Pulse Output For Totalizer (Frequency Output) - Flow vision FC100 - CA User Manual

5 . 1 1 Pulse output for totalizer (frequency output)

The totalizer function of the FC100-CA has been expanded by the output of proportional quantity
pulses. The function can only be displayed by version FC100-CA-U1T4 ... (transistor outputs).
The proportional quantity pulses have been determined as follow:
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 not
exceed 10 Hz. The limits that can be displayed are determined by the flow velocity range and the
pipe diameter.
Potential setting range of the pulse output: 1 pulse per 0.1 ... 999.9 [liter], [m
Behaviour of the pulse output when the max . frequency is exceeded
The max. frequency being exceeded will not cause the measurement to stop but will rather cause
the 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 error
memory observing the following sequence:
Error No. 20, 30, 60, 40, 41.
Behaviour of the pulse output when the measurement is stopped
When the measurement is stopped (as caused by priority II error and calling the CONFIGURATION
menu), the pulses for the quantity already counted will be available. Thereafter the output of pulses
will 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 deleted
The content of the totalizer may be deleted by simultaneously pressing ▲ UP and ▼ DOWN
= ▲ + ▼ in the main menu.
