2.5.4 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-
24
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 EFD
®
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.
