If a fault occurs, this will be indicated by a
red display
and the fault indication in the
bottom line.
For a description of the fault indications,

.
Faults must be pending for 6 seconds before a notification or an alarm is triggered.
A distinction is made between
alarms
(software alarms, e.g., dosing time monitoring,
monitoring switch) and
notifications
(e.g., “Chlorine empty”).
Examples for fault indications / alarm
Dos-limit Cl = Dosing time limit for chlorine exceeded
pH empty = pH (= acid canister) empty
Cl empty
= Chlorine tank empty
fuse F2
= Fuse F2, for details, see
Chapter

Notice!
An alarm will be automatically deleted when its cause has been remedied. For example,
when the empty chemical container has been exchanged with a full one.
Acknowledge alarm
Use the Enter key to switch to the main menu
Use the arrow keys to navigate to the menu item “Reset alarm”
Touch the Enter key
The alarm relay is temporarily deactivated; this does not rectify the fault! If the fault subsequently recurs,
or if the fault is not rectified, the alarm relay will be reactivated.
Navigate back to the operation mode; this will restart the device.
Special cases
The two alarms for the dosing time monitoring
“Dos-limit” cannot automatically be deleted and must
always be acknowledged manually
!
In case of the faults
“pres. min”
or
“Level min”
the
startup mode
starts 5 times for 120 seconds each
to check whether the fault is still pending. (See 6.2.2)
o
If the fault is rectified during the 5 startup attempts, the device returns to the previous state, e.g.,
automatic operation.
o
If the fault still continues after this, the GRANUDOS switches off.
o
If the GRANUDOS has switched off, the fault must be acknowledged manually. To do so, the “Reset
alarm” command must be carried out twice: Once to reset the alarm, and once to reset the startup
delay. Now, the GRANUDOS will start up again and the cause of the fault can be investigated.
