They work according to the period measurement principlewith subsequent computing of the reciprocal value (computer principle).The frequency is measured continuously. The number of cycles considered for one measurement depends onthe minimum measuring time (=Fix Time) and the level of the input frequency, respectively on the limits to entering the Machine Factor M = f/nx with f (Hz) = signal frequency of the speed transmitter at a determined machine speedxand n (rpm) = machine speedthe limits for the frequency relay and the measuring range for the frequency/current-converter can be entereddirectly in relation between the signal frequency (f ) of a speed sensor and the rotational speed (n) of a pole wheel isthe following.

9 F = n * p / 60withf = Frequency of the speed transmitter in Hzn = Rotational speed of the pole wheel in rpmp = Number of poles on the pole wheelConsequently for rotational speed measurement the machine factor M = of the rotational speed n, any frequency proportional physical quantity to be measured may be used inthe above the two limits on the frequency relay the switch-on point (= Limit high) and the switch-off point (= Limitlow) can be entered separately, thus allowing for the realisation of practically any hysteresis:With the binary input connected to 0V (=low) relay control parameter set B is active. With the binary input left open (=high) relay control parameter set A is : When selected; if the input frequency goes above the upper limit value (or below the lower limitvalue) the relay changes its state and will be held in this state unless it is reset, even if the input frequency latergoes below the upper (or above the lower) limit configuration of the Relay Control, (Selection of Actuator) allows the relay s hold function to beindependently selected for both parameter sets A and B -activate/de-activate > upper limit value or < lower limit valueThe relay is reset by momentarily opening and closing again of the binary input (if parameter set B isactivated) resp.

10 By momentarily closing and opening again of the binary input (if parameter set A is activated)for a time between .. the binary input is opened (resp. closed) for a time longer than s , the parameter set A (resp. B ) willgo active and the communicated values (also displayed on the PC) and the relay will go to the actual statecorresponding to the parameter set A (resp. B )The input of all measuring parameters is made by the user, the manufacturer or the supplier via a PC and theRS232 interface according to order parameters are stored independent of the power supply by an EEPROM .The green LED on the front only indicates whether the instrument is working correctly (LED bright) or is in error(LED dark).
