6.2 Alarm OFF status
When the machine is turned on an additional status, OFF from alarm (Alarm Off) exists. This shuts down the unit,
all devices, and closes the external air shutters completely until the alarm conditions are restored.
The central alarm will shut down to OFF status if there is no digital / supervisor consent or shut down is requested via
the keyboard. The alarms which provoke this status are as follows:
- Fan alarms
- Air Flow Meter alarm
- Fire/smoke alarm
Once alarm conditions have been restored the machine will return to normal operation.
6.3 Unit type
While the machine is turned off, using the parameter PG00 in the CONFIGURATION Menu, it is possible to choose the
type of unit that you wish to utilize. Based on the value of the parameters, different defaults become available for the
positioning of inputs and outputs.
The control and other parameters which correspond to functionalities can be modified manually according to user
requirements. The machines and their configurations are described graphically in the next paragraphs.
Note:
the default configurations can also be modified according to user requirements by entering modifications to
the parameters manually.
CAUTION!
If the type of machine is changed (modifying the parameter PG00), the controller must successively be switched off
and back on again, in order to allow correct reconfiguration of the same. Moreover, it is advised to wait for a few
moments (approx 3 seconds) to assign all parameters that have been modified.
