1128600 SmartPAC 2 with WPC 2000 Integration User Manual
6-12 Run Mode
To clear the actuation angles displayed for a sensor, press the F5 (Update the Sensor Arc)
function key. If the press is stopped, the Sensor window displays zeros. If the press is
running, SmartPAC 2 displays the actuation angles for the next stroke.
Pressing F4 (Change Reference Angle) changes the reference angle used to determine
earliest/latest On and Off signals from 0
°
, the default, to 180
°
. Executing this function may be
necessary to correct On readings for green and green quick check sensors that actuate before
and stay actuated after TDC. When 0
°
is the reference angle, there can be no earliest On angle
for a sensor that turns on before and off after 0
°
since angles just before TDC (e.g., 330
°
) are
numerically greater than those just after TDC (e.g., 30
°
). You should press F4 whenever the
On/Off settings in the Sensor window do not match the start and end points of the green
actuation arc on the clock diagram.
To adjust the Ready signal for green sensors, do the following:
1.
On the Die Protection Menu, select the desired sensor. The Ready Signal Programming
screen displays.
2.
Run the press.
3.
Observe the On and Off angles displayed in the Sensor window and the green actuation
arc shown on the crank angle clock.
Pressing F5 will not properly update sensor actuations when you are using a mechanical sensor,
which vibrates constantly during the stroke. It is better to use an electronic sensor, which is not
prone to constant contact bounce.
IF YOU DO NOT KNOW READY SIGNAL TIMING FOR GREEN SENSORS
If you are unsure of when the sensor turns on and off, program estimated settings in Program
mode, load the tool, and turn off the sensor, using the SENSOR ENABLE/DISABLE & STATUS
item on the Main Program Menu (see page 5-53). Turning the sensor off prevents nuisance stops
when you switch to Run mode.
Then,
without reloading the tool,
turn the Program/Run switch to RUN and perform the procedure
shown below. When you are finished adjusting settings in Run mode, go back to Program mode
and turn the sensor back on.
If you have turned off the sensor in Program mode (see page 5-53), a message displays
indicating that the sensor is turned off (see Figure 6-13, page 6-10). Press ENTER to
clear the message.
