Note on start-up
Attention
:
Make sure that following points are checked prior to making connection to power supply and switching on
the controller:
•
Is the controller casing properly closed with all screws tightened?
•
Are all plug hooks engaged / firmly screwed in place?
•
Are all cables and glands in proper condition?
•
Is operation for the INTENDED USE made sure?
•
Does the supply voltage specified on the controller match the local supply system?
•
Does the supply frequency specified on the vibratory drive match the local supply system?
•
Is the correct mode set on the controller?
•
(See description under "Modes of Operation")
•
Is sufficient cooling of the controller ensured?
•
Is the controller mounting vibration-free?
Only if you can clearly answer all the above questions with "Yes" should the controller be put into operation.
Attention:
Set the controller to minimum output before switching-on for commissioning or start-up after repairs or
replacement of controllers/vibratory drives. Then watch proper operation while the output is increased.
4.1.
Modes of operation
RNA vibratory drive systems employ mechanical spring vibrators which are set to a vibrating frequency near the mains
frequency or near double mains frequency depending on weight and/or size.
This is why two modes of operation are possible:
Mode 1:
Asymmetric half-wave mode:
The vibrating drive operates at mains frequency.
Mode 2:
Symmetric full-wave mode:
The vibrating drive operates at double mains frequency.
To assist the operator the cable glands on the drive connector are colour-coded.
Mode 1:
black
Mode 2:
grey
In terms of the vibrating frequency this means:
Mains frequency 50 Hz
Mains frequency 60 Hz
