7 FORM NO. L-21222-E-1211
OPTIONAL LOCKING MODE SENSOR
AIR CONNECTIONS
1. The Nexen rod lock is equipped with a NPTF or BSPP
port for the air inlet. Route clean air, using soft or hard
lines, supplying at least 4.1 bar [60 psi] to facilitate full
disengagement.
NOTE: Install the valve in close proximity to the Rod
Lock unit for faster engagement and disengagement.
Higher air pressures will also speed the disengagement
time, but do not exceed 8.0 bar [120 psi] air pressure.
2. The Nexen rod lock is equipped with a port for the
internal vent (filters are included with most models).
If the air quality around the application is poor, route
the vent of the rod lock to a more suitable area, or
use a filtered breather. Contact Nexen for available
components.
NOTE: Clean air is important for proper Rod Lock
functioning. Debris inside the Rod Lock may inhibit
performance and/or shorten the life of the product.
DANGER
Support the load before disengaging
the Rod Lock. Failure to support the
load could result in serious bodily
injury.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8573.1:2001
Class 4.4.3 quality.
NOTE
For quick response, Nexen recommends a quick
exhaust valve and short air lines between the
Control Valves and the unit. Align the air inlet ports
to a down position to allow condensation to drain
out of the air chambers of the product.

Nexen “RLSSB” products are equipped with a T-slot
for an optional locking mode sensor (See Table 2). This
sensor can be positioned in the T-slot to relay when
the Rod Lock is disengaged or engaged on the shaft.
Once the sensor is properly located to relay when the
Rod Lock is in the desired state, use a standard flat-head
screwdriver or 1.5 mm allen wrench to turn the screw
and fix the sensor in the T-slot (See Figure 2).
