3.3. Sequencing.
Electrical loads will turn on sequentially in priority order form 1 to 8 when their respective switch is activated (either
ignition or warning master) and the vehicle is operated in the mode selected for that output (response and/or scene).
loads will sequence off in the reverse order. Priority zero loads will be sequenced on and off but will not shed.
3.4. Shedding.
Electrical loads will be turned off (shed) when the system voltage drops to the shed point for a minimum of 1 minute
(this prevents load shedding due to momentary system power loading such as high current start up devices). Once
shed, loads will remain off for a minimum of 5 minutes and until the unshed voltage is achieved for a minimum of 1
minute. Loads will only shed if the Parking Brake is set and the Load Manage Enable input is active.
3.5. Fast dle.
A fast idle output is activated whenever the system voltage is reduced to 12.8 volts on a 12 volt system or 25.6 volts
on a 24 volt system for a least one minute. The fast idle will remain ON for a minimum of 10 minutes and until 13.0
volts on a 12 volt system or 26 volts on a 24 volt system is achieved. The fast idle output is dependent on the Parking
Brake and Load Manage Enable Input.
Note:
1. This output should only be used as part of a fast idle control system when the proper safety interlocks are
present.
2. The FAST IDLE output will turn off immediately when the Load Manage Enable Input is disengaged.
