Installation and operating instructions Tagus Vac 7-30
Reset
Possible cause
B
• Leakage
• Pressure-holding value wrongly set
• Wrong admission pressure
• Filling pressure too low
B
• Pump does not switch off
• Diaphragm expansion vessel too small/
wrong admission pressure
• Filling pressure too high
A
• No pulses sent from litres counter,
because:
• litres counter defective
• cable not connected
• setting value too low for litres counter
response time
A
• Leakage in system
• False setting value
A
• Leakage in system
• False setting value
A
• Leakage
• Solenoid valve don't close/defective
A
• Leakage
• Setting value for flow rate reduction
too low
A
• Leakage
• Setting value for flow rate reduction
too low
• Pump doesn't deliver
A
• Module capacity (water treatment)
exhausted
A
• Sensor defective
• Terminal/cable defective
A
• Sensor defective
• Terminal/cable defective
• Short circuit
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
B
• Vent. device defective
• Strainer / inlet protected
• Valves closed
A Necessary, reset possible within normal use
(control restarts after resetting).
B No duty, automatic reset within normal use.
Troubleshooting
• Eliminate leakage
• Set correct pressure-holding value
• Increase filling pressure up to working
pressure range
• Check control
• Check admission pressure / use larger
diaphragm expansion vessel
• Lower filling pressure to working
pressure range
• Replace litres counter
• Connect cable
• Use higher setting value for response
time
• Eliminate leakage
• Eliminate leakage
• Program correct settings
• Eliminate leakage
• Replace solenoid valve
• Eliminate leakage
• Correct the setting value
• Eliminate leakage
• Correct the setting value
• Deaerate pump
• Replace module
• Replace sensor
• Check/exchange terminal/ cabling
• Replace sensor
• Check/exchange terminal/ cabling
• Take steps for ensuring return
temperatures below 70°C!
• Replace pump
• Locate leakage in Tagus Vac 7-30
• Clean or replace vent. Device
• Clean or replace vent. Device
• Clean strainer
• Open valves
