Installation

} Attach the side section using the provided socket head cap screws with the correspond­
ing spring rings on the safety switch. If you wish to prevent the installation from being
manipulated, replace one of the socket head cap screws with the one­way screw
provided (see diagram).
} Fasten the screws with a torque setting of 5.5 Nm +/­0.5 Nm and protect the screws
from working loose with a threadlocker (e.g. Loctite 2700).
} Comply with the maximum lateral offset for the actuator, as stated in the operating
manual for the PSENslock.

WARNING!
Function is overridden due to too short a distance or a foreign body
between safety switch and actuator
Mechanical tolerances or an angular offset can reduce the distance
between safety switch and actuator. As a result, the assured release dis­
tance may not be maintained despite the add­on module and the safety
gate is detected as closed. This can result in serious bodily injury and
death.
The distance between safety switch and actuator must be at least 15 mm
and may not contain any foreign bodies.
After installation, check that the safety switch detects the safety gate as
open and that the "Safety Gate" LED is extinguished when the add­on mod­
ule is activated (see chapter entitled "Operation").
