Firmware Version and Update
This manual covers operation of firmware version 1.09 and later. The unit’s firmware version is viewablefrom the power on display screen, described following. It is indicated as “REV x.xx”.
This AE-1000 firmware can be updated if needed by following the AE-1000 firmware update instructions
listed on the SBS website at https://accretechsbs.com/.

SBS System – AE-1000 Operation1

System Overview
The AEMS system consists of an electronic control and either one or two acoustic emission (AE) sensors.
The AE sensors are mounted on the grinding machine and located to detect high frequency acoustic
emissions generated in the machine structure resulting from wheel contact during the grinding or dressing
process. By monitoring the level of these signals referenced against known background levels at the same
frequency, key events can be automatically and quickly detected on the grinding machine as they occur.
These events include: Initial contact of the grinding wheel to the dresser or work-piece (gap control),abnormal or severe wheel contact (crash protection), or assurance of either a maximum or minimum degreeof wheel contact thoughout the dress or grind cycle (process monitoring). These events are reported by theAE-1000 via both the hardwire and software interfaces, and the unit’s display. Machine CNC controls canbe programmed to use this information to eliminate Gap dwell time, protect against damage resulting frompart crash, and monitor the quality of the grinding and dressing process.

System Installation
System Connections
The Back panel of the AE-1000 is shown below. There are two 4-pin circular connectors on the rear panel
for connecting the acoustic sensor(s). The first sensor position (S1) can be used to monitor both M2 and M1,
while the second optional sensor connector (S2) can only be used to monitor M2. In cases where one sensor
is to be used, connect to S1.

Acoustic Sensor Location
Choose an appropriate sensor location on the grinder for testing. The Sensor must be mounted to the machine
casting or some other rigid machine structure. Do not mount acoustic sensors on thin or loosely attachedmachine components such as wheel guards. The mounting spot should be reasonable flat, and must be freeof foreign matter such as swarf. Paint removal is advisable but not required.
The critical issue to be considered in placing the sensor is acoustic transmission quality. The sensor should
be location on a rigid part of the grinder so that the high frequency noise resulting from contact between thewheel and work part, or between the wheel and dresser unit, will travel to the sensor with minimal loss of
signal. Signal loss will occur both with distance traveled through the machine structure, and especially witheach part to part mating junction in the machine. What is desired is a short path of travel for the acoustic
2

SBS System – AE-1000 Operation

signal, through as few parts of the machine as possible, with all parts of this travel path being rigid, solid, andclosely coupled and firmly mated portions of the machine structure.
For Bolt on sensor, it is advisable to use an instant adhesive (Loctite 401 or equiv.) to try some different
mounting locations, until the best location is found.
It may be possible to mount one AEMS sensor on the spindle housing, near where the balancer sensor would
be located, and use this location for monitoring both Dressing and Grinding. If this does not work on aparticular machine structure, the alternative is to mount one sensor on the dresser structure for dressing
monitoring, and another sensor on the tailstock, or other rigid portion of the part holding structure of themachine, for grinding monitoring. Two sensors can be used simultaneously by the AEMS system.
AE Sensor Types
A variety of Sensor configurations are available to fit you installation requirements. The Main types of
sensors are pictured below. Each sensor type is available in various models and the user should consult the
SBS Product catalog for details on all available models.

Bolt-on Sensor

Non-Contact Sensor

Fluid Sensor

Bolt-On Sensor – The sensor is attached by use of a screw directly to the machine structure, near the contact
point between the grinding wheel and the work piece or the wheel dresser.
Non-Contact Sensor – The sensor comes in two parts to allow mounting directly to the rotating wheel ordresser spindle. A rotating part is mounted to the spindle to pick up the AE signal from wheel contact. A
non-rotating part is mounted directly opposite the rotating part, where the AE signal is detected andtransferred to the AE monitor.
Fluid sensor – The sensor allows detection of AE signal direct from the work piece or the wheel. A fluid
stream (usually the filtered machine coolant) is directed to flow onto the target area. The AE signaltransmitted up the fluid stream is detected by the sensor.
Balancer mounted Sensor – The sensor is integrated into Non-Contact mechanical external or internal SBS
balancers.

Explanation of M1 and M2
Two separate monitoring parameter sets (M1 and M2) are provided for monitoring the results of distinct
processes on the grinder. A process is distinct if any of the contributing factors change that would influence
the AE signal intensity or timing generated from wheel contact. This would include a change in any of thefollowing: AE sensor location, grinding wheel size or type, dressing unit, work piece, feed rates, wheel RPM,
and coolant type. Setup parameters are stored separately for each parameter set and a single output Trigger
Level can be set independently for M1 and M2. M1 will be associated with the S1 (sensor #1), and M2 will
be associated with S2 (sensor #2) if connected, or with S1 if only one sensor is installed.

Quick Setup Guide
You can press
and run the Learn Cycle to set Frequency, Gain, and Sensitivity, or you can manually
set these using the following instructions.
Set Frequency


Press



Press
(this will save any change to the Gain setting) to enter the Frequency screen. A display of
the four selectable frequency bands is shown. Run grind or dress cycles until wheel contact produces a
response on the AE signal bars for each frequency. All four bands are likely to saturate the display whencontact is first made. This is okay, indicating that the gain should be reduced.



Press



Run another grind or dress cycle at the new Gain. Repeat the process of reducing gain and running cycles
until the most responsive frequency is identified. Change theto that frequency (1-4). Press.

. Use the arrow keys to turn the Gain up to maximum of 77 (this is the factory default).

to return to the Gain setup screen. Adjust the gain down and press

again.

Set Gain and Crash Sensitivity


Stay on theGain screen. This display shows a full scale (1-100%) AE signal bar graph with the Crash
indicator always at 97% of full scale relative to the current Gain setting.



Keep running cycles with the desired infeed amount and adjust theGain setting down or up until you
determine the proper gain level. This should be high enough that you see a change in the graph whennormal wheel contact is made, but low enough that a normal cycle will not accidentally exceed the Crash
limit. The Crash output signal level is also set during this process.



Press

to save any changed gain settings, thenCancel to exit to the main screen.

Set Gap Trigger Point

Manipulate theZoom and
Shift settings while running grind cycles to place the sensor’s“activity zone” into the screen at an acceptable scale.

Move theTrigger Point icon into the screen area by pressing the button, so that the Trigger output
will be actuated by the appropriate level of signal level.

Once you’ve performed this setup, the AE-1000 should operate successfully as a gap/crash monitor.

SBS System – AE-1000 Operation

CNC Signal TimeThe arrows buttons are used to change the CNC output time, displayed in increments of 5 milliseconds(range 10-250). This sets the minimum hold time that the solid state relays are held opened or closed toindicate an event. Important – The purpose is to make an event's signal last long enough to assure signal
detection by the machine control used. The factory default settings are 1 msec, but PLCs or similar devices
typically will monitor at timed intervals of about 5 msec. In such cases the signal time must be set to exceed
the polling cycle time. This setting will affect the GAP, LIM1, LIM2, and (if not latched) CRASH outputs
on the hardwire interface.

CNC Crash Latch
The arrows buttons are used to toggle the Crash output status between latched and unlatched. This option
sets how the CRASH output will react to crash conditions.

OFF CRASH solid state relay is not latched, subject to ON/OFF times like GAP, LIM1, and LIM2.
ON

Crash condition closes the CRASH N.O. solid state relay until it is reset by any of the following: (1)The hardwire interface RESET CNC input (2) The software interface “error clear” command (3)Pressing the
button when the Crash error screen is displayed.

Trigger Point
The arrow buttons are used to move the Trigger Point relative to the AE signal bar. The trigger point symbol▼ is at the top edge of the screen and flashes with each arrow button push as it also moves. The
corresponding AE signal trigger value is displayed next to thesymbol. This sets the corresponding
level at which the CNC hardwire TRIGGER output activates.

Shift Display
The arrow buttons are used to shift the AE signal bar and Trigger Point left or right by 10 pixel (4% of scale)increments. This setting only affects the display and has no effect on the Trigger Point setting.

The shift value is displayed next to thethe left edge of the screen.

symbol. The shift value is the signal level which corresponds toZoom Display
The arrow buttons are used to either expand or contract the AE signal bar by approximately 10% increments.
Zoom normally expands or contracts the display about the left edge of the screen. When the zoom expansion
includes the maximum scale value, the display will expand and contract about the right edge of the screen.

The zoom value is displayed next to thesymbol. The zoom value represents the expansion above thecurrent gain level (maximum zoom plus gain is 77). The minimum zoom value (0) shows the full scale.

Hardwire Interface
Interfacing the SBS Balance System with a CNC or
PLC machine controller is supported via a hardwire
interface or software interface. The hardwire interface
is provided via a standard DB-25 connector located on
the rear panel of the AE-1000, while the Softwareinterface is supported via the USB connection.
Because of the many possible variations andconfigurations of cabling required for such aninterface, it is left to the operator to supply thenecessary cable.
When designing an interface for the SBS System, it
is important to understand that the grinding
machine's controller must operate the AE-1000. It
is not possible for the AE-1000 to control the grinding
machine.
Carefully read this entire manual before attempting tointerface the AE-1000 with any machine controller.

Hardwire Control Interface
The hardwire interface consists of three sections:interface power supply, the inputs, and the outputs.

TR- NC

SUP-COM
Shell (Shield Ground)

The interface power supply is provided exclusively for use with the hardwire interface inputs. It consists ofthree common pins and one output pin. The common pins are internally connected to chassis and earth
ground. The output provides a maximum of 30 mA at approximately +15VDC. Any external power used
for interface I/O must be from a SELV (Safety Extra Low Voltage) source or supply.
The three inputs provide noise immunity and robustness. The inputs are activated by being pulled high, either
by connection to the AE-1000 hardwire interface power supply output or by connection to a customer
supplied signal. Activating the inputs requires at least 8 mA at a voltage between 10 and 26 volts, AC or+DC, referenced to the AE-1000 hardwire interface power supply common. The inputs are deactivated byremoving the connection to the power or signal source.
The four outputs consist of optically isolated, single-pole/double-throw solid state relays. These solid state
relays may be used to supply an output signal by connection to a voltage source supplied by the customer.
The contacts are electrically isolated from all other circuits and are rated for 24 Volts DC or AC, 50 mA
maximum. Inductive loads must be protected against flyback to 50VDC.
The three contacts of a single-pole/double-throw solid state relay are referred to as “normally open”,“normally closed” and “common”. The term “common” in this sense does not imply connection to power
supply commons. The term “return” is used below to indicate the common contact of the relay.

AEMS Analog Output
The analog output voltage is presented at pin 2 of the 25 pin CNC connector of the AE-1000 system. Pin 1 is
the ground reference for this voltage. The analog output on the AEMS system is not calibrated to a fixed
level. The gain of the system is scaled so that the analog signal output always falls in the 0-10 VDC range.
This scaled gain is needed to accommodate the huge variation in signal level that can be measured on various
types of grinders with different applications and sensor placements. This scaled gain corresponds to the gain
used for the display of AE level on the front panel.
The gain is set during the Gain Setup operation. The CRASH output closes when the analog output is at
approximately 97% of full scale (about 9.7 V). The TR output closes when the analog output is at a voltage
proportional to the Trigger Point location on the display when in the Gain Setup.

AE-1000 System Connection Diagram
ANALOG OUTSoftware (USB) Interface
The AE-1000 Basic Acoustic Monitoring System provides a software interface via a Full Speed USB device.
The software interface allows the same control capability as the hardwire interface plus system statusmonitoring and setting of parameters.
Interfacing
The software interface provides a serial interface emulation which connects the Control to a Windows
computer over USB. When connecting via USB, Windows will assign a COM port to the control. If the AE1000 is not automatically assigned a COM port, a driver for Windows installation of USB-Serial
communication is available on the SBS website at www.grindingcontrol.com. COM port assignment is
controlled by Windows. The port assigned can be determined by viewing Windows Device Manager. Use
HyperTerminal or other serial communications software to interact with the Control over USB connection.
Software Commands and Responses
When the USB interface is attached, the following message is transmitted via the software interface.

response to D, G, or A. After a Start, the data value will betransmitted approximately every 100 ms.
<ESC>CG<CR> Set Parameter Set to M1.
<ESC>CS<CR> Start Cycle.
Cycle data. D or G indicates D(M2) or G(M1) value. dddd is AE
level in dynes. These will be sent whenever a cycle is running.
There will be no response if the command is not allowed.

<ESC>CA<CR> Abort Cycle.
(no response)
Level request/change of indicated parameter set: D or G mustmatch the current parameter set[D(M2) or G(M1)] or thecommand will respond with Q. Levels are tttt(dynes) for Trigger
level, gg for Gain Level (0-84), f for Frequency Band (1-4),
ssss(dynes) for Shift, zz for Zoom level (0-84), rrr for Min output
time (10-250), and h for Crash Latch setting (0:off, 1:on). Settings
are different for each parameter set: D(M2) or G(M1). Commas
indicate which setting(s) to change. Blank settings (those without
values) will not be changed. Commas after the last desired
setting are not required.
<ESC>LD<CR> Request Current Levels of parameter set D(M2).
Level of current settings response: D or G echos the current
parameter set[D(M2) or G(M1)]. Levels are tttt(dynes) for Trigger
level, gg for Gain Level, f for Frequency Band, ssss(dynes) for
Shift, zz for Zoom level, rrr for Min output time, and h for Crash
Latch setting (0:off, 1:on). Settings other than Min output timeand Crash Latch are different for each parameter set: D(M2) orG(M1).
