INTRODUCTION
The Proton Products SL mini and SLR mini series of laser speed and length gauges provide highly-
accurate, non-contact speed and length measurement.
SL mini series gauges offer speed and length measurement for unidirectional production lines.
SLR mini series gauges offer speed and length measurement for bidirectional production lines. The
gauge senses the direction of motion and will automatically increment or decrement the length
accordingly. SLR mini gauges are thus suitable for production lines that undergo direction reversals or
stationary (zero speed) periods.
Compared to traditional contact wheel encoders, SL mini / SLR mini non-contact speed and length
gauges offer the following advantages:
Capable of measurement at much higher speeds and accelerations
No slippage
Greater accuracy
No wear or damage to the measured object
Solid state design results in higher reliability and MTBF
RS-232 and Ethernet communication interfaces are installed as standard for straightforward
connection to computers or PLCs. One optional industrial standard communication interface
(PROFIBUS, EtherNet/IP or DeviceNET; replaces the standard Ethernet interface) may also be
installed in the gauge.
User configurable digital inputs are provided as standard to reset gauge measurements and trigger
printing. User configurable digital outputs are provided as standard to signal gauge status and preset
length reached.
PRINCIPLE OF OPERATION
SL mini series unidirectional speed and length gauges illuminate the measured surface with a
precisely pitched interference pattern created by the intersection of two laser beams. The alternating
bright and dark interference fringes modulate the light scattered by the object with a frequency
proportional to the object speed. This scattered light is detected by a photodiode and the electrical
signal digitally processed to determine the frequency and hence the speed. Object length is then
calculated by integrating the speed measurement over time.
SLR mini series bidirectional speed and length gauges extend this principle by using a high-frequency
Bragg cell modulator to illuminate the measured surface with a scanning interference pattern, which
generates an oscillating light signal even when the object is stationary. Direction of motion is
determined by whether the scattered light frequency is higher or lower than the stationary frequency.

MECHANICAL INSTALLATION
Stand-off distance and depth-of-field
For best accuracy, locate the measured object at the specified stand-off distance to the
gauge.
Speed and length measurement is possible for objects located away from the specified stand-
off distance but still within the depth-of-field; however the measurement accuracy may be
degraded by the reduced signal strength.

MEASUREMENT DIRECTION
SL MINI UNIDIRECTIONAL SPEED AND LENGTH GAUGE
The unidirectional SL mini speed and length gauge interprets motion in either direction as a positive
speed and an increase in length, thus correct length accumulation requires that the object must only
move in one direction (reverse motion will incorrectly cause the length to increment, not decrement).
Length measurements during line stoppage may exhibit a positive error due to microscopic vibration
of the object; hence it is recommended that the “Length hold” function on the SL mini logic input is
activated by the line controller when the line is stationary to temporarily suspend speed measurement
and length accumulation.
For production lines that require correct length accumulation during direction reversals or line
stoppage (without using the “Length hold” function), it is recommended that the SLR mini is used.

Mechanical mounting
It is preferable for the gauge to be mounted in isolation from the machine or production line using a
precision base plate fitted to a mounting arm (if this is not possible then the gauge must be mounted
on rubber vibration isolation mounts).The mounting arm should be kept as short as possible to avoid
vibration or twisting.
Please see the dimensional drawings for mounting hole locations.
Three M5 tapped holes are provided in the base of the gauge; select appropriate length
screws which do not bottom out in these holes.

ELECTRICAL INSTALLATION
Earth connection
Connector type: M5 bolt
An earth wire of at least 6mm2 must be attached via a crimp on ring terminal to the dedicated
M5 earth bolt on the case of the gauge.
Do not rely on the mounting bolts to provide a reliable earth path.
If a height stand is used then it must also be earthed via its own dedicated earth wire.
All earth wires should be kept as short as possible.
Shielded Cables
Use shielded cable for all signal connections.
Ensure that all cable shields are correctly clamped and electrically connected to their
connectors and metal connector shells at both ends.
Ensure that the shields of cables connecting to the end user’s equipment are clamped to
earth at their destination.

Proton Products SL mini and SLR mini Series Speed and Length Gauges Instruction Manual - issue 1s
LASER ENABLE
The laser enable input is provided for compliance with laser safety regulations.
The laser diode in the gauge may be energised only if the “LSR_EN” pin (pin 14) is connected
(via an external user-supplied switch contact) to any one of the “DGND” pins (pins 2, 15, 24).
The gauge requires a few minutes for the laser temperature to stabilise and for valid
measurement after “LSR_EN” is connected to “DGND”. For this reason, it is recommended
that the laser enable input is connected to a safety interlock that is active infrequently, such
as a maintenance lock-out key switch.
Safety interlocks that are frequently activated and require the gauge to immediately resume
measurement upon deactivation (such as a machine guard door) should be connected to the
shutter enable input (“SHUT_EN”) described in the next section.

SHUTTER CONTROL SWITCH, SHUTTER ENABLE INPUT AND SHUTTER STATE
OUTPUT
The shutter control switch (located on the front of the gauge), the shutter enable input (SHUT_EN)
and shutter status output (SHUT_ST) are provided for compliance with laser safety regulations.

The shutter control switch and SHUT_EN input blocks laser beam emission without switching
off the laser diode, thus no warm up time is required when the shutter is opened and the
gauge may be used immediately for measurements.
The SHUT_EN input is intended for connection to a safety interlock switch that may be
frequently opened, such as on a machine guard or laser safety shield.
The SHUT_ST output is electrically independent of the SHUT_EN input; the SHUT_ST signal
is taken directly from an optical sensor in the path of the shutter, thus it indicates the shutter
state even in the event of shutter actuator failure.

Normal Operation Mode
In “Normal” operation mode, the user may set two length presets (“Preset Length 1” and “Preset
Length 2”).
Whenever the measured length exceeds any length preset, the corresponding logic output assigned
to that length preset will be activated (pulled-low).
The logic output will be deactivated (floating) when:
The measured length is reset to zero by:
o Activating a logic input configured for the “Reset” function.
o Clicking the PCiS_SLmini software “Reset” button.
o Writing logic 1 to input parameter DW0.1.
The measured length falls below the length preset (applicable only to the SLR mini when the
measured length is decrementing due to line direction reversal).
Batch Operation Mode
“Batch” operation mode is used when a continuous object is being measured for marking (e.g. by an
inkjet printer) or cutting (e.g. by a guillotine) at regular intervals.
In “Batch” mode, the user may set a “Batch Length” and a “Batch Number”.
As each “Batch length” segment of the object is measured, the corresponding logic output assigned to
the “Batch Length” function will be momentarily activated (pulled-low; the activation time may be
configured by the user).
When the total number of segments measured equals or exceeds the “Batch Number”, then the
corresponding logic output assigned to the “Batch Number” function, will be activated (pulled-low).
The real-time measured segment and total lengths may be viewed using the PCiS_SLmini software or
read out of the gauge from output parameters DW6-7 and DW12-13 respectively. The current
segment number may be read from output parameter DW10.

Object Detection Mode
The “Object Detection” mode is used when measuring the speed and length of discrete objects (e.g.
multiple separate parts on a conveyor belt). The “Object Detection” mode forces the speed reading to
zero when no object is present.
An object is determined as present if the detected DC level (in percent) exceeds the “Object Detection
Threshold”; the factory default value for this threshold is 15% and it may be adjusted on the
“Measurement” page of the PCiS_SLmini software in the event of incorrect object detection
behaviour.

Length measurement behaviour
[OFF]
The gauge measures the total length accumulated across multiple discrete
objects.
ON
The gauge measures the length of each individual discrete object; detection of
the next object resets the length measurement to zero so that only the length of
the next object is measured.
* [ ] indicates the factory-default setting.
“Hold Time” behaviour in “Object Detection” mode
In “Object Detection” mode, the “Hold Time” only applies when an object is detected.
If an object is detected, but the speed signal is momentarily lost (possibly due to a surface defect on
the object), then the gauge will hold the last speed measurement for the “Hold Time” period and
accumulate length accordingly during this period.
The “Hold Time” should be set to a sufficiently long period to cover any momentary speed signal
dropouts due to surface irregularities on the measured object.
When an object is not detected, the gauge will NOT hold the last speed measurement (or accumulate
length).

Proton standard RS232 parameter access protocol
This uses a protocol to access individual parameters or blocks of parameters and is typically used in a
production line environment where the gauge is connected to a PLC or similar device.
Notes
- The parameters are split into ‘Input’ and ‘Output’ groups, the ‘Input’ parameters can be both read
and written, and the ‘Output’ parameters can only be read
- The parameter number is the same as the word address used for Profibus data; refer to the
‘PROFIBUS Master to Gauge and RS232 Input Parameter List’ for the parameter numbers
- For ‘Input’ data: when a word is defined as bits then four hexadecimal characters are required to
form the bits 15~0; when a word is defined as a data value then only sufficient characters to define
the value in decimal format, with the decimal point where appropriate, are needed; where the data
is of double word length then only the first word address is used
- For ‘Output’ data: when a word is defined as bits then four hexadecimal characters will be sent;
when a word is defined as a data value it is converted to a decimal number with the decimal point
but without leading zeros; where a double word is used then only the first word address is used to
request the data, the data in both words is automatically converted to a single value
- If a PC keyboard is being used to enter the codes then the ‘carriage return’ plus ‘line feed’ are
replaced by the Enter key

Modbus parameter access protocol
This protocol provides access to individual parameters or blocks of parameters and is typically used in
a production environment where the Proton Products instrument is connected to a computer, Modbus
connected PLC or similar device.
The parameters consist of 16-bit words (DW) and are divided into input and output groups:
Input parameters may be read from and written to and are used to configure the instrument.
Output parameters are read only and provide access to instrument status and measurement
data.
1 word (DW) consists of 2 bytes
1 byte consists of 8 bits
4 bits are expressed by 1 hexadecimal digit (0-9, A-F)
Proton Products instruments use the following Modbus format:
Modbus format
RTU (Remote Terminal Unit)

Input Parameter Write Disable
The gauge may be configured to write-disable specific input parameters when a page of input
parameters is written via the optional DeviceNET, PROFIBUS, PROFINET or EtherNet/IP
communications interface.
Input parameters may be write-disabled for the following purposes:
To simplify setup: all unused input parameters may be write-disabled to simplify the
composition of the written data page.
To avoid unintended modification of specific parameters: input parameters which must
NOT be changed via the optional communication interface (e.g. input parameters which
determine the operating mode of the gauge) may be write-disabled.
Input parameter write-disable does NOT apply to the CANbus, RS-232 or Ethernet interfaces.

Logic Input 1
Function
Rev
Direction
Activate to reverse the length counting direction.
For SL gauges, when this input is activated (for example by
a direction wheel) the gauge will decrement length.
See the “Measurement Direction” section for
information on how this logic input affects length
accumulation.
12
Length Hold
Activate to hold the length measurement by forcing the
speed measurement to zero.
The lengths read from output parameters DW6-7
and DW12-13 will be held at their values at the
instant of activation.
The speeds read from output parameters DW2-3
and DW4-5 will be forced to zero.
The frequency of the pulse outputs is also forced to
zero.
Display Hold
Activate to hold the displayed speed and length
measurements at the instant of activation for ease of
reading.
The gauge internally continues to measure speed
and length and the display will revert to these live
values when this logic input returns to inactive.
The lengths read from output parameters DW6-7
and DW12-13 and speeds read from output
parameters DW2-3 and DW4-5 will continue to
update even with “Display Hold” active.
The pulse outputs are NOT affected by this function
and will continue to correspond to the object speed.
Page 89 of 126
Proton Products SL mini and SLR mini Series Speed and Length Gauges Instruction Manual - issue 1s
Speed Hold
Activate to hold the speed measurement at its value at the
instant of activation.
The length reading will accumulate at the held
speed (including lengths read from output
parameters DW6-7 and DW12-13).
The speeds read from output parameters DW2-3
and DW4-5 will be held at their values at the instant
of activation.
The frequency of the pulse outputs is held at the
corresponding speed value.
Reset
Activate momentarily to reset the length to zero.
Activate for longer than 5 seconds to also reset the
“Reel Number” to zero.
End of Reel
Activate to increment the “Reel Number” and trigger printing
of the End of Reel report on a Zebra ZM400 printer
attached to the RS-232 port.

RS-422 compliant differential pair (normal and inverse) outputs are provided for pulse outputs
“Pulse output 1(P1A, /P1A)” and “Pulse output 2 (P2A, /P2A)”; each pulse output can thus be
connected to both single-ended and differential interfaces.
“Pulse output 1(P1A, /P1A)” and “Pulse output 2 (P2A, /P2A)” default to a 0 to +5V signal
range; if a higher output voltage is required, then an external voltage source up to +24VDC
may be connected across POUT +V and DGND to define the required voltage.
“Pulse output 1” and “Pulse output 2” may be user-configured for either independent or

Good
Reading
The gauge attempts to sample the speed of the
object several thousand times per second; the
“Good Reading” rate represents the proportion of
samples that have yielded a valid speed reading.
Higher “Good Reading” rates result in better length
accuracy, especially over shorter object lengths.
If the surface of the object is irregular then different
areas may yield different “Good Reading” rates.
For smooth surfaces a “Good Reading” rate above
50% will produce speed and length readings of
reliably high accuracy.
In short-length measurement applications (such as
inkjet-marking or cutting, with lengths in the range
of a few metres), a “Good Reading” rate of above
80% is recommended to maintain good length
accuracy.

SNR
This parameter is highly-dependent on object
material, object distance to the centre of the depth-
of-field and object speed.
For example, a metal or matt-plastic surface moving
at 100 m/minute may return a SNR > 1000, but the
SNR for a translucent plastic object may be much
lower.
The signal-to-noise ratio must exceed 80 for a
consistent and reliable speed reading.
200

-
DC Level
(%)
The DC level depends on the amount of light
received from the object and must be between 10%
and 90% for correct operation; it is held at around
30% by an automatic gain controller (AGC).
The AGC may be saturated by highly reflective (e.g.
flat, metallic) surfaces resulting in the DC level
exceeding 100%; in this case tilt the gauge (pitch,
angle γ ≠ 0) to reduce the received light and bring
the DC level below 90%.
Very narrow or low-reflectivity objects might not
reflect sufficient light for the DC level to reach 10%;
maximise the signal by locating the object as close
to the stand-off distance (i.e. centre of the depth-of-
field).
10
30
90
%
Signal
Amplitude
Highly-reflective, uneven or fast-moving objects
may result in saturation and clipping of the received
oscillating light signal.
Signal amplitudes below 80% will not incur
saturation, whilst an Automatic Gain Controller
(AGC) will accommodate signal amplitude between
80 and 99%. Signal amplitudes above 99% will still
yield measurements but at a substantially degraded
Good Reading rate.
Maintain the signal amplitude at below 80% by
tilting the gauge (pitch, angle γ ≠ 0) to reduce the
received light.

KEY SWITCH
The key switch is provided for compliance with laser safety regulations.
When the key switch is in the open-circuited (“O”) the laser diode in the gauge is DISABLED
for laser emission.
When the key switch is in the short-circuited (“I”) the laser diode in the gauge is ENABLED for
laser emission.
After the key switch is set to the enabled (“I”) position, a warm up period is required to for the
laser diode to stabilise before measurements may be taken. The key-switch is intended for
intermittent use such as locking out the laser at the end-of-shift or during line maintenance.
A removable shorting-link connects the LSR_EN pin via the key-switch to DGND; removal of
this shorting link disables the key-switch and permits an external, user-supplied interlock
switch to be wired in place of the key-switch.

APPENDIX 1: HIGH ACCURACY LENGTH MEASUREMENT OF
DISCRETE OBJECTS APPLICATION NOTE
PROBLEM
Length measurement of discrete objects moving on a production line may incur errors due to the
tracking delay / hold time of the SL / SLR / SL mini / SLR mini gauge as individual objects enter and
leave the gauge measurement spot.
SOLUTION
Use two accurately spaced light barriers connected to the logic inputs of the gauge to trigger length
measurement only after the object is in position for accurate speed measurement by the gauge.
One light barrier (LB1) is installed upstream of the gauge and one light barrier (LB2) is installed
downstream of the gauge. “L” is the accurately measured distance between LB1 and LB2.
The gauge is configured to measure length only when both LB1 and LB2 are interrupted by the
object. The gauge thus measures the length of the object minus a section corresponding to the
distance between LB1 and LB2:
Object length = L + (gauge measured length)

The distance between the gauge gauge and LB2 must be large enough to allow the gauge sufficient
time to generate valid speed measurements before the object reaches LB2 and triggers length
measurement. Distance “L” between LB1 and LB2 must also be less than the minimum object length.
IMPLEMENTATION
Light barriers LB1 and LB2 can be connected to any 2 of the 3 logic inputs provided on the gauge.
The behaviour of the gauge can be configured to trigger length measurement only when both LB1
and LB2 are blocked.
Both logic inputs should be configured to “Length hold” mode. An active logic input in “Length hold”
mode will cause the gauge to freeze length readings and force the displayed speed to zero (however,
internally the gauge will continue to accurately measure speed if an object is present). Hence each
logic input should be configured to be active when its corresponding light barrier is clear.
A “Length offset” corresponding to the distance “L” between the two light barriers can also be
programmed in to gauge. The gauge will then automatically add this “Length offset” to its length
measurement display and output.
The length measurement generated by the gauge will be ready to read by other production control
equipment when the output of LB1 transitions from blocked-to-clear (the object’s trailing edge passes
through LB1). A momentary pulse may be sent to the third logic input on the gauge to reset the length
measurement once it has been read out by other production control equipment.

Connections to the SL / SLR / SL mini / SLR mini gauge
SL / SLR / SL mini / SLR mini gauges provide three user configurable logic inputs to connect to light
barriers LB1 and LB2 and also to a reset pulse input from other production control equipment for
resetting the length measurement. Access to these inputs is either via:
1. The DB25 INTERFACE socket on the gauge.
2. The screw terminal board in an optional PSU-BOB-SL combination power supply and
breakout box (for SL and SLR gauges) or a PSU-BOB-SL-mini (for SL mini and SLR mini
gauges).

Logic input electrical characteristics
Logic inputs are referenced to pin 15 (DGND). Pin 15 is internally connected to the enclosure
earth so all voltages are also referenced to earth.
A low state (logic 0) is defined as a voltage below +3V.
A high state (logic 1) is defined as a voltage above +10.5V.
The safe input voltage range is –30V to +30V.
All inputs are internally pulled up via a 5.1kΩ resistor to an internal +15V source, thus inputs left
open circuit default to the high state.
The logic input requires a current of 3mA to pull it down to the low state.
Connection to the logic input depends on the signal source as follows:
Solid state or mechanical relay contact: connect between pin 15 (DGND) and logic input pin.
Pull-down: Connect ground to pin 15 (DGND) and signal to the logic input pin.
Pull-up: Connect an 820kΩ resistor from the logic input pin to pin 15 (DGND); this will pull down
the input to 2.5V when the pull-up is switched off. Connect ground to pin 15 (DGND) and signal to
the logic input pin. If the signal is 24V, then power loss in the resistor across the input can be
reduced by adding an 820kΩ resistor in series with the signal.
Gauge software configuration
The behaviour of the gauge can be configured via RS232, the optional AiG2 display unit or optional
PCIS software. The following three configuration settings need to be adjusted:
1. Configure both light barrier logic input functions to “Length hold” mode.
2. Configure both light barrier logic input active states to active when the light barriers are clear
(no object):

3. Configure reset logic input function to “Reset length” mode.
4. Configure reset logic input active state to active high or active low as required.
5. Configure “Length offset” to distance “L” between LB1 and LB2.
SL / SLR gauge configuration using the optional AiG2 display unit:
Navigate to the “Interface” menu and then navigate to the following submenus:
Logic input function:
Select “Length hold” for each light barrier logic input.
Select “Reset length” for the reset pulse logic input.
Logic input active state:
Select “Active high” or “Active low” for each logic input.
Navigate to the “Measurement” menu and then navigate to the following submenu:
Length offset:
Set a positive value corresponding to distance “L”.
Note: If the default resolution of 1=0.1 m (or ft or yds or inch) of the “Length Offset” parameter is too
large, then an enhanced resolution “Length Offset” of 1=0.001 m (or ft or yds or inch) can be factory-
enabled in the SL / SLR gauge.
SL / SLR gauge configuration via RS232:
The following input parameters can be programmed via RS232 (and other optionally installed
interfaces) on the SL / SLR gauge. For further information regarding the data format for programming
parameters, please consult the SL / SLR gauge instruction manual.
