Table 4-4 Local Machine Offset Options
Command Description
Heater Offsets
Tab
Heater offset is the actual temperature measured at the tooling on different
machines for a given input (use of temperature measuring device is necessary to
get the actual temperature). Once the offset is learned (Machine 1 vs. Machine 2), it
is used to adjust the temperature as needed.
Enable Local Machine Heater Offsets: If checked, the system uses the previously
taught input reading offset. The input reading offset specific to this dispensing
system is used in place of the offset embedded in the program.
Current Offsets for Heater 1 (or 2): Displays the name of the heater file associated
with the currently loaded program.
Edit: Allows you to edit the previously taught input offset reading.
Workpiece
Origin Tab
The Workpiece Origin (WPO) on a machine is its position in the work envelope
relative to machine Home (0, 0). This relative location varies on every machine.
Local Machine Offsets identifies that difference and uses it as a correction factor for
all locations in that program. This allows each machine to dispense accurately.
Enable Local Machine Workpiece Origin: = If checked, system uses the previously
taught workpiece origin. When you run a dispensing program while this feature is
active, the workpiece origin specific to this dispensing system is used.
Workpiece Origin: Allows you select from a list of previously created origins.
Edit: Allows you to edit the previously taught workpiece origin, create a new
workpiece origin, or delete a workpiece origin.
Height Sense
Tab
Enable Local Machine Height Sense
- If checked, the system uses the locally taught
height sense for a specific lane. When running a dispensing program while this
feature is active, the height sense specific to this dispensing system is used.
Valve Bias Tab
No two valves dispense exactly alike, especially when used on different machines.
Once a valve identifier is established (usually valve model number and serial
number) and it is paired with a fluid file and a flow rate measurement is taken, the
valve speed is adjusted as necessary until the flow rates on both machines are the
same. A sample dispense run (usually a 30-slide test) is performed to determine the
offset between the programmed weight and the actual dispensed weight. This offset
becomes the bias.
Enable Local Machine Valve Bias: If checked, the system uses the previously taught
valve bias. When this feature is enabled, the valve bias specific to this dispensing
system is used.
Valve 1 Identifier: Identifies which valve is currently installed as Valve 1. Click on the
arrow next to the box to activate the drop-down menu listing all available valves.
Valve 1 Fluid File: Name of the fluid file associated with Valve 1.
Valve 2 Identifier: Identifies which valve is currently installed as Valve 2. Click on the
arrow next to the box to activate the drop-down menu listing all available valves.
Valve 2 Fluid File: Name of the fluid file associated with the Valve 2.
Edit: Allows you to establish valve identifiers, set bias limits, and attach fluid files.
Air Pressure
Tab
Air pressure for a given set value can fluctuate slightly from dispenser to dispenser.
This tab provides a +/- offset that can be used to adjust the set value or reading
value to the actual measured pressure for Cooling, Active, Valve or Fluid air
pressure. Use this tab when sharing recipes between dispensers to ensure
consistent air pressures.
Maintenance
Tab
Allows you to establish the number of days the Local Machine Offsets are valid.
This ensures that the offsets remain accurate.
Edit number of days Local Machine Offsets are valid: Click on Edit to establish a
time frame for checking Local Machine Offsets to ensure that they remain accurate.
