3.1.2.1 Fan (Figure 3.2 Item 1)
The fan keeps the devices in the Controller Module from getting too hot. Make sure the area around the fan is clear of
obstructions.
3.1.2.2 AUX OUT Terminal Strip (Figure 3.2 Item 2)
The AUX OUT (Auxiliary Output) terminal strip has two screw terminals (+/-) used to enable auxiliary equipment.
Refer to section 3.3.10.2.
3.1.2.3 CC TRIG Terminal Strip (Figure 3.2 Item 3)
The CC TRIG (Contact Closure Trigger In) terminal strip has two screw terminals (+/-) used for triggering operation in
Production Modes. Fluidic Setup Mode operations can not be initiated with this signal. Refer to section 3.3.10.1.
3.1.2.4 RS232 Connector (Figure 3.2 Item 4)
The RS232 interface provides control of all available functions. The hardware is configured as Data Communications
Equipment (DCE) standard. Refer to section 3.3.11.
3.1.2.5 AUX COMM Connector (Figure 3.2 Item 5)
The AUX COMM (Auxiliary Communication) connector will be used for a future enhancement.
3.1.2.6 LOGIC I/O Connector (Figure 3.2 Item 6)
The Logic I/O connector is used for making the electrical connection to the LOGIC I/O Interface Device. Refer to
section 3.3.10.3.
3.1.2.7 MOTOR Connector (Figure 3.2 Item 7)
The Motor connector is used for making the electrical connections to the Actuator Module.
CAUTION
Never connect or disconnect the cable from this connector while power is on. Damage to the equipment
may result.
3.1.2.8 Power Entry Module (Figure 3.2 Item 8)
The power entry module contains a receptacle for a standard IEC power cord, an On (1) Off (0) switch, fuse holder
and fuse.
The design of the power entry module requires the line cord be disconnected before the line fuse is removed. Refer to
the Title Page section for fuse information.
3.1.3 Fluid Movement
Fluid movement in the system is achieved by the displacement actions of the pump. A piston moves forward and
reverse in the pump chamber moving fluid in and out of ports. The piston rotates to move a flat on the piston between
the two ports (Port A and Port B) to achieve the desired fluid movement through the system. The movement of the
piston is initiated by an Actuator Module driven by a motor. The Controller Module provides the control and power to
the Actuator Module's motor to achieve the desired fluid movement.
