Operation
Startup Procedure
1) Check the fluid and air pressures.
2) Close all doors and turn the DOOR BYPASS key switch to the OFF position (If applicable).
3) Engage the EMERGENCY STOP button.
4) Turn on main power using the red rotary switch at the front or rear of the machine (Black “rocker”
switch on PVA250™ models).
Light Tower Operation
Three stacked indicator lights and a buzzer are used to indicate the status of the machine. The lights are
green, amber, and red with green on the bottom, amber in the middle and red on top. The buzzer is located
below the green light. The lights are visible from all sides of the machine. The indicators operate as
follows.
o The green indicator is on when the machine is in cycle and producing parts. It is off at all other times.
o The amber indicator is on when the machine is in Auto Cycle and ready to produce parts, but can not
cycle due to an external material handling problem (no incoming parts or no room to unload parts).
PVA750™ and PVA2000C™ models are equipped with a light tower but not an amber light.
o The red indicator is on steady when the machine is not in Auto Cycle due to operator intervention. It
will flash when the machine is in cycle, but cycle is halted due to a machine problem. It is off at all
other times.
o The buzzer cycles with the red indicator during machine errors.

Exhaust Verification
Once the workcell has initialized, most models will perform an exhaust flow verification process. If
initialization fails, consult the section Startup Errors on page 36. During this process, and whenever the
workcell is in operation the exhaust flow rate is monitored via the on board pressure differential switch.
The workcell must exhaust at a rate no less than 150 cubic feet per minute, otherwise a critical fault will
occur shutting the motors down. The verification process will also attempt to evacuate any potential vapors
that may already exist in the work area of the workcell. The time this process takes will vary from model to
model, but the remaining time for the process will be displayed as in the screen below:
