The S660 preset counter fits a 1/8 DIN standard cutout and is perfect for tight spaces, extending
only 3.24" (82mm) behind the panel. The unit is UL listed. The unit is for indoor use at altitudes
up to 2000m, temperatures between 0° and 40°C, and installation category III, pollution degree
2.
The counter is powered from 120 or 240 VAC. The nonvolatile EEPROM retains all programming
and count information when power is removed or interrupted.
Display scaling, preset values and all menu functions are easily programmed from the front
panel, following easy-to-use word prompts. Front Panel Reset Disable and Password Lockout
Protection features guard against unauthorized or accidental changes.
The counter accepts count rates up to 20 KHz and pulses from different types of sensors,
including Quadrature, CMOS or TTL circuits and PNP or NPN devices.
The optional, field-replaceable, single/dual relay module enhances the counter from a passive
display device to an integral control element for your application. Outputs may be controlled by
count values with independent reset operation. The counter has latching, boundary or timed
(0.01 to 599.99 seconds) alarm output modes. An optional 12 VDC (100mA) excitation output
module can provide power for external sensors.
The S660 1/8 DIN counter requires a standard 1/8 DIN panel cutout of 1.77" (45mm) high by
3.62" (92mm) wide. To install the counter into a panel cutout, remove the clips from the side of
the counter. Slide the counter through your panel cutout, then slide the mounting clips back on.

Figure 7. Standard Input Module Default Settings
DIP switch SW1, figure 7, is used to set up the counter to conform to the electrical characteristics
of the sensor or signal being detected. Switch positions 1-3 configure channel B, while switches
4-6 configure channel A. These switches select bias (threshold voltages), low pass filter (enable/
disable) and sensor type (Sink or Source).
Refer to the documentation that accompanied the sensor for related information. The sensor
can most likely be matched to one of the typical switch settings shown in figure 8 and figure 8a.
Note: The input boards are designed so that selecting sourcing or sinking is based on the
type of sensor that is being used. If a PNP (sinking) sensor is being used, set the input
board for sinking also (switches 3 and 6 = OFF).
If channel B is not used, default settings for switch positions 1 through 3 should be selected.
Default settings are provided in Table 2.
The Input module also provides for a user input signal. On the S660, this input serves as a count
enable/disable control. Connecting User to Common will disable counting.
The S660 can accept inputs from many different sensors. The A and B channels may be
configured independently as shown in Table 2. Figures 8 and 8a have examples of some typical
sensors and the wiring connections that would be used.
Table 2. Standard Input Module DIP Switch Settings
The Quadrature / Universal Input Module has two operational modes: Quadrature mode and
Standard mode. Quadrature Mode is selected by positioning JP1 and JP2 on pins 1 and 2.
Standard Mode is selected by placing JP1 and JP2 on pins 2 and 3 (see Figure 10 for details).
The Quadrature mode supports a wide range of encoders including the Simpson SE series.
While in Standard Mode, this module works similarly to the Standard Input module. In addition
to the quadrature signal, the quadrature card allows a technician to select a rising or falling
edge trigger for the count input signal. The technician is also able to determine the polarity of
the user input.
The Input module also provides for a User input signal. On the S660, this input serves as a
Count Enable/Disable.
NOTE: If B channel is not going to be used, use the default switch settings for SW1 positions 1
through 3. Default settings are provided in Table 3.
In both modes, the state of the user input signal can be selected as active high or active low.
DIP switch SW1 congures the counter to match the specications of the accompanying
sensor. When shipped from the factory, the counter is set for X1 quadrature, as shown in
Figure 10 and Table 3:
The Excitation Module can supply 12 VDC at up to 100 mA for external sensors or encoders.
This excitation is isolated from the counter internal logic supply.
When using sensors or encoders that do not have a signal return or imply a signal return that
is in common with the supply voltage, a common attachment that ties the excitation supply to
the logic input common may be required.
Examples of this appear in gures 8, 8a, 11 and 12.
The up and down keys navigate through the available

In the Programming Mode, the S660 will return to Display Mode automatically if a key is not
pressed within 120 seconds (2 minutes). The menu is comprised of three levels: Setup Menu,
Function Menu and Option Edit Menu. Figure 17 illustrates the three levels of the menu
system.
Password Entry Entry (Pass) and changing of the password (Chpass) are similar to editing a
numerical parameter. See Numerical Value below. If the password has
been set to a value other than “000,” entry of the proper password is
required to access the remainder of the menu.
Setup MenuAt the first level of the menu, the arrow keys navigate up or down through
the available Menu selections.
Function MenuThe second level of the menu contains the functions or software param-
eters that need to be configured for the counter to operate properly.
Option MenuContains either Choice Lists or Numerical Values for configuring the func-
tions of the counter.
Choice ListA choice list allows selection from a fixed number of options. A Choice List
is found in the Options section of the menu. The list is made up of the
available options for the function that is being edited. Example: Menu is
Input Setup Menu, the Function is A Channel, the Choice List is up, down,
quad, and rquad. (See Table 6)
Numerical Value A numerical entry allows the changing of set point values, scale values,
There are two start-up modes for the S660 counter. The default start-up mode will be used every
time the counter is powered up by the user. There is one alternate start-up mode that will allow
the operator to return the counter software functions to factory default settings.
The alternate start-up modes can only be accessed by pressing and holding certain keys during
the power up sequence.
•Press and hold both keys on the face of the counter
The next category in the Programming Mode is the “Input Setup.” Here you can adjust the A and
B channels to the appropriate count modes.
The A channel input may be selected as an Up, Down, Quadrature or Reverse Quadrature*
input.
As an Up channel, pulses applied to the A input are added to the display. In Down mode,
subtraction occurs. Note that when using Quadrature inputs, appropriate hardware (jumper)
settings may be needed.
* The Reverse Quadrature input allows the user to reverse the count direction of the encoder in
software instead of having to rewire/remount the encoder.

The B channel may be set as Up, Down or Direction. In the direction mode, the B channel is no
longer a count source, but controls the count direction of the A channel input. This state control
works as an ‘exclusive-or’ with the channel A direction. Thus, if B input is in the ‘Down’ state and
A channel is set to Down, pulses at the A input will increment count.

4.3Scaling and Decimal Point Position
(Count Setup)
Prescale
The S660 counter allows for prescaling of display values. Prescaling allows the counter to
display a more accurate number than its 6-digit capacity might otherwise allow by making the
positive count the most significant digit.
Generally speaking, the smaller the scale value, the more accurate the count will be. The S660
has four prescale values, 1.0 (default), 0.1, 0.01, and 0.001.
An example of this application is as follows:
A 600 pulse-per-revolution encoder is used to measure cable before it is cut to the proper length.
There is a wheel (one foot in circumference) attached to the encoder, in direct contact with the
cable. The user wants to see the counter display feet to 1/100' accuracy (to two decimal points).
With the default prescale of 1.0, one rotation of the wheel would be displayed on the counter as
00.0016'. (1/600, where 1 is the number of feet as shown by wheel rotation and 600 is the
number of pulses per revolution.) However, by using a prescale of 0.01, the resolution has been
multiplied by 100, allowing the counter to display 0.16667, increasing the accuracy of the

prescale is selected to accept the value and proceed to the next parameter, Scale.
User-defined Scale
The S660 also allows for a user-defined scaling multiplier.
1)To access the user-defined scaling parameter, enter the Programming Mode, and
press T until the count setup menu category is reached. Press .

selected to accept value and proceed to the next parameter, Decimal Point.
To calculate the scaling parameter, use the following scale formula:
Display = Multiplier (Pulse x Prescale x Scale x Decimal Point)
If the scale value isn’t known, use the following formula:
For the example we used, the scale value is:
SCALE =
DISPLAY x DP

Again, use Appendix B to make proper selections for subsequent parameters.
5)When all selections are entered and accepted into counter memory, counter will
proceed to next menu category, Set Point Setup.
The S660 has four set point parameters and a special value referred to as Reset Position.
The Reset Position can be referred to as Count Reset Value.
SP1 and SP2 are used only with Output 1, and SP3 and SP4 are used only with Output 2.
The SP1 and SP3 parameters are used as Latched or Timed “trigger” values. When a Boundary
Output is selected, SP1 and SP3 become the low boundary values.
The SP2 and SP4 parameters are used as high boundary value or ‘turn-off’ values when used
with other alarm types (i.e. latched until SP4).
The values for all set points are -99999 to 999999. The decimal point will appear according to
the current decimal point setting.

The S660 has the capability to perform a Count Reset event based upon various conditions.
When Auto Reset occurs, the outputs will return to the deactivated status and the displayed
count will return to the value stored in the Reset Position (rstpos) function. This feature is used
in cut-to-length or other applications where an automatic repetitive cycle is established.
There are seven options for the Auto Reset Mode: Disabled, at one of four set points, or after an
output times out.
