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.
Code Description
3201 SUPERV 1 PARAM
Selects the first supervised parameter.
• Must be a parameter number from Group 01: OPERATING
DATA.
•100 =
NOT SELECTED – No parameter selected.
• 101…178 – Selects parameter 0101…0178.
• 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 SUPRV2 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 SUPRV1 UNDER or SUPRV2 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.
LO HI
Operating data supervision using relay outputs, when LO>HI.
The lowest limit (
HI 3203) is active initially and remains active
until the supervised parameter goes above the highest limit
(LO 3202), making that limit the active limit. That limit remains
active until the supervised parameter goes below the lowest
limit (
HI 3203), making that limit active.
• Case A = Parameter 1401
RELAY OUTPUT 1 (or 1402 RELAY
OUTPUT 2, etc.) value is SUPRV1 OVER or SUPRV2 OVER.
Initially the relay is de-energized. It is energized whenever
the supervised parameter goes above the active limit.
• Case B = Parameter 1401
RELAY OUTPUT 1 (or 1402 RELAY
OUTPUT 2, etc.) value is SUPRV1 UNDER or SUPRV2 UNDER.
Initially the relay is energized. It is de-energized whenever
the supervised parameter goes below the active limit.
LO  HI
Note: Case LO HI represents a normal hysteresis.
LO > HI
Note: Case LO>HI represents a special hysteresis with
two separate supervision limits.
3202 SUPERV 1 LIM LO
Sets the low limit for the first supervised parameter. See
3201
SUPERV 1 PARAM above.
3203 SUPERV 1 LIM HI
Sets the high limit for the first supervised parameter. See
3201
SUPERV 1 PARAM above.
3204 SUPERV 2 PARAM
Selects the second supervised parameter. See 3201
SUPERV 1 PARAM above.
3205 SUPERV 2 LIM LO
Sets the low limit for the second supervised parameter. See 3204
SUPERV 2 PARAM above.
3206 SUPERV 2 LIM HI
Sets the high limit for the second supervised parameter. See 3204
SUPERV 2 PARAM above.
