6 MTU Installation Requirements
Trend Mode
Transmit Interval
The transmit interval for Trend Mode is pre-configured at six times the read
interval. That is:
• If a 1 minute read interval is selected, the transmit interval will be 6 minutes.
• If a 5 minute read interval is selected, the transmit interval will be 30 minutes.
If Trend Mode is canceled from the NCC or if the MTU receives a clear pressure
alarm signal from the instrument, the MTU will notify the NCC that only six more
readings will be received in Trend Mode. The MTU will read and transmit the
remaining Trend Mode reads, before it switches back to normal operating mode.
If Trend Mode is initiated manually via the NCC, it will continue for a maximum
of 30 minutes if it is not manually canceled from the NCC.
Trend Mode data is recorded and stored along with graphical representations in the
NCC for up to 13 months.
