2. Introduction

The GIA 20 EB / PK is a microprocessor controlled displaying, monitoring and controlling device.

The device is supporting one universal interface for the connection of:

- Standard transmitter signals (0-20mA, 4-20mA, 0-50mV, 0-1V,

0-2V and 0-10V )

- Resistance sensors

- Frequency (TTL and switching contact)

The device features two switching outputs, which can be configured as 2-point-controller, 3-point-controller, 2-point-controller with min./max. alarm, common or individual min./max. alarm.

The state of the switching outputs is displayed with two LED’s beneath the front 4-digit LED-display.

The left LED displays the state of the 1st output, the right LED displays the state of the 2nd output. Furthermore the device supports one EASBus-interface so that the device can communicate with a host

computer via an interface converter and makes the device to a full functions EASBus-module. When leaving our factory the GIA20EB / PK has been subjected to various inspection tests and is completely

calibrated.

Before the GIA20EB / PK can be used, it has to be configured for the customer’s application.

Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we sug-

gest to connect the device’s switching outputs after You have configured the device properly.

For configuring the GIA20EB please proceed as follows:

3.3.6. Connecting a frequency- or rotation-signal

When measuring frequency or rotation three different input signals can be selected in the device’s configuration.

There is the possibility of connecting an active signal (= TTL, ...), a passive sensor-signal with NPN (= NPN-output, push-button, relay, ...) or PNP (= a PNP output switching to +Us, high-side push-button, ...).

When configuring the device with a NPN switching output, a pull-up-resistor (~11kΩ referring to +3.3V) is connected internally. So when You use a device with NPN output You don‘t need to connect a resistor externally.

When configuring the device with a PNP switching output, a pull-down resistor (~11kΩ referring to GND) is connected internally. So when You use a device with PNP output You don‘t need a resistor externally.

It may be that your measuring-signal source needs the connection of an external resistor e.g. the pull-upvoltage of 3.3V is not enough for the signal source, or you want to measure in the top level frequency range. In this case the input signal has to be treated like an active signal and you have to configure the device as „TTL“.

Hint: when connecting the device You have to take care not to exceed the limits of the input

voltage respective the input current of the frequency-input.

(Rv1 is a current limiting resistor and may be shorted if necessary. It should never exceed the mentioned value.)

3.3.7. Connecting a counter signal

When configuring the device you can select 3 different input signal modes similar to the connection of frequency- and rotation-signals. The connection of a sensor-signal for a counter-signal is the same used for the frequency- and rotation-signal. Please use the wiring diagram given in chapter 3.3.6.

There is the possibility to reset the counter. When connecting contact 8 with GND (e.g. contact 7) the counter will be reset. You can do this manually (e.g. with the help of a push-button) or automatically (with one switching output of the device).

Hint: When connecting the device, take care not to exceed the limits of the input-voltage or the input-

current of the frequency input.

3.4. Connecting switching outputs

The device features two switching outputs, with three different operating modes for each switching output, which are:

Low-Side: “GND-switching“ NPN output (open-collector)

The switching output is connected to the negative rail of the supply voltage (connection 3 or 5) when active (switching output on).

High-Side: “+Us-switching“ PNP output (open-collector)

The switching output is connected to the positive rail of the supply voltage (connection 4) when active (switching output on).

Push-Pull: The switching output is connected to the negative rail of the supply voltage (connection 3

or 5) when inactive. When the switching output is active, it’s connected to the positive rail of the supply voltage (connection 4).

In case of configuring one output as an alarm output, the output will be active in idle state (no alarm present). The output transistor opens or the push-pull output changes from +Us to –Us when an alarm condition occurred.

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.

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.) because of their high voltage peaks, protective measures to limit these peaks have to be taken.

When switching large capacitive loads a series resistor for current limitation needed, because of the high turn-on-current of high capacitive loads. The same applies to incandescent lamps, whose turn-on-current is also quite high due to their low cold resistance.

Hints:

Connections 3 and 5 are internally electrically connected.

When switching higher currents (> 50 mA) , the –Uv connection should not be attatched to the device (connection 3) but to the -Us connection of the external power supply unit.

When doing this, you get rid off ground displacement.

3.5. Common wiring of several devices

Inputs and outputs are not electrically isolated. When interconnecting several devices you have to make sure that there is no potential displacement.

Make sure to observe the following points:

- When several devices are connected to the same power supply unit it is highly recommended to isolate the sensors, measuring transducers etc.

- When the sensors, measuring transducers etc. are electrically connected, and you can’t manage to isolate them, you should use separate electrically isolated power supply units for each devices. Please note, that an electric connection may also be created via the medium to be measured (e.g. pH-electrodes and conductivity-electrodes in fluids).

- Press button 1 to validate your selection. The display shows “1.off“again.

Example: You want to control the temperature of a heating coil, with a hysteresis of +2°C, to 120°C.

Therefore you will have to select the turn-on-point “1.on“ to 120°C and the turn-off-point to “122°C“. When your heating coil temperature falls below 120°C it will be turned on. When the temperature rises above 122°C the heating coil will be turned off.

Note: Depending on the inertia of your heating coil an overshooting of the temperature may be possible.

5.2. 2-point-controller with alarm function

This chapter describes how to configure the device as a 2-point-controller with alarm function. This instruction demands that you selected “2P.AL as your desired output function like it is explained in chapter 4.8.

- Press button 1

- Use button 2 and button 3 to set the desired value, the device’s output 1 should be turning on.

- Press button 1 to validate your selection. The display shows “1.on“ again.

- When pressing button 1 again, the device will be displaying “1.off“. (turn-off-point of output 1)

- Use button 2 and button 3 to set the desired value, the device’s output 1 should be turning off.

- Press button 1 to validate your selection. The display shows “1.off“again.

Example: You want to control the temperature of a cooling chamber between –20°C and –22°C.

Therefore you will have to select –20°C for the turn-on-point 1 “1.on“ and –22°C for the turn-offpoint 1 “1.off“. When the temperature rises above –20°C the device turns its output 1 on, when falling below –22°C the device will turn its output 1 off .

Note: Depending on the inertia of your cooling circuit an overshooting of the temperature may be possible.

- When pressing button 1, the device will be displaying “AL.Hi“. (maximum alarm-value)

- Use button 2 and button 3 to set the desired value, the device should turn on its maximum-alarm.

- Press button 1 to validate your selection. The display shows “AL.Hi“ again.

- When pressing button 1 again, the device will be displaying “AL.Lo“. (minimum alarm-value)

- Use button 2 and button 3 to set the desired value, the device should turn on its minimum-alarm

- Press button 1 to validate your selection. The display shows “AL.Lo“ again.

- When pressing button 1 again, the device will be displaying “A.dEL“. (delay of the alarm-function)

(when not already done).

The device will be displaying “1.on“ (turn-on-point of output 1).

- Use button 2 and button 3 to set the desired delay of the alarm-function.

Note: The unit of the value to be set [0 .. 9999] is in seconds. The device will turn on the alarm after

the minimum or maximum alarm value was active for the delay-time you have set.

- Press button 1 to validate the delay time. The display shows “A.dEL“ again.

Example: You want to have an alarm monitoring for the cooling chamber mentioned above. The alarms

should start when the temperature will be rising above –15°C or falling below –30°C. Therefore you have to select –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 entered delay time.

Please note that the alarm-outputs are inverted! This means, that the output will be active when there is no alarm!

Now you finished configuring your device. Press button 1 to switch over to display the measuring value.
