Curtis 1244 Manual, Rev. E

4 — OEM-SPECIFIED, FACTORY-SET PARAMETERS
When the accessory driver enable is specified “On,” these three drivers are en-
abled. If none of these drivers is required, the accessory driver enable parameter
should be specified as “O.”
Each accessory driver output is rated at 2 amperes and is monitored for
open connection and overcurrent faults. An internal diode provides coil sup-
pression through the coil return output (Pin 9). Wiring for the accessory drivers
is shown in Figure 12, page 18.
When the accessory driver enable is specified “On,” it also enables various
programmable parameters associated with the accessory drivers: the auxiliary
driver dropout delay, the auxiliary coil open check, the reverse signal open check,
the electromagnetic brake dropout delay, and the electromagnetic brake open
check. For more information on these programmable parameters, see Section 3.
Any component can be controlled by any of the accessory outputs provided
its current requirements do not exceed the driver’s 2 amp rating.
e three accessory drivers are enabled or disabled as a group; it is not
possible, for example, to have the electromagnetic brake driver enabled and the
auxiliary driver and reverse signal driver disabled.
