Operation
5.1
Shutdown
The unit may be shut down by turning the A.C. input and D.C. output breaker Off in any sequence.
NOTE: For the RSM 48/50 and RSM 24/100 Unity Power Factor (UPF) models, the front panel may
be powered up for up to 20 seconds after all power (input and output) is removed from the unit.
5.2
Start-up
To start the unit after a repair or for the first time the procedure as outlined in the initial start-up
section of this manual should be followed. Routine start-up is accomplished by first turning the A.C.
input breaker On and then turning the D.C. output breaker On. This sequence is not critical but it
allows a more controlled charging of the D.C. output filter capacitors.
5.3
Normal Mode
Normal operation of the Module will be in the FLOAT mode. The Module Status OK (green) indica-
tor will be illuminated and, normal mode messages will be displayed (see Figure #1 or Figure #2 ).
5.4
Float/Equalize/Test
When the A.C. power is applied the unit may be operated in the FLOAT, EQUALIZE or TEST
modes. Mode status is indicated by the corresponding message on the LCD display. FLOAT is the
default mode from start up. TEST mode must be manually selected whereas EQUALIZE may be
selected remotely. In the TEST mode voltage steps are approximately 5 mV/step (50mV in test
mode) when adjusting levels. The receipt of a remote equalize signal will put the unit in into equal-
ize and the message REMOTE EQUALIZE will be displayed on the front panel display. Upon re-
moval of the signal, the unit will return to the FLOAT mode.
