MAINTENANCE
There are no user-serviceable parts inside Curtis controllers. No attempt should
be made to open the controller. Opening the controller may damage it and will
void the warranty.
However, it is recommended that the controller exterior be cleaned periodi-
cally, and—if a handheld programmer is available—this periodic cleaning pro-
vides a good opportunity to check the controller’s diagnostic history file.
The 1214-/15-/19-8 controller is inherently a high power device. When work-
ing around any battery powered vehicle, proper safety precautions should be
taken. These include, but are not limited to: proper training, wearing eye
protection, avoiding loose clothing and jewelry, and using insulated wrenches.
CLEANING
Although the 1214-/15-/19-8 controller requires virtually no maintenance when
properly installed, the following minor maintenance is recommended in certain
applications.
1. Remove power by disconnecting the battery.
2. Discharge the capacitors in the controller by connecting a load (such as
a contactor coil or a horn) across the controller’s B+ and B- terminals.
3. Remove any dirt or corrosion from the bus bar area. The controller
should be wiped clean with a moist rag. Allow it to dry before recon-
necting the battery.
4. Make sure the connections to the bus bars are tight. Use two wrenches
for this task in order to avoid stressing the bus bars; the wrenches should
be well insulated.
DIAGNOSTIC HISTORY
The handheld programmer can be used to access the controller’s diagnostic
history file. Connect the programmer, press the MORE INFO key, and then—while
continuing to hold the MORE INFO key—press the DIAGNOSTICS key. The program-
mer will read out all the faults that the controller has experienced since the last
