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 30 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. The counter has latching, boundary or timed (0.01 to 599.99 seconds) output modes.

An optional 12 VDC (100mA) excitation output module can provide power for external sensors.

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 (switched 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 S661, this input performs a Display Hold. While active, the rate value shown on the display is “frozen.” Internal measurements and output controls continue to operate.

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.

While in Standard mode, this module works similarly to the Standard Input module, with the added capability to selectively invert A, B, and User input signals. The Input module also provides for a User input signal. On the S661 this input serves as a Display Hold. While active, the rate value shown on the display is “frozen.” Internal measurements and output controls continue to operate.

NOTE: If B channel is not going to be used, use the default switch settings for

4) Press until oput 2 setup is displayed to make similar selections for Output 2

ENTER

Mode.

5) When all selections are entered and accepted into counter memory, counter will proceed to next menu category, Set Point Setup.

4.5 Set Point Parameters (Set Point Setup)

The S661 has four set point parameters and an Offset Value.

SW1 positions 1 through 3. Default settings are provided in Table 3.

11 28

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 value.

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.

4.4 Output Control Modes

The S661 supports two independent output channels with four modes of operation: disabled, timed, latched and boundary.

Output Type Description

Disabled Output

The output channel is inactive.

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:

Denotes module

position 1 at rear

of counter

Timed Output

Latch Output

Boundary Output

The timed mode activates an output when a set point or ‘trigger’ condition is reached. Once active, the output is held for a specified delay period. The delay may be between 0.01 and 599.99 seconds.

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 nonretriggereable 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 encountered (SP1 for output 1, SP3 for output 2).

Once activated, the output is held and can be

deactivated only when the specified Latched Until

condition is met. The Latched Until conditions can be seen in Table 10.

The Boundary mode differs from the other output

types in that it allows the counter to have an output

activate/deactivate automatically within a specified range.

Boundary mode activates an output when the

count is between the specified low and high set points (SP1/SP2 for output 1, SP3/SP4 for output

2.)

Table 9. Rate Example The input frequency can be linearly scaled using the Scaling Multiplier, Offset and Decimal Point. The rate channel has an offset value as well. To illustrate, the following example will be used:

1) Multiply Input Frequency by implied Mode multiplier 10000 x 1= 10000

2) Multiply by user-specified Scale:

3) Discard all digits to right of decimal place: (If number is larger than six digits, it will not fit in the display) 5000

4) Apply the user-specified DP location:

50.00

5) Add user-specified Offset location:

250.00 - 100.00 = 150.00 (That is what will be seen of the display) The following notation may be used to describe this behavior: Display = INT [Fint x Scale] DP + Offset

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.

The Single and Dual Relay modules can activate circuit loads of up to 5 amps at 250 VAC. A Form C configuration allows use of normally-open (NO) and normally-closed (NC) circuit action.

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 displayed count is too large for the counter to display. Since the internal count

buffer is much larger than the display, the

counter will maintain accurate count and control well beyond the display value.

Raw Count Overflow: The number of count pulses has exceeded the counter’s maximum internal value (2,147,483,648 or

-2,147,483,648)

Math Overflow: A large scale factor in

combination with large raw count has exceeded the counter's maximum internal value (+2,147,483,648 or -2,147,483,648)

Watchdog Fault: The counter did not experience an orderly power-down. This can

happen by exceeding the maximum

allowable count speed for a sustained period of time.

In the Programming Mode, the S661 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.
