G-194 Safety Sensors / Components
The head is constructed so that it cannot be operated with tools such
as screwdrivers. Always use OMRON’s Operation Key to operate the
head in order to ensure the safety of the machine and protect the
D4BL from damage.
The Operation Key provided for the D4BL is not compatible with that
of the D4BS.
Mount the Operation Key and secure it with one-way screws or
equivalents to prevent easy removal of the D4BL.
Securing the Door
If the Operation Key on the closed door is pulled outside the set zone
by a force caused by vibration, the door’s weight, or the door cushion
rubber, the D4BL may be damaged. Secure the door with hooks so
that it will remain within the set zone.
Tightening Torque
Be sure to tighten each screw of the D4BL properly, otherwise the
D4BL may malfunction.
Switch and Operation Key Mounting
Mount the D4BL and Operation Key with four M5 screws with wash-
ers and tighten each screw to the specified torque.
