Operation Key
•
Use only the designated Operation Key. The Head has been
designed so that operation is not possible with a screwdriver or
other tools. Using anything other than the designated Operation
Key may damage the Switch or affect machine safety.
•
Do not operate the Switch with anything other than the special
OMRON Operation Key, otherwise the Switch may break or the
safety of the system may not be maintained.
•
Do not impose excessive force on the Operation Key while the Key
is inserted into the Switch or drop the Switch with the Operation
Key inserted. Doing either of these may deform the Key or break
the Switch.
Switch Contacts
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The contact
surfaces will become rough once they have been used and contact
reliability for smaller loads may be reduced.
Release Key
•
The release key is used to unlock the Switch in
case of emergency or if the power supply to the
Switch stops.
•
If the release key setting is changed from LOCK
to UNLOCK using the enclosed release key, the
lock will be released and the safety door can be
opened (mechanical lock models only).
•
After setting the release key to UNLOCK to, for example, change
the head direction or perform maintenance, be sure to return it to
the LOCK setting before resuming operation.
•
The release key is set in the unlock position at the factory for the

•
If the release key is set to UNLOCK when the Switch is used for the
door of a machine room to ensure the safety of people performing
adjustment work inside, the door will not be locked when the door
is closed and no power will be supplied to the equipment.
•
Do not use the release key to start or stop machines.
•
The auxiliary lock must be released using the release key only by
authorized personnel.
•
Do not impose a force exceeding 1 N·m on the release key screws.
The release key may be damaged and may not operate properly.
•
To prevent the release key from being used by unauthorized
personnel, set it to LOCK and seal it with sealing wax.
Rear Release Button
•
The rear release button is used for
emergency escapes when someone locks a
worker in the work area (hazardous area).
•
The door can be unlocked by pressing the
rear release button.
•
After the rear release button is used to
unlock the door, pull the button out to restore it to its original state.
If the button is left pressed in, the door will not lock when the door
is closed and power will not be supplied to the equipment.
•
Mount the Switch so that the rear release button can be operated
by a worker inside the work area (hazardous area).
•
For the D4JL-

-01-SJ, attach the enclosed rear release
button with the rear release button attachment screw.
When you attach the rear release button, use a wrench to hold it in
the specified position and tighten the screw to the applicable torque.
Trapped Key
•
The trapped key is released when
power is supplied to the solenoid.
Turn the trapped key to the
UNLOCK position and remove the
key to unlock the door.
The door cannot be unlocked solely
by supplying power to the solenoid.
As long as a worker has the trapped key with him when he enters
the work area (hazardous area), he cannot be locked inside by
another worker.
•
Do not impose a force exceeding 1 N·m when operating the key.
Otherwise, the Switch may be damaged and may not operate properly.
Attaching a Cover
•
Make sure the release key is set to the LOCK position before
covering the D4JL.
•
When attaching a cover, be sure that the seal rubber is in place and
that there is no foreign material present. If the cover is attached
with the seal rubber out of place or if foreign material is stuck to the
rubber, a proper seal will not be obtained.
•
Do not use any screws to connect the cover other than the
specified ones. The seal characteristics may be reduced.
•
Use one of the following methods when covering a Trapped Key Switch.
When the Operation Key is removed (door open):
Cover with the trapped key removed (UNLOCK).
When the Operation Key is inserted (door closed):
Cover with the trapped key inserted (LOCK).
