LVD MANUAL RECONNECT ( option )
This option consists of adding a strap identified as “Manual reconnect
jumper” between pins 3 and 9 of TB1 on the NT6C14PA LVD circuit
board (located on the back of the front door of the control and distribution
panel).
When this option is provided, the load will not reconnect automatically
after disconnecting due to a low voltage condition. To reconnect the load
to the system, the LVD BYP/NORM switch must be put in the BYPASS
position and back to the NORMAL position. If this option was furnished,
the additional stamping “MANUAL RECONNECT” should have been
added beside the switch.
Note : If the LVD BYP/NORM switch is left in the BYPASS
position, the LVD will not disconnect if the voltage
decreases below the LVD threshold.
Potentiometers
There are three potentiometers for adjusting the functions described in
Table 28.
Table 28 – Potentiometers
Designation Description
LVD* To adjust the low voltage disconnect threshold
LVR* To adjust the low voltage disconnect reconnect
threshold
HVSD To adjust the global rectifier high voltage shutdown
threshold
Note: * On the NT6C14GC/GN control and distribution panel,
which is not equipped with the LVD feature, the LVD
and LVR potentiometers are still present on the
RPM1000C, but are inactive.
Push-button
The MODE push-button (S1) is used to display the measured value for
each of the eight analog channels on the RPM1000C. Refer to the
RPM1000C user manual listed in Appendix D for additional details on the
MODE push-button.
Fuses
There are eight QFF type fuses for protecting the circuits described in
Table 29.
