GMBHFlow Meter | FC100-CAConfiguration5.11 Pulse output for totalizer (frequency output)The totalizer function of the FC100-CA has been expanded by the output of proportional quantitypulses. The function can only be displayed by version FC100-CA-U1T4 … (transistor outputs).The proportional quantity pulses have been determined as follow:1 pulse/quantity (totalizer unit selected)Example:1 pulse/10.0 [litre]The frequency output will supply 1 pulse per 10 litres (totalized quantity).When the quantity-proportional pulses are assigned, the frequency of the pulse output must notexceed 10 Hz. The limits that can be displayed are determined by the flow velocity range and thepipe diameter.Potential setting range of the pulse output: 1 pulse per 0.1 … 999.9 [liter], [m 3 ] …Behaviour of the pulse output when the max. frequency is exceededThe max. frequency being exceeded will not cause the measurement to stop but will rather causethe error output to signal error 60 on the display. This error is included in priority group III.If a combination of priority III errors occurs simultaneously, they are indicated or stored in the errormemory observing the following sequence:Error No. 20, 30, 60, 40, 41.Behaviour of the pulse output when the measurement is stoppedWhen the measurement is stopped (as caused by priority II error and calling the configurationmenu), the pulses for the quantity already counted will be available. Thereafter the output of pulseswill be stopped, with the pulse output becoming high resistive until the measurement is restarted.Behaviour of the pulse output when the content of the totalizer is deletedThe content of the totalizer may be deleted by simultaneously pressing UP and DOWN= + in the main menu.56
