Using an ACLD: Setup/Monitoring
11.0 Using an ACLD
This section discusses how to con
fi
gure and monitor the Magnum Energy AC Load Diversion controller
(ACLD) using the ME-ARTR router. Refer to your ACLD owner’s manual (PN: 64-0062) for additional
information on setup and operation procedures.
IMPORTANT:
An ACLD must be connected and communicating with the ME-ARTR in order to
monitor its operation. If the ACLD is not communicating or no ACLD is connected, “
No ACLD
Present
” appears when accessing the
METER: 06 ACLD Meters
menu (unless the
TECH: 08 Show
all Menus
menu is set to “
YES
”). Refer to Section 3.2.5 for more info on the
TECH: 08
menu.
11.1 Setting Up the ACLD using the ME-ARTR
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-ARTR
router’s SETUP button to set the amount of time that the battery is in the Absorption stage. This
is accomplished using the router’s
SETUP: 03D Absorb Done Time
menu (see page 37).
Also, when a 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 router’s
SETUP:
02A Search Watts Sensitivity
setting should be turned to
OFF
(see page 26).
11.2 Monitoring the ACLD using the ME-ARTR
This section covers the menus under the ME-ARTR’s METER button that enable you to monitor the
ACLD controller’s operation.
11.2.1 ME-ARTR’s ACLD METER Button Menus
Press the ME-ARTR’s METER button, rotate the SELECT knob to
06 ACLD Meters
, and then press
the SELECT knob to view the following menus.

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 11-1).
Note:
For speci
fi
c information on each operational and fault status, refer to Table 11-1 & Section
11.3.2, respectively.
Info:
This menu is important when determining if the ACLD is working correctly, or for
troubleshooting an ACLD installation. Refer also to Section 11.3.
