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" must 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:
Mains frequency 50 Hz
Mains frequency 60 Hz
Cable gland colour
Mode 1
Half-wave mode
Vibrating frequency
50 Hz ≙3000 min-1

60 Hz ≙3600 min-1
Black
Mode 2
Full-wave mode
Vibrating frequency
100 Hz ≙6000 min-1
Vibrating frequency
120 Hz ≙7200 min-1
grey
Vibratory drive systems by RNA do not require the operator to take care of selecting the right operating mode.
The operating mode is determined by a code in the RNA vibrating drive connector. A wire jumper from pin 3
to 4 in the connector switches the controller to mode 2: 100 or 120 Hz. In the absence of this wire jumper the
controller operates in mode 1: 50 or 60 Hz.
The RNA vibratory drive systems come with the right code in the connector.
Mode changes are made only and exclusively via the coding in the vibrating drive connector.
(Where frequency controllers with selectable output frequency are used, an EMC metal gland and a shielded
cable are provided.)

Two sensor inputs are integrated into the controller. They enable you to implement accumulation checks,
level checks, cycle monitoring and other monitoring tasks. The following basic assignments are made:
Sensor input 1 acts on channel 1, unless otherwise programmed in menu C006.
Sensor input 2 acts on channel 2.
The sensor inputs can be evaluated only if they are activated. For sensor connection (connector XS3)
please refer to the connection diagram.
The controller has two sensor inputs which can be used for accumulation checking and/or level monitoring
purposes. You can connect sensors of type NPN or PNP.

The status outputs are used for remote diagnostics of the controller status or of the links of several controllers
with one another.
They are designed as freely available NPN-doped transistor circuits and they are floating.
With the status output READY the transistor circuit is switched through whenever the controller is connected
to power supply and switched on by its power switch closed.
The status outputACTIVE requires the same conditions for switching-through as "READY". In addition, chan-
nel 1 must be operating actively, the transistor blocks in case of ACCUMULATION, OFF or STOP. The status
outputs as well as the external enabling inputs are to be wired via plug connector XS4.
The two relays have different functions. K1 operates as a status relay parallel to the ACTIVE status output.
K2 serves either for a blowing air switch-off delay (4 sec.) or for cycle monitoring of one of the two sensor
channels.
Connections and cable entry are located on the right side panel of the controller. The terminal block is located
behind the controller side panel.

Use the following two links to set priority of the channels.
AND logic of the two sensor inputs with blowing-off the exit track.
Example:
Application:
Twin-track feeders with accumulation checker.
Solution:
Track 1 (sensor 1) full = Blow-off track 1 (relay K1)
Track 2 still clear
Track 2 (sensor 2) full = Blow-off track 2 (relay K2)
Track 1 still clear
Track 1 + Track 2 full = Bowl feeder (channel 1) stop, about 4 sec. later blowing air
stop

AND logic of the two sensor inputs without blowing-off the exit track.
Bowl feeder (channel 1) stops when both sensors are operated. Orienting air can be switched off
with delay (4 sec.) via relay K2.
OR logic of the two sensor inputs.
Bowl feeder (channel 1) stops when one of the two sensors is operated. Orienting air can be
switched off with delay (4 sec.) via relay K2.
Min/Max logic of the two sensor inputs.
The bowl feeder stops when both sensors are operated. The vibratory feeder (channel 1) will re-
start only after both sensors are cleared again.
Relay K1 operates on stopping of bowl feeder. Relay K2 operates 4 sec. later (stopping the blow-
ing air)
AND / S2 logic
Vibratory feeder (channel 1) stops when both sensors are operated. It starts when sensor 2 is
cleared again. Orienting air can be switched off with delay (4 sec.) via relay K2.
Level check for hoppers with external hopper control
Sensor 2 operates relay K1 following the delay period entered (C005). When sensor 1 is operated,
relay K1 drops out (hopper interlock).
Application:
Sensor 1 = accumulation check
Sensor 2 = level check
Relay K1 = hopper control
Level check with indicator light
Sensor 2 operates relay K1 following the delay period entered (C005) without taking into account
sensor 1 (accumulation check).
Application:
Sensor 2 is used as a level checker (e.g., LC-N 24V DC). Relay K1
operates an indicator light: Bowl feeder empty.

5.5.5. Code C008 cycle monitoring
The cycle watchdog monitors the CLEAR sensor status. The time (A 180) sets the maximum du-
ration for which a sensor is allowed to be clear before an alarm message is generated.
In case of an alarm the relay K2 is clocked on and off. Reset takes place automatically when the
sensor is operated again.
If OUT = 1 the alarm operates relay K2 (indicator light: Error) and also stops the bowl feeder. An
ERROR message appears on the panel display. Use the bottom right cursor button for reset.
If OUT = 0 thealarm only operatesrelay K2 (indicator light: Error). Reset takes placeautomatically
when sensor 1 is operated.
If A.I. = 1 relay K1 is clocked on and off in response to the alarm (switching from relay K2 to re-
lay K1).
