Electrical supply failure.
If there is a failure of the power supply no status information will be lost. The control panel "remembers"
the condition it was in when the supply is interrupted.
NB.

IMPORTANT!
If the plant is in a regeneration cycle when the power supply fails it is possible for the unit
to become partially exhausted, by the passage of water to drain, if the water supply is maintained during

In this situation the regeneration cycle should be terminated and a new cycle initiated first ensuring
sufficient chemicals are available.

then reset the current time.
Refill chemical tank.

IMPORTANT! One regeneration cycle will be performed after this message appears. and regeneration
may still be initiated by pressing the "REGENERATION START" key indicated by the symbol
.
Press the "UNLOCK" key indicated by the symbol
, in order to reset the warning or alarm relay. The
message will then clear when regeneration chemicals are available.
With duplex plant operating in standby mode the standby unit will automatically be brought into service
even though regeneration of the exhausted column cannot take place.
