Board Sensor Sensitivity Adjustment
Upward-facing Board Sensors (X-1010 only) or downward-facing Board Sensors (X-1020 only) are
optical sensors located along the length of the front Conveyor Rail. The Sensors detect the presence of
the workpiece and report it to the Conveyor Controller. Board Sensor sensitivity should be adjusted after
initial installation and if the sensors are failing to sense the presence of a workpiece.
Upward-facing Board Sensors (X-1010 only)
Sensitivity adjustments for upward-facing Board Sensors are made on the back of the Sensors which are
located under the Front Conveyor Rail. Depending upon system configuration, there may be as many as
two Board Sensors (pre-dispense and dispense station).
CAUTION! The following procedure should only be performed by a trained
service technician.
Tools and Materials Needed
• Flat Head Screwdriver
• Production Sample Workpiece
To adjust upward-facing Sensor sensitivity:
1. Locate the Board Sensor under the front Conveyor Rail and find the Adjustment Screw and
red LED on the rear of the Sensor. See Figure 6-7.
> If the LED on the Sensor is difficult to see, the action of the Board Sensor can be
monitored on-screen as follows:
a. In the FmNT Main Window, click on
Tools, then I/O Test, then on Conveyor.
b. In the MPC 555 I/O Diagnostic dialog box, click on the
Station I/O Diagnostic tab
and note the “Board Present” line for the Conveyor Station being tested. The bit on
the Board Present line will indicate ON when a board is present and OFF when no
board is present.
2. Using FmNT Jog Controls, move the Dispensing Head over the sensor being adjusted.
TIP The Dispensing Head should be at the Z-home height and in production
configuration with all Dispensing Valves and Height Sensor installed.
3. Open the Hatch and adjust Board Sensor far distance sensitivity as follows:
> If the red LED is ON (or the “Board Present” bit says ON), slowly turn the adjustment
screw counterclockwise until the LED just turns OFF (or “Board Present” bit just
changes to OFF).
> If the red LED is OFF (or the “Board Present” bit says OFF) proceed with Step 4.
