11 Disposal

Dispose of the AS3-SV safety valve in accordance with the currently applicable
u
regulations in your country.

12 Troubleshooting

Danger of injury by dismantling the valve!
Compressed and loaded springs may suddenly be released when dismantling
the valve.
1. Never dismantle the valve.
2. Do not attempt to perform any unauthorized repairs.
Check the connections, operating voltage, and working pressure of the rele-
u
vant system part if malfunctions occur.
Additional help for malfunctions can be found in the following table:
Malfunction Possible cause
Pressure/flow level is not Operating pressure is too low Increase the operating pres-
reached or drops off slowly
Leak on tubing
No output pressure on output Incorrect control

Supply a voltage to the device
according to the instructions
Check the wiring and control
of safety inputs
Check signal sequence on
IN 1 and IN 2
Check the wiring and control
of the start signal
Establish the fault number us-
ing the flash code and carry
out troubleshooting in accor-
dance with the chapter "Sig-
nal sequence when a fault oc-
curs".
Explanation of errors Remedy
Supply voltage too low Increase the power supply.
Use a cable with a larger
diameter
Supply voltage too high Reduce the power supply

If you are unable to troubleshoot the AS3-SV safety valve malfunction yourself:
Disassemble the AS3-SV safety valve as described in chapter "Disassembly
u
and exchange" and send it to AVENTICS GmbH. You can find the address on
the back of the operating instructions.
