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 via the mains isolator
switch and the M39 EMO enclosure. From the M39 enclosure it is fed to the M37
power supply crate, through the cable gland 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 following:
• M37SK31 PC Supply
• M37SK32 Monitor Supply
• M37SK33 Spare
• M37SK34 Spare
• M37SK35 Internal Vac Pump via Mains Filter and CB34
• PSU
PSU is a Switched Mode Power Supply Unit (SMPSU) which converts the ac
into the following dc supplies:
•+24V US
• +24V SW
•+5.5V
•+12V
•-12V
•+42V
The dc supplies from the PSU is fed to the power distribution PCB. Mounted
on the power distribution PCB is the PSU monitor board which enables moni-
toring of the power supplies.
A printhead cover loop consisting front cover interlock, interlock blanking plug
and E Stop relay are fitted to ensure motor power is removed if the front
printhead cover is opened.
A two handed safety relay, left jog button and right jog button are fitted to enable
certain functions to be performed with the front printhead cover open.
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.
