A method of assigning an identifier to a controller of a modular vacuum pumping and/or abatement system, the method including: determining, by a first controller of the modular vacuum pumping and/or abatement system, that a first identifier is to be assigned to a second controller of the modular vacuum pumping and/or abatement system, wherein the second controller is located at a module of the modular vacuum pumping and/or abatement system; transmitting, by the first controller, a first signal indicative of the first identifier to the second controller; receiving, by a user input device coupled to the module, a user input; and adopting, by the second controller, the first identifier as its identifier in response to the user input.

Infra-red sensors are often used in turbo molecular pumps to detect the temperature of the rotor or other mechanical parts and therefore indicate imminent, or potential, running failures. As deposits build up on either the infra-red sensor, or on the surface being monitored, the reading given by the sensor may not be a true representation of the actual surface temperature which can cause the pump controller to fail to stop the pump in time. The present invention provides a method and device for calibrating the sensor by creating a determined temperature rise in the sensor whilst keeping the rotor at ambient temperature. In particular the present invention uses the motor stator as the heater for causing the temperature increase.
