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

11 Troubleshooting

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

WARNING
Remedy
Check tubing diameter
Check tubing and tubing connections
Troubleshooting using the LED
display
(Normal state: RUN, IN 1, IN 2 and
OUT illuminate, ERR is off)
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 using the
flash code and carry out
troubleshooting in accordance with
"Signal sequence when a fault
occurs".
Explanation of errors Remedy
Supply voltage too low Increase the power supply. Use
a cable with a larger diameter
Supply voltage too Reduce the power supply

If you are unable to troubleshoot the AS3-SV safety valve malfunction yourself:
O
Disassemble the AS3-SV safety valve as described in chapter 9 "Disassembly and Exchange"
and send it to AVENTICS GmbH. You can find the address on the back of the operating
instructions.
