ELECTRIC AUGER VALVE

Install the Auger valve onto its corresponding valve bracket (P/N 700806)
before attaching onto the T-slots of the Z-carriage.
The Auger valve uses a brushed DC motor and requires two electrical
connections into the 4-position
terminal block located on top of
the Z-Head. The positive (+)
white wire goes to terminal 1
and the negative (-) brown wire
goes into terminal 2.
If the white and brown wires are
connected inversely, the motor
will run in reverse. The Auger valve will not dispense fluid while the motor is running backwards. If
the valve is not dispensing but the motor is turning, check fluid pressure and ensure the wires are
plugged into the proper terminal.
The syringe barrel adapter quick-connects into the P2 connector on top of the Z-head. The fluid
pressure can be set to pulse with the valve or remain constant. This setting is made in the valve
setup (options window). The Ultra TT system also allows you to set parameters to turn off fluid
pressure when the system is idle to prevent separation of solder paste.
The valve speed is selected as a voltage ranging from 10.0 VDC to 24 VDC in 0.1 VDC increments.
This setting is made in the valve setup (options window). Maximum 250 RPM with a 400 RPM
option (for 792 valve) are provided with either an 8 or 16 pitch auger. Once the voltage has been
selected, the Back EMF circuit will maintain a constant RPM.
