9.1.14.2 TERMINAL ASSIGNMENT
LCM100 has a 24V power supply for the pressure transmitter and
for the power supplies of other LSB modules.
The maximum current is 400mA for all power supplies.
This power supply is parallel to the 24V power supply of the LSB.
!
You are not allowed to feed the LSB terminal of LCM100 from
externally.

Analogue Output (Terminal 7; 8)
In this output, you could use the internal "analogue values" (e.g.
internal value for an external control system).
!
The cables must be schielded!
You can set different values for oil operation (P 0020) and gas
operation (P 0021) and the scale of output for oil operation (P 0024;
P 0028) and gas operation (P 0025; P 0029).
CAN Interface (Terminal 10 - 13)
We recommend you to use BT300 plug X31 for the connection
and prefabricated cable with LAMTEC Order No. 667P0515 for the
LCM100. The plug X31 is already installed on this cable and the
terminal numbers for the LCM100 are marked on the wires.
Power input L; N (Terminal 14; 15)
Connect the power input (90 - 250V 47 - 63Hz) to these terminals,
so that LCM100 can supply voltage to LSB (max. 400mA).
External regular firing rate input (Terminal 16 - 19)
