INPUT AND OUTPUT NOT SYNCHRONIZED

Digital Energy™ LP Series

The output converter frequency is not synchronized to the utility (input) frequency. In this situation the automatic bypass switch is not able to transfer the load from output converter to bypass and reverse: automatic bypass operation is inhibited: if for whatever reason the output converter is unable to deliver the required output, output power is lost. (see section 3.5).

Synchronization is only possible if the utility frequency remains within certain limits (see chapter 10).

The output will be switched off by a remote command (RS232/SNMP). The second line indicates the time until shutdown.

The output is switched off by a remote command (RS232/SNMP). The second line indicates the time until wake-up.

The output is switched off by the 'no-load shutdown' feature: no input voltage and load <2%. If the input voltage is restored, the output will be available again. See also section 5.5.1

The wire on connector J3 pin 3-4 (rear panel, plug-in card 12) is interrupted. The output is no longer available. To restart the unit, restore the connection and turn the on/off switch (rear panel, 7) off and on again.

When the default screen is displayed you can enter the first service screen by depressing the keys 'down' (2) and 'Enter/Reset' (3) simultaneously for approx. 1 second. Using the 'up' (4) and 'down' (2) keys you can scroll through several service screens.
