ages), 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 S662, this input serves
as the secondary channel (Batch) hard-wired reset. This may be used to reset the batch
count while preserving the primary count.
The S662 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.

2.5 Quadrature Input Module
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.

The Input module also provides for a User input signal. On the S662 this input serves as
the secondary channel (Batch) hard-wired reset. This may be used, for example, to reset
the batch count while preserving the primary count.
In both modes, the state of the User input signal can be selected as active high or active
low. DIP switch SW1 configures the counter to match the specifications of the accompanying sensor. When shipped from the factory, the counter is set for X1 quadrature, as
shown in Figure 10 and Table 3: witch settings for SW1 positions 1 through 3. Default
settings are provided in Table 3.

12 VDC Excitation Module
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 figures 8, 8a, 11
and 12.

3.4 What the Keys Do in the Programming Mode
Key Keypad behavior
Output Type Description
Disabled Output
The output channel is inactive.
The timed mode activates an output when a set point
or ‘trigger’ condition is reached. Once active, the
output is held until a specified delay period. The delay
may be between 0.01 and 599.99 seconds.
Timed Output
The output will activate when the specified value is
encountered (SP1 for output 1, SP3 for output 2). If
a timing period is in progress, a new trigger does not
occur. This is referred to as a non-retriggereable
timer.
A RESET will cancel the timed output.
The latch mode activates an output when a ‘trigger’
or set point is reached.
The output will activate when the value is
Latch Output
encountered (SP1 for output 1, SP3 for output 2).
Once activated, the output is held and can be

Figure 17. Programming Menu Structure
In the Programming Mode, the S662 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 View and Option Edit. Figure 17 illustrates the three levels of the
menu system.
Password Entry Entry (Pass) and changing of the password (Chpass) are similar to edit-

Setup Menu At the first level of the menu, the keys navigate up or down through the
available Menu Categories.
Function Menu The second level of the menu contains the function or software param-

Prescale.
Prescale
The S662 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. Generally speaking, the smaller the scale value, the more accurate the count will be. The
S662 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’. 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
The up and down keys increment or decrement

negative numbers. In these cases, the most
significant digit can be made negative by
incrementing it between "9" and "0."
Saves the values as the new setting for the
function in memory and advances to the next
function of the menu automatically.
3.5 Special Start-Up Modes
There are two start-up modes for the S662 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.

4.4 Count 2 (Batch) Scaling and Display (Count 2 Setup)
Count 2 operation may be controlled in one of two ways: Dual mode and Batch Mode.
Dual Mode
In Dual Mode, the Count 2 is increased or decreased at the same time Count 1 is increased or decreased. The counter operates like two independent counters sharing the
same input signal. Each “counter” has independent scaling and reset controls.
Batch Mode
In Batch Mode, Count 2 is increased whenever an Auto Reset occurs on Count 1. The
Auto Reset parameters (see section 4.7) must be configured for the application.
The Count 2 display value is independent of the Count 1 display value. The secondary
“channel” in the S662 has its own scaling values and decimal position. The Scale 2 multiplier and Decimal Point 2 locations operate similar to that for Count 1. In addition, a

4.2 A/B Channel Options (Input Setup)
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,

When A channel has been set to either Quadrature or Reverse Quadrature settings, the B
channel internally behaves as a direction control.
2) To set the B channel:
a) In the Input Setup area, after entering the A Chan value, the display will flash be-
tween b chan and the counter’s default (dir).
b) When the display shows dir, press .
c) Use the arrow keys to change the value, then press to accept the selection and

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.

4.3 Count 1 Scaling and Display (Count 1 Setup)
Scale
The S662 counter allows for scaling of display values. Scaling allows the counter to display a more accurate number than its 6-digit capacity might otherwise allow.
Generally speaking, the smaller the scale value, the more accurate the count will be. The
S662 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
quad using the arrow keys.
c) When the selection is complete, press to accept the selection to counter memory

and proceed to the next parameter, Chan B Mode.
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.
19 20
(to two decimal points).
With the default scale of 01.0000, one rotation of the wheel would be displayed on the
counter as 00.0016’. 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
counter and allowing more accurate cutting.
1) To access the user-defined scaling parameter, enter the Programming Mode, and
press q until the count 1 setup menu category is reached.
