Page 13: Chapter 1. Description
The first incoming pulse enables both the pulse counter and 5 MHz clock counter. The 2553 counts pulses and clocks until the clock counter is half full. On the next pulse input, the 2553 computes the frequency based on the number of 5 MHz clock pulses counted and the number of incoming pulses counted and outputs the value to the PLC. -
Page 14: N-Tooth Count Mode
1.2.2 N-Tooth Count Mode In N-Tooth count mode, the 2553 measures the amount of time of a full revolution of the wheel (based on the number of teeth entered in dip switch). The N-Tooth count mode is useful for compensating for errors introduced by wheel wobble (an effect that occurs when the wheel being measured is not perfectly round). -
Page 15: Overrange/Underrange Reporting
With no frequency input, the 2553 will report 0 in the data register (see Figure 2). The overrange/underrange bit (see Figure 3) will be set to 0. For frequencies under 76 Hz, the 2553 will report 0 in the data register (see Figure 2). The overrange/underrange bit (see Figure 5) will be set to 1. - Page 16 CT I 2553 Installation and O peration G uide...

The following sections discuss these important considerations. 2.2 Calculating the I/O Base Power Budget The 2553 requires 2.5 watts of +5V power from the I/O base. Use this figure to verify that the base power supply capacity is not exceeded. 2.3 Unpacking the Module Open the shipping carton and remove the special anti-static bag which contains the module. -
Page 18: Configuring The Module
I/O backplane. 2.4 Configuring the Module The Model 2553 must be configured to operate in normal counting mode or N-Tooth counting mode. The module must also be configured to report the measurements in "Frequency" or "Period" and digital filtering/no filtering mode before inserting the module into the I/O base. As shipped, the module is configured for normal counting mode, "Frequency"... -
Page 19: Selecting Normal Count Mode Or N-Tooth Count Mode
2.4.5 Selecting Input Signal Conditioning Each of the inputs of the Model 2553 may be configured to support bipolar, positive pulse, negative pulse or open collector applications. Jumpers JP5 for Channel 1 and JP7 for Channel 2 allow each channel to be independently configured. -
Page 20: Open Collector Conditioning
Each input channel may be driven by an external device with open collector output drive. Jumpers JP8 and JP9 are used to configure the input channels for open collector operation. Figure 8 Open Collector Selection CT I 2553 Installation and O peration G uide... -
Page 21: Standard Shipping Configuration
Figure 9 Open Collector External Device 2.4.7 Standard Shipping Configuration The Model 2553 is shipped from the factory with both channels configured for normal operation and with bipolar signal conditioning. WARNING: The module must not be inserted into the I/O rack while power is applied. -
Page 22: Wiring The Input Connectors
Avoid placing low voltage wire parallel to high energy wire (if the two wires must meet, cross them at a right angle). Avoid bending the wire into sharp angles. Use wireways for wire routing. Avoid placing wires on any vibrating surface. Figure 10 Input Connectors CT I 2553 Installation and O peration G uide... - Page 23 CT I 2553 Installation and O peration G uide...

Page 24: Connecting The Shield Wiring
2.6.1 Connecting the Shield Wiring Control Technology Inc. recommends that all wires be shielded twisted pair with a foil wrap shield and a separate drain wire and that they be installed in a metallic conduit. Use Belden cable 8761 or equivalent which contains a foil wrap shield and a separate drain wire. -
