Weidmuller G468 Ultra SlimPak User Manual

Major advantages of the G468 are its wide ranging capability and ease of configuration. The G468 has 15
input range switch settings. Trim potentiometers allow 50% input zero and span adjustablity within each of
the 15 full-scale, input ranges.
For example, the 200V switch setting in Table 1 configures the input for a 0 to 200Vac range. Since the
span can be contracted by 50%, this enables an input span as narrow as 100Vac of the range. This span
can be positioned anywhere within the 0-200Vac range with a zero offset as large as 50% of the full scale
range (e.g. 100 to 200Vac range).
Unless otherwise specified, the factory presets the Model G468 as follows:
Input Range: 0-500mVac
Output: 4-20mA
The DC power input accepts any DC source between 9 and 30V, typically a 12V or 24Vdc source is used.
Do not attempt to change any switch settings with power applied. Severe damage will result!
Refer to Tables 1 through 3 for the proper switch settings. With power disconnected, use the switches (9 &
10) on SW1 to select the input type (voltage or current), on SW2 to select the desired output ranges, and
(1-8) on SW1 to select the desired input range.
1. After configuring the DIP switches, connect the input to a calibrated AC source. Connect the output of the
actual device load (or a load approximately equivalent to the actual device load value) and apply power.
Refer to the Terminal Wiring Diagram.
NOTE: to maximize thermal stability, final calibration should be performed in the operating installation,
allowing approximately 1 to 2 hours for warm up and thermal equilibrium of the system.
2. Set the calibrator to the desired minimum and adjust the zero potentiometer for the desired minimum
output.
3. Set the calibrator to the desired maximum and adjust the span potentiometer for the desired maximum
output.
4. Repeat steps 2 and 3, if necessary for best accuracy.
