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.

On power up, the

362MC always

displays the type and version no.

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.
