Fast pulses

Note

CL module WZU-CL

Siemens
Building Technologies
Pulses for energy, volume, and tariff register
Period duration >200 ms
Pulse duration 100 ms conducting
Pulses for operating states
"Ready" pulsed "conducting", i.e. 0.1...0.25 ms pulse duration,
500 ms period
"Fault" constantly "non-conducting"
Applications, such as controllers or flow measuring sections, require higher pulse
rates. The parameters required for this purpose (pulse valency, pulse duration),
can be configured via the service software.
The maximum pulse frequency is 33 Hz.
When battery-powered, a D-cell is required!
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
o
Pulse duration, if 2 pulse modules are fitted:
From 5 ms to 100 ms in increments of 5 ms
o
A suitable device can be used to receive and evaluate the pulses. The settings
must be made in accordance with the controller's Data Sheet.
Linear pulses are output 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.
