Low-water pressure
The response time for the
low-water pressure alarm
signal can be programmed
from 1 to 999 seconds.
The
controller
can
be
programmed to allow a few
more attempts to switch on
the system on if the water
pressure is low before it cuts out completely. It can only then be switched
back on by pressing "ON". A setting of between 0 and 9 is permissible.
If you select
0
, the system does not cut out completely. The system comes
back on as soon as the low-water pressure signal disappears and water is
requested.
If you select
1
, the system cuts out and must be restarted manually.
If you select values of between
2 and 9
, the system makes 1-8 attempts to
come back on, despite the current low-water pressure alarm signal. It then
cuts out and must be restarted manually.
If between 2 and 9 at-
tempts
to
switch
the
system
back
on
are
programmed,
the
delay
between automatic switch-on attempts must be set. You may specify a delay
of between 1 and 999 seconds.
You can define the phases
in which the low-water
pressure
input
is
monitored.

P
= Production phase
R3 = Rinse during production phase
R1 = Rinse after production phase
M
= Maintenance phase
R2 = Rinse during standby phase
S1 = Standby phase 1
The low-water pressure input is not monitored during the stop and standby
phases as the high-pressure pump is shut off.
External alarm switch
The response time for the
external alarm switch can
be programmed from 1 to
999 seconds.
You can specify whether or
not the system cuts out
and the stop phase is
activated if a fault occurs
or if an alarm signal is simply displayed.
