210 Actual signals and parameters
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.

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
RELAY OUTPUT 1 (or
1402 RELAY OUTPUT 2,
etc.) value is SUPRV1
OVER or SUPRV 2 OVER.
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 RELAY OUTPUT 1 (or 1402 RELAY OUTPUT 2, etc.)
value is SUPRV 1 UNDER or SUPRV 2 UNDER. 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.
Note: Case LO ≤ HI represents a normal hysteresis.
