NO. OF STATOR SLOTS
Range: 1 to 500 in steps of 1
Default: 0
Configure the number of stator slots based on the motor design. This information is
available from the manufacturer or found in the motor technical manuals.
BEARING FAULT PKP STAGE 1(2)
Range: 1 to 100 dB in steps of 1 dB
Default: 10 dB (20 dB)
Configure the minimum dB level above the baseline dB level (for any load bin) at which
the bearing fault operand level 1 (level 2) picks up. This setting is applicable to both peak
magnitude and energy at peak magnitude.
BEARING FAULT PKP DELAY 1(2)
Range: 5 to 60 min in steps of 5 min
Default: 15 min
Configure the delay in minutes after which the bearing fault operand pickup level 1 (level
2) will operate if the level sustains.
MECH FAULT PKP STAGE 1(2)
Range: 1 to 100 dB in steps of 1 dB
Default: 10 dB (20 dB)
Configure the minimum dB level above the baseline dB level (for any load bin) at which
the bearing fault operand level 1 (level 2) picks up. This setting is applicable to both peak
magnitude and energy at peak magnitude.
MECH FAULT PKP DELAY 1(2)
Range: 5 to 60 min in steps of 5 min
Default: 15 min
Configure the delay in minutes after which the bearing fault operand pickup level 1 (level
2) will operate if the level sustains.
STATOR FAULT PKP STAGE 1(2)
Range: 1 to 100 dB in steps of 1 dB
Default: 10 dB (20 dB for stage 2)
Configure the minimum dB level above the baseline dB level (for any load bin) at which
the bearing fault operand level 1 (level 2) picks up. This setting is applicable to both peak
magnitude and energy at peak magnitude.
