A major advantage of the G428 is its wide ranging capabilities

and ease of configuration. The G428 offers 50% input zero and

span adjustablity within each of the fullscale input ranges.

Unless otherwise specified, the factory presets the Model G428

as follows:

Input: J-type

Range: 0 to 500°C

Output: 4 to 20mA

Burn Out: Upscale

The DC power input accepts any DC source between 9 and 30V;

typically a 12V or 24Vdc source is used. For other I/O ranges

refer to Tables 1 through 6 and reconfigure switches SW1 and

SW2 for the desired input type range and output.

Do not attempt to change any switch settings with power

applied. Severe damage will result!

1. Choose the desired temperature range from table 6, then use

table 1 and 2 to configure the switches, as described in the

following steps, for thermocouple type and range.

2. With DC power off, position input switches 1 and 2 on "SW2"

for the desired burnout detection mode.

3. Set positions 4 through 10 on "SW2" for the desired

thermocouple range and type.

4. Set positions 1 through 8 of output range switch "SW1" for the

desired output signal. (Table 4)

1. After configuring the dip switches, connect the input to a

calibrated thermocouple source. Connect the output to the

actual device load (or a load approximately equivalent to the

actual device load value) and apply power.

NOTE: To maximize thermal stability, final calibration should be

performed in the operation installation, allowing approximately 1

to 2 hours for warm up and thermal equilibrium of the system.

2. Set the calibrator to the desired minimum input and adjust the

zero potentiometer for the desired minimum output.

3. Set the calibrator to the desired maximum input and adjust the

span potentiometer for the desired maximum output.

4. Repeat steps 2 and 3, if necessary for best accuracy.
