Wood’s Powr-Grip EO3VLW - Manual (Page 3)

Rev 9.0/9-13 1 EO3VLW: #35193AFT
SPECIFICATIONS
Model Number: EO3VLW
Description:
The Vacuum Loss Warning Buzzer is an optional warning device with an
independent power source. The Warning Buzzer monitors vacuum during lifter
operation and sounds an audible alarm if the lifter fails to reach or maintain the
vacuum level required for lifting. The monitoring system automatically turns on
when the lifter attaches to a load, and automatically turns off when the load is
released.
Power Source: 9 volts DC
Maximum Alarm Volume: 103 dBA at 2 ft [60 cm]
Weight:
1.1 lbs [0.5 kg]
Note: Make sure to add the weight of all options to the lifter weight when you
are selecting appropriate hoisting equipment (see lifter's instruction manual).
Function: Other vacuum indicators should tell the operator whether vacuum is adequate
for lifting. The Warning Buzzer provides additional security by drawing
attention to potentially dangerous conditions, in case the operator fails to
monitor other indicators at the time.
Note: The Warning Buzzer only warns the operator of potentially dangerous
conditions. The Warning Buzzer does not perform any other function and
cannot substitute for care on the part of the operator.
WARNINGS
Powr-Grip is pleased to offer the most reliable vacuum products available.
Despite the high degree of security provided by the Warning Buzzer, certain
precautions must be observed to protect the operator and others.
Never use a Vacuum Loss Warning Buzzer that is damaged, malfunctioning, or missing parts.
Always make sure the Warning Buzzer can be heard while operating the vacuum lifter.
Never lift a load when the Warning Buzzer or any other vacuum indicator signals inadequate
vacuum.
Never disconnect or otherwise disable the Warning Buzzer while operating the lifter.
Always keep other personnel far enough away from the lifter to avoid injury in the event of an
unexpected load release.
Always remember that modifications to the Warning Buzzer may compromise its safety. Wood's
Powr-Grip cannot be responsible for the safety of a Warning Buzzer that has been modified by
the customer. For consultation, contact Wood's Powr-Grip.
