01 SAFETY INFORMATION

Warnings, Cautions, and Notes

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

WARNING

Before working on any of the Vortek hoists, the main electrical disconnect must be
turned off and locked out according to OSHA regulations 29 CFR 1910.147.

The Daktronics rigging system is designed to raise and lower theatrical equipment under the rated hoist capacity
ONLY. This system is NOT designed to lift or lower personnel, and should never be used for that purpose.

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 Vortek drive unit itself or the main electrical control cabinets will
require trained personnel. Simple daily maintenance activities such as cleaning of the touchscreen and the
E Series controller 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

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.

SAFETY INFORMATION

Included Safety Features

Over-load and Under-load Protection - Load Sensing

The E-Series Enhanced Control system allows the authorized operator to preset maximum and minimum load
thresholds for each individual Vortek hoist. If the system detects a load outside the set range, indicative of a
possible problem, the unit will automatically stop all motion. If no range is set by the operator, the hoist will
stop based off the maximum rated load and minimum under-load values pre-programmed into the system.
Administrators are recommended to use this feature to prevent any possible injury to personnel or damage
to equipment..

Emergency Stop

A red Emergency Stop mushroom head push button is located next to the HMI touch-screen interface.
Pressing this button will disable all motor drives connected through the respective HMI’s MODBUS system, as
well as set all motor brakes. This will stop all motion of the attached loads on each Vortek hoist immediately,
and inhibit further movement until reset.

The Emergency Stops should ONLY be used for real emergencies, or when required to reset a motor fault if
indicated on the E-Series Alarms screen on the HMI.

Vortek Back-Up Brake

This secondary mechanical braking system is designed to hold the rated load in the improbable case of
a failure of the primary motor brake or gearbox. This system acts independently of any electrical inputs on
the system.

Compliance with Regulations

The Daktronics system complies with the relevant European directives required for the CE mark,
including:

98/37/EC: Machinery Directive
73/23/EEC: Low Voltage Directive
89/336/EEC: Electromagnetic Compatibility

Independent reviews/tests in support of above compliance

EN55022 Class A Radiated and Conducted Emissions
EN61000-4-2 Electrostatic Discharge
EN61000-4-6 Conducted Susceptibility
EN60950, 60204 Safety Review

Airborne noise emissions

Continuous A-weighted sound pressure levels at distances 440 feet from the Vortek hoist module, a
typical distance for the operator E-Series HMI unit to be located, do not exceed 70 decibels.

WARNING

02 GENERAL INFORMATION

The Vortek batten hoists are not designed to raise and lower people.
These hoists should NEVER be used for this purpose.

The Vortek
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.

Each hoist system consists of an integral electric motor driven gear reducer, directly coupled to a cable drum,
which winds steel cables (wire ropes) leading over sheaves installed within the hoist assembly and along the
structural steel of the building.

The Vortek hoist system consists of three basic parts:

Motor Electronic Variable Frequency Drive (VFD)

The Electronic Variable Frequency Drive and dynamic braking resistor for each motor are located in each Vortek
motorized hoist. A local control panel is located on each hoist for programming and diagnostics by factory
personnel. There is a reset-able circuit breaker located at each power point on the High Voltage Wireway
(HV-WW). The rated twist-locking plug on each unit acts as the main high voltage disconnect along with its
corresponding circuit breaker (CB).

Hoist Assembly (Cable Drum, Load Brake, Limit Switches, and Frame)

The Vortek hoist assemblies are mounted on the rigging steel at the top of the stage house. The gear motor,
helically grooved cable drum, support bearing and frame structure are all factory assembled and tested. Maximum
upper height and minimum lower height are set by limit switches which are adjusted by factory-trained personnel
during installation and commissioning of the system. A position encoder is located at the brake end of each hoist
drum, attached directly to the drum shaft. Each hoist assembly is also equipped with a LOAD BRAKE, a unique
safety feature provided exclusively by Daktronics. This unit is designed to engage automatically when the load is
being lowered. This greatly reduces any possibility of a load to descend uncontrolled.

03 THEORY OF OPERATION

Each Vortek® hoist is connected to the main high voltage power buss through a safety twist-locking plug. This plug
brings in the main 3-phase power that is connected to the motor drive and motor brake located in each hoist
assembly. Also connected to each hoist assembly through safety locking connectors are 24 V DC power, E-Stop
circuit and a computer network cable.

The motor drive controls all movements of the hoist. Each drive on each hoist contains programming to identify it
to the network. This programming also includes but is not limited to maximum speed, acceleration and gear ratios.
Each motor drive monitors an incremental encoder and emergency stop status. The incremental encoder is used for
position control. The emergency stop status is used to detect the operation of the emergency stop system.

Monitoring of each hoist is done over the network using the master program running in the Human Machine
Interface (HMI). The HMI is typically located at stage level inside the master control cabinet. Inside the master
control cabinet is the HMI and the I/O module. A 24 V DC power supply that powers the I/O module and the
E-stop circuit is also located in the master control cabinet.

The HMI is a touch screen based PLC control system developed by Emerson’s Control Techniques. The PLC program
running inside the HMI allows the operator to operate any hoist connected to the system. The HMI is connected
directly to each hoist motor drive through a series of adapters forming a MODBUS driven token ring topology
network, as well as connected to the I/O module to allow the use of a remote pendant and manage the e-stop
circuit. During operation of the HMI, data is transmitted through the MODBUS network from the HMI to the selected
hoist motor drive. Likewise, data is received back through the MODBUS network to the HMI to relay encoder
information and load sensing information. The 24 V DC E-stop circuit is also connected to the E-stop button located
next to the HMI on the front of the master control cabinet.

Communication with the hoists is also possible using Ethernet protocol; however, in order for this type of
communication to be possible, the hoists must have an Ethernet module installed and the HMI configured and
wired properly to run the protocol. Ethernet switches are also necessary when using this type of communication
and would be installed in the low voltage wireways.
