Daktronics E SERIES - Manual (Page 5)

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.
