Level 5 - Voltage Threshold is where you con-
figure three voltage thresholds used by the
load manager.
SAVE
Save LEVEL 5 - Voltage Threshold settings
and return to Level 5, Load Management, page
16.
CAUTION
The two sets of default voltage thresholds are
set at: 11.8 V, 12.8 V, and 13.8 V; and 11.0V,
11.8V, and 12.8V. DO NOT change the volt-
ages if not necessary. If the thresholds are
changed, the initial defaults are lost and the
new settings replace the default values. The
system does NOT reset to the factory voltage
threshold defaults even when the “Default
Configuration” is selected in Level 1 (see page
7).
Voltage Thresholds
Higher Voltage
The higher voltage threshold programming
can be performed only when key 15 is pressed
and the key 15 LED turns on. Press key 15 to
enable higher voltage threshold program-
ming.
To perform the voltage threshold program-
ming, obtain an adjustable DC power supply
(2A min.) and a voltmeter. Use the power sup-
ply to power the system. Leave all switches
off and adjust the DC power supply output to
14 volts. Enter the programming mode,
LEVEL 5 - Voltage Threshold. Press key 15
to enable voltage threshold programming.
Adjust the DC power supply output to the
High Idle off voltage (default: 13.8V) and
press key 6. Adjust the DC power supply out-
put to the Load Shed Threshold voltage (de-
fault: 12.8V) and press key 5. Adjust the DC
power supply output to the Low Voltage
Alarm Threshold voltage (default: 11.8V) and
press key 4.
The adjustable voltage threshold range is
11 - 15 volts.
The flow chart on page 19 illustrates how the
load manager works in conjunction with volt-
age thresholds.
Press key 9 to save after all voltage thresh-
olds are programmed and return to Level 5 -
Load Management, page 16
Lower Voltage
The lower voltage threshold programming
can be performed only when key 12 is pressed
and the key 12 LED turns on. Press key 12 to
enable lower voltage threshold programming.
To perform the voltage threshold program-
ming, obtain an adjustable DC power supply
(2A min.) and a voltmeter. Use the power sup-
ply to power the system. Leave all switches
off and adjust the DC power supply output to
14 volts. Enter the programming mode,
LEVEL 5 - Voltage Threshold. Press key 15
to enable voltage threshold programming.
Adjust the DC power supply output to the
High Idle off voltage (default: 12.8V) and
press key 6. Adjust the DC power supply out-
put to the Load Shed Threshold voltage (de-
fault: 11.8V) and press key 5. Adjust the DC
power supply output to the Low Voltage
Alarm Threshold voltage (default: 11.0V) and
press key 4.
The adjustable voltage threshold range is
11 - 15 volts.
The flow chart on page 19 illustrates how the
load manager works in conjunction with volt-
age thresholds.
Press key 9 to save after all voltage thresh-
olds are programmed and return to Level 5 -

IMPORTANT
Voltage thresholds dramatically affect the
performance of the load manager. Changing
voltage thresholds from default settings is the
user’s responsibility.
Voltage measurement during programming
voltage thresholds is critical. Voltage MUST
be measured at pin 6 (red wire) and pin 4
(black wire) of the unit’s power cable (see fig-
ure 3-6 in the supplied Hardware Installa-
tion and Maintenance Instructions). Improper
load manager operation will result if voltage
measurements, or settings, are incorrect.
It is strongly recommended that only
trained, or experienced technicians, perform
the voltage threshold settings.
