Emerson 200I/48-NT5C05C user manual Remote on / OFF control TR, Start up delay DIP switch

42 Functional description

Remote ON / OFF control TR

When a ground signal is applied to the 'Temporary Release' ( TR ) input, the rectifier inhibits its operation and triggers the RFA. When the remote ground signal is discontinued the rectifier returns to normal operation ( see Table 14 ).

Start up delay DIP switch

The rectifier can provide a start-up delay of from 4 seconds up to

120 seconds, with a resolution of 8 seconds and an accuracy of +1 second. Use of this feature is recommended when two or more rectifiers are connected to a common ac input to stagger the inrush currents. A front panel DIP switch can be set to provide the start-up delays listed in Table 13.

4.2.11.Control signals on connector P1

The P1 connector, located at the rear of the rectifier, can be used to verify all the control and alarm signals when troubleshooting the rectifier ( see Table 14 ).

The control inputs are activated by a ground ( BAT RTN ) signal. The alarms, extended by relay contacts, are isolated from each other and the rectifier frame. All contacts are rated 60 V and 0.5 A dc. The normal status of each contact is defined when the rectifier operates normally in the remote sense mode with no alarm. Contacts NC ( normally closed ) and NO ( normally opened ) refer to the de-energized state of their relay coils.
