Inspect shipment carefully for any damage immediately. If freight damage occurs, contact the
freight carrier immediately. Do not discard crating materials until installation is complete.
Make sure that all parts are shipped with the unit. A gatefold attachment includes:
1) Gatefold plate
1) Optical sheet sensor with cord
1) Encoder cable
1) Main control box
• Note that an air compressor is not supplied with the unit. It is recommended to use an air
supply with (90) PSI or (5) bar air pressure.
• Note that the airline fitting to connect to the customer air supply is not included due to the
variety of possibilities. Be sure to measure and procure the correct connection. Note that a
water trap is recommended to eliminate condensation from the air system.
• Note that the pneumatic gatefold does not require a stationary deflector above in the #2
foldplate position. Previous electronic gatefold designs required a stationary deflector for
mounting in the foldplate position above the gatefold plate when installed in the folder.
• The incoming electrical power for the gatefold control box is supplied using the X10
connector on the left-hand side of the main operator’s control box of the Baum folder. Later
models include this plug as standard equipment on the main box. Some early model Baum 20
series folders do not have this connection pre-wired. If your Baum 2018 or 2020 folder does
not have the X10 connector, contact the Baum parts department for the correct plugs and the
Baumfolder technical support department for wiring information for your folder.
• Note that these instructions are for the initial installation. The instructions for installation for
each use afterward are found in the operator’s manual. You must follow the set procedure for
installation for operation for successful results.
• The control box of the gatefold attachment can also be used for specified gluing operations
with addition of the proper gluing heads and modifications to the folder. Both inline and inplate gluing applications are adaptable. For more information on folding and gluing, refer or
request a copy of the Baum “Gluer Guide”. Baum offers complete segmented fold rollers and
grooved foldplates to meet these needs. Using genuine Baum parts is required to maintain the
factory parts warranty on new Baum installations. Use of other manufacturer’s parts will void
the factory warranty.
• The timed perforations function on the control is not applicable to the Baum 20 series
folders. This feature requires pre-slittershafts on the folder that are not available on the Baum
20 Series.
• Wiring information shown is applicable to Baum 20 series with DCT500 electrical design.
To connect to Baum 20 series folders previous to this design, contact the Baum technical
support department at 1-800-543-6107.

1. Install mounting post to feeder
frame on the non-operator side of
the folder. Drill (2) ¼ inch or 6.5mm
diameter clearance holes in the
frame as shown. Use the hardware
kit supplied to mount the post to the
frame.
2. Place the control unit on top of
the mounting post. Install the power
cord. Connect the Optical sheet sensor
to Input 1. Connect the electrical cord
from the gatefold plate to Output 1.
Connect the encoder cable to the
Encoder connection. View shown is
from the backside.
3. Disconnect power from folder.
Wire the other end of the Encoder
cable to the main electrical box on the
folder. Insert encoder cable through
an opening available in the back of
the main control box of the folder.
Go to connector block 2X15. Connect
the gatefold encoder cable wire #1 to
pin #1 with the white wire.
Connect gatefold encoder cable wire
#2 to pin #2 with green #2 wire.

4. Remove wire #13L1 from the side of Auxiliary
contact block K2. Move this wire up to the open side
of terminal 12L1 on the terminal strip TB-1.
5. Connect the blue air line hose to the air regulator at one end and to the gatefold plate at the
other end. The connections are brass quick connect couplings. It is best to do this without air
pressure in the line.
6. Connect the airline from the air
regulator to the incoming air supply.
Note that (90) PSI or (5) bar is
required for the correct operation.
