- Volume sensor < 4 mA
Signal out of sensor range or not connected, no volume read-
out/ check electrical installation, threaded round connector or
sensor range; change sensor if necessary» service; Error OFF:
self-resetting when error resolved.
Pressure
8-4- 1
Minimum operating pressure ON (actual pressure):
Default setting has been reached or not achieved; lockshield
valves in vessel or return connection in incorrect position,
insufficient capacity of pumps, improper system layout, or as
consequence of error no.: 10-16; 15-17; 19; 20; 22-27 /, check
system lay-out, electronic installation, pumps, leak-tightness
of the equipment and system and lockshield valves; insufficient
capacity diagnosed » service; Error OFF: self-resetting when
error resolved.
Maximum operating pressure ON (actual pressure):
Default setting has been reached or exceeded; lockshield valves
in return connection in incorrect position, improper system
layout, or as consequence of error no. : 11; 20 / check system
lay-out, electronic installation, valve 1; 2 , particle filter, return
connection, lockshield valve;
if necessary » service; Error OFF: self-resetting when error
resolved.
8-4- 2 Level vessel
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-reset-
ting 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 er-
ror 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; fol-
lowing 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)
8-4- 3
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 discharg-
ing 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.
