### Description

The Tiger 320 Series controller has four input channels capable of processing almost any input signal type. The IF10 universal frequency/counter input module uses only channels 1 (CH1) and 2 (CH2).

The IF10 input module receives and conditions an AC volts or digital input signal, via pin 1, and supplies a frequency input to CH1 and CH2 in the meter for further processing. CH1 can also be configured as an UP counter via software selection in Code 2 of the meters programming software. CH2 can be configured as an UP or DOWN counter. The UP/DOWN counter control signal for CH2 is connected to pin 4. With the frequency/counter selection header set to the COUNT position, the input module provides an UP counter output to the meter for further processing. To provide a DOWN counter, pin 4 must be connected to ground (pin 3).

Selectable on-board headers provide configuration settings allowing the sensor and signal type to be selected along with high and low-pass filtering. These selectable headers give the Tiger 320 Series the flexibility to perform dual software operations such as rate of change on CH1 and totalizing on CH2.

### Interface Configuration

### Examples

The following example diagrams show the various header settings and input connections required for a range of input sensor types.

Example 1 NPN Open-collector Output with Proximity Switch Figure 3 shows a 3-wire proximity switch taking +24 V excitation from the meter with an NPN open-collector signal output connected to the input module as frequency with no filtering (CH1 and CH2).

The input header is set to SINK connecting the signal output to +24 V via an on-board 10 k pull-up resistor. As the proximity switch is activated, the signal is forced to ground.

Figure 3 3-wire Proximity Switch with NPN Open-collector Output

Example 2 PNP Open-collector Output with Proximity Switch Figure 4 shows a 3-wire proximity switch taking +24 V excitation from the meter with a PNP open-collector signal output connected to the input module as frequency with no low-pass filtering (CH1 and CH2).

The input header is set to SOURCE connecting the input signal to a 10 k pull-down resistor to ground. When the proximity switch is activated, the input signal switches from 0 V to +24 V.

Figure 4 3-wire Proximity Switch with PNP Open-collector Output

Example 3 Hall Effect / Magnetic Pickup mV Input Figure 5 shows a magnetic pickup. With small AC signals a shielded cable should be used to avoid stray pickup.

Figure 5 HAll Effect / Magnetic Pickup mV Input

Example 4 TTL Input Figure 6 shows a TTL input. The TTL input requires the sensor header to be placed in the SINK position. In this example the TTL logic has a separate +5 V supply. The input module is configured as a DOWN counter on CH2 and a frequency input on CH1. This requires pin 4 connected to ground (pin 3) to select the DOWN counter option and the frequency/counter header set to COUNT. The digital option (LOGIC) is selected on the signal type header.

Figure 6 TTL Input

Example 5 Digital Input with DC Voltage Offset Figure 7 shows a digital input with voltage offset. In this situation the DC component of the signal is removed by selecting the AC option on the decoupling header. The digital input has its own supply voltage. CH1 reads frequency. CH2 is set as an UP counter.

Figure 7 Digital Input with DC Component

Example 6 Pushbutton Switch with Frequency & UP Counter Option Figure 8 shows a pushbutton switch with frequency on CH1 and the UP counter option on CH2. The low-pass filter header is set to

200 Hz to debounce mechanical contacts. Sensor type is set to SINK to pull-up the input signal to +24 V until it is switched to ground when the pushbutton is pressed.

Figure 8 Pushbutton Switch with Frequency & UP Counter

Example 7 NAMUR Sensor Figure 9 shows a NAMUR 2-wire proximity detector as an UP counter on CH2. Set the sensor header to NAMUR to ensure the detector has the correct output load (2 k pull-down resistor) and to protect the sensor at +24 V excitation voltage. The current output of these detectors vary in response to the proximity of the target metal.

### Converting K Factor to

### Scale Factor for Manual

### Calibration

One method of calibrating the IF10 input module is to use a frequency generator to apply a low and high input, while setting zero and span settings via the two-point calibration mode. Unfortunately, a frequency generator is not always available to a user in the field and, therefore, manual calibration needs to be carried out by changing the controllers scale factor.

Flow sensors such as paddlewheel and turbine types generate a known number of pulses for each unit of volume of fluid passing the rotor blade. This constant is known as the K factor and is used to determine the flow rate or total flow from the number of pulses occurring per second.

To calibrate the IF10 input module in applications using pulse, flow, and proximity sensors, the manufacturer provides either the K factor specified for the sensor, or a pulses per engineering unit chart (liters, gallons, feet, inches, meters, millimeters, revolution). From this information, The K factor can be easily converted to a scale factor and the scale factor manually entered into the controller.

Depending on the channel used and the type of input signal, follow the sequence of steps in one of the following manual calibration procedure sequence charts:

Channel 1:

As a frequency signal to the controller.

As an UP counter.

Channel 2:

As a frequency signal to the controller.

As an UP or DOWN counter.

### Channel 1

Frequency Input

As a frequency input to the meter, a different scale factor can be used in CH1 to suit the required engineering units. To calculate and set a new scale factor, carry out the manual calibration procedure in the following sequence:

UP Counter

As with CH1 set to frequency, a different scale factor can be used in CH1 to suit the required engineering units. The configuration procedure is identical for the first five steps, but in Step 6 the frequency input signal can be selected in software as an UP counter. To calculate and set a new scale factor, carry out the manual calibration procedure in the following sequence:

### Channel 1: Frequency Input

Step 1 Establish the K Factor The manufacturer of the sensor normally provides either the K factor specified for the sensor, or a pulses per engineering unit chart, shown in pulses per liter, gallon, feet, inch, meter, millimeter, or revolution. Either way the K factor is the same:

A K factor of 250 is the same as 250 pulses/unit for a specified sensor application

Step 2 Calculate the Scale Factor From the K factor, the scale factor can be calculated by dividing K into unity.

For example:

A paddlewheel sensor generates 213 pulses per gallon of fluid passing the rotor.

If K = 213 (213 pulses/gallon)

Then

= 0.0047 gallons/pulse = the scale factor

The resultant scale factor is then entered into the controller in the calibration mode.

The controller receives the input signal from the sensor as pulses and treats them as a frequency measurement task. The final controller display is in units of frequency, i.e. hertz, but equivalent to the flow rate scaled to the appropriate engineering units, for example: gallons/second.

A rotary encoder placed on a milling table generates 500 pulses per foot of travel.

Therefore, if K = 500 (500 pulses/foot)

Then

= 0.002 feet/pulse = the scale factor

Again, the resultant scale factor is then entered into the controller in the calibration mode. The controller receives the input signal from the sensor as pulses and treats them as a frequency measurement task. The final controller display is in units of frequency, i.e. hertz, but equivalent to the feed rate scaled to the appropriate engineering units, for example: feet/second.

Note:

If you require units per minute divide the scale factor by 60.

If you require units per hour divide the scale factor by 3600.

Step 3 Enter the New Scale Factor When you have established the new scale factor, enter the controllers calibration mode [CAL] and set to [10X]. The X in the 3rd digit means you must select the relevant channel for the input signal. Enter this mode and set the offset setting [OFF_1] to 0 and the scale setting [SCA_1] to the new scale factor.

Enter Calibration Mode
