2.3.1 Emergency Stop (E Stop)
The machine is fitted with an E Stop which suspends all machine operations. The switch is within
easy reach of the operator and once pressed, the latching switch requires resetting.

cover(s) are secured by electromagnetic locks to prevent the cover from opening when not permit-
ted.

2.3.3 Single Cover Machine
The single cover allows access to the print and tooling area and the paste dispenser, if fitted. The
cover has two electromagnetic locks one on the left edge and one on the right edge of the cover. A
single safety switch (located on the right hand side) monitors the position of the cover.
2.3.4 Dual Cover Machine
The dual cover machine has a front cover which allows access to the print, tooling, and paste dis-
penser areas. The front cover incorporates a sliding cover which allows access to the paste dis-
penser area only.
The paste dispenser cover can be slid open when the paste dispenser is at home position. This al-
lows the paste cartridge or paste jar to be replenished whilst the machine continues printing. During
paste dispensing, the paste dispenser cover is locked. Forcing the cover open during paste dis-
pensing will result in the system power (switched power) being dropped.
As the front cover incorporates the paste dispenser cover lifting the front cover also lifts the paste
dispenser cover.
Behind the paste dispenser cover are two electromagnetic locks. One electromagnet locks the front
cover and the other locks the paste dispenser cover.
