Troubleshooting
A1
System error motor/limit switch
The
isolating valve cannot be operated,
possibly due to dirt or a motor or limit
switches’ error
.
- Press . Another start attempt
is made .
- Contact the SYR service
0800/6105000.
A3
Suspected leakage: volume-based
Admissible limit value for volume is
exceeded during fiilling, possibly due to
leakage or because the limit value was
too low .
- Press to open the isolating
valve and continue refill process
- Adjust the protection level or
remove the leak.
- Remote action via the SYR App
or the web application at http://
syrconnect .de is also possible
A4
Suspected leakage: flow-rate-
based
Admissible limit value for flow rate is
exceeded during filling, possibly due to
leakage or because the limit value was
too low . .
- Press to open the isolating
valve and continue refill process
- Adjust the protection level or
remove the leak.
- Remote action via the SYR App
or the web application at http://
syrconnect .de is also possible
A5
Malfunction or alarm conductance
sensor
The conductance sensor sends no si-
gnal or the capacity of the HVE/HVE-
Plus cartridge is spent. .
- Replace cartridge. Once the
cartridge is exchanged, vent the
system. Ensure that the cable
is correctly connected and the
function is active.
- Contact the SYR service.
A6
Batteries are spent
- Replace the batteries.
A7
Capacity of cartridge is depleted
- Fill the cartridge or replace the
empty cartridge by a full one.
A8
Suspected leakage, time-based
During the filling, the admissible
filling time was exceeded, potentially
causing leakage or the selected limit
value had been too low.
- Press to open the isolating
valve and continue refill
process, adjust the protection
level or remove the leak.
- Remote action via the SYR App
or the web application at http://
syrconnect .de is also possible
A9
Number of filling cycles exceeded
During the filling, the admissible
number of filling cycles was exceeded,
potentially causing leakage or the
selected limit value had been too low.
- Press to open the isolating
valve and continue refill
process, adjust the protection
level or remove the leak.
- Remote action via the SYR App
or the web application at http://
syrconnect.de is also possible -
AA
Minimum filling volume not reached
During the filling, the minimum filling
quantity has not been reached within
a determined period of time after the
start of the filling process.
- Press to open the isolating
valve and continue refill
process, check whether the
inlet pressure is sufficient and
the flow sensor emits impulses
