1 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 2nd 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.

2 Display and operating elements
The 362MC controller incorporates a 2½-digit LED actual-value display for the 1st controller which is
clearly legible at a distance. For special applications, the display is also available as a 3½-digit variant
(with decimal digit or for special measuring ranges). The 362MC additionally features an two lines LCD
process data and parameter display. During normal operation of the controller, this display is employed to
display various process variables. The display also provides easily comprehensible operator prompting for
all entry operations.
Eight buttons are integrated in the foil of the front panel to control the display, to enter data, to switch the
operating mode and to activate emergency manual mode. The buttons are arranged in three groups.
A practical, replaceable labelling field is provided under the foil for identification of the measuring point.
After removing the front frame and
lifting the lower part of the foil, the
fuse for switching outputs and the
connector for the service interface
are also accessible after installation
of the controller. The labelling field is
simple to replace.

2.1 Display
On power up, the controller always displays the type and version no. first of all, before
switching to menu 1, the operational display. Here the process data are shown in the
two-line LCD display. Display lines 1 and 2 are visible in normal operating
mode. By pressing the Prgm button, the display can be switched to a
second mode (2nd line 1 and 2nd line 2)
for as long as the button is held.
The user can assign the process data
in the operational display to the lines via
the commissioning menu Display (5.8).
2.2 Operation
Operation of the controller, configuration and setting of the controller
parameters are carried out with operator prompting in 3 selection levels.
Menu selection constitutes the highest selection level. In normal
operating mode the menu selection remains hidden and the process
data are shown on the LCD display. The desired menu is selected via the
and buttons.
The menu name is now shown in the 1st line of the LCD display instead of the process data . Each menu
groups together entry items and parameters which are closely linked. The Prgm button can be used to
branch to the desired menu and the parameter selection function. The desired parameter is selected
here in the same manner, using the
and buttons.
The 1st line of the display shows the name and the 2nd line the value of the selected parameter. If the
selected value now requires to be altered, the Prgm button must be pressed to branch to the parameter
entry function. Here the value can
be altered with the
and buttons.
The value is entered and saved via
the Prgm button.
If the Exit button is pressed at any
point, the current selection will be
aborted. From the parameter entry
function the system will branch back
without altering the set value to
the parameter selection function,
from parameter selection the system
will always branch back to he menu
selection function, and from menu
selection menu 1 - the operational
display - will always be activated.
Should no button be pressed over a
period of 60 seconds during the
selection or entry process, the
operational display will be
re-activated automatically.

3 Operating modes
The 362MC incorporates two operating modes - Automatic and Manual / Emergency manual mode. A
modified menu is provided for each operating mode. Both operating modes offer an extended version of
the menu for commissioning purposes. This extension to the menus for configuration and
parameterisation of the controller is protected by a password to prevent unauthorised use.
3.1 Automatic mode
The green Auto LED lights up; the controllers are operating in a closed-loop system. The setpoints can
be altered via the setpoint entry or the commissioning menus can be activated via the menu selection
function, provided that the valid password has been entered.
3.1.1 Setpoint entry
After selecting the Setpoint Entry
menu under the menu selection
option in Automatic mode, the
setpoints and the alarm limits of
both controllers can be altered.
The 1st character of the name
displayed under the entry option
denotes the number of the controller - 1 or 2.
The letter A or B appears as the final character,
to distinguish between the main setpoint (A)
and the second setpoint (B) that becomes active
in the case of external setpoint switching.
The value for the lower alarm limit
of each controller is indicated by -
and the value for the upper alarm
limit is indicated by +.
See also Explanatory note on limit alarm (5.3.3).
This presentation of the setpoint entry procedure is based on the assumption that both controllers have
been configured as fixed setpoint controllers with setpoint type „fixed value“. The 1st controller setpoint is
101.0°C for Setp A and Setp B, irrespective of the setpoint switching function. 82.0°C is defined under
Setp A for the 2nd controller.
When external setpoint switching applies, Setp B is set at 65.0°C. When a different setpoint type is
configured, the setpoint entry display has a different appearance.
In the case of the setpoint type external setpoint (extern), an external value connected
at the input becomes the setpoint. It is thus not possible to alter this value by entering a
different value.
When the controller is implemented with a setpoint programme, the user
can switch between the stored programme numbers 1 to 5 (in this example 2).
See also Functional extensions (Appendix C3).

The buttons are provided only for the manual adjustment of switching
outputs on the 1st controller in Emergency manual mode, and have no other functions.
""
""
"
3.2 Switching between Manual/Automatic
Manual / Emergency Manual mode will only be activated if the user presses the Man and Exit button
simultaneously. This eliminates the possibility of Automatic mode being deactivated unintentionally or by
mistake. The green „AUTO“ LED turns off, and the text MANUAL is shown in the 1st line of the LCD display
in alternation with the process value. Manual operation of the outputs and emergency manual mode for the
switching output of the 1st controller are active.
Automatic mode is activated again by pressing the Auto button. The green LED marked „Auto“ lights up.
4 Manual / Emergency manual mode
When Manual / Emergency manual mode is active, buttons
-and +
are used to adjust the
1st controller´s switching output. When the +
button is pressed, the output is switched to +, as a result
of which the connected actuator is operated in OPEN direction. When the
-button is pressed, the
output is switched to -, as a result of which the actuator is operated in CLOSED direction.
This Emergency manual mode for the 1st controller operates irrespective of whether the micro-
controller is operational. The 2½-digit actual-value LED display of the 1st controller is also available for
Emergency manual mode independently of the microcontroller.
Manual mode is activated via the Manual menu to enable adjustment of a continuous controller output
of the 1st controller or to adjust a controller output of the 2nd controller. This menu can only be activated in
Manual mode, following the operational display.
Outputs are adjusted immediately. The percentage output value of a analogue output is altered from its
current value in accordance with the value entered by the user and is output directly. The switching output
on the 2nd controller is adjusted for as long as the button remains depressed.

5 Commissioning extension
The menu selection option of the 362MC can be extended for the purposes of commissioning the con-
troller. The extended functions for altering the configuration or parameterisation are available in both
Automatic and Manual / Emergency manual mode. The menu extension is accessible after entering the
password. This password lock serves to provide protection against unauthorised use.
5.0 Password entry
If no password has been entered (PW-lock=On), the password lock will be deactivated
to enable access to the extended commissioning menu by entering the currently valid password.
To this end, digits 1 to 4 have to be set to the stored
value for the password, in each case beginning from a
value of 0.
After input of the 4th digit, shown in the example here as password 1234, the value is compared against
the stored password. If the entered value corresponds to the stored password, the password lock will be
deactivated (PW-lock=Off); if the entered value does not correspond to the stored password, the pass-
word lock will remain active.
The password status is retained when the voltage supply for the controller is switched on and off.
On delivery, the password 0362 is stored for the 362MC.
Please alter this password to protect your specific settings.

5.3.1 Explanatory note on setpoints
The table for the Setpoint menu shows a permissible range from 0-200°C for setpoints “Setp A” and
“Setp B” of each controller. This range is valid for PT100 inputs in standard configuration. Additional
setpoint ranges can also be set, in each case adapted via the scaling factor to the employed measuring
sensors and the physical variables to be controlled.
These settings are carried out in the Input menu via parameters Scale-F, Scale-0 and Dim.
Several examples of other value ranges are shown in the following table.
See also Input menu (5.6)
5.3.2 Explanatory note on the switching filter
In order to avoid discontinuous transient conditions and overshoot
during setpoint switching, a switching low pass filter of the 2nd order
can be parameterised on the 362MC.
The time for the switching filter is set via the parameter Tf = T-Lowp.
5.3.3 Explanatory note on the limit value alarm
Alarm limits can be parameterised to monitor the actual values and
a permissible system deviation. These impose a lower alarm limit
and an upper alarm limit on the permissible control band. If the
actual value violates a fixed alarm limit for longer than 5s or a
relative alarm limit for longer than 60s, the alarm will be activated.
When an alarm is activated, the alarm relay is de-energised (Alarm ON)
(closed-circuit principle) and the current display is switched to the
error display. This display remains active until the alarm is
acknowledged via the Exit button. The alarm relay is energised
again (Alarm OFF) when the actual values is insite the control band.
For example:
Point 0: The 1st actual value attains the control band for the 1st time.
Alarm OFF; the alarm display function is started.
Point 1: The upper alarm limit is violated! The alarm is activated
(Alarm ON) and the error indication ActV++ is displayed.
Point 2: The upper alarm range is left again.
Alarm OFF; the alarm relay is energised.
Point 3: The lower alarm limit is violated. The alarm is activated
(Alarm ON) and the error indication ActV— is displayed.
Point 4: The lower alarm range is left again.
Alarm OFF; the alarm relay is energised.

5.4 Controller profile menu
On the 362MC, all the necessary settings for a controller are grouped together in
so-called profiles. Each profile thus contains all the parameters for a specific application.
The parameter memory of the 362MC contains 50 memory locations for different profiles, enabling
previously tested commissioning values to be stored as profiles for a large number of applications. The
commissioning procedure is then started by selecting the appropriate profile for the control task
concerned.
To this end, one of the controllers are first of all selected in the Profile menu via the parameter “DsplCtr”,
this controller´s profile is selected via “Prof-No” and its parameters are subsequently displayed and
altered in the following menus. Selection and entry points are marked accordingly on the display of the
362MC. The tables belonging to this description state which parameters are stored in which control menu.
5.4.1 Entering parameters for two controllers
It is to be noted here that
- only the parameters of one profile and thus of one controller are displayed;
- the two controllers must always be assigned different profiles via “Prof-No”.
During commissioning, the display should thus be set specifically to the controller which is to be put into
operation; e.g. from DsplCtr = 1 of 2 for the 1st controller to DsplCtr = 2 of 2 for the 2nd controller and
vice-versa. It is not necessary to enter the profile no. assigned to the controller under “Prof-No” again
for this purpose.
5.4.2 Entering parameters for one controller only
When the 362MC is used for one controller only, “DsplCtr” should be switched to “1 only”.
This precludes any switching. The parameters for the 2nd controller will no longer be displayed.
""
""
"If you save the selected profile to an available “Prof-No” via the “Save as” function
before commissioning, the parameters which have been altered in the course of
commissioning will be stored for you in this new profile. If possible, do not alter the
profile memory locations containing the factory presets, so as to ensure that you will
be able to access these profiles if necessary.
""
""
"With regard to the entry of parameters for the 2nd controller, the selection and entry
point is displayed as * to indicate controller 2 instead
of -> to indicate controller 1.

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 1st parameter set (1) and output-uses only the separate loop gain, Kr, and the parameters for
the switching outputs of the 2nd parameter set (2). See table:

This enables adaption of the 3-Point controller to two different actuators for outputs + and -. External pa-
rameter switching is not applicable here.
3-Point step controller = step controller for I-actuators with 3PntPW output
In conjunction with the down-line integrating actuator, the internal controller “Step” simulates a continu-
ous controller and has a 3-Point output with feedback. It is thus only suitable for use in combination with
integrating actuators, such as motor actuators.
(The operational characteristics of “Step” correspond to those of Pleiger controller 362-D)
Continuous controller = controller with continuous output.
The controller output of the continuous controller “Cont” is supplied to the assigned analogue output.
The required hardware configuration of the 362MC is to be observed.
(The operational characteristics of “Cont” correspond to those of Pleiger controller 361-D).
Cascade step controller = internal interconnection of 2 controllers to create the cascade controller
“CscStep”. Controller output Y1of the primary controller, with setpoint W and actual value X, is injected
into the secondary controller as setpoint V. In addition to the controlled setpoint V, the secondary 3-Point
step controller also receives secondary actual value U to form output Y2.
With setpoint gain KW2of the secondary controller can be employed, for example, to bypass the primary
controller during commissioning (Kr1=0 switches PID off, Kw2results in W=V).

When the cascade step controller “CscStep” is selected, the primary continuous controller always uses
the 1st parameter set (1) and the secondary 3-Point step controller uses the 2nd parameter set (2).
5.5.2 Explanatory note on controller structure
The parameterisable structures for the presented controller types are shown in the following table. On
selecting a controller type, the display always shows only the structures which are parameterisable in
accordance with this table!
P controller (proportional-action controller)
In the case of the P controller, a value of the controller output Y is
directly proportionally assigned to each value of the system deviation
xd. The assigned value is set via the gain factor Kr (P gain).
Xp is frequently used instead of Kr. Xp=100 / Kr
PI controller (proportional-plus-integral action controller)
In the case of the PI controller, the value of controller output Y is set
proportional to the system deviation xd (P component), and the
I component, which corresponds to the time integral of the system
deviation, is added to this value. The I component is set via reset time
Tn, which corresponds to the time in which the I component effects a
change in the controller output of a magnitude corresponding to the
P component.
PD controller (proportional-plus-differential action controller)
In the case of the PD controller, a D-component corresponding to the
time differential of the system deviation is added to the controller
output component (P component) which is proportional to system
deviation xd. The D component is set via derivative action time Tv,
which specifies how much earlier the step response of a PD controller
corresponds to a value which is attained by a P controller. A low pass
with the time constant T=Tv / Vd is employed to limit the bandwidth of
the differential element.
PD2 controller (proportional-plus-differential action controller)
This functions in the same manner as the PD controller, whereby the
D2 component corresponds not to the time differential of system
deviation xd but to the time differential of controlled variable X.
PID controller (PI controller with added D component)
PID2 controller (PI controller with added D2 component)
Regarding the D component, see also:
