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.

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.

- 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

Addendum A: PID-control definition
Set point value:
The temperature on which the controlling shall be done.
Manipulating variable:
The power the controller passes on the process.
0 = 0% power; 1 = 100% power.
This is done at
PID-controller by clocking switching function 1 or the continuous output.
Motorised valve control: by switching “switching output 1“ and “switching output 2“.
output 1 = open actuator
output 2 = close actuator
„1.Pb“ (Proportional band):
Bandwidth around the set point value, where the proportional control responds linear.
A small proportional proportion has the effect that a little divergence from the set point value leads to a
big change of the heating power.
A big Proportional proportion has the effect, that the controller intervene weakly. The control gets inert.
„1.Int“ (Integral time, I-action):
Integral time [in sec.] of the PID control algorithms.
The higher the set value, the weaker the effect. The control tends to swinging if integral time is too low.
„1.dEr“ (Derivative time, D-action):
Derivative time [in sec.] of the PID control algorithms. The smaller the set value, the effect.
The derivative time reacts on the change of the manipulating variable.
„1.CyC“ (Cyclic time):
Cyclic time of the control [in sec.]. The control state is detected in the set cycle and the manipulating vari-
able is output accordingly.
At PID-control is this the cyclic time of output 1, too.
„1.dur“ (Propagation time of propulsion):
Time [in sec.] the propulsion needs to get the actuator from “entire close“ to “entire open“.
„1.thr“ (Minimum change of manipulating variable):
The minimum value of the manipulating variable in %, that must be reached, before there is an effect on
the output. By this parameter you can avoid that the actuator actuated too frequently or for a too short pe-
riod of time.

Addendum B: Tips for using the JDS-211 as heating controller
1. Set point value „1.SP“
The temperature on which the controlling shall be done. Please set here the desired temperature.
2. Proportional band „1.Pb“
The proportional band defines how strongly the device reacts on divergence between the actual and the set
point temperature . If the divergence equals the proportional band, the heating power is 100%. For a diver-
gence of 0°C the heating power is 0%.
Example 1: „1.Sp“=200.0, „1.Pb“=50.0
actual temperature=150°C !divergence=50°C !heating power=100%
actual temperature=180°C !divergence=20°C !heating power =40%
Example 2: „1.Sp“=200.0, „1.Pb“=100.0
actual temperature =150°C !divergence=50°C !heating power =50%
actual temperature =180°C !divergence=20°C !heating power =20%
A small proportional proportion has the effect that the device reacts to a little divergence with a big change of
the heating power.
If the proportional action is too small, there will be a over-reaction. The control gets instable.
!! Attention : A too small proportional band can lead too big excess temperature!!
A big Proportional proportion has the effect, that the controller intervene weakly. The control gets inert.
Tips for identification of the proportional band „1.Pb“.
Please set the following values by the configuration of your device:
Set point value “1.SP“: desired temperature
Proportional band “1.Pb“: 150.0
Integral time “1.Int“: 0 (off)
Derivative time “1.dEr“: 0 (off)
Cyclic time “1.CyC“: 2s (10s for inert control system)
Integral time „1.Int“ and derivative time „1.dEr“ are switched off. The device works as P-controller.
Start the control and wait until the temperature gets constant. This temperature , although much below the set point, has to be stable.
Now shorten the “1.Pb“ value, the divergence from the set point gets smaller. Go on with the scaling down until the temperature is not
stable any more, but oscillates continuously (about ±1°C). If the oscillation is too big re-raise the “1.Pb“ value a little bit.
Please consider the long settling time of some control systems you have to wait for.
Your “1.Pb“ value is the double of the value identified by that procedure.
3. Integral time „1.Int“
In chapter A.2 the device was a P-controller, who reacts only on divergences between actual and set point
temperature. Because there is no heating power at the divergence 0°, the actual temperature will always be
below the set point temperature. That changes with the configuration of the device as a PI-controller. The PI-
controller is additionally a integral controller, i.e. that it not only reacts on divergences, but considers also how
long this divergences have existed. The longer a divergence have existed, the bigger the heating power is. The
heating power changes while a divergence exists. Therefore even small divergences can be corrected in the
long run.
The strength of this effect is adjusted by the integral time „1.Int“. The device regulates the temperature quickly to
the set point temperature.
If “1.Int“ is too small, there will be a overshoot. The control gets instable and the temperature oscillates around
the set point.
!! Attention : A too small integral time “1.Int“ band can lead too big excess temperature!!
If 1.Int“ is too big, it may last very long until the device regulates the temperature to the set point.

Tips for identification of the integral time „1.Int“
Please set the following values by the configuration of your device:
Set point value “1.SP“: desired temperature
Proportional band “1.Pb“: value identified in chapter A.2
Integral time “1.Int“: 3600
Derivative time “1.dEr“: 0 (off)
Cyclic time “1.CyC“: 2s (10s for inert control system)
Derivative time “1.dEr“ is switched off. The device works as PI-controller. Start the control and wait until the
temperature gets to the set point. If this takes too much time shorten the value of “1.Int“. To avoid overshoots
please watch how fast the temperature rises. Is the rise too small, shorten “1.Int“ again. Is the rise already
very big, raise “1.Int“. If “1.Int“ is not too small the temperature should be stable at the set point.
Now there has to be an external interference on the control system (i.e. fill in cold water, put a cold object
onto the controlled metal block, etc.). This interference should be a quite realistic to that under operating
conditions. If no external interference can be carried out, you can also change the set point value.
Watch how the device regulates the temperature to the set point. If there is a overshoot the “1.Int” value has
to be raised. If the temperature approach the set point only very slowly the “1.Int” value can be shorten.
Please consider to wait the settling time (up to several minutes for some control systems) after each change
of “1.Int”.
Your “1.Int” value is 1.2 times the value identified by that procedure.
4. Derivative time „1.dEr“
If cold water is filled in a heated water tank the temperate falls rapidly. A human operator, who regulates the
temperature of the tank manually, will intuitively turn immediately the full heating power on, then cut it down to
approach the set point by small changes of the heating power.
The D-action (derivative action) of the PID-controller is responsible for the intervention at that big by big tem-
perature changes. The D-action doesn’t react on the divergence between actual and set point temperature, but
on temperature changes. If the temperature falls very quickly there will be a big heating power due to the D-
action. If the actual temperature approaches the set point very fast the D-action reduces the heating power
calculated by the P- and I-action. If there is no temperature change the D-action is zero.
The strength of this effect is adjusted by the derivative time “1.dEr“. A small “1.dEr“ value means, that there is
only a small reaction on temperature changes. A big one means, that there is a big reaction on changes.
In a lot of application the use of the device as a PI-controller is entirely satisfactory. In this case set the deriva-
tive time “1.dEr“ to 0.
If the PID-control is needed, “1.dEr“ has to be identified. This requires exact information about the controlled
process and knowledge of control engineering. However, a derivative time “1.dEr“=Integral time “1.Int”/5 has
delivered an optimal performance in practice.
Your “1.dEr“ value is 0.2 times the “1.Int“ value.
5. Cyclic time “1.CyC“
The device regulates the heating power by switching the existing heating on and off. If only 50% of the ex-
isting heating power are needed the heating is only half the time switched on. The frequency switching on
and off is adjusted by the cyclic time “1.CyC“.
Example: existing heating power 1000 W, 600 W heating power are needed
At a period time T=10s: the device switches the heating on for 6s and then off for 4s
At a period time T=200s: the device switches the heating on for 120s and then off for 80s
If the cyclic “1.CyC“ is too high the temperature of the heated object will get too high during the switch-on
period (although „1.SP“, „1.Int“, „1.dEr“ are correct) , only to cool down in the following switch-off period.
A very small “1.CyC“ value means that the relays switches a lot of times and that shortens the durability.
Therefore the cyclic time is ideally set to that value that is as high as possible, but where the effect during the
switch-on and –off periods is just not perceptible.
Tips for identification of the Cyclic time “1.CyC“:
Raise the cyclic time as long as the of the controlling deterioration is just not perceptible.
Your „1.CyC“ is 08. times the value identified by that procedure.
