Master Warning, and Parking Brake. The “x” value will be either “H” or “L” to indicate high or low
side polarity.
3.3 PRIORITY Switch
The PRIORITY switch selects the sequence and shed priority level for the selected output. The digital
display will show the current priority as the switch cycles through from “P00” to “P08”. Loads sequence on
in priority from 1 to 8 and they shed off in priority from 8 to 1. Loads set to priority 0 will never shed but
they will sequence on and off.
3.4 ACTIVE Switch
The ACTIVE switch toggles the switch source either ignition or warning master for the selected output.
IGNITION LED: Load output is tied to the Ignition switch.
WARNING MASTER LED: Load output is tied to the Master Warning switch.
3.5 MODE Switch
The MODE switch toggles through the available modes for load management when the Electrical Load
Manager is in programming mode, and it toggles between high side and low side polarity when the
Electrical Load Manager is in polarity adjustment mode.
1) In programming mode the MODE switch toggles though the following states:
RESPONSE LED: Output in ON only when the Parking Brake is NOT set.
SCENE LED: Output is ON only when the Parking brake is set.
BOTH LED: Output is on regardless of the Parking Brake status.
2) In polarity adjustment mode the MODE switch toggles the polarity setting for the selected input or
output between high side and low side polarity.
The MODE switch is also used in conjunction with the USER to place the Electrical Load Manager into
the polarity adjustment mode as described below.
3.6 USER Switch
The USER switch adjust the setpoint voltage for the Variable Trip output on terminal 19. Pressing the
button increases the setpoint in 0.1V increments from 10.5V to 14.5V for a 12 volt system and 21V to 29V
for a 24 volt system. If the setpoint is 13.8V or above on a 12 volt system or 27.6V on a 24 volt system
the output acts as an overvoltage indicator and will turn on when the selected voltage is reached. If the
setpoint voltage is below 13.8 volts for a 12 volt system or 27.6 volts on a 24 volt system the output will
activate when the voltage drops to or below the setpoint.
3.7 STORE Switch
The STORE switch saves the current configuration for the selected load output, alarm output, or system
input when the Electrical Load Manager is in programming or polarity adjustment modes. The display will
indicate that the value has been saved by going blank for 1 second and then return to the load number or
polarity setting being configured.
