The Gun Stroke Limit screen displays items for setting the stroke limits of the gun axis. Changes to these items take effect immediately. In multi-gun systems, use the EQUIP and GUN keys to switch between equipment and guns. Press the END key to exit the screen. Table 7, " Gun Stroke Limit Screen Items " lists and describes the Gun Stroke Limit screen items.
Table 7. Gun Stroke Limit Screen Items
ITEM | DESCRIPTION |
---|---|
Open stroke limit (mm) |
This item is the maximum open distance allowed for the gun, measured
from the reference zero position. This may be directly specified by the gun
manufacturer, or it may need to be measured. Always enter a positive value.
The reference zero position is where the gun tips touch with new tips. If tip wear compensation is used, the reference zero position is where new tips touched at the time of tip wear initialization. If tip wear compensation is NOT used, the stroke limit is the distance the gun tips can open from the present zero position. |
Close stroke limit (mm) |
This item is the maximum travel allowed for the gun tips in the
closing direction, past the reference zero position. This may be directly
specified by the gun manufacturer. Typical ranges for the value is 15-30mm.
This must be set large enough to allow for tip wear and bending of the gun
arms during pressurization. But, it cannot exceed the end-of-travel for the
gun actuator. Always enter a positive value.
The reference zero position is where the gun tips touch with new tips. If tip wear compensation is used, the reference zero position is where new tips touched at the time of tip wear initialization. If tip wear compensation is NOT used, the stroke limit is the distance the gun tips can close past the present zero position. |
