8 - Main Air Pressure Fault
A pressure sensor monitors the air pressure supplied to the feeder.
If the air pressure falls below the pressure set point (50PSI / 345kPa), a Main Air Pressure Fault
will occur.
The fault can be reset by increasing the air supply pressure to the feeder and then pressing the
blue Fault Reset pushbutton.
The main air pressure switch is mounted inside the electrical enclosure on the left side wall.
9 - Safety Bumper Fault
The safety system includes six safety bumpers. (See Section 4.3)
A Safety Bumper Fault will occur whenever any of the safety bumpers is pressed.
Pressing any of the safety bumpers will cause the safety relay to be de-energized.
10 - Feeder Travel Limits Interference Fault
Vertical and Horizontal Travel Limits are used to set a protective zone that prevent the forward
suction cup arms from colliding with the forward stack guides, the support table or the
electrical enclosure beneath the support table.
See section 8.9.2.1 for more information.
A travel Limits Interference Fault will occur whenever the carriage and gantry are moved into
the interference zone as set by the travel limits.
To remedy, jog the carriage and gantry out of the interference zone.
11 - Feeder Plunger Sensor Stuck Fault
The proximity sensor mounted on the first suction cup compensator is called the plunger
sensor.
The plunger sensor is used to detect when the suction cup has contacted the board stack to
determine the stack height.
The plunger sensor detects a target washer when not activated.
The control system will check to see if the sensor is in the non-actuated position at the
beginning of a Pick Cycle, and at the beginning of lowering the board to the support table. If
the plunger sensor is not detecting the target at the beginning of each of these cycles, then the
plunger is stuck, and a Plunger Sensor Stuck Fault will occur.
Remedy: check to see that the plunger sensor is detecting the target washer, and that the
suction cup compensator is moving freely.
The plunger sensor has a maximum detection range of 1.5mm. Set the face of the sensor to a
distance of ½ mm away from the target washer.
