D-145

D4BL

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.
