ANVER Vacuum Leakage Detector Sounds Alarm when Vacuum Drops

The VLS-08 monitors the vacuum level automatically. If vacuum is lost during a lift,
a loud horn sounds, and a red light flashes to warn the operator. The VLS-08 monitors vacuum level even if the operator is not looking at the lifter, a useful and popular option.

The VLS-08 is a battery powered unit consisting of a pressure sensor, an audible warning horn, red warning light, and test switch, all controlled by a solid state microchip. All ANVER Vacuum Lifters, Vacuum Tilters and Specialty Vacuum Lifting Machinery can be equipped with a VLS-08 Solid State Vacuum Leakage Sensor and Warning System. The system is packaged in a rugged polycarbonate enclosure with a 1/4" push-to-connect fitting for tubing connections.

During each lifting cycle the programmed 'intelligent' processor senses the peak vacuum level. From this point, a 10% loss of vacuum with a leakage rate of less than 1½ in. Hg per second from that peak level will trigger the horn and light, informing the operator of a leak. The alarm will not sound on the detach cycle as with other primitive systems using pre-set switches. Even the smallest leak anywhere in the system will be detected. The VLS-08 system automatically monitors the vacuum level for the operator.

Principle Of Operation

The VLS-08 Vacuum Leakage Sensor is a vacuum level differential detector which is pre-programmed to activate the alarm at a 10% reduction in vacuum (20% reduction with the VLS-08-20 version) with a leakage rate of less than 1.5 inches Hg per second. The alarm will continue until a sufficient increase in vacuum is achieved, indicating no additional leakage is present, or the indicated vacuum level drops below 5 inches Hg.

The horn, LED (red light) and LCD (digital display) can be tested by pressing and holding the "Test Button" for approximately 3 seconds. The unit is also equipped with a low battery indicator which will cause the horn to "chirp" and the LED to flash when battery power is low. The battery should be replaced immediately with a standard 9V lithium battery.

The auxiliary output jack on the VLS-08 is an open collector output which can be connected directly to the VLS-07-AUX-S (auxiliary siren/strobe), or to another 1/0 device, such as an emergency stop function on a CNC control, through a solid state relay. The unit is provided with Mounting Holes for 4 #10 Self-Tapping Screws.

Warning

The VLS-08 is designed to be a warning device for vacuum leakage detection. When properly installed on an ANVER vacuum lifter, the operator will be warned of a slow vacuum leakage and should have adequate time to safely lower the attached load. If the alarm signal is ignored and the lifting operation is continued, the vacuum loss may adversely affect the vacuum "hold", possibly resulting in serious injury to the operator. The VLS-08 is not designed for, nor effective in detecting fast leaks or sudden failures of the vacuum system.

THIS VACUUM LEAKAGE WARNING DEVICE WILL NOT PROVIDE TIMELY WARNING TO THE OPERATOR THAT A REDUCTION IN VACUUM HAS OCCURRED DUE TO INCORRECT USE OF A VACUUM LIFTER, SUCH AS OVERLOADING, LIFTING OVERSIZED LOADS, UNBALANCED LIFTING OR IMPROPER OPERATION OF ANY KIND.

VLS-08-20 Leakage Sensor
The VLS-08 Vacuum Leakage Sensor is also available for Lifters where some vacuum loss is acceptable as long as the vacuum level is within the safe operating range. The VLS-08-20 is set to sound at a 20% loss of vacuum from peak level instead of 10%. These systems are recommended for handling semi-porous to porous loads, on systems using foam vacuum pads, or where the vacuum pump is pre-set to regenerate vacuum after a 15% vacuum loss. If the pump fails to restart or if the leakage is too great, the alarm will sound informing the operator of a possible problem.

ANVER VLS-07-AUX-S Auxiliary Siren/Alarm (VLS-08-AUX coming shortly, looks identical)

The VLS-07-AUX-S is a peripheral device designed to be connected to the VLS-08 vacuum leakage sensor. When the VLS-08 warning is activated, the VLS-07-AUX-S sounds a loud 105db(A) siren and the flashing strobe is initiated. This add-on device is ideal for noisy environments, where the lifter is at a distance from the operator, or where other personnel may be in the general area of use.

This device has a self contained, easily accessible 9V battery and plugs directly into the AUX output port on the side of the VLS-08 Vacuum Leakage Sensor unit with a signal cable 25” [63.5 cm] long (included).
