FAQs - everything you wanted to know about the Omnisava …
PLEASE NOTE: INSTALLATION, CONNECTION AND ANY MAINTENANCE SHOULD BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON IN ACCORDANCE WITH CURRENT AND LOCAL REGULATIONS
What is the Omnisava?
A multifunction control designed to save water, compressed air, steam and other expensive commodities used across all industry sectors. Responding to PIR or proximity sensors, the Omnisava eliminates unnecessary waste and saves money by supplying only on demand.
Can you give some typical applications?
- In a machine shop / garage using many compressed air tools there is always costly leakage in hoses and fittings. Fit an Omnisava controlled by PIR sensor to shut off the air at the compressor when no one is about. Kills the problem dead. Function 0
- Conveyor belt production line using compressed air to dry / blow products. Fit Omnisava with proximity sensor to detect products. Shut off air when conveyor stops or when there are no products ie end of production run, line stoppage etc. Function 1, 2, 3 or 4
- Isolate toilet area, handbasins, WC's etc by installing Omnisava with PIR sensor. Shuts off water when no one is about, prevents wastage from leaks, vandallism etc Function 0
What savings can I expect?
This is very difficult to quantify as it depends on so many factors. For those factories where compressed air or water is running 247 dramatic savings of between 50 and 90% can be expected.
In most cases the Omnisava should pay fr itself well within one year.
When do I use a PIR sensor?
Use a PIR (Passive Infrared) sensor to turn off water, air, motors, heaters etc when an area is unoccupied. Can be applied to factory operatives, passengers, shoppers, staff etc etc. Read instructions carefully particularly with regard to positioning the sensor.
Can I use a normally closed proximity sensor?Yes, simply select NC on the SENSOR slide switch to invert the logic of the Omnisava input.
What's the difference between NPN & PNP sensors?
An NPN sensor shorts or sinks current from the Omnisava NPN input to -
terminal. A PNP sensor shorts or sources current into the Omnisava
PNP input.
What does the TEST button do? By simulating the sensor inut the test button enables the installer to verify the control function. Simply set a short (1-5 second) time period and push the button. The green led (and valve if fitted) will operate according to the function selected.
Can I use a microswitch or manual pushbutton instead of a sensor?
Yes, connect switch across terminals 4 & 6 (npn input) or 5 & 7 (pnp input). Set the SENSOR
polarity switch to NO or NC according to the chosen type of switch.
Do I need to connect a 'flywheel diode' across the solenoid valve?
No, the Omnisava has one built in, however an additional diode
connected correctly (cathode or band to +24v) will be quite ok.
I cannot find the function that I need ...
