7.5 Error messages
A
Necessary, reset possible within normal use
(control restarts after resetting).
B No duty, automatic reset within normal use.
Nr Message Description Reset Possible cause Troubleshooting
1 Pressure too low System pressure too
low, is outside working
pressure range B • Leakage
• Pressure-holding value wrongly set
• Wrong admission pressure
• Filling pressure too low • Eliminate leakage
• Set correct pressure-holding value
• Increase filling pressure up to working
pressure range
2 Pressure too
high System pressure too
high, is outside working
pressure range B • Pump does not switch off
• Diaphragm expansion vessel too small/
wrong admission pressure
• Filling pressure too high • Check control
• Check admission pressure / use larger
diaphragm expansion vessel
• Lower filling pressure to working
pressure range
3 Entrycap. too
low Litres counter does not
supply water after
make-up request A • No pulses sent from litres counter,
because:
• litres counter defective
• cable not connected
• setting value too low for litres counter
response time • Replace litres counter
• Connect cable
• Use higher setting value for response
time
5 Cycle interval Make-up cycle interval
too short A • Leakage in system
• False setting value • Eliminate leakage
6 Nr. of cycles Maximum number of
cycles within time
window exceeded A • Leakage in system
• False setting value • Eliminate leakage
• Program correct settings
7 Fill error
Filling without request
(litres counter sends
signal without filling) A • Leakage
• Solenoid valve don‘t close/defective • Eliminate leakage
• Replace solenoid valve
8 Quantity limit Maximum quantity in a
make-up cycle exceeded A • Leakage
• Setting value for flow rate reduction
too low • Eliminate leakage
• Correct the setting value
9 Runtime
protection Maximum time of
make-up cycle exceeded A • Leakage
• Setting value for flow rate reduction
too low
• Pump doesn‘t deliver • Eliminate leakage
• Correct the setting value
• Deaerate pump
10 Exchange
module Softening module
exhausted A • Module capacity (water treatment)
exhausted • Replace module
11 Low mA
P-sensor Interruption of current
loop of pressure
sensor A • Sensor defective
• Terminal/cable defective • Replace sensor
• Check/exchange terminal/ cabling
12 High mA
P-sensor Short-circuit in current
loop of pressure sensor A • Sensor defective
• Terminal/cable defective
• Short circuit • Replace sensor
• Check/exchange terminal/ cabling
13 Vacuum error 3 times in succession
insufficient vacuum for
dearation A • Temperature in return branch higher
than 70 °C
• Pump does not operate continuously
• Leakage in Tagus Vac 7-30
• Vent. device doesn‘t close • Take steps for ensuring return
temperatures below 70°C!
• Replace pump
• Locate leakage in Tagus Vac 7-30
• Clean or replace vent. Device
14 Level switch
error Low level B • Vent. device defective
• Strainer / inlet protected
• Valves closed • Clean or replace vent. Device
• Clean strainer
• Open valves
