Servicing and troubleshooting
6.2.1
Maintenance
With the exception of the relays and the buttons, devices from the AS2.x series work without
mechanical wearing parts. Their components are almost all over-dimensioned for a long
service life. We only use high-quality parts. If properly operated and the installation
instructions are followed, constant maintenance is not required. See the "Technical data" for
the service life of our relays.
The system must be checked/serviced in accordance with the regulations of KVU, TTV,
SEV, etc. Special overspill protection systems every 3 years/leakage monitoring every
2 years by Aquasant Messtechnik AG or a licensed company.
6.2.2
Function test
The general function test via the measuring system is based on the country-specific
requirements that must be observed. In Switzerland, the SVTI/KVU technical rules apply.
These state that, depending on the application, annual tests must be carried out when
monitoring water-polluting liquids. The AS2.x control device can check all internal LEDs,
alarms and fault alarms by using the "Test" button. This simulates checking the connected
external components. If the «test» button is pressed for <5s, the sensor reading, system
check, serial no. and firmware shown on the display. If the button is pressed longer >5s, the
relays drop out, the status LED changes to red and the yellow LEDs light up. The sensor or
detector readings are checked with a tester and additionally via a wet test.
6.2.3
Cleaning
Before cleaning, the control device must be switched off and disconnected from the mains.
The device must not be penetrated with any object and the enclosure must not be opened.
The enclosure can be cleaned with a dusting brush or a damp cloth. If the device is very dusty,
it can be cleaned with gentle compressed air.
Caution: Pressing the "Test" button switches off all the valves and pumps that are
controlled downstream.
Do not immerse the device in water or pour water over it and do not clean it with
solvent. When repairs are done, Aquasant carries out the cleaning. However, this
work is not covered by the manufacturer's warranty. If the device is not used for a
longer period of time, it must be protected from dust and dirt.

Procedure for repair
You must not operate a damaged device. If the connector or the enclosure is defective or the
control device has been dropped or damaged in any other way, please return it immediately
to the Aquasant® point of sale for repair or a follow-up check.
Electrical repairs may only be carried out by an electronics specialist from Aquasant
Messtechnik AG. No liability is accepted for any damage caused by incorrect repairs.
Incorrect repairs also void the warranty.
