### Detailed Description

The IF05 is a frequency/RPM input module designed specifically f Leopard family range. The IF05 input module receiv es and conditions a frequency input via pin 1 and supplies the input to the me ter for further processing. Selectable on-board headers provide configuration settings allowing different sensor types to be selected along with high and low-pass filtering.

### Interface Configuration

### Examples

The following example diagrams show the various header settings and input connections required f or a range of input sensor type s.

Example 1 NPN Open-collector Output with Pr oximity Switch Figure 3 shows a 3-wire proximity switch taking +24 V excitation from the meter with an NPN open-collector signal output connec ted to the input module as frequency with no filter ing.

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.

Example 2 PNP Open-collector Output with Pr oximity Switch Figure 4 shows a 3-wire proximity switch taking +24 V excitation from the meter with a PNP open-collector signal output connect ed to the input module as frequency with no lo w-pass filtering.

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

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 a void 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.

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 o wn supply voltage.

Example 6 Pushbutton Switch Figure 8 shows a pushbutton switch. The low-pass filter header is set to 200 Hz to debounce mechanical contacts. The sensor header is set to SINK to pull-up the input signal to +24 V until it is switched to ground when the pushbutton is pressed.

Example 7 NAMUR Sensor Figure 9 shows a NAMUR 2-wire pro ximity detector. 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 v ary in response to the proximity of the target metal.

Setting Up IF05 for BL-40F and DL-40F Frequency

Meters

To set up the IF05 input module f or frequency input in a Leopard BL-40F or DL-40F frequency meter, carry out the following procedures:

Step 1

Establish the scale factor for the desired display reading

Maximum Display Range

Input Frequency

x Required Display Reading

= Scale Factor

Step 2

Set the new scale factor

Step 3

Select the range for the desired display reading

Step 4

Select the decimal point position

Frequency Meter

Calibrated

Step 1 Establish the Scale Factor Establish the scale f actor for the desired displa y reading. The default scale factor is 9999. If you want the scale f actor to be anything other than the input frequency or m ultiples of 10 of the input frequency, then a new scale factor must be established and set.

For example:

If we had an input frequency of 4 Hz and required a displa y reading of 400 counts, then the scale factor would not change from 9999.

But, if we had an input frequency of 4 Hz and required a displa y reading of 120 counts, then the scale f actor would be 2999. To establish a new scale factor, carry out the following calculation:

Maximum Display Range

(Default Scale Factor)

Input Frequency

Required Display Reading = Scale Factor

Example:

9999

x 120 = 2999

Step 2 Set the Ne w Scale Factor If the scale factor has to change, enter the meter calibration mode and set the new scale factor. See Figure 11 Calibration Logic Diagram.

Step 3 Select the Rang e for the Desired Display Reading The range multiplier and the decimal point position settings allo w you to set the the display resolution to suit the desired di splay reading. The range multiplier allows you to display the reading using either a x1, x10, or x100 range setting. For example, if you had a 4 Hz frequency input and wanted it to display as 400, you would choose the x100 range multiplier.

But, what if you had a 4 Hz input and wanted it to display as 120. First you would need to establish and set the new scale factor. Then you apply the same pr inciple as you would for 4 Hz to displa y 400 counts. 4 Hz is a single digit n umber and you require it to be displayed as 120 counts. 120 counts is a 3-digit number, so you effectively apply the x100 range multiplier, but because of the new scale factor, instead of displaying as 400 it is displa yed as 120.

Table 1 shows how to use the range multiplier for a range of frequency inputs where the scale factor has not been changed. If the scale factor is changed, the number of digits shown depends on the range multiplier chosen.

Note, the decimal point sho wn on the displa y at this point is not the setting f or the decimal point, but merely a means of displa ying the range multiplier setting.

Step 4 Select the Decimal P oint Position The decimal point can be set to one of three positions on the display or not displayed at all.

This allows you to display a 4-digit reading as a full number (xxxx), a 3-digit reading to one decimal place (xxx.x), a 2-digit reading to two decimal places (xx.xx), or a 1-digit reading to three decimal places (x.xxx).

To complete our e xample in Step 3 where an input frequency of 4 Hz displa counts, set the decimal point to the xxxx position. The display reads 120 at 4 Hz input.

Setting Up IF05 for BL40RPM and DL-40RPM

Meters

To set up the IF05 input module f or rpm input in a Leopard BL-40RPM or DL-40RPM meter, carry out the following procedures:

Step 1

Establish the pulses per revolution for the sensor

Step 2

Set the pulses per revolution (PPR) in the meter

Step 3

Select the display resolution

RPM Meter

Calibrated

Step 1 Establish the PPR for the Sensor The sensor has an output r ated in pulses per revolution (PPR). You will need this setting f or the next step.

Step 2 Set the PPR in the Meter Enter the meters PPR and range setting mode and set the pulses per revolution you require (PPR output of your sensor). See Figure

12 PPR & Range Setting Logic Diag ram.

Step 3 Set the Displa y Resolution After you have set the PPR setting, enter the range [rG] menu and select the resolution setting you require from one of the three ranges available.

Range Setting 0.1

This setting pro vides you with a resolution of 1 digit after the decimal point. For example, if y our PPR setting is 1, then y our display reading would be 1.0. If your PPR setting is 25, then y our display reading w ould be 25.0. The maximum PPR in this r ange is 999.9 rpm.

Range Setting 1

This setting provides you with a resolution of 1 to 1. For example, if your PPR setting is 1, then your display reading would be 1. If your PPR setting is 25, then y our display reading would be 25. The maximum PPR in this range is 9999 r pm.

Range Setting 1000

This setting provides you with a resolution of 2 digits after the decimal point. For example, if your PPR setting is 1, then y our display reading would be 1.00. If your PPR setting is 25, then y our display reading would be 25.00. The maximum PPR in this range is 99.99 rpm.
