ABB CoreSense M10 - Activating the Sensor Head Thermal Pump

Setting up the analyzer 7
Activating the sensor head thermal pump
This step should have been performed during system installation and commissioning, so this is mostly
a reminder of this critical procedure.
The CoreSense M10 sensor head is delivered with its thermal pump turned off. For configuration
purposes, the sensor head can be powered when it does not contain any transformer fluid.
However, its thermal pump must be turned off. When installation is complete and the sensor head is
in contact with transformer fluid, make sure to activate the thermal pump.
NOTICE
The thermal pump will fail within minutes if operated in air.
To activate the thermal pump:
1 From the CoreSense M10 dashboard (see Figure 2 on page 3), click Settings. The Settings page
appears (see Figure 3).
2 Click Administration settings and enter your password (for more information on passwords, see
“Changing passwords” on page 5).
3 Scroll down to the Application settings section and check the Enable thermal pump box.
When you check this box, a reminder appears, asking you to verify that the sensor head is properly
connected to the transformer (i.e., in contact with oil).
4 At the bottom of the page, click Apply to confirm activation of the thermal pump.
