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.
With this setting UI300 still displays set-point 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. set-
point value and actual value are not displayed in UI300.
Short-circuit terminal 22 with terminal 23 and terminal 24.
Select the type of firing rate presetting.
NOTE:
With software version 1.1.0.0 or higher the LCM switches au-
tomatically to DPS 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.
Scaling:
0V/4 mA
= 0 digit internal firing rate
10 V/20 mA = 999 digit internal firing rate
Connection external/manual regular firing rate input (termi-
nal 16 - 19)
NOTE:
if 0 ... 10 v input is used for the presetting of the firing rate
the sensor must be able to fuse the input of the lcm100 with
100 ma to 0.
8.1.13 DIP switch
You can configure settings of LCM100 by DIP switches.
Functions of DIP switches
