GL-V Keyence Light Curtain Installation
The PowerHive uses two different lengths of light curtains. The robot opening receives a tall, 1945mm curtain, whereas the hallway receives shorter 1305mm curtains on each end, connected in series. Prior to May of 2025, all systems utilized the GL-R series light curtains. Starting in August of 2025, the GL-V series light curtains became standard on all systems. The operation of both series is the same, with the GL-V series utilizing some different connectors and mounting brackets. The following sections highlight the difference between the two. There is some assembly involved with the curtains before the final position installation can occur.
GL-V Light Curtain Components Overview
Each light curtain set includes a Transmitter side and Receiver side. They are labeled as such at the bottom of each component as shown below. The Keyence GL-V includes a black M12 pigtail for the receiver side and a gray M12 pigtail for the transmitter side already built into the curtain.
Figure 53: GL-V Light Curtain Component Identification
There are three types of connection cables/components used with the GL-V light curtains:
-
Standard 5-pin M12 male-to-female cables (multiple lengths)
-
Series connection M12 Adapter cables (0.12m)
-
“Y” Connector – Used to simplify wiring back to the LV panel. See Figure 54
Figure 54: GL-V "Y" Connector Wiring
The receivers and transmitters are both connected via standard M12 male-female cables (Figure 55)
The series connection cables are used to connect the entrance and exit hallway curtains together. The two transmitters are connected in series, and the two receivers are connected in series.

Finally, there is a mounting bracket near the top and bottom of each curtain that will be secured as shown Figure 57 in below.

GL-V Light Curtain Electrical Connections
The electrical connections of the light curtains occur at the top and bottom of each component. The bottom connection (built into the GL-V) is the main input to the curtain. The top connection is where the series connection pigtail is installed to add another curtain in series. In the PowerHive, the hallway transmitters are connected in series and the hallway receivers are connected in series.

Figure 59: Main Connection Location
As briefly described in the introduction section, the new GL-V series utilizes a “Y” connector to simplify the wiring from the light curtains back to the LV panel. This “Y” connector will eliminate two wires. The wiring of the “Y” connector is identified directly on the connector as shown in Figure 60 below.

GL-V Light Curtain Securement to Fence Posts - Hall Curtains
The robot and hallway curtain brackets are secured to fence posts using #8 x ¾” self-tapping screws. The robot curtain is mounted at a different height from the ground than the hallway curtains. Each curtain will include a 3D printed template to mark the lower fastener holes on the post. A second template will be provided to locate the upper mounting bracket holes as shown in the figures below. Once mounting brackets are secured to the posts, the light curtains will snap into the brackets and final locating and tightening can be completed. See figures below for template use and reference dimensions in case the template is misplaced.

GL-V Hall Light Curtain Securement to Block/Brick
Wall (If Required)
The same hallway light curtain template can be used for attaching hall light curtains to walls. The fasteners used for this method will be:
-
1” Plastic Sleeve (for #6 screw) - (PN: 103478)
-
#6” x ¾” Screw (PN 103465)
The plastic sleeve should be installed into a 3/16” hole using a 3/16” concrete drill bit.

GL-V Hall Light Curtain Cover on Block/Brick Wall
(If required)
If the hallway light curtains are mounted to block/brick walls, a curtain cover will also be provided to prevent the curtain (2x) from being inadvertently knocked out of alignment on the wall. This cover (PN 102248) mounts using the same plastic sleeve and 3/16” concrete screw used in the section above. The cover should be mounted such that the opening is centered, top-to-bottom and side-to-side with the lense of the light curtain. Note the notch of the cover should be at the bottom.

GL-V Hall Light Curtain Cable Protection on Block/Brick Wall (If required)
If light curtains are mounted on block/brick/concrete walls, a plastic raceway (PN: 102281) is required to be attached along the wall to protect the series connection of the hall curtains as the cable runs along the wall. This raceway comes in 5ft sections and typically one piece will need to be cut to length. The height of the raceway is determined by the mounting location of the yellow curtain covers as shown in Figure 52. The raceway should tuck into the notch of the yellow cover. Each plastic raceway has an adhesive backing. Additionally, each piece
should be attached to the wall using 3 plastic sleeves and concrete screws equally spaced apart.
