9. Probe Purge Timing Diagram
1. When probe purge function is accomplished through this Data Logger’ s D/O
unit, please refer to manual’ s page85 and page86 for parameter setting of
necessary items.
2. For example, if purge period: 300m, purge duration: 60sec, and purge hold:
120sec are set, timing diagram is as follows.
PURGE PERIOD = 300 min
PURGE 1
10 sec 10 sec
PURGE 2
PURGE DURATION = 60 sec
3. That is, operation timing goes every 300 minutes as above. Then outputs are
D/O points, which are set with purge 1 and 2 of relevant item.
4. If purge function is accomplished with one contact point such as purge1 or 2,
purge contact point which is not-in-use must to be set its number above 32.
5. This function is needed to achieve probe purge function in Data Logger.
If exclusive purge controller is used here, purge D/O contact point must be set
by 255 necessarily.
