TECHNICAL REFERENCE APPENDIX
EMERGENCY MACHINE OFF MODULE
3.2 Appendix to Micron Technical Manuals Chapter Issue 1 Feb 15
WARNING
LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.
ENSURE ALL ELECTRONIC COVERS AND MAIN MACHINE COVERS ARE
FITTED BEFORE OPERATING THIS EQUIPMENT.
Mains input power (115V to 230V) to the machine is routed to the mains isolator
switch at the front of the machine. From the mains isolator it is fed to the M39
emergency machine off enclosure, through one of the cable glands at the rear
panel, to the three terminal blocks TB1 (live), TB2 (neutral) and TB3 (earth).
From the terminal blocks mains power is supplied to the EMO Safe Power
Supply Unit (EMO PSU) and to M37 power supply crate via the closed contacts
of contactors CON1 and CON2.
The EMO PSU supplies +24V dc to terminal block TB4. From TB4 the +24V dc
is distributed to the E-Stop relay RL 1 and the pneumatic dump valve 16SOL37
through the closed contacts of CON1 and CON2.
The front and rear EMO push button switches are connected in series across
relay RL1. If either switch is operated the mains power supply to the M37 power
supply crate is immediately removed. The pneumatic air pressure supply to the
machine is also removed and any remaining pneumatic pressure within the
machine is vented safely to atmosphere.
NOTE
The Gemini platform is made up of two interconnected machines, activation of
any of the front or rear EMO push button switches (two per machine) will result
in the mains power supply and pneumatic air pressure supply being removed
from both machines.
The front panel connector (M39SK5) is provided for maintenance purposes to
apply a +24V dc supply to the EMO enclosure for electrical testing.
NOTE
Following a service visit that involves any disturbance of components in the
mains voltage circuit an electrical test as detailed in the Pre Power section of
the Transportation chapter must be undertaken. Before testing ensure that the
machine is isolated from the factory supply and that any external equipment (ie
upline and downline conveyors) are disconnected.
