Cntactor Dly
Range: 100 to 800 milli-seconds Default: 160 ms Scaling: 4 Type: R/W
‘Contactor Delay’. Following a start command, this is the delay allowed for the main incoming
contactor to close. After this time, a phase loss detection routine checks the incoming supply.
Trip Snstvty
Range: 1 to 15 Default: 1 Scaling: 1 Type: R/W
‘Trip Sensitivity’ holds an arbitrary number to adjust the sensitivity of the fault trips of P-127,
‘Hidden Trip Flags’. The larger the setting of P-72, the slower the trips of P-127.
Affected trips (P-127 ‘Hidden Trip Flags’):
Trip 1 – ‘Phase Loss’
Trip 4 – ‘SCR Firing’ (Thyristor Sensing Trip Type C)
Trip 5 – ‘SCR Signal’ (Edge Sensing Trip)
Trip 6 – ‘SCR Signal’ (Sensing Trip Type A)
Trip 7 – ‘Sensing Signal’ (Sensing Trip Type B)
Trip 8 – ‘SCR Loss Motor’ (Motor-Side Thyristor Loss)
Trip 9 – ‘Sensing Signal’ (Thyristor Sensing Trip Type A)
Trip 10 – ‘SCR Shorted’ (Thyristor Sensing Trip Type B)
Last Trip
Range: 0 to 17 trip number Default: 0 Scaling: 1 Type: R
‘Last Trip’ holds the number of the last trip.
• Trip #:
E0 – no trip
E1 – Phase Loss
