5.3. Wiring the AKM345 Double Gradient Option
5.3.1. Background
The Double Gradient option allows for setting two separate winding simulations in the same
Winding Temperature Indicating Thermometer. The CT input is provided with two
independently adjustable potentiometers for determining the heater current. Switching
between the heater currents is performed external to the thermometer.
5.3.2. Wiring Recommendations
The potentiometers are wired to the 56 and 57 terminal block positions. The CT input is
wired to the 5-5 positions as shown.
•
To activate the 56 Gradient, jumper between the right 5-5 and 56 terminal block
position.
•
To activate the 57 Gradient, jumper between the right 5-5 and 57 terminal block
position.
An example of external switch wiring is shown below.
