The AVS30 micro is an Automatic Voltage Switcher rated at 30 Amps. The AVS will switch off the

equipment connected to it if the mains power goes outside pre-set acceptable limits, and will reconnect automatically when the mains power returns to normal. Reconnection takes place after adelay, to ensure stability of the mains.the new version of the AVS has a built-in microprocessor that adds advanced features. These include:

Five LEDs accurately display the status of the AVS in the following symmetrical traffic light design:

Red

High Incoming Voltage

OFF

Yellow

AVS is in what state after a High voltage transition

OFF

Green

Mains Normal

ON

Yellow

AVS is in what state after a Low voltage transition

OFF

Red

Low Incoming Voltage

OFF

By adding microprocessor control to the AVS30, you can enjoy advanced functions which include;* Variable time delay* Variable Low voltage disconnect level* Variable H igh voltage disconnect level* Variable Blind time. R esponse time to under voltage disconnect.All these new features can be set at installation time.* The AVS30 M icro has a reset button on the front panel. This button will eliminate the delay time.* 5 LEDs to indicate the state of the mains supply.

OPERATION1. Make sure that your load does not exceed the rating of the AVS which is 30Amps.2. The limits of the AVS as a standard are set for a window of 190-260 volts.3. The AVS has to be wired to the mains supply and to the equipment it is supplying.Please refer to the wiring diagram on page 9.4. On first switching on, there will be no output for the wait time of approximately three minuteswhile the AVS monitors the mains.a) To by-pass the wait time, press the re-set button on the front panel of the AVS30.b) I f a different wait time is required, then change the settings on potentiometer markedWAIT. Settings are available in increments up to 10 minutes.You can also set the W AIT dial to M AN. W hile on M AN the AVS30 will not reconnect the mainsunless the R eset button is pressed. For that period the yellow LED indicates that the mains arewithin acceptable limits, after which the green LED goes on and the load is connected.5. A different blind time can be set if a different undervoltage disconnect limit is required.Under voltage blind time means the AVS ignores any undervoltage conditions during this time.The AVS will not switch off unless the under voltage last longer than the blind time.6. It is recommended that the AVS is kept switched on, and the appliance switched on and off toprevent activating the time delay every time the appliance is switched on.

Connection:CAUTION: IF THE AVS IS ALREADY WIRED, MAKE SURE IT IS DISCONECTED FROM THE MAINSBEFORE YOU DO ANY OF THE FOLLOWING;1. Remove the bottom cover to obtain access to connection terminals. To remove bottom coverremove the two white caps and then undo the two screws.2. Remove the two cable glands and then re-insert them so that the cable gland is external.3. Insert cable from the mains supply through the cable glands of the AVS30 and connect to theConnector terminals. (Refer to connection terminals layout diagram on next page).4. Insert cable to appliance through the C ordgrip Bush and connect to the C onnector terminals5. Tighten the C ordgrip Bushes and return the front cover and two screws and screw caps.PLEASE ENSURE NOT TO TIGHTEN CONNECTION TERMINALS EXCESSIVELY.NOTES:* In the upper compartment of the AVS, you will find a fuse (see diagram overleaf). The fuse isnot for the load. I t is a spike protection fuse. R eplace if it gets damaged. (0.5A Anti Surge).To gain access to the upper compartment, ENSURE THAT THE AVS30 I S NO T CONN ECTED TOTHE M AINS. R emove the screws from the back.* The AVS must be mounted securely on a wall. Place it over one screw at the top and then usethe two mounting holes in the terminal compartment.* The supply to the AVS30 must be fitted with a 30A HBC fuse or less.
