The axes home in the following order: Z, W, then X & Y simultaneously.
Standby Position
Once the machine has completed the homing sequence or finishes a required calibration procedure (if so
equipped), it moves to the standby position. Standby is a defined location, DISTINCT from the home
position, although in some circumstances it may be defined as the same position as home. In most cases,
the standby position is placed near the board stop to minimize travel during Auto Cycle. The workcell
always returns to the standby position in Cycle Stop. If the standby position needs to be changed, please
consult the Main Program Modifications section of the PathMaster® Manual.
Solvent Cups
Some workcells have solvent cups installed as an option. The need for solvent cups is dictated by the
process by which the workcell will be used for. When solvent cusp are installed, the Auto Purge feature is
overridden by the solvent cup routines regardless of the Setup mode settings.
The solvent cup location varies from model to model, however, the location will be somewhere in the
workspace of the workcell. Solvent cups are used as a means of maintaining clean dispense / spray heads.
In Cycle Stop the heads are situated in the solvent cups. In Manual mode, the heads are removed from the
cups and remain out until exiting this mode. In Auto Cycle the heads lift and run the auto purge routine.
They return to the solvent cups after a pre-programmed period of inactivity.
To change the time delay before the heads enter the solvent cups in Auto Cycle, change the variable
SLP_TM in the Machine-Specific Information section of the Main program. A value of 1000 equals 1000
milliseconds or 1 second.
Flow Monitor System
Some workcells have a flow monitor installed as an option. The flow monitor on the workcell measures the
amount of material moving through the material supply line before it is split to supply the individual valves.
It is used as a verification of the dispensing process, not a control of that process, and reports excessive
deviations from desired values. Both the desired material volume and allowable deviation are determined
by the operator.
Priming the Flow Monitor
The flow monitor must be primed prior to use to prevent damage to the unit. Priming the flow
monitor minimizes the amount of air that will pass through the unit during initial startup. Follow the
procedure below to prime the flow monitor.
o Fill the pressure vessel with material and seal.
o Set the material pressure regulator to 0 P.S.I.
o Turn the inlet air and outlet material valve to the closed position.
o Disconnect the material line from the inlet port of the flow monitor.
o Turn the air inlet and material outlet valves to the open position.
