2. The conduction time monitor and total RUN time monitor cannot be used
at the same time for a single channel.
3. The total time is not calculated when the communications power to the De-
viceNet Communications Unit is turned OFF.
4. The DeviceNet Communications Unit checks the ON/RUN status of the
specified Temperature Controller approximately every 0.1 hour (6 min-
utes). Depending on the measurement timing, the accurate may not be ob-
tained due to the timing interval, as shown in the following examples.
Example 1: Using the Unit conduction time monitor when communications power is turned ON and
OFF for three minutes each (A)
In the above diagram, the actual conduction time is 3 minutes
×
3 = 9 minutes,
but the status is ON only once at the time the measurement is taken, so the
conduction time is calculated as 6 minutes.
Example 2: Using the Unit conduction time monitor when communications power is turned ON and
OFF for three minutes each (B)
In the above diagram, the actual conduction time is 3 minutes
×
3 = 9 minutes,
but the status is ON only twice at the time the measurement is taken, so the
conduction time is calculated as 12 minutes.
Example 3: Using the Unit conduction time monitor when communications power is turned ON for 9
minutes, OFF for 3 minutes, and ON for 9 minutes
In the above diagram, the actual conduction time is 9 minutes
×
2 = 18 min-
utes, but the status is ON four times when the measurement is taken, so the
conduction time is calculated as 24 minutes.
