Supervision - ABB ACS550-01 User Manual

ACS550 User's Manual
Group 32: Supervision
This group defines supervision for up to three signals from Group 01, Operating
Data. Supervision monitors a specified parameter and energizes a relay output if the
parameter passes a defined limit. Use Group 14, Relay Outputs, to define the relay
and whether the relay activates when the signal is too low or too high.
Code Description
3201 SUPERV 1 PARAM
Selects the first supervised parameter.
• Must be a parameter number from Group 01 Operating
Data.
• If the supervised parameter passes a limit, a relay output is
energized.
• The supervision limits are defined in this group.
• The relay outputs are defined in Group 14 Relay Outputs
(definition also specifies which supervision limit is
monitored).
LO ≤ HI
Operating data supervision using relay outputs, when LO≤HI.
• Case A = Parameter 1401
2, etc.) value is
OUTPUT
Use for monitoring when/if the supervised signal exceeds a
given limit. The relay remains active until the supervised
value drops below the low limit.
• Case B = Parameter 1401
2, etc.) value is
OUTPUT
Use for monitoring when/if the supervised signal falls
below a given limit. The relay remains active until the
supervised value rises above the high limit.
LO > HI
Operating data supervision using relay outputs, when LO>HI.
The lowest limit ( 3203) is active initially, and remains
HI
active until the supervised parameter goes above the highest
limit ( 3202), making that limit the active limit. That limit
LO
remains active until the supervised parameter goes below
the lowest limit ( 3203), making that limit active.
HI
• Case A = Parameter 1401
2, etc.) value is
OUTPUT
Initially the relay is de-energized. It is energized whenever
the supervised parameter goes above the active limit.
• Case B = Parameter 1402
2, etc.) value is
OUTPUT
Initially the relay is energized. It is de-energized whenever
the supervised parameter goes below the active limit.
3202 SUPERV 1 LIM LO
Sets the low limit for the first supervised parameter. See
3201 1
SUPERV PARAM
3203 SUPERV 1 LIM HI
Sets the high limit for the first supervised parameter. See
3201 1
SUPERV PARAM
3204 SUPERV 2 PARAM
Selects the second supervised parameter. See 3201
3205 SUPERV 2 LIM LO
Sets the low limit for the second supervised parameter. See 3204
3206 SUPERV 2 LIM HI
Sets the high limit for the second supervised parameter. See 3204
3207 SUPERV 3 PARAM
Selects the third supervised parameter. See 3201
