External Firing rate Input
You can establish an external firing rate input if control by atmospheric conditions is activated.
Therefore you must short-circuit terminals 25 and 26. Connect at terminals 16 and 17 a
0/4 ... 20 mA signal for setpoint presetting. Now you can adjust setpoint between a maximum
value at 0/4 mA and a minimum value at 20 mA. If you use setpoint switching, the range of
external setpoint switching is shifted.
External Setpoint Presetting
For the external setpoint values to be activated, parameter 40 must be set to the value 2 (con-
trol by atmospheric condition). The terminals 25, 26 and 27 must be short-circuited. At terminal
16 (-) and 17 (+) of the LCM100, a 0/4 ... 20 mA would be connected.
The following parameter must be set:
Lower limit for mode: ’controlled by atmospheric conditions’ in °C or digit.
This is the lower limit of the outside temperature at mode ’controlled by atmospheric
conditions’.
0 ... 249
0 ... 249 °C / 32 °F ... 480 °F
250 ... 500
-250 ... 0 °C / -418 °F ... 32 °F
475
-25 °C / -13 °F
Example:
Lower limit for mode: setpoint shift in 0,1 mA or digit.
This is the lower limit for the current input in 0,1 mA (min = 0; max = 500)
0 = 0.0 mA
40 = 4.0 mA
200 = 20.0 mA
