Abstract: A testing method for a fan module is provided. When the fan module is tested, a testing computer sends a testing command to a testing device first. Then, the testing device responds to the testing command and controls the fan module to work in a plurality of rotational speed modes in sequence. The testing device reads an actual rotational speed when the fan module works in one of the rotational speed modes and sends the actual rotational speed back to the testing computer. The testing computer compares the actual rotational speed with a corresponding reference rotational speed value stored in the testing computer, and determines the testing result. Finally, the testing result is shown.

Abstract: The invention relates to a method for detecting a rotating stall fault in a compressor (12) which is driven by means of a three-phase current motor (8) fed by an inverter. According to the invention, an instantaneous estimated value (^m) which is calculated from measured power converter output currents (iS1, iS2, iS3) and a measured rotational-speed-proportional signal (ω) is compared with an instantaneous setpoint value (m*) determined from a measured rotational-speed-proportional signal (ω) and a predetermined rotational-speed-proportional signal (ω*), in such a way that in the case of inequality a signal (SRS) is generated which indicates that the rotating stall fault has occurred. In this way, it is possible for the rotating stall fault to be detected without pressure sensors and/or oscillation pickups in a compressor (12) which is driven with a three-phase current motor (8) fed by inverter.

Abstract: To provide a vacuum pump capable of performing temperature control using one or more heating devices or cooling devices fewer than the number of temperature sensors arranged in the pump.One temperature sensor is arranged for each target in the pump, while only one set consisting of a heater 147 and a magnetic valve 163 is arranged. One set consisting of a heater and a magnetic valve is controlled based on output signals from a plurality of temperature sensors, based on the priorities set for the temperature sensors. As stated above, by setting priorities for the temperature sensors, the temperature of a target provided with a temperature sensor given a higher priority is settled within a control range by performing quick ON/OFF control, and then the temperature of a target provided with a temperature sensor given a lower priority is settled within the control range.

In some cases, the one or more pressure switches may be used to calculate one or more operating points for the combustion blower. Additional operating points may be calculated by interpolation and/or extrapolation, as appropriate. The furnace may temporarily alter these operating points as necessary to keep the furnace safely operating in response to minor and/or transient changes in the operating conditions of the furnace.
