Parameter Setting for Temperature Averaging
With process control equipment disabled, enter the RUN mode to monitor system
performance and alarm programming. (A Reading Measurement simulation (P920) may
be performed to verify mA output programming).
When satisfied with system performance and programming, connect mA output 1 to the
Programmable Logic Controller (PLC).
Note that on power off the mA output drops to 0.00 mA. During a power interruption, the
last known mA output value is maintained in memory for 1 hour minimum. If power is
interrupted beyond 1 hour, on power resumption, the mA output immediately assumes the
new value.
