Preparation for Use
ADDvantage-32 PLUS ● AC to DC Power Converter
6-23
6.9 INSTALLATION CHECKOUT
After all equipment is mounted and wired, check over the entire installation to be sure
that all mounting hardware is secure, all pulse generators are properly aligned, and all
wiring interconnections are in accordance with the diagrams in this manual.
NOTE
Insure that ground cables are properly attached to the drive chassis.
Refer to the outline drawing (in drawing package) for location of
grounding points. Note that the 540 amp and above drives have
grounding lugs attached to both the armature bridge chassis and
the field supply chassis.
6.10 POWER UP AND START UP
Applying power and starting up the ADD-32 PLUS should be done only by trained and
qualified personnel. Familiarity with the hardware, the software, and the environment in
which the equipment is to be applied is critical to safe and efficient system operation.
6.11 PULSE GENERATOR INSTALLATION
Proper mechanical and electrical installation of the digital speed feedback device (Pulse
Generator) is critical for optimum performance and reliability. Follow the instructions
provided by the Pulse Generator manufacturer and system interconnection diagrams, if
applicable.
The Microprocessor Board Block Diagram, provided earlier in this section, shows pulse
generator (“Tach”) connection terminals. In addition, for Avtron SMARTach™ pulse
generators (models M285, M485, and M685), the following figure shows how the tach
alarm output should be connected to an ADD-32 PLUS drive.
Particular care should be exercised in selecting the shaft coupling. Use a zero backlash,
Thomas Miniature Flexible or equivalent. When axial endplay exceeds +/-0.020", use
Thomas CCX or equivalent. Do not use a helical spring type or rubber element type
coupling.
