PV retrans
Ht output
retrans
PV 1
Choose to retransmit the loop 1 process variable.
PV retrans
Ht retrans
LowPV
0˚F
This is the input value represented by a 0 percent
output signal. The recorder input is a linear 4 to 20
mA signal representing a range of 0° F to 1000° F,
so we will use a 0 percent output signal to represent
0° F.
PV retrans
Ht retrans
HighPV
1000˚F
This is the input value represented by a 100 percent
output signal. The recorder input is a linear 4 to 20
mA signal representing a range of 0° F to 1000° F,
so we will use a 100 percent output signal to repre-
sent 1000° F.
PV retrans
Cl output

Not using the cool output of loop 2 to retransmit a
process variable.
