Mounting the Pump

Procedure Attach the mounting bracket to the Z-axis plate as follows:

1. Loosen the four socket head cap screws that secure the Z-axis mount assembly

to the pump and remove the mount assembly. The socket head cap screws are

held captive by cross-point screws.

2. Align the bottom edge of the mount assembly as flush as possible with the bot-

tom edge of the A-axis mounting plate.

3. Using two socket head cap screws and washers, secure the mount assembly to

the Z-Axis mounting plate.

Attention

The lower edge of the pump body should always protrude past the bottom of the Z-

axis slide when in place.

4. Assemble the pump to the Z-axis assembly mount so that the two locating pins

on the mount engage in the pump body.

5. Secure the pump to the mount with four socket head cap screws.

Introduction The 680SD incorporates a precision mechanism which raises the leadscrew to allow

the flow of material through the needle when a dispense command is executed. At the

end of the dispense cycle the leadscrew is lowered, sealing off the end of the needle

preventing material seepage. Two air connections are required for each pump. One

raises and the other to lowers the leadscrew.

Procedure Air pressure to P1-P4 is factory preset to 60 PSI (max). This air supply is used to open

a valve (P1, P3) during dispense and close it (P2, P4) after dispense. Connect to the

dispense panel using the appropriate quick disconnect fittings as follows (see Figure 1

and Figure 7)

• P1= Right Primary Valve Open

• P2= Right Primary Valve Close

• P3= Left Secondary Valve Open

• P4= Left Secondary Valve Close
