D4BL
DEDICATED RELEASE KEY
The dedicated release key, which is provided with the D4BL, is used
to unlock the protective door in case of emergency or power failure.
To open the protective door, insert the dedicated release key and set
the key lock to UNLOCK.
LOCK
UNLOCK
If the key lock is set to UNLOCK, when the protective door is closed
and people are doing preparation work on the machine inside, the
protective door will not be locked and the machine will not start
operating.
OPERATION KEY
The D4BL is provided with a shock absorptive damper when
shipped attached to the D4BL in order to prevent the D4BL from be-
ing damaged if it is dropped accidentally. Be sure to remove the
shock absorptive damper after the D4BL is mounted.
Do not impose excessive force to the Operation Key in the switch or
drop the Operation Key, or the Operation Key may be deformed or
damaged.
OTHERS
When connecting lead wires with crimp-style terminals to the built-in
switch terminals, do not impose excessive force on the crimp-style
terminals.
Each crimp-style terminal must be connected in the direction as
shown in the following illustrations and the crimp-style terminal must
not be on the case or cover.
Release key
Use the release key to set the key lock to LOCK.
Do not use the release key to start or stop the machine.
This key lock must be normally set to LOCK and sealed with a rub-
ber cap in order to conform to IP67 requirements.
The dedicated release key should be kept only by the person in
charge.
If necessary, to prevent easy access to the dedicated release key,
seal the key lock using a suitable sealing wax. Be careful not to dam-
age the key lock when breaking the seal between the rubber cap
and the key lock.
A cover can be attached to the D4BL. Before attaching the cover,
make sure that the key lock is set to LOCK.
Dropping
Do not operate the Safety-door Lock Switch with a tool other than
OMRON's special Operation Key for the Safety-door Lock Switch,
otherwise the Safety-door Lock Switch may be damaged or the
safety of the system will not be assured.
