Product Usage Instructions

3. Start Up

NOTE: In case of power failure, the controller
remembers the mode of operation and returns to this mode upon power
supply restart (unless the time set in the 48 Setup cell
expires).

3.1 Operating Panel

The operating panel includes:

RTC CLOCK/PROCESS TIME
NEGATIVE PRESSURE VALUE
KEY OF THE AUTOSTART MODE
KEY OF THE INFO MODE
KEY OF THE START MODE

3.4 Autostart Mode

The autostart mode is used to enter the START mode with a time
delay.

To set the autostart moment:

Setup – HMD
Activation after a predetermined number of hours and minutes
(F47 SETUP – HM)

To exit the AUTOSTART mode, press the AUTO/START key again. You
can transition directly from AUTOSTART to START mode by pressing
the START key when the controller is in START mode.

Frequently Asked Questions (FAQ)

Q: How do I edit the set parameters of the process?

A: To enter the mode of editing set parameters, press the
corresponding key. The mode is indicated by the pulsation of the
diode on the key EDIT. Use the keys for correction of parameters.
The parameter being edited will pulsate, and confirmation and
proceeding to the next editing field is done by the OK key.
Pressing EDIT repeatedly means exiting from the editing mode.

3. START UP
After the mains are connected the controller is automatically activated. After the welcoming words the device displays in turn: current hour and minute, measurement in channel 1 vacuum in %, set value of the rotational speed of the drum. Three horizontal lines indicate the lack or failure of a measuring element. Diodes on the keys signal the mode of the device (e.g. editing or autostart mode). Horizontal lines at the left side of the displayed measured value signal the governor’s mode: controlled output causes that the diode lights. Diodes on the keys indicate the controller’s mode. Possible modes of operation are: AUTOSTART, START, INFO and EDIT. In the STOP mode, when the START mode ended, the word ,,STOP” is displayed on the screen instead of an hour and minute.
NOTE: in the case of power failure the controller remembers the mode of operation and returns to this mode at the power supply restart. (unless the time set in the 48 Setup cell expires).

In order to enter the mode of editing the set parameters of the process the key should be pressed mode is indicated by pulsation of the diode on the key EDIT.

. Entering into the edit

Keys

are used for correction of parameters. Parameter being edited is pulsating, confirmation and proceeding

to the next editing field is done by the OK key. Consecutive pressing of the key EDIT means exit from the editing mode.

The set parameters are co:

– START mode duration (number of hours and minutes)

– Negative pressure set value

– Rotational speed set value

3.3 INFO MODE

Single pressing of the

causes the display of information in dependence of the controller’s mode of operation::

For the AUTOSTART mode Depending on the parameter in the 47 Setup cell: At selecting HMD hour, minute and twenty-four hours delay before the START mode commences, At selecting HM number of hours and minutes remaining to the START mode

Consecutive information, for all modes, are the same: · temperature measurement: the upper display shows the current temperature measurement in channel 1, the lower reads TE, · the upper display shows PSET, the middle one the negative pressure (set value), the lower display indicates the rotational speed of the drum, · current date: starting from the upper display – one can read the year, month and day, · current time: starting from the upper display – one can read hour, minute and second.

Proceeding into the next (previous) information can be done by keys should be pressed again.

. To exit the INFO mode the INFO key

3.4 AUTOSTART MODE The autostart mode is used for entering the START mode with a time delay.

User manual INDU 20 v1.6(19)EN

Pressing

causes transition to the parameters editing of this mode.

There are two possibilities of setting the moment of the controller AUTOSTART:

Activation at the predetermined hour and minute with the possibility of adding the twenty-four hour delay (F47

SETUP – HMD).

Activation after the predetermined number of hours and minutes (F47 SETUP – HM)

To exit the AUTOSTART mode the AUTO/START key should be pressed again.

There is also a possibility of a direct transition from the AUTOSTART into the START mode. Single pressing of the START key is needed.

3.5 START MODE When all set parameters are introduced (see: EDIT MODE CHANGING OF THE SET VALUES) the process can begin, which means

the controller should be in the START mode. Beginning and ending of the START mode is done by pressing the key:

.

For the typical settings of the controller, entering the START mode activates governors and the countdown of the process time starts.

The display shows the number of hours and minutes remaining to the end of the process.

The end of the process is indicated by the internal sound signal of the controller and by controlling of the relay output REL5 (unless it is declared in the SF81 Setup as the temperature governor). If the cell SF81 value is set to 2 relays REL4, REL5 work in the Left/Right turnover.

SF81 2 REL4 and REL5 carries out the functions, which illustrate the chart.
SF75 TL – time relay attach turnover LEFT (default = 10sek.) SF76 TR – time relay attach turnover RIGHT (default = 10sek.) SF77 Tp pause time (default = 20sek) Pressing the OK key switches off the sound signal.

4. FUNCTION OF RELAYS
REL 2: is responsible for the increase of the negative pressure and the pump controlling (governor: simple hysteresis). REL 3: is responsible for the decrease of the negative pressure (governor: reversed hysteresis). REL 4: controlled in the START mode. REL 5: temperature regulation or alarm event signaling.
5. GOVERNOR OF THE “TEMPERATURE APPROACH”

Parameters:
Tz set temperature value. Tza temperature of the governor activation; up to this temperature the output is controlled (heating). When this temperature is reached the governing algorithm starts.
Dout state at the digital output (high state corresponds to the heaters being ON).
6. SELECTION OF SETTINGS OF THE PID GOVERNOR
To obtain an access to the settings of the PID governor coupled with the particular measuring channel the MINUS key should be pressed and held and then the INFO key. If the temperature governor is selected on the relay (REL 5) the upper display shows the information that the governor can be adjusted the OK key should be pressed. The edition of the selected parameter is being done on the middle display (pulsating value). Increasing of the parameter’s value can be done by the PLUS key, while decreasing by the MINUS key. Proceeding to the next parameter and confirmation of changes is done by pressing OK. Exit from the edition mode – by pressing the EDIT key.
Regulation is being done on the bases of:
To sampling period, Pr amplification of the proportional element, Ti integration constant (doubling time), Td differential constant (advancing time), TS set temperature, Writing 0 value for the integrating or differentiating element causes its switching off. Due to that feature, it is possible to obtain the arbitrary governing algorithm.

8. ALARMS
Controller INDU 20 signals 11 alarm events: · Err1 Failure of the internal sensor of negative pressure, · Err2 Failure or lack of the measuring element in the channel 1 (temperature), · Err3 · Err4 Permissible MAX negative pressure exceeded, · Err5 Permissible MAX temperature exceeded, · Err6 · Err7 Permissible MIN negative pressure exceeded, · Err8 Permissible MIN temperature exceeded, · Err9 · Err10 Alarm from the control input 1, · Err11 Alarm from the control input 2.

keys.

The first step in an alarm activation is the setting of the time delay [seconds] in SETUP (cells 71..73) between an alarm event and the alarm activation. Then the activation of the selected alarms in SETUP (cells 60..70) should be done.
Alarms are signaled on the display by the word Err with the adequate number, by internal howler, and – when in Setup cell 81 the relay REL 5 is in the mode of alarm signaling – by controlling of its output.
Alarm should be confirmed by the OK key. If the cause of an alarm is not removed, the controller after the time delay of the alarm activation – will again signal the alarm.
