Entry in error list
Install a maximum pressure governor either at the raw water side or at the concentrate side in order to protect the unit. A
serial or parallel connection of two maximum pressure governors is also possible.
If the pressure governor switches, the plant is switched off after a programmable test time. The fault is displayed with the
red LED "Error message" and on the display. A continuous alarm occurs at output "Alarm" and an entry in the error list
takes place.

Funct. Excess pressure
Press the "Production" key to restart the plant. If the pressure is still too high, the plant is once again switched off after the
test time.
Note!
When operating the osmosis plant without maximum pressure governor, the connection "HP" has to be bridged and
programmed as normally open.

Entry in error list
Install a pressure switch in front of the pump in order to protect the pressure pump. A serial or parallel connection of two
pressure switches is also possible.
If the pressure switch switches, the plant is switched off after a programmable test time
. The fault is displayed with the
red LED "Error message" and on the display. A continuous alarm occurs at output "Alarm" and an entry in the error list
takes place (if
the number of restarts has been reached ).
"M"
 BASIC PROGRAM  Funct. Low water
Only for controller operation with level transmitter: It is possible to program the reaction of the controller during low water.
Determine how often the plant is to be restarted.
Restart occurs after 10 minutes (fixed). If the water is still too low, the plant is once again switched off after the test time
and until the number of restarts has been reached.
Note!
When operating the osmosis plant without a pressure governor for low water identification, the connection "LP" has to be
bridged or programmed as normally open.
