OPERATING INSTRUCTIONS
MODEL DS3410 THIN SHEET DETECTOR
DESCRIPTION
The Model DS3410 Thin Sheet Detector comprises a control module in a sheet metal housing
with two probes to form a system that detects foils, stainless steel, or pre-etched double circuit
boards passing between the probes. The detector system may be used on automatic sheet
feeders where double or overlapped sheet material may jam or damage the receiving machine.
A double feed produces an output to stop the machine or signal the operator. The unit can also
be used to detect metal that is too thin as it is capable of reporting an "under" condition as well
as "over". The thickness is reported, via two form C relays, as “nominal”, “over”, “under” or
“nothing”. When appropriately configured the system retains up to eight calibration setups.

System Features
The DS3410 is a flexible gauging system with a variety of features, some of which may be
enabled or disabled through the positioning of DIP switches located beneath the control module
cover. The various features include:
•Accommodates several different probes for different mounting arrangements and area
coverage.
•Calibration on single nominal thickness (one-hit) or calibration on two different thickness
samples (two-hit) for tighter tolerance control.
•Automatic frequency selection for most applications, fixed high frequency for thinner
stainless materials.
•Independent over and under tolerance adjustment in 1 percent increments.
•Optional multiple calibration memories.
•Optional gauge windowing for gauging only a targeted area.
Control Module
The features of the control module include:
•Universal power input accommodates AC voltages from 100 to 240 volts.
•Removable terminal blocks for quick change-out of the control module.
•Separate form C relay outputs for independent reporting of OVER and UNDER conditions.
•LED indicators report the current gage states of NOTHING, UNDER, NOMINAL, and
OVER.
•Automatic setup of system gain and operating parameters.
•External or front panel calibration through a contact closure or the front panel push-button
switch.
•Four calibration memories that are selected through the SEL1 and SEL2 terminals and
optionally eight calibration memories with ENABLE configured as SEL3. These memories
allow quick changeover between materials of different nominal thickness. The memory
contents are retained even when power is removed from the unit.
•Latching OVER and UNDER outputs that are cleared by asserting the RESET input.
•Probe fault reporting on the two-digit display warns of broken or disconnected probes or
cables.

Control Module Indicators
The function of the indicators and display on the DS3410 control module are described in the
following paragraphs:
1. OVER LED is ON whenever the material thickness exceeds the calibrated nominal value by
more than the set tolerance.
2. NOMINAL LED is ON whenever the received signal is within the specified tolerances,
both over and under.
3. UNDER LED is ON whenever there is material between the probes but the material is
thinner than the calibrated nominal value by more than the set tolerance.
4. NOTHING LED is ON whenever the received signal goes beyond the measuring range of
the instrument indicating an absence of material between the probes.
5. The OVER, NOMINAL, UNDER, and NOTHING LEDs flash in succession when the
system is in calibrate mode.
6. The numeric display indicates the level of the signal from the receiving probe and reports
error or status conditions. During gauge operation the value on the display reflects the
strength of the signal from the receiving probe. Thicker materials reduce the level of the
signal reaching the receiving probe, consequently the displayed value is lower for thicker
material and higher for thinner material.
Control Module Calibrate Push Button
The push-button switch on the front panel of the control module serves to initiate the
calibration process and to make adjustments to several numeric parameters including the upper
tolerance (Ut), the lower tolerance (Lt), the relay response time (ry), the single-hit calibration
delay time (Ct), the one-shot gauge window time (Et), and reject/not reject when nothing
between the probes (rE).
To initiate calibration, simply press the push button and release it within 3 seconds.
To view the current value of a parameter, press the push button and hold it for more than 3
seconds until the appropriate parameter identifier appears on the digital display. After the
parameter identifier appears, release the push button and the current value of the parameter
displays for 5 seconds. To retain the current value of the parameter, simply allow the 5 second
display interval to elapse. The display reverts back to displaying signal strength.
To change the value of a parameter, press the push button and hold it for more than 3 seconds
until the appropriate parameter identifier appears on the digital display. After the parameter
identifier appears, release the push button and the current value of the parameter displays.
Press the push button while the parameter is displaying and the value increments, first slowly
then more rapidly. For more precise control of the value adjustment, simply tap the push button
repeatedly until the desired value is displayed. All parameters roll back to their minimum
values after reaching the maximum value. To retain the adjusted value of the parameter, simply
allow the 5 second display interval to elapse. The display reverts back to displaying signal
strength.

4
Control Module Configuration Switches
A four position switch is located on the main control circuit board beneath the front cover and
to the left of the displays (often hidden beneath the blue or gray ribbon cable). These switches
must be set to enable the features of the system that are appropriate to your application. Any
time a switch setting is changed, the control module must be powered down and back up to
install the change. The switches are read only at power up.
The functions of the switches are as follows:
Switch 1: OFF Calibrate on single only.
ON Calibrate on single and double.
Switch 2: OFF ENABLE acts to enable gauging.
ON ENABLE acts as a SEL3 input for calibration memory selection.
Switch 3: OFF The system determines the optimum operating frequency.
ON The operating frequency is fixed at a high value for very thin materials.
Switch 4: OFF: During setup the relays are set to NOT cause a reject.
ON: During setup the relays are set to a state to reject both for OVER and
UNDER .
Control Module Polarity Jumpers
Each of the logic inputs (CAL, RESET, SEL1, SEL2, and ENABLE) to the DS3410 has
associated with it a two position jumper plug located under the front cover and immediately
behind its associated connector. These jumpers allow the inputs to be driven by a sinking
(NPN) or sourcing (PNP) device. When the jumper plug is installed on the pins closest to the
connector, the input is set up for a sourcing driver. When installed on the two pins farthest
from the connector, the input is set up for a sinking driver, or dry contact between the input and
COM.
Whether set for sinking or sourcing drivers, the input is active (ON) when the signal at the
terminal is low (at COM).

APPLICATION CONSIDERATIONS
Choice of Probes
The DS3410 accommodates several models of Prime probes but is most often used with the
Type "AX" probe. The probes and their features are listed in the table below:
Probe Housing Connection Gap
AX Threaded Steel Barrel Cable 0.5” to 0.75”
P1C Smooth Steel Barrel Connector 0.5” to 0.75”
P1CS Smooth Stainless Barrel Connector 0.5” to ? (app. dependent)
Sensing performance of the AX and P1C probes is identical. The P1CS probes provide broader
sensing area and may allow greater separation of the probes.
All of the above probes are potted and completely sealed. Two probes are required with each
control.
Choice of Single or Double-Hit Calibration
The DS3410 is designed to discriminate between the standard weights of copper on printed
circuit boards. For this application, calibration on single thickness is adequate and convenient.
For printed circuit applications, the upper and lower tolerances are typically set to 20% however
they can be set tighter or looser depending upon the specifics of the situation.
For highest gauging precision, the double sheet detector should be calibrated on both a single
and a double thickness of the material to be monitored. The system utilizes the readings from
both the single thickness and the double thickness to establish the over and under thresholds of
the gauge value. The system multiplies the difference between the single and double cal values
by the upper threshold percentage (Ut) to establish the “over” threshold. It multiplies the
difference between the single and double cal values by the lower threshold percentage (Lt) to
establish the “under” threshold.
The double-hit mode of calibration is selected when Switch 1 is ON.
For both double and single-hit calibration, the values are retained even when power is removed
from the DS3410.
Using the Gauge Window Timer
The DS3410 offers a feature that can be used to limit the region inspected on printed circuit
boards or other material samples. A contact closure or low-going signal applied to the
ENABLE input of the DS3410 causes gauging to commence for the time interval set into the
parameter Et (See Enable Window Time under INITIAL SETUP). At the end of the window
time, gauging stops until the signal on ENABLE again transitions from high to low.
The window time can be set from .01 seconds to .99 seconds. When set to .00 seconds, the
window timer feature is disabled and gauging is continuous.

INSTALLATION
The installation of the components of the Thin Sheet Detector system is covered in the
following paragraphs:
DS3410 Control Module
The control board is designed to mount on the back panel of an electrical enclosure using the four
mounting slots at the edges of the enclosure. The footprint is 210 mm (8.25 inches) by 159 mm
(6.25 inches) with mounting slot locations on a rectangle 194 mm (7.625 inches) in the
horizontal and 102 mm (4.0 inches) in the vertical. Insure that the mounting screws make good
electrical contact between the module housing and the control enclosure back panel.
Avoid mounting locations with excessive heat and vibration.
Type "AX" Probes
The probes must be mounted so that they face each other with typically a 1/2" gap between the
sensing faces. The PC boards should not pass closer than 1/16" from the sensing faces. The
probe gap may in some cases be as large as ¾”. If the probe gap is too large, the unit, at power
up will never exit the setup state (will flash SU indefinitely).
The body of each probe has a 1-1/4 x 12 NF thread. They can be threaded into tapped holes or
held in brackets with jam nuts.
Type P1C and P1CS Probes
These probes operate the same as the “AX” probes but require clamp type of mount. The body
of these probes measures 9.4 inches (23.8 mm) in diameter by 2.0 inches (51 mm) long.
Probe Wiring
The cables from the probes to the DS3410 are normally run in conduit. The cables and the
DS3410 circuitry form a tuned circuit but the DS3410 is capable of determining the optimum
operating point for the specific installation. However, this requires that there be nothing in the
space between the probes whenever the DS3410 is powered up.
Control Module Wiring
All wiring for the DS3410 connects to removable terminal blocks at the bottom of the control
enclosure as described in the following paragraphs.
1. Connect 100 to 240 VAC, 50-60 Hz. power (15 watts) to the terminals labeled AC on the
leftmost terminal block.
2. Connections to the control circuit of the machine are made through the OVER and UNDER
form C relays as required. These relays are powered in the NOMINAL condition and the
diagram on the DS3410 front panel reflects the NOMINAL state. The NOTHING state
places the relays in the same state as NOMINAL.

7
3. The shielded cables from the probes to the board should be run in conduit. The receiver
probe is connected to terminals labeled RCVR on the rightmost terminal block and the
transmitter probe to the terminals labeled TMTR on the same terminal block. Since the
probes are non-polarized, the order of lead connection is not important and since the probes
are identical, it does not matter which one is the transmitter and which one is the receiver.
Connect the shield leads (drain wires) from the probe cables to the terminals labeled SHLD.
4. The OVER and UNDER relays may be operated in a "follower" mode or a "memory" mode
depending upon the wiring of the RESET input. The operational modes and required
connections are described below.
a) For "follower" mode, jumper RESET and COM together on the center terminal block. In
this mode, when an OVER or UNDER condition occurs, the appropriate relay drops out,
and the OVER or UNDER LED comes on. After the fault condition is corrected, the relay
returns to the normally energized condition and the LED goes out. Automatic reset is
normally selected to control the operation when the fault condition is automatically
removed or the DS3410 is wired into the stop circuit of the machine.
b) For "latch" mode, wire the RESET and its associated COM terminal to the normally open
contacts of a switch, relay, or controller output. In this mode, when a fault condition
occurs, the relay drops out and the OVER or UNDER LED comes on. After the fault
condition is corrected, the contact must be momentarily closed to energize the relay.
5. Calibration Enable. Connect a N.O. push button across the terminals labeled CAL and
COM. Closing a contact across these terminals initiates a calibration cycle. If there is no
material between the probes when calibration is initiated, the DS3410 waits for material to
be presented and then after a time delay determined by the setting of switch 1, actual
calibration begins.
The calibration data is stored in the non-volatile memory as selected by the signals on SEL1
and SEL2 (and ENABLE if the ENABLE input is used for memory select per the switch 2
setting). Use of the CAL input is optional since the push button on the DS3410 front panel
performs the exact same function. This input simply allows the calibration function to be
initiated remotely.
6. Switches or contacts may be connected between SEL1 and COM and SEL2 and COM to
allow selection of four different calibration memories. Calibration data is stored in the
memory that is selected at the time calibration occurs. Switching between calibration
datasets can be done at any time during DS3410 operation.
DIP switch 2 allows the ENABLE input to be used as a third memory select input. When
switch 2 is ON, the ENABLE input acts an SEL3 input providing another four memories for
calibration for a total of eight. The memories are selected through the binary combination
of signals on the SEL and ENABLE inputs as follows:
Memory SEL1 SEL2 ENABLE Switch 2
1 off off off on or off
2 on off off on or off
3 off on off on or off
4 on on off on or off
5 off off on on
6 on off on on
7 off on on on
8 on on on on

Optional SM11 Selector Switch Installation
The SM11 Selector Switch Module comes as a kit designed to mount against the inside of the
door or side panel of an industrial enclosure. The SM11 kit contains the following items:
1. knob
2. switch module
3. legend plate
4. two 10-32 stainless steel screws
5. pressure sensitive labels
Three holes are required for mounting; a 0.375 inch (9.5 mm) diameter switch shaft bore and
two 0.220 inch (5.6 mm) diameter mounting holes. The mounting holes are located one inch
off center on opposite sides of the switch shaft hole. The legend plate may be used as a
template for locating and sizing these holes.
Pressure sensitive adhesive on the back side of the legend plate provides a means of firmly
attaching the plate to an enclosure wall or door. Use the two #10 screws provided to attach the
switch module to the inside of the enclosure with the terminal block at the top.
The SM11 Selector Switch Module
requires a four wire connection to the
DS3410 control module. See diagram
below.
The selector switch has ten positions
but only the first eight are used since
the DS3410 offers up to eight
calibration memories. Positions 9 and
10 duplicate positions 1 and 2 in
DS3410 installations.
Insure SW 2 is ON and jumper plugs behind SEL1, SEL2 and ENABLE are set to the rear
positions.

INITIAL SETUP
Probe and Gap Assessment
The startup process of the DS3410 commences immediately after power up and includes
several processes which are transparent to the user except for the sequence of characters that
appear on the two-digit display.
When the unit first powers up, a sequence of characters flashes on the two-digit display.
Typically the startup display sequence includes momentary flashing of SU, followed by
momentary flashing of the selected calibration memory identifier, e.g. SL 01.
If the probes are faulty, disconnected, or cannot be identified, the controller flashes PR 01 for
transmitter probe fault, PR 02 for receiver probe fault, or PR 03 for faults on both probes.
During the startup sequence, the system assesses the readings for nothing in the gap between
the probes. For this assessment there must be no material between the probes.
When the operating conditions have been established, the two-digit readout displays a numeric
value representing the receiver signal strength.
Gauge Tolerance Adjustment
When the startup sequence has been completed successfully, the system enters gauge mode and
displays the receiver signal strength on the two-digit display. At this point the gauging
tolerances should be verified and/or set as described below: If more than one calibration
memory is to be used, the tolerances must be adjusted independently for each stored calibration.
The tolerance adjustments may be done any time except when the system is in calibration mode
(displaying “CA”).
1. Press and hold the calibration push button for 3 seconds or until the unit displays “Ut”
(Upper tolerance). Release the push button and observe the setting for the upper tolerance
value. The tolerance displays as a percentage of the single thickness and can be adjusted
from a value of 1 to 99. If the push button is not pressed again within 5 seconds, the display
reverts back to displaying gauge signal strength and the current upper tolerance value is
retained. To change the upper tolerance, tap or hold in the push button as necessary to
adjust the upper tolerance to the desired value. For detection of doubles, 50% is a good
value. Retain and store the displayed value by releasing and not activating the push button
for 5 seconds. The display reverts back to showing signal strength.
2. Press and hold the calibration push button for 4.5 seconds or until the unit displays “Lt”
(Lower tolerance). Release the push button and observe the setting for the lower tolerance
value. The tolerance displays as a percentage of the single thickness and can be adjusted
from a value of 1 to 99. Tap the push button as necessary to adjust the lower tolerance to
the desired value. If gauging for “under” is of no interest, set the lower tolerance to a high
value such as 99%. Retain the displayed value by releasing and not activating the push
button for 5 seconds. The display reverts back to showing signal strength.
Relay Response Time
The relay delay value displays in seconds and can be adjusted from zero (.00) to .99 seconds.

10
The relay delay current value can be viewed by pressing and holding the CAL push button until
the “ry” identifier appears on the two-digit display. Release the push button and observe the
current value of the delay parameter. Press and/or tap the CAL push button as necessary to bring
the delay parameter to the desired value. To retain the adjusted value of the parameter, simply
allow the 5 second display interval to elapse. The display reverts back to displaying signal
strength.
The relay delay can be used as a filter to insure the system does not respond to anomalies or fast
but unimportant changes in gauging signal.
Gauge Window Time
The gauge window timer, when set to zero, is disabled and gauging is continuous whenever the
ENABLE signal is low (unless the ENABLE input is being used for memory selection). When
set to a value from .01 seconds to .99 seconds, the DS3410 actively gauges the material
between the probes for the period of the timer whenever the ENABLE input transitions from
high to low. The gauging is on a one-shot basis.
The window interval current value can be viewed by pressing and holding the CAL push button
until the “Et” identifier appears on the two-digit display. Release the push button and observe
the current value of the window time. Press and/or tap the CAL push button as necessary to
bring the time parameter to the desired value. To retain the adjusted value of the parameter,
simply allow the 5 second display interval to elapse. The display reverts back to displaying
signal strength.
Reject on Nothing (Applies only to Version 2.4 and later firmware)
The DS3410 can be set to report an “under” condition on the relays when no material is
between the probes. Press and hold the CAL push button until the “rE” identifier appears on
the two-digit display. Release the push button and observe the current value as either 00 or 01.
When the 00 setting is in effect, the DS3410 sets the OVER and UNDER relays to the accept
states when nothing is sensed between the probes. When the 01 setting is in effect, the UNDER
relay is set to the reject state whenever there is nothing between the probes and the ENABLE
input is active. To change between the two settings, simply press the push button while the
value is being displayed and the alternate state toggles in. To retain the adjusted value of the
setting, simply allow the 5 second display interval to elapse. The display reverts back to
displaying signal strength.
CALIBRATION
The DS3410 offers two modes of calibration: 1) calibration on a single thickness material
sample, and 2) calibration on single and double material samples.
Calibration on Single and Double Thickness
For highest gauging precision, the double sheet detector must be calibrated on both a single and
a double thickness of the material to be monitored, any time prior to running. This mode of
calibration is selected when Switch 1 is ON. Calibration values are retained even when power

11
is removed from the DS3410. Depending upon selected options, the system can retain one,
four, or up to 8 different calibration settings in non-volatile memory. See the separate section
on MULTIPLE CALIBRATION MEMORIES. To calibrate on single and double, proceed as
follows:
1. Set the memory select inputs (SEL1 and SEL2 and optionally ENABLE) to select the
desired calibration memory.
2. Place a single sheet of the thickness to be gauged in the probe gap and press the CAL push
button or close a contact across the external CAL input. The unit displays “CA” and flashes
the LEDs sequentially. If the calibration on single is accepted, the unit displays alternately
"CA" and "2" indicating readiness to calibrate on a double thickness.
If the calibration is not successful, the unit displays alternately "CE" and “01” if the signal is
too weak or “CE” and “02” if the signal is too strong. Calibration may be attempted again
immediately. If calibration is not re-attempted, after 30 seconds the unit reverts to the state
prior to the attempted calibration.
3. Place a double thickness of material to be gauged in the probe gap and press the CAL push
button or close a contact across the external CAL input. When calibration is complete the
signal strength value returns to the display.
4. Adjust the gauge tolerance values if necessary (See Gauge Tolerance Adjustment under
INITIAL SETUP) and proceed with normal operation.
Calibration on Single Thickness
Switch 1 OFF, selects calibration on single thickness. For proper operation, the double sheet
detector must be calibrated any time prior to running or, optionally, the unit may calibrate on
the first board or sheet of a run. Calibration values are retained when power is removed from
the DS3410. Up to four (optionally eight, depending upon switch 2 setting) different
calibration settings may be retained in the calibration memories as determined by the signals on
the SEL1 and SEL2 (and optionally ENABLE) inputs.
1. Set the memory select inputs (SEL1 and SEL2 and optionally ENABLE) to select the
desired calibration memory.
2. Enter the "Calibrate" mode by momentarily closing a contact across the CAL and COM
terminals or pressing the push-button switch on the front of the DS3410 control module.
The unit displays “CA” and flashes the LEDs sequentially as it calibrates or as it waits for
material to come between the probes. The external contact may remain closed as the single
sheet feeds through the probe gap, but must be opened before a second sheet is fed.
3. Pass a single sheet of the thickness to be gauged through the probe gap. The sheet may be
inserted in the gap before initiation of the calibrate mode, but must be in the gap for at least
duration of the calibration delay (“Ct”) for proper calibration. The intent of the calibration
delay is to insure that a slow-moving calibration target is fully between the probes when
calibration begins.
Gauging commences immediately after calibration but only if the push button is released and
the contact across CAL and COM is released. If either of the calibration initiating signals
persists, the unit hangs in a wait state.

12
The DS3410 is capable of distinguishing 1/2, 1, or 2 ounce double or single sided circuit board
material. However, two sided, 1/2 ounce material gages the same as 1 sided 1 ounce material,
and 2 sided 1 ounce material gages the same as 1 sided 2 ounce material.
FIRMWARE VERSION
From time to time, as improvements are made to Prime products, the firmware controlling the
units is revised. When setting a unit up or troubleshooting it may be necessary to determine the
version number for the firmware installed in your unit. The version numbers begin with 1.0 and
are incremented either by tenths (1.1, 1.2, etc.) for small revisions or by the integer digit (1.0, 2.0,
etc.) for more significant revisions.
To determine the version of the firmware running in your unit, simply hold the calibration push
button in as power is applied to the unit. The revision number will be displayed on the two-digit
display alternately with the letters “Fr”. For example, Version 1.8 will flash alternately “Fr” and
“1.8”.

TROUBLESHOOTING
Should trouble develop, proceed as follows:
1. Check AC input power to the control module
2. Check the fuse, accessible at the lower left side of the DS3410 housing.
3. If the unit powers up, initializes and the LEDs indicate a response to the materials in the gap
but the relays do not switch, check that the outputs are enabled (jumper or contact closure
between ENABLE and COM) and that the relays are set to follow and not to latch (activate
the RESET input to unlatch). For most installations, simply install jumpers between
RESET and COM and between ENABLE and COM.
4. If PR and 01 flash alternately on the display, check the transmitting probe for proper
connection and continuity.
5. If PR and 02 flash alternately on the display, check the receiving probe for proper
connection and continuity.
6. If PR and 03 flash alternately on the display, check both probes for proper connection and
continuity.
7. If the unit displays SU on the display for longer than 10 seconds after power up, insure that
nothing is between probes. If no material is between the probes, decrease the separation of
the probes.
8. If SU and 04 flash alternately on the display, the probe gap is too small. Increase the
separation of the probes.
9. Power the unit down and back up again with nothing in the probe gap. Insure the numeric
display reads 99. If not, check the probe gap for a range of 1/2 to 3/4 inch.
10. A display flashing CE and 01 during calibration indicates the signal is too weak. The
probes may be separated too far or the material too thick for the detector.
11. A display flashing CE and 02 during calibration indicates the signal is too strong. The
probes may be too close together or the material too thin for the detector.
