Front Corner
Panels
To remove the front corner panels, carry out the following:
1. Raise the front printhead cover.
2. Remove the front panel.
3. Gain access to the rear of the EMO switch.
4. To disconnect the EMO carry out the following:
a. Locate the yellow locking collar at the rear of the switch.
b. Slide the collar rearwards towards the switch contact assembly against
spring pressure.
c. Viewed from the rear of the switch, rotate the locking collar anticlockwise
to release the contact assembly from the switch body.
5. Remove the front corner panel.

Pneumatic Supply The machine requires a pneumatic supply of clean, non lubricated air which
should maintain a minimum pressure of 5 Bar and a maximum of 7 Bar.
The air should be to ISO 8573.1 standard, quality class 2.3.3, where:
• 2 dirt = 1 micron
• 3 water = -20°C pressure dewpoint
• 3 oil = 1mg/m3
If an emergency stop is initiated via an EMO push button switch, the pneumatic
supply is closed off and any pressurised air remaining within the machine’s
system is vented via the pneumatic dump valve.
Electrical Supply The factory mains supply for the machine is routed through the front panel
mounted mains isolator switch to the M39 EMO enclosure. If both EMO push
button switches are de-activated and the Start button has been pressed mains
voltage is applied to the M37 power supply enclosure. From the enclosure
various low voltages are distributed throughout the machine.
Figure 2-3 Mains Electrical Supply
The machine operates on 115V or 230V± 10% 50/60Hz single phase ac mains,
current rating 10A or 2.4Kw.
NOTE
The voltage selector of the VF35i vacuum filtration unit needs to be set to the
factory mains supply. This is carried out in the Machine Preparation Chapter of
the Micron Installation Manual.
ASM recommends a power supply capacity of 2.4KVA or greater.

ASM requires additional machine supply protection with the fitment of an
external double pole circuit breaker conforming to national, federal or local
legislation. ASM recommends that the external circuit breaker is fitted near the
DEK printer and within easy reach of the operator. Use the following table to
ensure the recommended circuit breaker is used:
NOTE
An over current circuit breaker protects both the machine’s internal wiring and
components from overheating or catching fire during fault conditions. Under no
circumstances must a circuit breaker of value greater than 25 Amps be fitted.
Equipment If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
This equipment should be used in accordance with the operating instructions.
ASM absolves itself of all responsibility if the machine is not used within its
operating envelope or for it’s intended purpose.
