3.2.3.4 Explanation PerPur 200 Display
Die pure water system PerPur 200 is equipped with an extended set of system controls.
This model has all the displays and functions of the models already described. In addition it
has the two additional displays and functions described below.
(1)
(2)
(1) LED Maintenance:
This yellow LED, when lit, demands that unplanned mainte-
nance be carried out in addition to the regular service cycle of
6 to 8 months. This can happen because the separating mem-
brane has been overworked and internal regulation is no
longer able to set the required performance parameters.
Another possibility is that the pumping rate has fallen steeply
but this was not to be expected.
When this LED lights up, the DRAABE Customer Service must
definitely be informed. The system will produce for another 14
days before it shuts itself down. When the problem is solved,
the LED is turned off by a reset at the network switch.
(2) LED Pump fault: If pumping pressure reaches a fixed upper boundary value
(excessive pressure), the system shuts itself down and this
red LED lights up. Please inform the DRAABE Customer Ser-
vice in such a case. The LED can be turned off through a reset
at the network switch.
