Group 32: SUPERVISION
This group defines supervision for up to three signals from
Group 01: OPERATING
parameter and energises a relay output if the parameter passes
a defined limit. Use
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
• 101...178 – Supervises parameter 0101...0178.
• If the supervised parameter passes a limit, a relay output is
energised.
• The supervision limits are defined in this group.
• The relay outputs are defined in
(definition also specifies which supervision limit is monitored).
LO ≤ HI
Operating data supervision using relay outputs, when LO ≤ HI. See the
figure on page 254.
• Case A = Parameter 1401
etc.) value is
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
etc.) value is
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. See the
figure on page 254.
The lowest limit (
supervised parameter goes above the highest limit (
that limit the active limit. That limit remains active until the supervised
parameter goes below the lowest limit (
active.
• Case A = Parameter 1401
etc.) value is
energised. It is energised whenever the supervised parameter goes
above the active limit.
• Case B = Parameter 1401
etc.) value is
energised. It is de-energised whenever the supervised parameter
goes below the active limit.
