DANGER!
Attention! Short-circuit danger and electrical shock!
An improper wiring connection could lead to a short-circuit, which may cause damages to the
connected devices or to an electrical shock.
Please ensure all connections on SELV have a safe separation from main voltage in
wiring and with connected devices!
8.1.15.2 Terminal Assignment
LCM100 has a 24 V power supply for pressure transmitter and for power supplies of other LSB
modules.
The maximum current is 400 mA for all power supplies.
This power supply is parallel to 24 V power supply of LSB.
CAUTION!
You are not allowed to supply LCM100 through LSB terminals from external.
Fuel Meter
Fuel meters with pulse outputs can be connected to terminals 3 and 4. Switch contacts as well
as voltage pulses up to 300 Hz can be processed.
When processing voltage pulses voltage < 8 V is processed as OFF and voltage >16 V is pro-
cessed as ON.
The cumulative fuel consumption can be readout and reset with the LSB Remote Software.
Parameters 70 to 82 contain the settings for fuel meters.
