1.7 Front View Features
The figures in this section show views and features of the dispensing system. Callouts locate major
components, options, and switches seen in each illustration. Detailed operating instructions for some of
these features are treated in other sections of this manual. Front view features are shown in Figure 1-3.
Z-Head Dispenser Connections
All dispensing valves and dispensing options mounted to the Z-axis are connected through this area.
Cable Track
The Cable Track houses electrical cables and pneumatic tubing to the Z-head.
Start Button
The Start Button puts the dispensing system in a power-on state.
Off Button
The Off Button shuts off power to the dispensing system during normal operations.
Emergency Machine Off
The Emergency Machine Off (EMO) button is a built-in safety feature located on the front panel of the
dispensing system. Refer to Section 2 - Safety for additional information.
ESD Grounding Strap Connector
Grounding Straps worn by the operator or technician plug into this jack to prevent electrostatic discharge
(ESD) damage to workpieces and dispensing system electronics during dispensing operations and
servicing.
Vacuum Control
The Vacuum Control allows low viscosity fluids, even water, to be consistently dispensed without dripping
between cycles. The vacuum exerts a negative pressure on the fluid pressure pneumatics line when the
valve is turned off.
Fluid Pressure Regulator and Gauge
The Fluid Pressure Regulator and Gauge set supplies very precisely regulated air to the fluid syringe.
Valve Air Pressure Regulator and Gauge
The Valve Air Pressure Regulator and Gauge set supplies regulated air pressure to the dispensing valve.
Computer System
The Computer System (Figure 1-6) consists of a laptop PC and connecting cables. An external mouse is
also provided for your convenience.
