4. Start up
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).

6. Operation description
6.1. 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 parameters on the display by using the keyboard .
To confirm or move to the next field, press to exit press .
Setpoint sequence:
START mode duration (hours: minutes)
controller temperature setpoint based on channel 1
controller temperature setpoint based on channel 2
6.2. INFO mode
Press the key to recal 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
* when governor type 4 is set for channel 3
**when the pasterisation number is being counted
ATTENTION!
Channel 3 temperature setpoint can be entered in the SETUP menu (item SF38).

6.3. AUTOSTART mode
Press the key to edit parameters for this mode.
AUTOSTART mode can be activated in two ways:
1. At specified time (hour and minute) and daily delay, if any (F47 SETUP –HMD).
2. After counting down a specified time (hours and minutes) (F47 SETUP - HM)
Pressing START button during edit mode couses begining 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.
6.4. START mode
To start and end the START mode, press 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. .

function, set access code at 0000 for the user’s function. By default, the access code for service functions available to the
user is disabled.
6.6. 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 alarm has
not been cleared, then the controller activates the alarm once again after activation delay time.

7. Pasterisation
Due to frequent application of INDU50 controller as a unit controlling the process of thermal food processing, its properties
were widened by the possibility of counting the pasterisation number according to the aritmetric variant of the general
method.
The following sterilisation 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 pasterisation number only (Setup SF76), or on the bases of the set value of pasterisation
number and the process time. In the second case the parametrisation of maximum process time can constitute additional
protection of the production process correctness. Setting of the adequate integration time, which means the time between
consecutive moments of counting pasterisation number (setup cell SF79), was also taken into account in INDU50 controller.
The possibility of determining the temperature, from which the controller should start counting the pasterisation number
(Setup SF81) was also added. In order to utilise INDU50 controller for counting the pasterisation number the Setup cell SF45
–condition of ending START mode - should be set on 19 or 20. The pasterisation number is determined in Setup SF76.
