Level vessel
OFF
Minimum fill level vessel ON:
Default setting has been reached or not achieved; pump motor
1; 2 is turned off; with top-up feature installed, top-up is ON
(rising level starting at 0%); see error no.: Error OFF: self-
resetting when error resolved.

Minimum priming water ON:
Default setting has been reached or not achieved; pump motor
1; 2 is turned OFF, no pressure increase; may be followed by
error no.: 8; execution without top-up feature, insufficient initial
filling or as consequence of error no.: 22-27 / check top-up
functioning, leaks in equipment, system lay-out; if necessary
re-fill manually, beware of error no: 11! Error OFF: self-resetting
when error resolved.

Maximum fill level vessel ON:
Default setting has been reached or exceeded;
Valves 1; 2 (3 is OFF) are switched OFF, pump motor 1;
2 are not switched ON; no pressure increase or decrease;
following error may be error no.:(8) 9; improper system lay-out
of initial filling / check functioning of valves 1; 2; 3; check check
valves, expansion volume, drain system water (beware of error
no.: 19); Error OFF, when error is resolved and reset.

Diaphragm rupture (optional)
OFF
Diaphragm rupture sensor ON:
Water at the electrodes of the conductive sensor; pump motors
1; 2 and 1; 2; 3 valves are turned off, no pressure increase,
reduction and top-up;
may be followed by error no.: 8; 9; probably diaphragm
rupture/open condensate drain. If the opening results in water
discharging continuously, the diaphragm should be visually
checked for ruptures and leaks (note: inspect the vessel
internally, which is part of the routine vessel inspection), clean
the inside of the vessel, if necessary service; Error OFF, when
error is resolved and reset.

Level top-up pump (optional)
OFF
Minimum fill level top-up pump ON:
Insufficient level in break tank of top-up unit;
top-up pump is turned off, no top-up function,
feed pressure is too low, feed-valve with insufficient flow rate,
may be followed by error-no.: 8; 10; 19 /
check feed conditions; Error OFF, self-resetting when error is
resolved.
