to change.
2. Touch the Edit button.
3. Enter the new value using the numeric keypad. The new value will overwrite the existing
value in the table. Touch the Save button to enter the new maximum life or threshold
value into the file. If the entered value is incorrect, press the Undo button. This stops the
process and the old value is retained.
A threshold value of zero indicates that there is no threshold value assigned to the item and the
status will be “Off” (not tracked).
The maximum life setting and the threshold settings are independent of each other. The
threshold value can exceed the maximum life value.
To reset the HFSI item Actual count value to zero, perform the following:
1. Select and highlight the HFSI item to reset.
2. Touch the Reset button,
3. Touch the OK button to reset the count value to zero.
