Mechanical and electrical design

There is a cooling fan on the MCU. The fan starts up automatically when
the heat sink reaches a temperature of approx. 65

C, which can arise

during extraction if the load is unfavourable or if the ambient temperature is
high. When the machine power supply is first switched on the fan operates
for a short time.

The MCU has an interlock signal input connected to a switch in the door,
which supplies the input with main voltage when the door is locked.

PCB connector/Function

X301: Serial communication

Communications between MCU and CPU. With an interface it is
possible to connect a PC for testing machine operation/functions.

X 301:2 Gnd
X 301:3 Txd
X 301:4 Rxd

X302: Input lock confirmation

An input voltage of 96-276 VAC is required to start the motor.
The function of this input is to stop/not start the motor when the door
lock is open.

Input voltage: 120 V-20 % (=96 V) - 240 V+15 % (=276 V), 50/60 Hz
Current:

Max. 0.01 A

X304: Relay output

The relay is controlled via commands from the PCU (X301). The relay is
not to be activated if communication with the PCU is lost.

Isolation voltage:

3750 V

Voltage:

250 VAC

Current:

max. 2 A

Relay connections: 1-pole, 2-way (three connections)

Connector:

X304:1

Normally open

X304:2

Normally closed

X304:3

Common

X307: Internal

This contact is used for connection of a fan for cooling the MCU.
