Menu Item Descriptions
976-0043-01-01 7–15
RY11 RY11, when ERROR is selected, is used as an inverter error
detection indicator device to display or sound an alarm when the inverter
AC output is lost. If COOLDOWN is selected, this will allow both
inverters to have a cooldown period when used in a series-stacked
configuration.
23A RY9 VDC Energized
This menu item sets the voltage trip point for relay RY9. When the battery
voltage reaches or exceeds this setting, the relay closes (energizes)
between the N.O. and COM terminals. There is a 2-second time delay on
the reaction of this setting, allowing fast response to rapid voltage
changes in the system. This setting is not temperature compensated when
a BTS is installed.
23B RY9 VDC DeEnergized
This menu item sets the voltage trip point for the auxiliary relay RY9.
When the battery voltage drops to or below this setting for the variable
time period set in menu
23C RY9 Delay At DeEngz. Min , the relay de-
energizes and closes the contacts between the N.C. and COM terminals.
This setting is not temperature compensated when a BTS is installed.
23C RY9 Delay At DeEngz. Min
This menu item sets the delay time period in minutes at which the voltage
level must remain at or below before relay RY9 is deenergized. This is an
“active low” type of control. The relay closes between the N.C. and COM
terminals when the battery voltage falls to or below the level set in menu
23B RY9 VDC DeEnergized for the time period set here.
23D RY10 VDC Energized
This menu item sets the voltage trip point for the auxiliary relay RY10.
When the battery voltage, based on the
04B Battery Comp VDC display,
rises to or above this setting for the time period set in menu 23F RY10
Delay At Engz. Min , the relay energizes and closes the contacts between
the N.O. and COM terminals. This setting is temperature compensated
when the optional BTS is installed.
