DIAGNOSTICS
In case of anomalies, the
VISION SC600
controller warns the operator using alarm codes
shown by the display and an acoustic signal emitted by a buzzer inside the Operational
console.
When there is an alarm, the
icon starts flashing on the display, the alarm relay is
activated, as well as the internal buzzer and one of the alarm codes is displayed (the code
is alternated with the page normally displayed).
The internal buzzer can be silenced at any time by pressing the "Sound off" key. Press the
SET key (compressors or fans) to reset the audio signal. If an alarm has been silenced
and another kind of alarm is tripped (a different one from the one currently reported), the
audio signal goes off again and the error code will be shown based on the display priority.
There can be two kinds of alarm based on how serious they are:
- Automatic set (the alarm is automatically reset when the problem is cleared);
- Manual reset from the keyboard (the alarm is reset once it has been acquired by the
operator via the "Sound off" key).
When the alarm is cleared, the
icon stops flashing and becomes steady to tell the
operator that an alarm with an automatic reset was tripped and is no longer activated. The
display goes back to showing the normal page and the alarm code is no longer shown.
When the "Sound off" key is pressed, the steady
icon turns off. The alarm code with the
top priority tripped is saved and can be displayed (read-only) in the first-level ALL variable.
The view of this variable at the first commissioning (with empty memory) will display - - -.
The alarms are displayed in the following order of priority: E0, E0n, E1, E2, EH, EL, EHc,
ELc, EHu, ELu, E8, EF,
EC1….EC0, EU1….EU0, EC, Eu, EO5, E7, EP, En, E6.
