NOTE
use the length of air line supplied to make the connections
between Calipers.
The Elbows and Tees are push-lock fittings. To install the air line,
simply push the air line into the fitting until it stops. To disconnect,
push in on the fitting collar and pull the air line out.
There are a variety of plumbing options with the multi-caliper
XTB Brake. Figures 11 through 14 show typical air line
connections.
NOTE
Not all the fittings are used for making Caliper connections.
Save the extra fittings for use as replacement parts.
The Four Stage Caliper Manifold (Product No. 835134) directs
air pressure to three separate sets of calipers connected as a
single pair or series, providing three torque ranges with just one
brake for handling a variety of web materials. It consists of a
3-Way, ON/OFF Toggle switch and three other Toggle switches
allowing the user to select caliper operating stages and vary
torque output (See Figures 11-14).
Any number of calipers may be used in each stage. Actuating
one switch, two switches, or all three switches will vary the torque
output to meet a predetermined braking requirement.

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.
