Using an ACLD: Setup/Monitoring
9.0 Using an ACLD
This section discusses how to confi gure and monitor Magnum’s AC Load Diversion controller
(ACLD) using the ME-ARC remote. Refer to your ACLD owner’s manual (PN: 64-0062) for addi-
tional information on setup and operation procedures.
IMPORTANT: An ACLD must be connected and communicating with the ME-ARC in order to
monitor its operation. If the ACLD is not communicating or no ACLD is connected, “No ACLD Pres-
ent” appears when accessing the METER: 06 ACLD Meters menu (unless the TECH: 07 Show all
Menus menu is set to “Yes”). Refer to Section 3.2.5 for more information on the TECH: 07 menu.
9.1 Setting Up the ACLD using the ME-ARC
During Standby and Active modes, the ACLD controller is in charge of monitoring and regulating the
battery voltage and determining the battery’s absorption charge time. Use the ME-ARC remote’s
SETUP button to set the amount of time that the battery will be in the Absorption stage. This is
accomplished using the ARC’s SETUP: 03D Absorb Done Time menu (see page 31).
Also, when the Magnum inverter is fi rst turned on, its automatic Search feature is enabled. To
ensure the transfer from Inactive to Standby/Active mode occurs smoothly, the ARC’s SETUP:
02A Search Watts setting should be turned to OFF (see page 20).
9.2 Monitoring the ACLD using the ME-ARC
This section covers the menus under the ME-ARC’s METER button that enable you to monitor the
ACLD controller’s operation.
9.2.1 ME-ARC Remote’s ACLD METER Button Menus
Press the ME-ARC’s METER button, rotate the SELECT knob to 06 ACLD Meters, and then press
SELECT to view the following menus.
METER: 06A ACLD Status
This read-only menu displays the ACLD’s current status. These statuses (listed below) identify
what state the ACLD is currently in—only one displays at a time (see also Figure 9-1).
Note: For specifi c information on each operational and fault status, refer to Table 9-1 & Section
9.3.2, respectively.
Info: This menu is important when determining if the ACLD is working correctly, or for
troubleshooting an ACLD installation. Refer also to Section 9.3.
Operational Status:
• Active - Absorb
• Active - Bulk
• Active - Float
• Inactive
• No Comm (ACLD not present)
• Standby - Absorb
• Standby - Bulk
• Standby - Float
• Desat Fault
• High Current
• High VAC In
Fault Status:
• No Load
• Output Short
• Overcurrent
• Overtemp
METER: 06B ACLD Power Diverted
This read-only menu displays the amount of current diverted to the loads connected to the ACLD.
METER: 06C ACLD Temp
This read-only menu displays the ACLD’s internal temperature.
METER: 06D Target Volts
This read-only menu displays the voltage regulation set-point after it has been compensated
based on the battery temperature sensor (BTS) reading shown.
METER: 06E ACLD Version
This read-only menu displays the software version of the ACLD controller.
