32 SUPERVISION

3201 SUPERV 1 PARAM
Description
Signal supervision. Supervision status can be monitored with relay or
transistor output. See parameter groups
IN & TRAN OUT.
Selects the first supervised signal. Supervision limits are defined by
parameters 3202 SUPERV 1 LIM LO and
Example 1: If 3202 SUPERV 1 LIM LO <
Case A = 1401 RELAY OUTPUT 1 value is set to SUPRV1 OVER. Relay
energises when value of the signal selected with
exceeds the supervision limit defined by
remains active until the supervised value drops below the low limit defined by
3202 SUPERV 1 LIM LO.
Case B = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 UNDER. Relay
energises when value of the signal selected with
drops below the supervision limit defined by
relay remains active until the supervised value rises above the high limit
defined by 3203 SUPERV 1 LIM HI.

Example 2: If 3202 SUPERV 1 LIM LO >
The lower limit 3203 SUPERV 1 LIM HI remains active until the supervised
signal exceeds the higher limit
limit. The new limit remains active until the supervised signal drops below the
lower limit 3203 SUPERV 1 LIM HI, making it the active limit.
Case A = 1401 RELAY OUTPUT 1 value is set to SUPRV1 OVER. Relay is
energized whenever the supervised signal exceeds the active limit.
Case B = 1401 RELAY OUTPUT 1 value is set to SUPRV1 UNDER. Relay is
de-energized whenever the supervised signal drops below the active limit.
