Operation
Active messages are displayed in the message line of the display. In addition to this the error LED lights up (red). The dry
operation protection is signalled directly by a separate LED (→ p. 4). If several messages are active simultaneously, these
can be directly displayed with .
Most of the messages automatically acknowledge themselves once the cause has been remedied. Errors such as „make-up
time 06“ or „make-up cycle 07“ must be acknowledged manually.
An error and parameter memory is available for subsequent analysis (→ p. 16). For remote transmission it is possible to use
the floating changer for the aggregate message, the floating contact for the dry operation protection and the RS-485 inter-
face (→ p. 17). In the customer menu (→ p. 16) it is possible to select whether only the messages characterised as alarms
or all messages will pass through the floating output.
Messages
ER Code Type of error Cause of errors Troubleshooting remedy
01 Pressure below – Water loss in the system – Correct leak
minimum pressure p
0
– Pressure maintenance incorrectly set – Acknowledge error („quit“ button)
(alarm) or defective
02.1 Dry operation protection – Water deficiency switch (16) not wired up – Wire up water deficiency switch
Time exceeded – No water enters the vacuum spray-tube
(alarm) - Ball valve on inlet side closed – Open ball valve
- Dirt trap of the pressure reducing valves – Clean dirt trap

02.2 Dry operation protection – Not enough water flows into the vacuum
Number exceeded spray-tube
(alarm) - Dirt trap of the pressure reducing – Clean dirt trap
valves (5,8) dirty
- Pressure reducing valves (5,8) or – Correct pressure setting on the pres-
overflow valve (3) incorrectly set sure reducing valves, perform hydraulic
balancing
– Dipstick tube-deaeration unit (18) defective – Replace dipstick tube-deaeration unit
04.1 Pump – Pump fuse defective – Check fuse, replace if required
fault – Pump blocked – Free pump
(alarm) – Short circuit – Establish cause and rectify
06 Make-up time – Major leaks in the system – Correct leaks, acknowledge error
exceeded (standard 20 min) – Make-up time inadequate for – Reduce make-up hysteresis
downstream pressure maintenance of the pressure maintenance
07 Make-up cycles – Minor leaks in the system – Correct leaks, acknowledge error
exceeded (standard 3 in 2 h) message
08 Pressure measurement – Pressure measuring transducer not – Check wiring, replace if required
fault (alarm) connected or defective
10 Max. pressure – Pressure losses between ’servitec’ – Incorporate pressure measuring trans-
exceeded and system excessive ducer in the system or use greater no-
minal widths for the piping to the system
– Expansion vessel in the system with – Check expansion vessel pre-pressure
incorrect pre-pressure
– Solenoid valve (4) fails to close – Inspect solenoid valve for dirt,
clean or replace if required
– PS in customer menu set too low – Co-ordinate PS setting with safety valve
activation pressure of the system
11 Make-up quantity – Major leaks in the system – Correct leaks, acknowledge error
within a make-up cycle – Make-up quantity inadequate for – Reduce make-up hysteresis of
exceeded downstream pressure maintenance the pressure maintenance or increase
maximum make-up quantity
12 Filling time – Max. filling time exceeded – Check filling status of the system,
exceeded (standard 10 h) acknowledge error and refill if required
13 Filling quantity – Max. filling quantity exceeded – Check the filling status of the system,
exceeded acknowledge error and refill if required
15 Make-up solenoid valve – Make-up solenoid valve (4) leaking – Inspect solenoid valve for dirt,
(control) (contact water meter is counting without clean or change if required
make-up request)
16 Power failure – – Check power supply
19 Stop > 4 h – ’servitec’ has been in stop mode for – Activate auto mode as applicable
more than 4 h
20 Max. make-up quantity – The maximum make-up quantity set in – Acknowledge message
exceeded (added) the customer menu has been exceeded
