5.5.1 Explanatory note on controller types
The controller type “CtrlTyp” can be defined separately for each of the 362MC´s two controllers.
2-Point controller = switching controller with 2 switching output states, relay+ ON and relay+ OFF.
The 2-Point controller with feedback “2PntPW” operates internally as a continuous controller with
down-line pulse-width modulator and switching output. Its output corresponds to the ratio of ON period
to OFF period of relay+ of assigned relay set 1 or 2.
In the case of the 2-Point controller without feedback “2Point” the pulse-width modulator is replaced by
a threshold switch with hysteresis.
3-Point controller = switching controller with 3 switching output states, relay+ ON, relay+ and relay OFF
and relay- ON. The 3-Point controller with feedback “3PntPW” operates internally as a continuous
controller with two down-line pulse-width modulators and two switching outputs. Its output corresponds
to the ratio of ON period to OFF period of relay+ if the controller output is positive and relay- if negative,
both relay+ and relay- being from assigned relay set 1 or 2.
In the case of the 3-Point controller without feedback “3Point” the pulse-width modulator is replaced by
a threshold switch with hysteresis.
The two switching outputs can be parameterised separately, whereby the controller and output+ use the
complete 1
st
parameter set (
1
) and output- uses only the separate loop gain, Kr, and the parameters for
the switching outputs of the 2
nd
parameter set (
2
). See table:
