8.1.12 External/Manual Firing-rate Presetting (Terminals 16 - 19)
In order that LCM100 interprets the inputs as external firing rate presetting, LCM must be
activated by P 0040. Therefore set P0040 to value 1 or 2 or 3
2
.
With this setting UI300 still displays setpoint value and actual value of LCM100.With software
version 3.4.0.0(UI300) and 1.2.0.0 (LCM100) or higher P 0040 may be set to value 3. Setpoint
value and actual value are not displayed in UI300.
Short-circuit terminal 22 with terminal 23 and terminal 24.
Select the type of external regular firing rateinput via P 0065.
NOTICE
With software version 1.1.0.0 or higher the LCM switches automatically to TPS input if
P 0065 = 2 (4 ... 20 mA) and input current <2,1 mA.
An input current of more than 3 mA ends this switch over.

Fig. 8-9 Connection possibilities of external firing rate input
NOTICE
If 0 ... 10 V input is used for the presetting of the firing rate the sensor must be able to load the
input of the LCM100 with 100 A to 0.
This is valid up to SN 16170050 only.

If the control is only performed on the external load, it can be set to the value 3 as of
version 1.4.0.0 of the LCM P0040. This m
eans that neither the setpoint nor the actual
value are displayed in the UI300.
Scaling:
0 V/4 mA = 0 digit internal firing rate
10 V/20 mA = 999 digit internal firing rate
