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.
Note: Case LO > HI represents a special hysteresis with two separate supervision
limits.
3202
SUPERV 1 LIM LO
Depends on selection - 60.0
Sets the low limit for the first supervised parameter. See parameter 3201 SUPERV 1
PARAM above. Supervision wakes up if the value is below the limit.
3203 SUPERV 1 LIM HI Depends on selection - 60.0
Sets the high limit for the first supervised parameter. See parameter 3201 SUPERV 1
PARAM above. Supervision wakes up if the value is above the limit.
3204 SUPERV 2 PARAM 101…178 1 104
Selects the second supervised parameter. See parameter 3201 SUPERV 1 PARAM
above.
3205 SUPERV 2 LIM LO Depends on selection 4.5
Sets the low limit for the second supervised parameter. See parameter 3204 SUPERV
2 PARAM above. Supervision wakes up if the value is below the limit.
3206
SUPERV 2 LIM HI
Depends on selection 4.5
Sets the high limit for the second supervised parameter. See parameter 3204
SUPERV 2 PARAM above. Supervision wakes up if the value is above the limit.
3207 SUPERV 3 PARAM 101…178 1 105
Selects the third supervised parameter. See parameter 3201 SUPERV 1 PARAM
above.
