ELECTRICAL SYSTEM
INSTALLATION CHECKOUT FOR THE CURTIS SPEED CONTROLLER
SAFETY!
The 1210 controller is inherently a high power device. When working 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.
After installing a controller and before operating the vehicle, carefully complete the following checkout procedure. If you fi nd a problem during the checkout, refer to
the DIAGNOSTICS section of this chapter for further information.
The installation checkout can be conducted with or without the handheld programmer. The checkout procedure is easier with a programmer otherwise observe the
Status LED for codes (located on operator panel wand indicator light). The part number of the handheld programmer is 56409441.
WARNING!
Put the vehicle up on blocks to get the drive wheel off the ground before beginning these tests.
Turn the key switch off and make sure that the throttle is in neutral.
Do not stand, or allow anyone else to stand, directly in front of or behind the vehicle during the tests.
1 Remove electrical panel to access controller then observe LED status light on touch pad operator panel wand indicator light. If a programmer is available,
connect it to the programmer plug-in port.
2 Turn the key switch on. The programmer should “power up” with an initial display. If neither happens, check for continuity in the key switch circuit and controller
ground.
3 If you are using a programmer, put it into the diagnostic mode by pressing the DIAGNOSTICS key. The display should indicate “No Faults Found”. Note: Before
pressing the diagnostics key, wait until model # screen appears, if the throttle is activated prior to this screen appearing the controller will shut down.
• If there is a problem, the LED will fl ash a diagnostic code and the programmer will display a diagnostic message. If you are conducting the checkout without
a programmer, look up the LED diagnostic code in the DIAGNOSTICS section of this chapter (Table 1).
• When the problem has been corrected, it may be necessary to cycle the key or seat switch to clear the fault code.
4 Move the drive paddle to operate the throttle. The motor should begin to turn in the selected direction. If it does not, verify the wiring to the controller, and the
motor. The motor should run proportionally faster with increasing throttle. If not, refer to the DIAGNOSTICS section of this chapter
(Table 1).
5 If you are using a programmer, put it into the test mode by pressing the TEST key. Scroll down to observe the status of the forward, reverse and brake switch.
Cycle each switch in turn, observing the programmer. Each input should show the correct state on the programmer.
6 Take the vehicle off the blocks and drive it in an open area. It should have smooth acceleration and good top speed.
PROGRAMMING VEHICLE SPEED CHANGES
The maximum high-speed M1 (transport) and maximum low speed M2 (scrub) can be changed electronically, using the handheld programmer. To change a
parameter using the programmer, press the PROGRAM key, and scroll down the Program Menu until the desired parameter is the top line of the display. Press the
appropriate CHANGE VALUE key (“up” or “down”) until the desired number is reached. The parameter is now set at the desired value. All programming occurs in
real time. In other words, the parameters can be changed while the vehicle is in operation.
The upper and lower limits of parameters are set at the factory. Some parameters have dependencies on other parameters. When the programmer is being used
to adjust a parameter and a limit is reached, the display will stop changing. To see why the display has stopped changing, press the MORE INFO key. If the limit is
related to another parameter, that information will be displayed; changing the value of the related parameter may allow the original parameter to be adjusted further.
Otherwise, the display simply says “Max Limit” or “Min Limit.”
Use of the programmer is described more fully in the
PROGRAMMER OPERATION section of this chapter.
MAINTENANCE
There are no user-serviceable parts inside the Curtis PMC 1210 controller. 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 periodically, and if a handheld programmer is available, this periodic cleaning provides a good
opportunity to check the controller’s diagnostic history
fi le.
