GREISINGER GIR200 PT100 (01) PDF Document

To exclude risk for the operator, the following points must be observed:

a) Immediately switch off the device in case of visible damage or obvious malfunctions.

b) Make it a rule to always disconnect voltage source and device before opening it up. The entire device and its connection have to be protected against touching electrical contacts after installation.

c) Standard regulations for operation and safety for electrical, light and heavy current equipment have to be observed, with attention having to be paid to national safety regulations (e.g. VDE 0100).

d) When connecting the GREISINGER GIR200 PT100 to other devices (e.g. PC) the interconnection has to be designed most thoroughly as internal connections in third-party devices (e.g. connection GND with protective earth) may lead to undesired voltage potentials.

Skilled personnel are persons familiar with installation, connection, commissioning and operation of the product and have a professional qualification relating to their job. For example:

Training or instruction and qualification to switch on/off, isolate, ground and mark electric circuits and devices/systems.

Training or instruction according to the state of the art of safety technology to maintain and operate adequate safety equipment.

First-aid training.

All connections for the GREISINGER GIR200 PT100 are located at the back side of the device. Connections are made via screw-type/plug-in terminals.

Make it a rule to mount screw-type/plug-in terminals while they are still loose and to put them on only afterwards. When mounting terminals already put on there is a risk that soldering eyelets may be pulled out.

Please use a suitable screw driver and do not tighten screws by force.

Supply voltage: 230V AC, 50/60Hz or instructions on device. Please make sure that the mains voltage applied corresponds to the supply voltage stated at the device nameplate.

Switching output: 1 volt-free relay (changeover contact). Switching capacity: 10A, 250V AC (ohmic load).

When using inductive loads the contact has to be connected to a suitable RC-element (for example ‘RC220’).

The Pt100 sensor should be connected to the GREISINGER GIR200 PT100 by means of 4-wire technology as, then, line resistances (even if unsymmetrical) will not influence the measuring accuracy.

If 4-wire connection is not possible, the Pt100 sensor can also be connected to the device by means of 2- or 3-wire technology. Long connecting lines may lead to a wrong (too high) temperature display (fault depending on line resistance). In such a case, it is recommended to compensate for the fault by setting an offset value.

Connection Schematics:

4-wire connection: Connect wires to terminals 10, 11, 12, and 13.

3-wire connection: Connect wires to terminals 10, 11, and 12. Bridge terminals 12 and 13.

2-wire connection: Connect wires to terminals 11 and 12. Bridge terminals 10 and 11. Bridge terminals 12 and 13.

As soon as the supply voltage has been applied, the GREISINGER GIR200 PT100 will carry out a system test for approx. 8s. Then the current measuring value will be displayed, if a temperature probe is connected.

LED 1 gives the status of relay 1 (LED illuminated: relay contact made).

To be called up by: Pressing button 1 till LEDs “SET”, “1” and “ON/SP” are illuminated.

Display: The display shows the making point for switching output 1.

Setting: Set making point/switching point by means of buttons 2 and 3. LEDs “1” and “ON/SP” will start flashing.

Buttons 2 and 3 are equipped with a scrolling function. The making point will be increased or decreased by 1 digit when button 2 or button 3 is pressed briefly (no more than 1 s). When pressing these buttons for a longer time (over 1 s), the values will start “scrolling” upwards or downwards. After “scrolling” of approx. 150 digits, the “scrolling speed” will be increased by a factor of 10.

Use button 4 to acknowledge the new making point. LEDs “1” and “ON/SP” will stop flashing.

Switch over to display of current measuring value by pressing button 4 once again.

To be called up by: Pressing button 1 till LEDs “SET”, “1” and “OFF/Hy” are illuminated.

Display: The display shows the breaking point for switching output 1.

Setting: Set breaking point by means of buttons 2 and 3. LEDs “1” and “OFF/Hy” will start flashing.

Buttons 2 and 3 are equipped with a scrolling function. The breaking point will be increased or decreased by 1 digit when button 2 or button 3 is pressed briefly (no more than 1 s). When pressing these buttons for a longer time (over 1 s), the values will start “scrolling” upwards or downwards. After “scrolling” of approx. 150 digits, the “scrolling speed” will be increased by a factor of 10.

Use button 4 to acknowledge the new breaking point. LEDs “1” and “OFF/Hy” will stop flashing.

Switch over to display of current measuring value by pressing button 4 once again.

For some applications, a zero point offset (offset) has to be carried out (e.g., for compensation of line resistance when using 2- or 3-wire technology for connection). Proceed as follows:

1. Press button 1 (front side). Additionally press the miniature push button on the back side of the GREISINGER GIR200 PT100 (located behind the sensor connection terminal) for approx. 1s till LED “CAL” (on front side) is illuminated.

2. LEDs “Scale”, “OFF/Hy” and LED “CAL” are illuminated. The display will show the offset value stored in the device (zero point offset).

3. Use buttons 2 and 3 to set new offset (LED “OFF/Hy” will start flashing) and acknowledge by pressing button 4.

Example: If device displays 0.3°C instead of 0.0°C because of long probe connecting cables, an offset value of 0.3 will compensate for this deviation, and the display will be 0.0°C.

Note: The value entered will influence the values displayed on the device. As a standard, the offset value set should be 0.0.

FE 1: Measuring range has been exceeded

This fault code indicates that the measuring range of the GREISINGER GIR200 PT100 has been exceeded.

Possible fault cause:

temperature to be measured exceeds 199.9°C

sensor damage

sensor connection interrupted

Remedies: FE 1 will be reset as soon as the measuring values are back within their permissible range. Please check your Pt100 sensor and sensor connecting cables.

FE 2: Measuring values have fallen below permissible range

This fault code indicates that the measuring values of the GREISINGER GIR200 PT100 have fallen below the permissible range.

Possible fault cause:

temperature to be measured lower than -50.0°C

sensor damage

interruption/short-circuit in sensor connection

Remedies: FE 2 will be reset as soon as the measuring values are back within their permissible range. Please check your Pt100 sensor and sensor connecting cables.
