Included Safety Features
i-Batten with Over-load and Under-load Protection
The i-Batten feature allows the authorized operator to preset sensitivity on the maximum and minimum
loads a specific Vortek hoist will encounter. If the system detects a load outside the set range, indicating
a possible problem, the unit will automatically stop all motion. It is strongly recommended that this feature
be used in order to prevent any injury to personnel or damage to equipment.
Emergency Stop
A red Emergency Stop mushroom head push button is located on each VAC control station. Pushing
the button will disable all motor drives connected through the specific VAC, and 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 VAC touchscreen.
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 40 feet from the Vortek hoist module,
a typical distance for the operator VAC control unit to be located, do not exceed 70 decibels.
