Yes this is UV stabilized.
Non Metallic Corrugated Conduit is manufactured to comply with relevant sections of AU/NZ
2053 and comes in Medium Dutyand Heavy Duty grades. Medium Duty products are UV stabilised.
Operative temperature range is -15°C to +65°C.
One of the main benefits of Non Metallic Corrugated Conduit is that it can be tightly coiled without effort or damage to wall sections, nor will there be any reduction in cross
sectional area. This significantlyreduces installation time in difficult situations and the number of fittings required.
How to change the display of an ATV320 to show RPM?
ATV320 series drives.
All models, All serial numbers.
Information unavailable or unclear in current literature.
The ATV320 drive cannot directly display the RPM of the motor, but we can use a custom configuration to display a number that is very close to the true motor RPM.
The drive normally displays motor speed in Hz. In order to convert this to RPM, we much enter a custom multiplier. You will need your motor nameplate information for this.
Take the actual RPM of the motor, as listed on the motor nameplate and divide that by the base Hz of the motor. An 1800RPM motor want be exactly 1800, there will be a number such as 1750 or 1760 listed as the RPM. Divide this number by the base frequency of the motor, usually 60.0Hz, to yield a multiplier of 29.3 for a 1760 motor, or 29.16 for a 1750 RPM motor.
Program parameter SDS (Scale Factor Display) under the DRC menu to this value.
Note that if you are using the keypad of the drive to adjust the motor speed (FR1 or FR2 set to A1U1), you will only be able to show the speed reference on the display, you can not switch to display any other value in the drive while using the keypad to adjust speed.
