4.3.8 Inlet and Outlet Interfaces

4.3.9 CCS Retro-Reflective Sensor VXP/VXP+ (optional)

Fig. 4-17 Inlet / Outlet Interface

The peripheral devices at the sys-

tem’s inlet and outlet is integrated

via these interface.

Interfaces from various manufactur-

ers are utilized depending upon the

respective requirements. Smema

and Siemens interfaces are avail-

able as standard equipment.

Fig. 4-18 CCS Sensor

If Capability Control System (CCS)

is mounted, the inlet light barrier is

used as start signal for measuring

points.

The sensor must be cleaned at reg-

ular intervals.

The inlet sensor must not be mis-

aligned.

The sensor must be cleaned reg-

ular.

4.3.10 Center Support

The center support prevents the PCBs from sagging as a result of exposure

to heat.

The position of the CS

is entered directly to the PC as a setpoint (see

Fig. 5-11 Main Window, on page 85.).

Safety limit switches prevent violation of minimum and maximum values.

If the CS is not needed, it can be advanced to the parking position. The park-

ing position is at the fixed side panel.

1. CS = Center Support

Fig. 4-19 CS Leaf Chain

The PCBs are supported by the leaf

chain which is guided via an alumi-

num profile rail during transport

through the system. The center sup-

port and the chain conveyor are op-

erated synchronously.

Lash chain is led back outside pro-

cess chamber, under the oven.

Fig. 4-20 CS Height Adjustment

Height is adjusted by means of a

gate.

The gate is located at the mechani-

cal stations. The absolute rotary en-

coder used for acquiring travel is

next to the motor at the oven outlet.

4.4 The Process Chamber

Operating Instructions

Version 1.5

4.4 The Process Chamber

The process zone is subdivided into the following segments: inlet area,

calming region (nitrogen lock), heating chamber, cooling tract and outlet ta-

ble. The system’s modular design allows for flexible zone setups. This

means that the number of heating zones and the cooling tract can be better

adapted to the PCBs to be soldered.

Each individual segment can be opened manually for the performance of

maintenance work.

Please refer to the data sheet which is included in the documentation regard-

ing process chamber technical data. These data make reference to standard

system types, and may vary optionally depending upon provided system

equipment.

4.4.1 Opening/Closing the Process Chamber

The process chamber is opened and closed in a stepless fashion by means

of an electric motor. The entire process chamber cannot be opened manu-

ally.

4.4.2 Removing the System Hood

Fig. 4-21 Removing the System Hood

The system hoods are removed

manually.

They are opened to this end with the

appropriate wrench and then lifted

out.
