SCM6/1

ELETTRONICA

MAINTENANCE

The user is allowed to change the parameters, they are taken

into account immediately but they are not stored in non volatile

memory. This means that if the changeover unit is forced

to the NOMINAL status or if it’s reset, the previous saved

configuration is restored.

CONFIGURATION

The user is allowed to change the parameters, they are taken

into account immediately and stored in non volatile memory as

the “Nominal” configuration.

5.3.3 Wait menu

Using this menu one can configure the waiting times that are connected with each

transmitter.

Each line contains the value in seconds for the following intervals:

InhBit

When switched ON, the transmitter is allowed to keep the

Inhibit signal active for a time as long as the one configure

in this field. The SCM6/1 will start checking the Power Good

status only at the end of this interval or when the Inhibit signal

is deactivated.

Before

Time to wait before considering a Powerfail alarm valid. If the

PowerGood signal comes back before this interval is expired,

no switching is performed

After

This is the time allowed after a switchover before assuming a

fault in the cohaxial relay

5.3.4 Info menu

This information menu gives the details of the Firmware (the basic I/O evaluation

software) and of the Software (the I/O table) releases used in each of the I/O boards.

If any of the boards is not installed, the corresponding line will be empty.
