Assembly

ATTENTION!

The Silicon washer should be lubricated by technical vaseline. Be aware that the washer should accurately adhere to the assembling surface.

ATTENTION!

Before connecting, verify the supply voltage on the device label. Depending on the version: 230V AC, 110-230V AC, 24V AC, 24V AC/DC

Startup

After connecting the temperature sensors (standard: PT-100) and power supply, the controller is switched on automatically. After displaying a “welcome” text the current hour, minute, channel 1 and channel 2 measurements are displayed consecutively.
When the display shows “—”, the controller indicates that a measuring element is missing or damaged.
Diodes located at keys indicate current status of the device (e.g. edit or auto start mode). Horizontal lines on the left side of displayed measured value indicate regulator status: diode on signals that an output is programmed. Key LEDS indicates the current operating mode. The following modes can be indicated: AUTOSTART, START, INFO, and EDIT.
In the STOP mode, after the START mode is completed, the display shows instead of hour and minute.

ATTENTION!

In case of power failure the controller saves in memory its current operating mode and when power is back, it returns to the same mode (unless time set in cell 48 — Setup has passed).

Operation description

EDIT mode – setpoint changing

To get into the setpoint edit mode press the EDIT key.
When the edit mode is activated, the EDIT key flashes.
You can change the parameters on the display by using the keyboard.
To confirm or move to the next field, press to exit press.

Setpoint sequence:

controller temperature setpoint based on channel 1
controller temperature setpoint based on channel 2

ATTENTION!

Channel 3 temperature setpoint can be entered in the SETUP menu (item SF38).

INFO mode

Press the key to recall information depending on the current controller operating mode.

For the AUTOSTART mode

According to the setting in the Setup menu, item SF47:
For HMD — hour, minute, and daily delay when the START mode is to be activated
For HM — hours and minutes to the START mode

Other information is identical for each mode:

channel 3 measurement (Ad-3), Measurement on channel 2; the calculated jacket temperature setpoint**
channel 1 and channel 2 temperature setpoints
current date
current time
To get the next (previous) information, press

AUTOSTART mode

Press the key to edit parameters for this mode.
AUTOSTART mode can be activated in two ways:

At a specified time (hour and minute) and daily delay, if any (F47 SETUP – HMD).
After counting down a specified time (hours and minutes) (F47 SETUP – HM)

Pressing the START button during edit mode causes the beginning of waiting mode for START (AUTOSTART). To quit the AUTOSTART mode,press the key once again. You can switch immediately from the AUTOSTART mode into the START mode by pressing the START key.

START mode

To start and end the START mode, press the key. For typical controller settings after switching into the START mode all regulators are activated and the process time counting down is started. The time in hours and minutes to the process end is shown on the display.
Depending on the SETUP configuration the following process end conditions may occur.
after process time elapsing (process timeout)
after the required bar temperature is reached
obtaining the required pasterisation number
The process end is indicated with an internal audible signal and by closing the REL5 Output To switch audible signal off, press.

Service functions accessible to the user

Cell no	Description
UF0	Real-time clock setting press for the next parameter

UF2	Information on software version
UF3	Keyboard click ON/OFF

To get into the user’s setting press and hold down the key and then press and hold down the key.
The functions mentioned above are available after the access code is entered. To disable the access code verification function, set the access code at 0000 for the user’s function. By default, the access code for service functions available to the user is disabled.

Alarms
The INDU 50 Controller recognizes 11 alarm events:

Err 1	Measuring element missing or damaged in channel 1
Err 2	Measuring element missing or damaged in channel 2
Err 3	Measuring element missing or damaged in channel 3
Err 4	MAX temperature exceeded in channel 1
Err 5	MAX temperature exceeded in channel 2
Err 6	MAX temperature exceeded in channel 3
Err 7	Temperature below MIN in channel 1
Err 8	Temperature below MIN in channel 2
Err 9	Temperature below MIN in channel 3
Err 10	Control input 1 alarm (depends on SF69 settings)
Err 11	Control input 2 alarm (depends on SF70 settings)

To activate alarms it is necessary first to set alarm activation time [seconds] in SETUP (items 71..73), and then enable the selected alarms in SETUP (items SF60..SF70). Any alarm shall be acknowledged by pressing. If the cause of the alarm has not been cleared, then the controller activates the alarm once again after the activation delay time.

Pasteurization

Due to the frequent application of the INDU50 controller as a unit controlling the process of thermal food processing, its properties were widened by the possibility of counting the pasteurization number according to the arithmetic variant of the general method.
The following sterilization coefficients were applied: (z = 4.8K; z = 7.78K; z = 10K; z = 15K; z = 25K; z = 33,34K — set in Setup; cell SF80) for the process temperature
Tr also set in Setup SF77. There is a possibility of performing the process either on the bases of the set value of the pasteurization number only (Setup SF76) or on the bases of the set value of the pasteurization number and the processing time. In the second case, the parametrization of maximum process time can constitute additional protection of the production process’s correctness. The setting of the adequate integration time, which means the time between consecutive moments of counting pasteurization number (setup cell SF79), was also taken into account in the INDU50 controller. The possibility of determining the temperature, from which the controller should start counting the pasteurization number (Setup SF81) was also added. In order to utilize the INDU50 controller for counting the pasteurization number the Setup cell SF45 – a condition of ending START mode – should be set on 19 or 20. The pasteurization number is determined in Setup SF76.

Governor diagrams

Governor – simple histeresis – heating Type 0*
Governor – reversed histeresis – refrigeration Type 1*
Tz – temperature setpoint t – time
Tz – temperature setpoint t – time
Governor – simple histeresis – algorithm of temperature approaching Type 2*
Temperature control can be divided into three zones. In the first zone the output Dout is controlled until Tza temperature is reached. Above the Tza temperature, in the second zone, the algorithm of temperature approaching the set value id realized. In the third zone the temperature in between the lower and upper histeresis is kept.
Governor of temperature approaching
Tz – temperature setpoint t – time Tza – thershold tempereature for triggering the „approach” algorithm (for temp. below Tza-Dout output is permanently on) Dout – state at binary output (high state corresponds with the activation of heaters)
Governor PID Type 3*
Tz – temperature setpoint t – time

Governor relative Type 4

Governor dedicated for jacket temperature control in parboilers. Jacket temperature control is carried out on the basis of the relationship between the preset and the read-out water temperature.

ATTENTION!

This type of governor is only available on channel 3 (cell setting SF31); controller configuration parameters: SF87,103, SF104, SF105.

Selection of governor setup PID

To obtain access to the governor setup PID coupled with the given measuring channel the key should be pressed and held and then the key. Information concerning the given parameter and the governor number will appear on the upper display.
Edition of the selected parameter is done on the middle display (pulsating value). Increase of parameter Value by the key, decrease by the key. Shift to the next parameter and confirmation of changes by the key. Exit from edition mode by pressing the key.

Regulation is being done on the basis of:

To – sampling period
Pr – strengthening of a proportional element
Ti – integration constant (doubling time)
Td – differentiation constant (advancing time)
Ts – set temperature

The most frequently asked questions (FAQ)

1. What to do when the governor does not switch on?

· Check the power supply of the governor.

2. The governor does not record the data after the end of the process.

· Check the setting of the SF46 cell. If continuous recording is required,

· which means recording regardless of the operation mode, write 0.

3. Is it possible to ommit the access code to service functions accessible for the user?

· Write 0 (zero) as the access code of the governor.

4. Transmission in RS485 network does not operate.

· Check addresses in RS485 network. Attention! Each device must have an individual address.

· The problem may also be: – incorrectly set baud rate in the governor, swapped A and B signals, damaged transmission line, and many others.

5. Temperature sensor PT-100, PT-500 or PT-1000 does not operate.

· Check the setting correctness for the temperature sensor, e.g. for the first sensor, PT-100, value 1 should be set in cell SF2.
