Pulse for operating states
"Ready" Pulsed "conducting", i.e. 0.1…0.25 ms pulse duration,
500 ms period
"Fault" Constant "non-conducting"
Fast pulses
Applications, such as controllers or flow measuring sections, require higher pulse rates. The
service software configures the parameters required for this purpose (pulse valency, pulse
duration).
The maximum pulse frequency is 33 Hz.
NOTICE
When battery-powered, a D-cell is required!
The following can be set:
● Pulse type: "linear" or "scaled" pulses
● Pulse output: Energy or volume
● Pulse duration, if only 1 pulse module is fitted:
– From 2 ms to 100 ms in increments of 1 ms
● Pulse duration, if 2 pulse modules are fitted:
– From 5 ms to 100 ms in increments of 5 ms
A suitable device can be used to receive and evaluate the pulses. Enter the settings in
accordance with the controller’s data sheet.
Linear pulses are outputted proportionally to the measured value. In the case of scaled
pulses, the number of pulses at the upper and lower end of the range can be defined. In this
case, the pulse receiving device can detect a wiring error, for example.
