• TECH: 05 Ext Control – Magnum has an open protocol policy that allows
certain functions (VAC Dropout, Charge Rate, or Shore Max settings) of
the inverter/charger to be controlled externally—such as with a third
party communications device.
INT: the setting has not changed, even if an external device is in control.
EXT: an external device is controlling the setting—and, the external
device has changed the setting.

Example: When an external device is connected and is changing one of the
controllable functions, the text will change from "INT" to "EXT" to denote that
particular function is being changed. In the example as shown in Figure 3-21
below, the VAC Dropout and Charge Rate settings are not being changed,
but the Shore Max setting is being changed by the external device.

• TECH: 06 SETUP PIN – This menu sets the password (PIN – Personal
Identifi cation Number) and locks/unlocks the ME-RC's SETUP button
menus (as well as the TECH button's 04 Load Defaults menu).
Why should I use the PIN feature? This feature is useful when the
operation of the inverter has been set up by an experienced user or installer.
Restricting access to menus with a password can avoid unauthorized changes
to your settings by inexperienced users.
Setting a PIN
If a PIN has not been set, the SETUP menus are accessible. When you first
enter (press SELECT) the SETUP PIN menu, "PIN = 0000" displays with the
first "0" blinking. "0000" is the default setting when no PIN has been set.
From the PIN = 0000 menu:
1. Rotate the SELECT knob to the desired number (0-9), and then press
SELECT.
2. Repeat Step 1 to set the remaining three digits until the desired PIN
number displays.
3. After pressing the SELECT knob for the last digit, the PIN is set. The
Unlock SETUP menu displays. Rotate the SELECT knob to view the Lock
SETUP and Change PIN menus.
