9KW and 12KW Cabinets: For each module slot that is not occupied by a power module, plug in a
Module Fail Defeat Plug (included with List 90 - Blank Front Panel - when a RSM system is or
-
dered) in the lower socket where the power module would normally plug in.
4.6 Initial Start-up
Repeat this procedure for each module.
Factory settings or last entered settings of a module are stored in non-volatile memory indefinitely.
To adjust the viewing angle a small pocket screw driver or tweaker is recommended.
4.6.1 A.C. Start-up
Apply A.C. power via the feeder breaker, then place the Module's input breaker in the On position.
The display will indicate float mode (FL) output voltage, zero output current and possibly soft start
(SS). Module status indicators should indicate an alarm condition and the Module Fail indicator
should all be lit. The serial number and appropriate alarm messages will also be displayed. See
Figure #3 for menu tree normal mode messages. If the Delay start timer is set to any position
other than zero, the Module will not start until the selected delay has elapsed. The display will
countdown the delay time if set.
4.6.2 Float / Equalize (Initial)
Due to the accuracy of the LCD display the use of an external digital voltmeter connected to the
test jacks is recommend for all voltage settings.
Depress the menu Down key until the ADJUSTMENTS submenu is displayed on the LCD panel.
Depress the Enter/Select key to enter the adjustment mode. See Figure #14 for a typical display
adjustment sequence and syntax. Depress the menu Up/Down keys until the float voltage setting is
displayed. If the level is to be changed depress the Enter/Select key. The display will now read
ADJ^^^^ FLOAT V Using the Up or Down keys adjust the level to the desired setting. Holding a
key down will cause the adjustment to increase or decrease rapidly after approximately 1 second.
Single depressions of a key will cause the output voltage to change in approx 0.005 volt incre
-
ments. Since the LCD display only registers 0.1 volt steps several depressions may be required
when fine adjustments are made. The float voltage can not be set higher than the over-voltage
alarm voltage setting. When the desired level is reached depress the enter/select key to store the
level in memory. The display will step to the EQUALIZE ADJUST menu item.
If no key activity is sensed on the panel for 10 minutes the module will return to normal operation
mode. Entries not confirmed by the enter key will not be recorded. The output voltage may be moni
-
tored via the panel meter or by connecting a D.V.M. (Digital Voltmeter), e/w miniature banana plugs
(0.08" probes), to the front output sense test points.
Repeat the process for reviewing and altering the equalize level. The equalize voltage can not be
set higher than the over-voltage alarm voltage setting.
4.6.3 Current Limit
Prior to closing the output breaker the output current limit setting should be set to the desired level
if different from the factory setting. Check the current setting by scrolling through the adjustment
menu until the current level is displayed. Use the same process described for float setting to adjust
the output current limit point.
