Terminal assignment

Connection example for optionally switching output
Please note : The max. permitted voltage and switching current of the switching output must not be exceeded (even not for a short time).

Example assignment for switching output (i.e. switching of relays )

Configuration

Note : The device can be ESD sensitive at the area of the buttons. The configuration must be done considering adequate ESD safety measures!

Please note: measuring current should be at least 4 mA during configuration of a GIA 0420 N!

Follow these instructions to configure the device:

• Press button 2 for 2 seconds during actual value display, „dP“ is displayed.
• Set parameter value with button 2 and button 3.
• Save the set with button 1, the parameter name is displayed again.
• Proceed to the next parameter with button 1, the name of that parameter is dis- played.

If there is no key pressed within 60 seconds the configuration is cancelled. The settings already entered are lost.

Exceeding of the measuring range limit is tolerable as long as value is within measuring range (p.r.t. note).

ON.ER| active, (display error):

The measuring range limit is exactly bounded by the input signal.

When exceeding or short falling the input signal the device will display an error message.

ON.RG| active, (display measuring range limit):

The measuring range limit is exactly bounded by the input signal.

When exceeding or short-falling the input signal the device will display the se- lected lower/upper display value.

e.g. humidity: when shortfalling or exceeding, the device will display 0% or 100%.

_ _Note:_ When exceeding the measuring range, the device will always display an error message (.Err.1. or .Err.2.) independent of the current limit settings ._

The measuring range is from approx 3,7 and 20,8 mA respective 10.5 V (a falling below 0V will not detected) .

FILT| Filter
OFF| Filter deactivated
0. 1 … 2.0| Filter active:    Prevents “jumping” of the last digit and filters short noise pulses.

Higher numbers imply stronger filtering

Attention: this causes higher response times of the switching functions!

Offset and slope adjustment

Note : The device can be ESD-sensitive at the area of the buttons. The configuration must be done considering adequate ESD safety measures!
The offset and slope-adjustment function can be used for compensating the tolerance of the used sensor, resp. for vernier adjustment of the used transducer/transmitter.

Follow these instructions to run the offset and slope adjustment of the device:

• Press button 3 for 2 seconds during the actual value display, and „OFFS“ is displayed.
• Set parameter value with button 2 and button 3.
• Save the set with button 1, the parameter name is displayed again.
• Proceed to the next parameter with button 1, the name of that parameter is displayed.
  Parameter| Value| Description
  ---|---|---
  Button 1| Buttons 2 and 3|
  OFFS| Offset
  -5.00 … 5.00| The offset in digit

The set offset value is subtracted from measured value.

SCAL| Scale

-5.00 … 5.00

| The scale in %.

The displayed value is calculated according to the following formula:

Display = (measured value – offset – di.Lo) * (1 + slope adjustment [% / 100] ) + di.Lo

Example for offset and slope adjustment:

Connection of pressure transmitter.
The device displays without offset and slope adjustment: at 0 bar = 0.08, at 20 bar = 20.02

From this calculated:| offset:

slope:

| 0.08

20.02 – 0.08 = 19.94

---|---|---
difference :| 0.06| (= ideal slope – actual slope = 20.00 – 19.94)
Therefore this values should be set:| offset =| 0.08
scale =| 0.30| (= difference / actual slope = 0.06 / 19.94 = 0.0030 = 0.30% )

From this calculated: offset: 0.08 slope: 20.02 – 0.08 = 19.94 difference: 0.06 (= ideal slope – actual slope = 20.00 – 19.94)
Therefore this values should be set: offset = 0.08 scale = 0.30 (= difference / actual slope = 0.06 / 19.94 = 0.0030 = 0.30% )

Min -/max max- value memory

The device features a minimum/maximum-value storage. In this storage, the highest and lowest performance data is saved.

• Calling of the minimum value:
  Press button 3 shortly: the device will display “Lo“ briefly, after that the min-value is displayed for about 2 sec.

• Calling of the maximum value:
  Press button 2 shortly: the device will display “Hi“ briefly, after that, the max-value is displayed for about 2 sec.

• Erasing of the min/max values:
  Press buttons 2 and 3 for 2 sec.: The device will display “CLr“ briefly, after that the min/max values are set to the current displayed value.
