ABB ACS150 - Supervision; Select

Actual signals and parameters

32 SUPERVISION
Signal supervision. The drive monitors whether certain user selectable
variables are within the user-defined limits. The user may set limits for speed,
current etc. Supervision status can be monitored with relay output. See
parameter group 14 RELAY OUTPUTS.
3201 SUPERV 1 PARAM Selects the first supervised signal. Supervision limits are defined by
parameters 3202 SUPERV 1 LIM LO and 3203 SUPERV 1 LIM HI.
Example 1: If 3202 SUPERV 1 LIM LO <
3203 SUPERV 1 LIM HI
Case A = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 OVER. Relay
energises when value of the signal selected with 3201 SUPERV 1 PARAM
exceeds the supervision limit defined by 3203 SUPERV 1 LIM HI. The relay
remains active until the supervised value drops below the low limit defined by
3202 SUPERV 1 LIM LO.
Case B = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 UNDER. Relay
energises when value of the signal selected with 3201 SUPERV 1 PARAM
drops below the supervision limit defined by 3202 SUPERV 1 LIM LO. The
relay remains active until the supervised value rises above the high limit
defined by 3203 SUPERV 1 LIM HI.
Example 2: If 3202 SUPERV 1 LIM LO > 3203 SUPERV 1 LIM HI
The lower limit 3203 SUPERV 1 LIM HI remains active until the supervised
signal exceeds the higher limit 3202 SUPERV 1 LIM LO, making it the active
limit. The new limit remains active until the supervised signal drops below the
lower limit 3203 SUPERV 1 LIM HI, making it the active limit.
Case A = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 OVER. Relay is
energized whenever the supervised signal exceeds the active limit.
Case B = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 UNDER. Relay is
de-energized whenever the supervised signal drops below the active limit.
