Important Notes for Installer
1. Individually program each lamp to the desired flash pattern as shown in the
"Programming mode" instructions.
2. Connect lamps as per wiring diagram A
It is recommended that the earth returns should be connected using low impedance wiring with no other significant ground
currents in the ground wiring. It is not recommended to use the vehicle chassis for connecting the ground and ground loops
must be avoided.
It is possible by adjusting the offset during the programming phase to ensure that all flash patterns can be syncronised
together or opposed. The offset required to achieve this will be different depending on which flash pattern the user has chosen
as the default. During
of the programming instructions the flash pattern timing can be off-set by multiples of 250ms (90°)
by connecting the flash (blue) cable to positive (+). (see fig 2. example)
By default all blue & green lamps will start with a 250ms delay to the red & amber lamps. This feature can also be used to
create a "chase" function where by 4 lamps can be programmed to flash one after the other in sequence.
(it is recommended that the same flash pattern be selected for all lamps to be
syncronised)

Introduction
Electromagnetic Compatibility (EMC)
Electric Welding
Multivolt LED signal and marker lamps offer many advantages over conventional bulb lamps. Significantly reduced power
consumption, ultra long life and high tolerance to shock and vibration make the LED lamps the ideal choice for the commercial
operator, who values the economic cost of ownership versus the initial purchase price.
This Multivolt LED lamp is an electronic device. The electrical circuits contain components that suppress possible interference,
both emission as well as susceptibility, to the limits prescribed in the European Union Directive 95/54 EC.
To avoid false signals or interference, it is standard practice that sensitive instrumentation such as ABS and Tachometers etc.
are provided with direct earths.
Electric Welding may damage the LED lamps. For LED lamps, Hella recommends the negative connection to be wired isolated
from the vehicle chassis. If the lamp uses the chassis as the earth return it is recommended that this earth return is
disconnected during electric welding.
