Sumitomo ASTERO BASA Maintenance Manual

Brake Pack Maintenance Manual
The gear head and motor should be handled, installed and maintained by trained technicians. Carefully read this manual and all
accompanying documents before use.
A copy of this manual should be sent to the actual user of the gear unit.
This manual should be maintained by the user.
1. Safety and other precautions
CAUTION
General
• The gear head and motor should be operated only within its name plate and catalogue ; otherwise, electric
shock, injury or damage to a system may occur.
• Keep hands and all foreign objects from the internal moving part of the gear unit and motor; otherwise,
electric shock, injury, fire or damage to a system may occur.
• Damaged units should be taken off-line; otherwise, injury or fire may occur.
• Do not remove the nameplate.
• Any modifications or alterations of any kind, to the unit, will void the warranty and all subsequent claims.
Transport
• Exercise ample care not to drop the unit and fall during transport.
Installation
• Do not place any inflammables around the gear head and motor; otherwise, fire may result.
• Do not place any objects that will hinder ventilation around motor; otherwise, cooling effect is reduced, and
may lead to a possible fire hazard and a burn due to excessive heat built-up.
• Do not touch the key way at the shaft end or on the inside of the dear unit and motor; otherwise, injury may
result.
• When the unit is used in food processing applications vulnerable to oil contamination, install an oil pan or
other such device to cope with rare oil leaking. Otherwise, oil leakage may damage products.
Coupling with other machines
• Install appropriate guard devices around rotation parts ; otherwise, injury may result.
• Confirm the direction of rotation before coupling the unit with its driven machine. Difference in the direction
of rotation may cause injury or damage to the system.
Wiring
• Do not touch lead wire when measuring the insulation resistance. Electric shock may result.
2.Brake pack characteristics
Sumitomo's brake packs are non contact types that can instantly stop induction motors or reversible motors by electronic braking. The
motor alone can be stopped in less than about 0.1 second. A braking current is applied to the motor for about 0.4 second, then the motor's
input power supply is automatically shut off. Unlike electromagnetic brakes, brake packs don't store torque. Since they have no parts
to generate mechanical friction, they have long lives. To control a motor using brake packs, a DC power supply for the signal is required
(12~24VDC, 0.1A or larger).

DANGER
Wiring
• Connect a power cable to the motor according to the connection diagram or maintenance
manual; otherwise, electric shock or fire may result.(Without terminal box, exercise insulation in
the connecting part.)
• Do not forcibly curve, pull or clamp the power cable and lead wires; otherwise, electric shock may
result.
• Correctly ground the grounding bolt; otherwise, electric shock may result.
• Use power source stated in the nameplate; otherwise, motor's burning or fire may result.
Operation
• Never approach or touch any rotating parts (shaft, etc.) during operation; otherwise, loose
clothing caught in these rotation parts may result in severe injury.
• When the power supply is interrupted, be sure to turn off the power switch. Unexpected
resumption of power may cause injury or damage to the equipment.
Daily inspection and maintenance
• Never approach or touch any rotating parts (shaft, etc.) during maintenance ; otherwise, loose
clothing caught in these rotating parts may result in severe injury.
Inspection upon delivery
• Verify that the unit received is in fact the one ordered. When a different product is installed, injury
or damage to the system may result.
