Using an ACLD: Monitoring
Status Description
Active-Absorb Current is actively being diverted to the external load to regulate the bat-
tery bank at the Absorb Volts setting*. The ACLD will remain in the Absorb
stage until the SETUP: 03D Absorb Done Time setting has been satisfi ed.
Active-Bulk If the battery voltage begins rising quickly, the ACLD activates and starts
diverting current in an attempt to keep the voltage from rising above the
Absorb Volts setting*. The ACLD remains in the Bulk stage until the battery
voltage has reached the Absorb Volts setting.
Active-Float Current is actively being diverted to the external load to regulate the battery
bank at the Float Volts setting*. The ACLD remains in this stage unless the
battery voltage falls to a low voltage, which re-initiates another Bulk stage.
Inactive The ACLD is on, but inactive (not actively regulating the battery voltage)
because utility power is connected to the Magnum inverter.
No Comm The ACLD is not communicating with the inverter/remote. This is a normal
status if there is no ACLD connected in the system. If an ACLD is installed,
you may have a bad cable (“ACLD Not Present” displays).
Standby-Absorb The ACLD is not actively diverting current, but the battery voltage has
reached the Absorb Volts setting*. The ACLD remains in the Absorb stage
until the SETUP: 03D Absorb Done Time setting has been satisfi ed, then
goes into the Standby-Float stage.
Standby-Bulk The ACLD is not actively diverting current, but the battery voltage is below
the Absorb Volts setting*. The ACLD remains in the Bulk stage until the
battery voltage has reached the Absorb Volts setting, then goes into the
Standby-Absorb stage.
Standby-Float The ACLD is not actively diverting current, but the battery voltage is now
regulating at the lower fl oat voltage level—after being at the higher absorb
voltage level for the required period—to prevent the battery from being
overcharged. While in this status, if the battery voltage falls to a very low
level, another Bulk/Absorb regulation stage will start.
* – These settings are determined by the battery type settings in the Magnum inverter—which
are communicated to the ACLD.
Table 9-1, ACLD Remote Operational Statuses
9.2.4 ACLD Remote Status Messages
A status message may be an operational or fault message. View the ACLD’s current operating
status using the METER: 06A ACLD Status menu. This menu is useful in determining if the ACLD
is working correctly, or for troubleshooting an ACLD installation.
Note: “Fault statuses” indicate that the ACLD is not operating as intended. Refer to Section 9.3.2
“Resolving ACLD Faults using the ME-ARC” to identify and diagnose the problem.
9.2.4.1 ACLD Remote Statuses
Refer to Table 9-1 for a brief description of the possible ACLD operational statuses that may dis-
play (depending on your remote).
