3. Product information
3.1. Functional description
This fully automatic controller has been developed specifically to operate RNA bowl feeders or linear feeders with a
high feed rate.
The intelligent controller continuously monitors the mechanical conveyor movement and uses this signal for active
control of the vibration amplitude and thus the feed rate. This makes sure that the set fed rate is maintained irrespec-
tive of conveyor load, ambient temperature, supply voltage and supply frequency, etc.
The drive frequency is automatically controlled in a PLL circuit so that the feeder is run under optimum conditions at all
times, i.e. exactly at the resonance frequency.
The controller adapts to the connected feeder by means of an automatic calibration sequence which largely eliminates
the often laborious mechanical adaptation to the feeder.
These controllers allow vibrating motors to be operated at different mains frequencies without the need for changing
the magnets or re-adjusting the feeder mechanically.
The controller is self-protected which makes sure that neither the drive magnets nor other components will be over-
loaded. The parameters of all mechanical and electrical components are permanently monitored. In case of significant
deviations the monitoring function will output alarm messages before serious consequences can occur, i.e., it identifies
a defective spring or loose nut before further damage occurs.
This controller as two 24V DC sensor amplifiers.
Moreover, there are two optocouplers and a relay output for status messages as well as an external enabling input of
24 V DC for remote control.
3.2. Standard features
•Dynamic electronic protection covering output short-circuits and output overloads.
•Active protection of magnets and motor.
•Permanently controlled speed which ensures stable running and repeatable speed setting.
•Low maintenance of the drive system.
The automatic frequency adjustment to the changes in drive characteristics reduces the need for frequent fine
tuning of the drive springs.
•Reduced power consumption (approx. 50 %).
Motor requires less power as it runs in the resonance range.
•Flexible choice of frequency (25-150 Hz).
Drive frequency can be perfectly fine-tuned for a specific application, irrespective of the mains frequency.
•Not affected by mains fluctuations (voltage / frequency).
•Control over the entire feed system.
•2 sensor amplifiers.
oTwo independent 24V DC sensor inputs for monitoring the feeder (accumulation check).
•Speed can be set by analogue setpoint entry.
•Communication
oElectrically isolated 24V input for start/stop by external signal.
oReadiness message (optocoupler, 24VDC, 20mA)
oActive message (optocoupler, 24VDC, 20mA)
oActive message via relay contact. 250VAC, 1A
•Firmware upgrade via USB port.
•Immediate stop function by active brake monitor.
oThis optional feature stops the motor immediately in response to a stop command. This prevents a
'stop delay' and slow stoppage of the vibrating motor.This option is particularly useful where counters
are involved, i.e., where an exact number of parts is to be counted without excess parts dropping off
the feeder when the right number of parts is reached.
•Multiple calibration
•One device can be calibrated for up to 11 different motors.
•Electrically isolated 24V input for speed switching.

4.2. Mechanical installation
Planning the place of installation:
Choose the best possible position taking the following into consideration:
•Ambient temperature
•Low-vibration mounting
•Operator access to controller
•Controller location near the vibrating motor
•Cable routing
Physical dimensions
Fix the ESR2500 - 2800 controller in place by inserting two M8x40mm screws through the two holes in the heat sink
beneath the housing.
You can fix the device either directly to the feeder base plate or to the base frame of the machine.
A controller fitted directly to the feeder is exposed to strong vibration which may shorten its lifetime. It is highly recom-
mendable, therefore, to mount the controller on a non-vibrating, mechanically rigid structure such as the base frame of
a machine.
4.3. Electrical installation
Fuses
The device is internally protected by a 4A 5x20mm time-lag fuse in the mains supply line.
Mains supply must be protected by overload protection with C 16A fusing.
Earthing and supply mains
Notice
Check that supply voltage is in accordance with the data on the device rating plate.
Check if controller setting has been changed to another supply voltage or magnet voltage.
The ESR2500 / 2800 controllers are devices of protection class 1 which have to be connected to earth accord-
ing to regulations.
Attention
The cable connecting the controller with the vibratory feeder must be shielded and both ends of the shield
connected to protective earth.
The maximum admissible cable length is 3 m.

4.8. Voltage change
The ESR2500/2800 can be operated with various supply voltages and magnet voltages.
For changing the voltage you must open the controller.
Therefore, be sure to observe the safety instructions and general warning notices in Chapter 2.
You can set the controller to a mains supply voltage of 230V or 115V.
If set to a mains supply voltage of 230V the magnet voltage is always 200V.
If set to 115V mains supply you can choose a magnet voltage of 100V or 200V.
With 115V mains supply voltage it is recommended to choose a magnet voltage of 100V with corresponding magnets.
If you choose 200V magnet voltage with 115V mains supply, the mains supply voltage is doubled internally to achieve
the 200V magnet voltage. This means that the current drawn from the 115V mains supply is also doubled. This is why
this setting should be used in cases of emergency only.
How to set the controller to the different voltages is shown below.

Next to the status text the display shows the status of the external signals, starting with an asterisk "*" followed by "1"
if the controller is stopped by accumulation sensor 1, by "2" if the controller is stopped by accumulation sensor 2 or by
"R" if the controller is stopped by the enabling signal input.
If the feeding speed is controlled by an external source the active source is indicated by > followed by a two-digit code.
The codes have the following meanings:
"HS" The speed is set to High.
"LS" The speed is set to Low.
"AN" Speed is controlled by the analogue input.
"FB" The field bus controls the controller. (optional)

6. The set-up menu
You can open the set-up menu from the "Extended" screen of the main menu after entering the correct password.
6.1. List of set-up menu items
Some items of the "Set-up Menu" are optional (under preparation) and must be enabled by entering an activation
code. Accordingly, access to the submenus is blocked until the required activation code has been entered. Blocked
status of a menu is indicated by a small padlock at the bottom right of the display.
Hence, you can only enter the submenus that are activated. This makes navigation very easy because there is only a
minimum of menus you have to navigate through.
The activation codes are unique for every single controller and can be acquired by indicating the requested option to-
gether with the serial number of the device. Some options require additional cables or hardware to be installed.
Upon input of the required code activating an optional menu, the entire tree of the submenu opens up giving you ac-
cess to the parameter settings related to this option.
Notice
The parameters marked "Set-up specific" on the following pages will be stored separately for every calibra-
tion cycle.
The parameters marked "General" apply to all calibrations.
For the digital inputs and outputs you can choose to configure the function as active at High (24V) or active at Low
(0V).

6.1.1. Accumulation checker (sensor inputs)
You can connect up to two sensors to "sensor connection" XS2 for accumulation monitoring or level monitoring. See
connection diagram in chapter 4.6 and 4.7. The signal may, e.g., come from a light barrier indicating whether an accu-
mulation section is full or not. The accumulation check submenus make it possible to configure each sensor input sep-
arately.
The sensor input can be set at "inactive", "active at 24V" or "active at 0V". If the input is set at "inactive" the controller
ignores the signal. If the input setting is "active at 24V" the feeder starts when the input is energized. As soon as the
input is de-energized the feeder stops.
You can configure a start and stop delay for the sensor signal. The delay is the time in milliseconds between receipt of
the sensor signal and the response.
You can choose the sensor types NPN or PNP.
In the "Accumulation link" submenu you can link the two sensor inputs "AND" "OR" and "XOR".
If "AND" is set, both sensors must be active for the controller to stop the feeder. If "OR" is set, only one of the two sen-
sors must be active for the controller to stop the feeder. If "XOR" is set the controller stops the feeder if the two sen-
sors have different switching statuses.

6.1.2. Ramps
The start ramp (soft start) makes sure that the output voltage slowly rises from 0 to the set value on every motor start.
Too short settings of this time would lead to bumping of the vibratory feeder. Heavy feeders tend to overshoot if the
voltage is increased too quickly.
Stopping of the vibratory feeder should not normally be delayed. In some cases, however, soft stoppage may be nec-
essary to avoid misorientation of parts on the feeder stopping abruptly.
The time setpoint defines the soft start or stop duration. For example: With the Start ramp set at 1000 ms the feeder
takes 1 second to build up vibration from 0 to 100 % or 500 ms to go from 0 to 50 % vibration.

6.1.3. Display calibration
You can configure the display on the controller as required.
In the Display Calibration menu item you can set the contrast/brightness. When lighting is set at "Normal" pressing of
a button illuminates the display and after 10 seconds the light extinguishes again. When lighting is set to "On" the light
remains on and if set to "Off" it remains off permanently.
You can also select the language. (See table)
6.1.4. Communication / connector XS3
Enabling input
In the "Enabling" submenu you have the choice of setting the enabling input at "inactive", "active at 24V" or "active at
0V". If the input is set at "inactive" the controller ignores the signal. If the input setting is "active at 24V" a 24V enabling
signal is released to the controller and the feeder starts. An on-delay and an off-delay of the enabling signal can be
configured separately.
Active output
The "Active output" submenu is used for configuration of the output signal "active". You can set "Active On" or "Active
Off". "Active On" means that the signal is switched on when the motor is running and off when it is stopped. The signal
can also be delayed.
Active relay output
The "Active relay" submenu having similar functions as the "Active output" submenu is used for configuration of relay
K1.
Ready output
The "Ready output" submenu is used for configuration of the Ready output signal. You can set "Active On" or "Active
Off". Active On means that the signal is sent when the controller is energized by its power switch closed.
