9.6 LAN error alarm

If the connection to the LAN network is o ine for more than 6s due to an
electrical problem, the incorrect confi guration of the network addresses
or the malfunction of the pCO controller, a LAN error alarm will be
signalled.
The LAN error aff ects the control of the driver as follows:
•
case 1: unit in standby, digital input DI1/DI2 disconnected; the driver
will remain permanently in standby and control will not be able to
start;
•
case 2: unit in control, digital input DI1/DI2 disconnected: the driver
will stop control and will go permanently into standby;
•
case 3: unit in standby, digital input DI1/DI2 connected: the driver will
remain in standby, however control will be able to start if the digital
input is closed. In this case, it will start with "current cooling capacity"=
100%;
•
case 4: unit in control, digital input DI1/DI2 connected: the driver will
remain in control status, maintaining the value of the "current cooling
capacity". If the digital input opens, the driver will go to standby and
control will be able to start again when the input closes. In this case, it
will start with "current cooling capacity"= 100%
