Each coil igniter will have its own trigger. If using direct fire, a Home signal is needed for
trailing ignition to be generated.

The ignition signals on the IG5 are pulled to ground when activated. These output signals
cannot be used in any circumstances to drive an ignition coil directly: they must drive
some form of igniter. An igniter or ignition module is a device which is capable of switching
the large currents required to charge the coil. The IG5 can be supplied with Ignition
module/s (optional). Two basic types of igniters are available from Haltech. One is the
“Intelligent” type of module such as the Haltech EB023 which has in-built dwell control
(charge time). This type of module is sometimes referred to as a “smart” module. When
using the “intelligent” module, the IG5 Ignition Set-Up page must set Output type to
CONSTANT DUTY. See Chapter 3.2 “Output type”. The most commonly supplied Haltech
“intelligent” igniton module is a Bosch unit mounted on a black anodised aluminium angle
bracket.
The second type of ignition module (igniter), is the “dumb” igniter or constant charge igniter.
THIS TYPE DOES NOT HAVE IN-BUILT DWELL CONTROL. It will not determine
when to switch off the coil charging current by itself. It is essential that the ignition output
type in the Ignition Set-Up page be set to CONSTANT CHARGE BEFORE THIS
MODULE IS PLUGGED IN OR POWER SUPPLIED TO THE IGNITON MODULE AND
COILS. See Chapter 3.2 “Output type”.
Many modules have a similar appearance. Be sure of the type you are using. Incorrect
setting of Ignition Output type or failure to observe the above instructions can damage
the ignition module and/or ignition coil. Damaged ignition components caused be
incorrect set-up will not be replaced by Haltech under warranty.
Tailoring the Ignition Output Signal
The IG5 has the flexibility to tailor the ignition output signals to suit different ignition
systems. The parameters that may be adjusted can be found in the Ignition Setup, area (see
sec.3.2).
Note: if using the haltech bosch type ignition module set the output type to
constant duty.
