MAINTENANCE
There are no user serviceable parts in the Curtis 1230 controller. No attempt
should be made to open, repair, or otherwise modify the controller. Doing
so may damage the controller and will void the warranty.
It is recommended that the controller and connections be kept clean and
dry and that the controller’s diagnostics history file be checked and cleared
periodically.
CLEANING
Periodically cleaning the controller exterior will help protect it against corrosion
and possible electrical control problems created by dirt, grime, and chemicals
that are part of the operating environment and that normally exist in battery
powered systems.
When working around any battery powered system, proper safety
precautions should be taken. These include, but are not limited to: proper
training, wearing eye protection, and avoiding loose clothing and jewelry.
Use the following cleaning procedure for routine maintenance. Never use
a high pressure washer to clean the controller.
1. Remove power by disconnecting the battery.
2. Discharge the capacitors in the controller by connecting a
load (such as a contactor coil) across the controller’s
B+ and
B- terminals.
3. Remove any dirt or corrosion from the power and signal con
-
nector areas. The controller should be wiped clean with a moist
rag. Dry it before reconnecting the battery.
4. Make sure the connections are tight. Refer to Section 2, page
7, for maximum tightening torque specifications for the battery
and motor connections.
DIAGNOSTIC HISTORY
The 1311 handheld programmer or the 1314 PC programming station can
be used to access the controller’s diagnostic history file. The programmer will
read out all the faults the controller has experienced since the last time the
diagnostic history file was cleared. Faults such as contactor faults may be the
result of loose wires; contactor wiring should be carefully checked. Faults such
as overtemperature may be caused by operator habits or by overloading.
After a problem has been diagnosed and corrected, it is a good idea to
clear the diagnostic history file. This allows the controller to accumulate a new
file of faults. By checking the new diagnostic history file at a later date, you can
readily determine whether the problem was indeed fixed.
