MODEL IFMR - DIN-RAIL SPEED SWITCH
DESCRIPTION
The Model IFMR accepts a frequency input, and controls a single relay
(SPDT) based on the value of the input frequency. The Trip frequency can be
set to any value from 0.1 Hz to 25 KHz. The IFMR can be set to trip on
overspeed, or underspeed (including zero speed). Offset and hysteresis values
can be incorporated into the trip setting to eliminate output chatter. LED
indicators for both the Input signal and the Relay status are provided. Two
separate input connections for external push-buttons are also provided. One
external input overrides the trip detection function, and holds the relay in the
release state as long as the input is pulled to common. The other external input
clears a latched trip condition when pulled to common.
The IFMR utilizes a seven position DIP switch, a rotary switch, a push-
button and two indication LEDs to accomplish input circuit configuration,
operational parameter set-up, input signal, and relay status indication. The input
circuitry is DIP switch selectable for a variety of sources.
The indication LEDs are used during normal operation to display the input
signal and relay status of the IFMR. These LEDs are also used to provide visual
feedback to the user of the current parameter settings during parameter set-up.
The IFMR operates in one of six output modes, as selected by the user. The
programmable Minimum Response Time provides optimum response vs. input
filtering for any input frequency. The offset and hysteresis settings provide
flexible adjustment of the relay trip and release points.
The unit is equipped with a universal mounting foot for attachment to
standard DIN style mounting rails, including top hat profile rail according to EN
50 022 - 35 x 7.5 and 35 x 15, and G profile rail according to EN 50 035 - G32.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
WARNING: SPEED SWITCHES MUST NEVER BE USED AS
PRIMARY PROTECTION AGAINST HAZARDOUS OPERATING
CONDITIONS. Machinery must first be made safe by inherent design,
or the installation of guards, shields, or other devices to protect personnel in
the event of a hazardous machine speed condition. The speed switch may be
installed to help prevent the machine from entering the unsafe speed.
