EMERGENCY MACHINE OFF (EMO) MODULE
M39 EMERGENCY MACHINE OFF ENCLOSURE
Chapter Issue 2, Nov 14 Technical Reference Manual 5.5
Emergency
Machine Off
The emergency machine off circuit comprises the following:
• The E Stop Relay
•Start Switch
• Front EMO Switch
• Rear EMO Switch
• Pneumatic Dump Valve
• EMO Safe PSU
• Contactors CON1 and CON2
Powering Up When the mains isolator is switched on mains input voltage is supplied to the
M39 enclosure. The input voltage is distributed within the enclosure via Terminal
Blocks TB1, TB2 and TB3. Initially the input voltage is applied to the open
contacts of Contactors CON1 and CON2. The input voltage is also distributed
via fused Terminal Blocks TB6 and TB7 to the EMO Safe PSU. The PSU
produces a +24V dc which is distributed via Terminal Block TB4.
When the Start Button is pressed, the supply to the E-Stop relay is complete
and the relay energises. The relay contacts close supplying 24V dc via Terminal
Block TB5 to the solenoids of CON1 and CON2. The contactors are energised
and the closed contacts complete the circuit to the M37 enclosure allowing the
machine is power up.
An additional set of contactor contacts supply 24V dc to the pneumatic dump
valve allowing the factory pneumatic supply to be applied to the machine.
EMO Operation If either of EMO push button switches are operated the E-Stop relay is de-
energised causing the 24V dc supply to the solenoids of CON1 and CON2 to
be broken. Contacts of CON1 and CON2 are opened, breaking the mains input
voltage to the M37 enclosure, immediately removing electrical power from the
machine. Also the 24V dc supply to the pneumatic dump valve is removed de-
energising the valve. The factory pneumatic supply is removed from the
machine and the any residual machine pneumatic pressure is vented safely to
atmosphere.
