• TECH: 06 SETUP PIN
– This menu sets the password (PIN – Personal
Identi
fi
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.

•
TECH: 05 Ext Control
– Some functions (
VAC Dropout, Charge Rate,
or
Shore Max
settings) of the inverter/charger can be controlled externally—by
an external device. This display will show
INT
if the setting has not changed,
even if an external device is in control; and show
EXT
if an external device
is controlling the setting—and, the external device has changed the setting.
Figure 3-27, Example: Ext Control Scrolling Screens
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 3-27
below, the
VAC Dropout
and
Charge Rate
settings are not being changed,
but the
Shore Max
setting is being changed by the external device
.
