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.
