for the manual presetting of the burner firing rate

527 BT300 2-stage valve opening point from 1-stage to 2-stage 0–999
528 BT300 2-stage valve closing point from 2-stage to 1-stage 0–999
531 BT300 Load controller module output set point, which enables
shifting to 2-stage
200–999
532 BT300 Load controller module output set point, which enables
returning to 1-stage
200–999
0 = potentiometer
1 = Three-Point-Step (TPS)
2 = 4–20mA current loop signal
3 = 0-10V voltage input
To generate adequate hysteresis, parameter 531 value should be set to an approx. 50
digits bigger value than what the parameter 532 value is.
External guideline value
LCM connectors 25 and 26 are connected together. The 0/4..20 mA guideline value
signal is connected to the LCM connectors 16 and 17. In this control mode, there must
not be any conductor loops to connectors 22, 23, and 24.
In this control mode, LCM’s own PID controller is not in operation. Hence the start-
up and shutdown limits must be formed externally controlled to the start-up circuit
(BURNER ON, X10).
External set point value
LCM connectors 25, 26, and 27 are connected together. The 0/4..20 mA guideline
value signal is connected to the LCM connectors 16 and 17.
Param. no Description Factory setting
40 Load controller module operation mode (setpoint shift) 2
52 mA-signal minimum (0 or 4 mA) 0 or 40
53 mA-signal maximum (20 mA) 200
48 Set point value 1 minimum vs 0/4 mA for example 80
49 Set point value 1 maximum vs 20 mA for example 100
With the sample setting, the set point value can be chosen with the mA-signal to be
between 80–100. When necessary, set point value 2 and the external set point value
(LCM connectors 2–5) can be changed according to the same procedure.
The PC application (LSB-Remote) gives a possibility to wider load controller parameter
setting.
See burner control manufacturer’s instructions for use and setting
parameters.
Parameter evaluation
Capacity control does not cause variation in boiler temperature or pressure with
optimum PID parameters.
