Safety Sensors / Components
Operation Key
Be sure to use a special Operation Key only.
Do not operate the D4GS-N with anything other than the special
Operation Key. Otherwise, the Switch may be damaged.
As shown below, mount the Operation Key after matching the con-
cave surface of the Operation Key with the convex surface of the
insertion face.
Be sure to adjust the position correctly when mounting the Operation
Key and the Switch to ensure that the Operation Key does not miss
the insertion face and exert an excessive force on the Switch head.
Do not impose excessive force on the Operation Key inserted into
the D4GS-N or drop the D4GS-N with the Operation Key inserted.
Doing so may deform or damage the Operation Key.
Depending on the conditions in which the Switch is used, the rubber
of the Operation Key may deteriorate. If the rubber becomes
deformed or cracked, replace it as soon as possible.
Securing the Door
When the door is closed (with the Operation Key inserted), the door
(or the Operation Key) may be pulled outside the set zone due to the
door’s weight or the door cushion rubber. If a load is applied to the
Operation Key, the door may fail to unlock. Secure the door with
hooks so that it will remain within the set zone.
Wiring
Identifying Wires
Identify wires according to the color (with or without white lines) of
the insulation on the wire.
Wire Colors
Note: “Blue/white, brown/white, or orange/white” means that the cover is blue,
brown, or orange with a white line.
Terminal Numbers
Identify terminal numbers based on the color of the insulation on the
wire.
The safety and auxiliary contacts of D4GS-N models of three-termi-
nal contact construction and those of two-terminal contact construc-
tion are described below.
The auxiliary contacts (orange) can be used as safety contacts.
The safety contacts are direct opening contacts approved by EN and
each of them is indicated with the mark
.
Cut the black core insulator and all unused wires at the end of the
external insulation sheath when wiring the cable.
