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
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
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 (
the supervised parameter goes above the highest limit (
making that limit the active limit. That limit remains active until the
supervised parameter goes below the lowest limit (
that limit active.
• Case A = Parameter 1401
2, etc.) value is
de-energized. It is energized whenever the supervised parameter
goes above the active limit.
• Case B = Parameter 1402
2, etc.) value is
is energized. It is de-energized whenever the supervised parameter
goes below the active limit.
