XIT6000-CA
3/8” Tie-Lok ® Tool
Tool Overview
Tool Function:
The XIT6000-CA tool functions by using an incoming supply of air to actuate a mechanical
linkage. The linkage connects to a gripping system that outputs a force on the band portion
of the Tie-Lok ties. The output of the tool varies depending upon the air pressure supplied
to the tool. If the pressure is increased, the output force increases.
During the tension cycle the tool will continue to pull up or tension the band until the
appropriate tension is reached. The tool stops tensioning when the pressure in the tension
cylinder equals the inlet tension pressure coming from the air controller module. After the
tool has pulled tensioned the tie, the tool switches over to the cutoff cycle. At this point in
the cycle the gripping system maintains the force on the tie and a knife is actuated down
which forms a dimple and cuts the band.
Equipped with the tool, there is a tension cylinder pressure monitor (Red/Green Light Data
Acquisition) that measures the air pressure in the tension cylinder when the tool switches
over to cut-off. The pressure is captured from the tension cylinder immediately before
cutoff, while the tension force is being held in the band. The electronics of the tool takes this
pressure reading and calculates a number for the output force based upon an equation.
This equation is derived from a capability study of a normal XIT6000-CA tool fitted with a
M28090 calibration device (see Tool Calibration, page 37) at the initial build of the tool.
Pneumatic System:
The pneumatic valves and cylinders all have seals or o-rings that wear out. Once the o-
rings in the cylinders begin to wear, air is allowed to pass by the pistons in the cylinders,
which can affect the performance of the tool and cause the calibration of the tool to drift.
The cylinders are permanently lubricated, but premature wear can be caused by debris in
the air lines or the presence of water and oil, which can break down the lubrication. The 4-
way valves in the tool can be affected by debris and oil in the air lines that cause the valve
to stick and not operate as is necessary. Over time, the mechanical linkages in the tool will
also begin to wear. This wear will cause some drift in the calibration of the tool, but does not
have the same effect of wear in the air system.
To address the potential problems associated with the air supply, BAND-IT recommends the
use of an Air Booster System. In addition to filtering and drying the air, it will also maintain a
steady pressure of 100 -110 PSI assisting the proper function of the tool.
