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 sys-
tem?
• 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 re-
pairs or replacement of controllers/vibratory drives. Then check for proper operation while the
output is increased.
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:
Vibrating frequency
50 Hz ≙ 3000 min
-1
Vibrating frequency
60 Hz ≙ 3600 min
-1
Vibrating frequency
100 Hz ≙ 6000 min
-1
Vibrating frequency
120 Hz ≙ 7200 min
-1
