Data control
VENTILATION
DESCRIPTION
It is an alarm signal, indicating when a critical status
is reached for the functioning of the controlled
equipment.
ACTIONS
- The FAN relay energizes
- The related FAN led switches on
INTERVENTION
- When the temperature of a channel is higher than
the limit of the threshold parameter "H"
- When the temperature of a channel has exceeded
the limit of the threshold parameter "H" and isn't
lower than the limit of the threshold parameter "L"
- To avoid the binding of the blowers bearings when
the control parameter "C" is set on value 1 or 2
- As a precaution, in case of one or more damaged
probes
FAULT
DESCRIPTION
This is an anomaly of the temperature detection
system due to the power unit, the probes or the
connections. The FAULT signal is not switched off
automatically because even if the channel is
acknowledged within the parameters, this does not
imply the problem has been solved.
ACTIONS
- The FAULT relay energizes
- The related FAULT led flashes
Quick flashing: display of damaged channel
Slow flashing: signals that at least one
currently not displayed probe is damaged.
By placing on the related damaged channel,
