Common Relay parameters
P216, 226, 236, 246, 256 – Relay Allocation
This parameter determines which input the relay will act on. You can set it to
the transducer (default), or the optional auxiliary (current) input, or an
average of the two. In most cases, this will not need to be changed from the
default.
OPTION DESCRIPTION
1 = Xducer 1 (Default)
Relay acts on Xducer 1 calculated values
P217, 227, 237, 247, 257 – Relay Closures
The FlowCERT will record how many times each relay is closed, this
parameter displays the number of times the relay has activated since the
relay has been in use. It can be reset with any value.
P218, 228, 238, 248, 258 – Relay Fail Safe
The FlowCERT has a general fail-safe parameter P808 . However, this can be
overridden so that each individual relay has its own independent fail-safe
mode.
This parameter determines what the relay will do in the event of the
Failsafe
Time ( P809 ) expiring.
OPTION DESCRIPTION
0 = Default
Relay assumes system default mode set in P808
1 = Hold
Relay remains in its current state
2 = De-energise
Relay will De-energise
3 = Energise
Relay will energise
