01 SAFETY INFORMATION

Warnings, Cautions, and Notes

All Warning notes contained in this manual indicate information that may endanger personnel.

WARNING

The Daktronics rigging system is designed to raise and lower equipment under the rated hoist capacity ONLY.

Only trained and authorized personnel should be permitted to operate the Daktronics system. The unauthorized use,
alteration, or use for purposes other than those for which it was designed may cause injury to persons, damage to
the equipment, or create conditions which could lead to fatalities. All proper safety considerations must be observed.
While operating the Daktronics rigging system, a spotter must be used in conjunction with the user at all times. The
spotter must have a clear view of all moving elements while maintaining contact with the user. If an unsafe situation occurs, the
spotter must immediately signal the user to halt all movements until the environment is cleared of any person or obstruction.

All installation and maintenance involving the Daktronics drive unit itself or the main electrical control cabinets
will require trained personnel. Simple daily maintenance activities of the workstation may be carried out by the
operators, and in most cases will be all that is needed once installed.

Electrical Safety—General Warning

WARNING

Before working on any of the Daktronics hoists, the main electrical disconnect must be
turned off and locked out according to U.S.A. OSHA regulations 29 CFR 1910.147 or
Australian regulations AS 1418.1 Section 8.10.3.4.

The voltages used in the motor drive and master control panels can cause severe electrical
shock and/or burns. Extreme care is necessary at all times when working with the motor
drives. Only authorized personnel should carry out any installation, commissioning, or
maintenance of the electrical systems. All drive systems have been tuned at the factory
and will not require any additional alteration or adjustment by the owner’s personnel
unless specifically authorized by a Daktronics representative.

02 GENERAL INFORMATION

WARNING

The Daktronics hoist system is an automated rigging system, meaning that the load is not counter-weighted. Each
hoist can lift loads only up to the design capacity. Overloading will result in electrical overload protection shut
down of the hoist and possible damage to rigging components.

WARNING

The Daktronics Banner Hoists are not designed to raise and lower people.
These hoists should NEVER be used for this purpose.

The DBH-150 unit must only be used with a maximum load equal to the capacity stated for the
model below. Overloading the system may result in serious injury or an inoperable system

If it is necessary to operate a hoist from a location where the operator's view of the moving
load is obstructed, a second person must be used to observe the load and communicate to
the operator.

DBH-150 Unit Overview

The Daktronics Banner Hoist is a chain-driven self-contained hoist platform that can be powered using single phase
120V 60Hz or 240V 50Hz electricity. The electricity powers the chain motor which rotates the drums, as well as the
power supply that in turn powers the RF receiver built into the hoist with 24 V DC power. It also controls the operation
of the chain motor and brakes.

The load is raised and lowered by the two available lift lines, utilizing “Zero-Fleet Angle” design architecture to ensure
that the cabling does not wind up on top of itself, protecting the cable and drum from wear.

Control over the unit is performed by utilizing the hand-held RF remote within line of sight of the hoist. It allows the
user to power on/off the unit, raise/lower the lift lines, and remotely program the RF remote to correspond to multiple
receivers, allowing one to control multiple banner hoists at once with one remote simultaneously. The RF remote
requres 2 AA alkaline batteries in order to operate.

03 GENERAL OPERATION/CONFIGURATION

BANNER HOIST REMOTE

The Banner Hoist System operates using a wireless remote
control that communicates with the hoist using radio wave
RF transmission. When operating the Banner Hoist system,
always have a clear line of sight to the hoist to minimize RF
interference and to promote safe operational use.

Powering On/Off

To power up the Banner Hoist, simply press the green
START button (Figure 1). To power it down, press the
red STOP button.

Raising/Lowering

To raise the Banner Hoist, simply press the UP button
and press the DOWN button.

Battery Maintenance

To replace the two AA alkaline batteries remove the
screw on the plastic back plate using a flat-head screw

GENERAL OPERATION/CONFIGURATION

5

RF Tuning/Maintenance

There are two ways to tune the remote and the hoist
assembly so that they synchronize. The first method is
through reprogramming the remote using the remote
interface plug (Figure 3) in conjunction with the
Copy Module #700PROC pendant (Figure 4) next
to the batteries. The second and less time consuming
method is through using the remote itself next to the
antenna receiver to program the receiver to respond
to the remote’s transmitting signal.

A. To program the receiver to respond to a

specific remote, first ensure the remote and
receiver are of the same model, and
operate on the same frequency band by
opening up the remote and receiver and
ensuring their frequency crystals match.

B. Place the remote as close as possible to the
receiver to avoid unnecessary interference.

C. Turn off the receiver’s power supply, then turn

it back on. Because the receiver is fed power
through the hoist itself, turn the hoist
assembly on and off.

D. Within 4 minutes of turning the Daktronics

Banner Hoist back on, press and hold the
STOP button. Continue holding and then press
and hold the DOWN button. While holding
the previous two buttons press the UP button
4 times, and release all the buttons when the
red LED light on the remote flashes. If done
correctly the remote and receiver on the hoist
should be synchronized.

E. It is possible to program multiple hoist receivers

to respond to one remote I.D. through this
programming method.

F. If the remote programming data has become

corrupt or access to the hoist receiver for
optimal remote synchronization is restricted, use
of the Copy Module #700PROC can allows
copying the programming data of one remote
into another remote, allowing that remote to
work with the equipment the source remote
is programmed to work with. (Copy Module
#700PROC sold optionally.)

G. If problems continue with the remote and/or the

receiver on the hoist, consult with Daktronics,
see manufacturing contact on the inside cover
of this manual.

ADJUST & INSPECT BANNER HOIST

After installation under normal circumstances, users
should never have to physically move the hoist assembly
or open it up for maintenance. It may become necessary
though to open up the side casing and check the cables
on the drum should they begin to run over themselves.
If the upper and lower limits of travel need changing,
it is necessary to open the smaller side panel near the
receiver antenna to gain access to the rotary limit switch.

DBH-150 Limit Switch Operation & Adjustment

The limit switch assembly is comprised of a fully enclosed
4-switch rotary mechanism attached to the hoist drum
shaft with a flexible coupling. As the drum shaft turns,
the switch mechanism rotates cams in one direction or
the other to actuate snap action switches by depressing
roller levers attached to each switch.

The upper and lower limits, both normal and over-travel,
are set from the factory for the maximum travel of the
hoist. After installation, it may be necessary to reset
these limits based on the height of the installation and
the desired travel distance. The limit switch assembly is
shown in Figure 5 and is located under the left most
front panel of the hoist where the wireless receiver
antenna protrudes. Remove this panel to gain access to
the limit switch assembly. It will be necessary to remove
the yellow plastic cover to make the switch adjustments.

As shown on Figure 6, the Rotary Limit Switch is
comprised of a Lower Over-travel Limit Switch, a Lower
Normal Limit Switch, an Upper Normal Limit Switch,
and an Upper Over-travel Limit Switch. The limit switches
are activated when the white cam wheel rotates into the
roller lever on the limit switch.

Initial Lower Limit Adjustment

To initially adjust the lower limits, start by lowering the hoist
to the desired low limit height. Adjust the lower normal cam
wheel by turning the yellow set screw associated with the lower
normal limit switch (Figure 7) counterclockwise until it contacts
the back side of the roller lever on the switch, and actuates the
switch. Operate the hoist up and down into the limit to test.
Re-adjust the switch as necessary by rotating the yellow set screw
counterclockwise to raise the limit or clockwise to lower the limit.
Turning the adjustment screw ¼ turn will change the limit by

approximately9"(230mm).

Continue by setting the lower over-travel limit. Operate the hoist
until it actuates the lower normal limit and stops. Adjust the
lower over-travel cam wheel by rotating the yellow set screw
counterclockwise until it actuates the lower over-travel switch.
With the hoist power on and the hoist enabled from the remote
control, the main contactor (LC1) will de-energize. Once the
switch is actuated turn the yellow set screw ¼ turn clockwise.
The switch will deactivate and the main contactor will energize.

Thiswillgiveapproximately6"(150mm)ofover-traveldistance

Initial Upper Limit Adjustment

To initially adjust the upper limits, start by raising the hoist to the
desired high limit height. Adjust the upper normal cam wheel by
turning the yellow set screw associated with the upper normal
limit switch (Figure 7) clockwise until it contacts the front side of
the roller lever on the switch, and actuates the switch. Operate
the hoist up and down into the limit to test. Re-adjust the switch
as necessary by rotating the yellow set screw counterclockwise
to raise the limit or clockwise to lower the limit. Turning the
adjustment screw ¼ turn will change the limit by approximately
9"(230mm).Figure 8 illustrates the labels corresponding to
each screw.

Continue by setting the upper over-travel limit. Operate the hoist
until it actuates the upper normal limit and stops. Adjust the
upper over-travel cam wheel by rotating the yellow set screw
clockwise until it actuates the lower over-travel switch. With the
hoist power on and the hoist enabled from the remote control,
the main contactor (LC1) will de-energize. Once the switch is
actuated, turn the yellow set screw ¼ turn counterclockwise. The
switch should deactivate and the main contactor will energize.

Thiswillgiveapproximately6"(150mm)ofover-traveldistance

beyond the normal upper limit.

Once the limit switches are set, under normal operating
conditions they should not have to be reset. If the hoist is moved,
or the high or low limits do need to be reset for any reason, do
so by using the procedures above. When readjusting the limits,
make certain to reset the over-travel limits as well.

MECHANICAL INSPECTION

Inspection Schedule

Mechanical and electrical inspections shall be completed
in accordance with local regulations or every 5 years,
whichever comes sooner. Inspections shall be completed
by a competent person who is certified for field service.
All repairs shall also be inspected nd approved by a
competent person who is certified for field service prior
to the hoist being returned to service.

After usage over long periods of time, certain parts of
the Banner Hoist Assembly may become more audible
as certain components require periodical lubrication.
Examples of these parts of the assembly that could
end up requiring such inspection and maintenance
are shown on the illustrations to the left. Take into
consideration the environment of where the Banner Hoist
assembly will be installed to reduce the likelihood of
wear. On chain drives and acme parts, white lithium
grease should be used to lubricate (refer to
Figures 10-12).

Always ensure that when operating and performing
maintenance/inspection on the Banner Hoist system
that there is at least enough weight on the cables to
keep them taut. If the cables are allowed to become
slackened, the cable may become unwound from
the drum or for the cable to cross-over itself. Both
of these conditions present a safety hazard and will
depreciate the life of both the cable and the drum.

If a situation occurs where the cable has run over
the drum, simply lower the hoist to its lower limit and
pull the cabling outward, ensuring that the cabling
left on the drum is in line. Then with weight applied
raise the hoist to correctly rewind the cabling. Also
ensure that the cable is being correctly guided
through the Plastic Feed Guide (Figures 13,14)
while performing the rewinding. It may be necessary
to remove the front panel of the hoist to ensure
the cable is wound correctly on the drum. Should
additional problems or questions occur, do not
hesitate to call Daktronics for additional support.

Positioning of Drum Cable Keepers

Verify that the drum cable keepers are positioned
correctly as shown in Figure 15. The assemblies should
run parallel with the drum and contact the cables to
keep them in the drum grooves. If the plastic keeper part
is out of position, it should be relocated as shown. The
plastic keeper part is spring applied and should be free
to come off the drum. Lift the ends off the drum to ensure
the springs and resulting assembly are not binding.

Figure 15: Drum Cable keepers

MAINTENANCE/INSPECTION

ELECTRICAL INSPECTION

Under normal conditions, the Daktronics Banner Hoist should
provide years of maintenance free service. Daktronics recommends
periodic electrical inspections for corrosion and wear, particularly
in high temperature and/or high humidity environments. Should
issues occur or if the hoist is exposed to water or other fluids,
immediately disconnect incoming power and contact Daktronics for
technical assistance.

Figure 16 shows the proper wiring for the Banner Hoist power
panel. If electrical issues are observed, this is where technical
assistance will focus.

Figure 17 displays the Banner Hoist RF Receiver and the
schematic of the wiring in the power panel in Figure 16 which
will be used as a reference when receiving technical assistance.

VISUAL INSPECTION

A quick visual inspection can provide valuable information about
how the hoist is operating and whether further maintenance is
required. Periodical visual inspections should be completed in
between scheduled maintenance inspections.

When visually inspecting the hoist, look for components that
have become loose or possible failures such as cracking in the
metal framework or other components. In addition, check for the
following:

· Cables should be tight around the drum, in the correct grooves
and not overlapping

· Cables should follow the correct path from the drum through the
cable guide assembly

· Chains are fitted properly around the sprockets

· Adequate lubrication on the chains and acme screw parts

· Intact wire terminations

· No frayed wires

· No visible corrosion or wear on or around the electrical
components
