Nexen SSE-1200 822729 - Manual (Page 7)

7 FORM NO. L-21089-B-0110
OPERATION
Apply increasing amounts of air pressure to the brake until
the Friction Disc Hub turns freely.
The TSE Brake will remain engaged until sufficient air
pressure is applied to release it. The amount of release air
pressure may vary depending upon the length of the air lines,
amount of springs, and the type of controls used.
AIR CONNECTIONS
NOTE
For quick response, Nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the product. Align the air inlet ports to a down position
to allow condensation to drain out of the air chambers
of the product.
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8573.1:2001
Class 4.4.3 quality.
The following is a common air supply scheme used with
this product. This is an example and not an all-inclusive
list. All air circuits to be used with this product must be
designed following EN983 guidelines.
CAUTION
To avoid unnecessary loading of components,
Nexen recommends not exceeding the air pressure
required to release the brake. The brake seals,
however, have been designed to tolerate up to 7.6
bar (110 PSI) of continuous pressure.
WARNING
Never exceed maximum operating
speeds listed for your product.
(See Table 3).
CAUTION
The temperature limits for this
product line are 4.5-104 Degree
Celsius (40-220 Degree F).
CAUTION
Never exceed life of facing material. Facing
life depends on the volume of material and
the total energy over the life of the unit.
Expected life (in hrs) can be found by:
Time=Volume/(Power*Wear Rate).

WARNING
Ensure proper guarding of the product is
used. Nexen recommends the machine builder
design guarding in compliance with OSHA 29
CFR 1910 “Occupational Safety and Health
Hazards”.
