Introduction
The Pleiger multi-function controller 362MC combines a large number of controller functions in a single
compact housing designed for installation in a control panel. A powerful microcontroller, a large parameter
memory and a two-line alphanumeric display support simple and swift operation and commissioning of the
controller.
The 362MC incorporates the following controller functions in one unit:
Two-point controller
Three-point controller with separate parameter sets for both outputs
Three-point step controller, with optional feedback of controller output
Continuous controller
Cascade step controller
Two independent control loops can be operated with one controller unit, provided that the controller is per-
missible for the application concerned.
The 362MC incorporates a large number of special features, such as:
an
actual-value display
and
manual controller output adjustment
which function
independently
of the microcontroller
to enable manual emergency operation for
switching controllers
, even in the event of processor failure;
a large non-volatile parameter memory to enable storage of up to 50 different controller
configurations for frequently required applications;
a two-line alphanumeric LCD display for process data and easily comprehensible operating
prompting;
a serial service interface which is accessible via the front panel of the controller, to enable
connection of a terminal or a PC to the Pleiger service programme 362McDiag.
In addition to the user-friendly operating and display functions, the 362MC does, of course, also provide
additional control functions to enable the safe and reliable control of complex systems, such as
differential trend compensation via the second measuring sensor, for enhanced control of
systems with large dead times;
switch-over to a second setpoint via an external signal;
inputs for an external setpoint and for logical adjustments and interlocks.
The 362 MC can be supplied in a configuration geared specifically to the application concerned, by means
of
different voltage variants
(230V-AC, 115V-AC),
different measurement ranges
(0-200°C, 0-500°C,
0-100%) and
different component variants
for the inputs (PT100, 4-20mA, 0-10V) and outputs (relays
with supply voltage or floating contacts).
Hardware extensions
are also available, such as
a 2
nd
relay group for switching outputs,
a module with 2 analogue outputs - 0(4)-20mA or 0-10V,
a module with RS 485/422 serial data interface
and
functional extensions
, such as
additive disturbance compensation weighted via any characteristic with five interpolation
points for advance compensation of the controlled system,
setpoint programmes for time-dependent setpoint adjustments and
difference input for actual values, e.g. for differential pressure control of pumps.
In the appropriate configuration, the single 362MC unit is thus able to replace the Pleiger controllers and
supplementary modules 361-D, 362-D, 366-D and 366-V.
