6.11.2. Monitoring minimum transmembrane pressure
For monitoring purposes the minimum limit of 0,1 to 1000,0 can be entered.
A delay can also entered (1-9999 sec). During the delay the measured value has to be under the limit
so an alarm is given if the unit is switched off.
You can set if the unit actually is switched off (“Switch off”).
If monitoring is enabled here, it will be activated during the “Filtration” phase. This is adjustable. This
will automatically be switched off during the other phases.
6.11.3. Monitoring maximum transmembrane pressure
For monitoring purposes the maximum limit of 0,1 to 1000,0 can be entered.
A delay may also be entered (1-9999 sec). During the delay the measured value has to be under the
limit so an alarm is given if the unit is switched off.
You can set if the unit is actually switched off (“Switch off”).
If monitoring is enabled here, it will be activated during the “Filtration” phase. This is adjustable. This
will automatically be switched off during the other phases.
If monitoring is enabled here, a backwash can be initiated when the transmembrane pressure is above
the programmed limit for the programmed time.
After backwashing, the transmembrane pressure is monitored again and if the calculated pressure is
much higher again than within the set delay time + 20 seconds, then an alarm will sound and the
controls will be disabled.
Should the transmembrane pressure still be below the maximum limit after 20 seconds, a backwash
will be then started again at the next time the limit value is exceeded.
