OVERVIEW

The Model IFMR continuously monitors the input signal and controls an output relay based on the frequency of the input signal, the chosen Operation Mode (Underspeed or Overspeed), and the Trip and Release points the user has selected. The green Input LED blinks at the rate of the input frequency. At about 100 Hz, the Input LED will appear to be solid on. At very low frequencies, the Input LED blinks slowly and may also appear to be solid on. A loss of signal may also cause the Input LED to remain on, depending on the DIP switch setup. In this case, the red Relay LED also turns on. The IFMR indicates the status of the relay with the Relay LED (Red). Whenever the relay is in the Trip state, the IFMR turns ON the Relay LED. In the Release state, the Relay LED is OFF.

For Overspeed detection, when the input frequency (averaged over the Minimum Response Time) exceeds the Trip point, the IFMR trips the relay. With the relay in the Trip condition, the input frequency must fall below the Release point for the relay to release.

For Underspeed detection, the relay trips when the input frequency (averaged over the Minimum Response Time) falls below the Trip point. The relay releases only after the input frequency has exceeded the Release point. Two of the Underspeed operating modes allow the machine or system that supplies the input signal to reach normal operating speed before the IFMR responds to an Underspeed condition. For Zero Speed applications, bear in mind that Zero Speed detection and Underspeed detection are identical.

The Minimum Response Time parameter sets the minimum update time of the output. The actual response time is the Minimum Response Time plus up to one full period of the input signal. The IFMR counts the negative edges occurring during the update time period, and computes the average frequency value for that time. This action filters out any high frequency jitter that may be present in the input signal. The longer the Minimum Response Time, the more filtering occurs.

The Offset value is added to the Trip Frequency to determine the Trip Point for Overspeed operation. For Underspeed operation the Trip point becomes the Trip Frequency minus the Offset value.

If No Hysteresis has been selected, the Trip and Release points are identical, which can lead to cycling or “chattering” of the relay at input frequencies hovering around the Trip point. If Hysteresis is selected, the Release point is set to the Trip point (including Offset) minus the Hysteresis value for Overspeed detection. For Underspeed detection, the Release point is set to the Trip point (including Offset) plus the Hysteresis value.

Two input pins (Alarm Override and Alarm Reset) are provided for the optional connection of push-buttons. The Alarm Override pin causes the IFMR to unconditionally Release the relay, regardless of the input frequency, or the state of the relay, when pulled to common. When the Alarm Override pin is released from common, the operation of the IFMR returns to normal, and the status of the relay is updated based on the input frequency.

The Alarm Reset pin is only active when the IFMR is in one of the Latch operation modes. With the Latch function selected, the relay “latches” into the Trip state whenever a Trip condition is detected. The relay remains latched until the Alarm Reset pin is pulled to common while the input frequency is in the Release region. The Alarm Reset pin is ignored while the input frequency is in the Trip region.

EMC INSTALLATION GUIDELINES

Although this unit is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into the unit may be different for various installations. The unit becomes more immune to EMI with fewer I/O connections. Cable length, routing, and shield termination are very important and can mean the difference between a successful installation or a troublesome installation.

Listed below are some EMC guidelines for successful installation in an industrial environment.

1.Use shielded (screened) cables for all Signal and Control inputs. The shield (screen) pigtail connection should be made as short as possible. The connection point for the shield depends somewhat upon the application.

Listed below are the recommended methods of connecting the shield, in order of their effectiveness.

a.Connect the shield only at the rail where the unit is mounted to earth ground (protective earth).

b.Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is above 1 MHz.

c.Connect the shield to common of the unit and leave the other end of the shield unconnected and insulated from earth ground.

2.Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run in metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter.

3.Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components.

4.In very electrically noisy environments, the use of external EMI suppression devices, such as ferrite suppression cores, is effective. Install them on Signal and Control cables as close to the unit as possible. Loop the cable through the core several times or use multiple cores on each cable for additional protection. Install line filters on the power input cable to the unit to suppress power line interference. Install them near the power entry point of the enclosure. The following EMI suppression devices (or equivalent) are recommended:

Ferrite Suppression Cores for signal and control cables: Fair-Rite # 0443167251 (RLC #FCOR0000) TDK # ZCAT3035-1330A

Steward #28B2029-0A0 Line Filters for input power cables:

Schaffner # FN610-1/07 (RLC #LFIL0000) Schaffner # FN670-1.8/07

Corcom #1VR3

Note: Reference manufacturer’s instructions when installing a line filter.

5.Long cable runs are more susceptible to EMI pickup than short cable runs. Therefore, keep cable runs as short as possible.

WIRING CONNECTIONS

All conductors should meet voltage and current ratings for each terminal. Also cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit (AC or DC) be protected by a fuse or circuit breaker.

POWER AND OUTPUT CONNECTIONS

AC Power

Primary power is connected to terminals 10 and 12 (labeled AC). For best results, the AC Power should be relatively “clean” and within the specified variation limits. Drawing power from heavily loaded circuits or from circuits that also power loads that cycle on and off, should be avoided.

DC Power

The DC power is connected to Terminals 10 and 12. The DC plus (+) is connected to Terminal 10 and the minus (-) is connected to Terminal 12. It is recommended that separate supplies be used for sensor power and unit power. Using the same supply for both will negate isolation between input and power.

Output Wiring

Terminals 1, 2, and 3 are used to connect to the relay output. Terminal 1 is the normally open contact. Terminal 3 is the normally closed contact, and Terminal 2 is the output relay common.
