2. Introduction
The JDS-211 is a microprocessor controlled displaying,
monitoring and controlling device.
The devices supports an interface for the connection of Pt100
temperature probes.
Additionally the JDS 211 features two switching outputs.
The state of the switching outputs (relays) is displayed with the
LED’s “1” and “2”.
Furthermore all devices supports a serial interface for communicating with a host computer.
When leaving our factory the JDS-211 has been subjected to various inspection tests and is completely cali-
brated.
Before the JDS-211 can be used, it has to be configured for the customer’s applica-
tion.
Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we
suggest to connect the device’s switching outputs after You have configured the device
properly.
Hint: By calling a configuration menu for the offset- and slope-adjustment the measurement and
regulation of the device will be deactivated.
By leaving the menu the device will be reinitialised and the measuring/regulation will be
started again.
3. Electric Connection
Wiring and commissioning of the device must be carried out by skilled personnel only.
In case of wrong wiring the device may be destroyed. We can not assume any warranty in case of
wrong wiring of the device.

3.3. Probe connection
Please take care not to exceed the limitations of the inputs when connecting the device as this may lead
to the destruction of the device.
Note: The Pt100 probe should be connected as 3-wire system, because there the resistivity is mostly
compensated. 4-wire probes should be connected as 3-wire system, too. If a 2-wire system is essential,
the potential deviation can be compensated by the offset adjustment (chapter 5.2).

3.4. Connecting switching outputs
Hint: In order to avoid unwanted or wrong switching processes we suggest to connect the
device’s switching outputs after you have configured the device’s switching outputs
properly.
The device features two switching outputs (relays) by default.
Please take care that you must not exceed the limits of the voltage and of the maximum current
of the switching outputs (not even for a short period of time). Please take extreme care when
switching inductive loads (like coils or relays, etc.). Their high voltage peaks have to be limited
by adequate protective measures (e.g. RC-element).
Note: In case of configuring one output as an alarm output, the output will be active in idle state (no
alarm present). The output relay opens when an alarm condition occurred.

4. General notes to the operating of the menu
By means of button 1 you can go to the next parameter.
Additionally a given changing in the parameter setting can be con-
firmed by this button and the new value will be saved. Afterwards it
will be changed to the parameter view again
By means of button 2 or button 3 you can go from the parameter
view to the parameter setting and adjust its value there.
Hint: The buttons 2 and 3 are featured with a ‘roll-function‘. When pressing the button once the value will be raised
(button 2) by one or lowered (button 3) by one. When holding the button pressed for longer than 1 sec. the
value starts counting up or down, the counting speed will be raised after a short period of time.
The device also features a ‘overflow-function‘, when reaching the upper limit of the range, the device switches
to the lower limit, vice versa.
By means of button 4 a given changing will be cancelled in the parameter setting. The changing will be
discarded and the former parameter value will be preserved.
In the parameter view button 4 closes the menu.
Please note: If you don’t press any button for more than 10 sec. in the parameter setting, the adjustment will
be cancelled, the changing discarded and it will be changed to the parameter view. If you don’t
press any button for more than 60 sec. in the menu, the menu will be automatically closed.

5.2. Offset- and slope-adjustment: Menu calling and adjustment
- Turn on the device and wait after it finished its built-in segment test.
- At the same time press the pushbutton on the rear side (button 5) and button 3 for >2 seconds. The
device displays “OFFS“ (offset).
- Use button 2 or button 3 for setting the desired zero point offset-value.
The input of the offset will be in digit or °C.
The value that had been set will be subtracted from the measured value.. (for further information see “scale”)
- Press button 1 to validate your selection. The display shows “OFFS“ again.
- When pressing button 1 again, the device will be displaying “SCAL“. (scale = slope)
- Use button 2 or button 3 to select the desired slope-adjustment.
The slope adjustment will be entered in %. The displayed value is calculated depending on the input sig-
nal according to the following formula.
Displayed value = (measured value – zero point offset) * (1 + slope adjustment [% / 100])
Example: The setting is 2.00 => the slope has risen 2.00% => slope = 102%.
When measuring a value of 1000 (without slope-adjustment) the device would display 102 (with slope
adjustment of 102%)
- Press button 1 to validate the selection of the slope-adjustment. The display shows “SCAL“ again.
- When pressing button 1 again, the display shows “OFFS“ again.
Now you have finished the offset- and slope-adjustment.

E32.0.A3.6C-01 Manual for connection and operation of the JDS-211 page 9 of 16
- Press now button 4 to exit the offset- and slope-adjustment menu.
Example for offset- and slope-adjustment:
The device displays the following values (without offset- or slope-adjustment): 2°C at 0°C and 102°C at 100°C
Therefore you calculated: zero point: 2
slope: 102 – 2 = 100 (deviation = 0)
You have to set: offset = 2 (= zero point-deviation)
scale = 0.00
6. Operation

possible settings: 0 .. 9999
Example: You want to have a temperature alarm-monitoring of a cold room. The alarm should start when
the temperature rises above -15°C or falls below -30°C. Therefore your settings will be -15°C for
the maximum alarm-value “AL.HI“ and -30°C for the minimum alarm-value “AL.Lo“.
=> The alarm will be starting after the temperature rises above -15°C and stays above -15°C for
the entered delay time or after it had been falling below -30°C and stays below -30°C for the en-
tered delay time.
Please note that the alarm-outputs are inverted! This means, that the output will be active when
there is no alarm!
