Nexen SE 625 883000 - Manual (Page 7)

7 FORM NO. L-20078-C-0210
NOTE
Nexen’s DAP clutch begins to deliver torque at
approximately 50 psi. Below 50 psi the spring force of
the brake overcomes the air cylinder thrust, therefore it
is important to have pressure regulated air to the control
valve.
WARNING
Never exceed maximum operating
speeds listed for your product.
(See Table 2).

CAUTION
The temperature limits for this
product line are 4.5-104 Degree
Celsius (40-220 Degree F).
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”.
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).
Nexen’s DAP Spring Engaged Brake remains engaged
until air pressure is applied to activate the clutch. The
brake releases at approximately 40 psi. The brake may
also be released manually by alternately turning Set
Screws (Item 24) clockwise until the Output Shaft (Item
1) rotates freely. To re-activate the brake, turn Set Screws
(Item 24) counter clockwise until they are flush with the
outside diameter of the Output Housing (Item 2).
Periodically check air line connections and mounting bolts
to make sure that they are tightened securely.
