Maintenance Do not try to increase motor speed by changing parameter settings in the speed controller; it can cause accident and severe damage to the motor. SEPEX speed controls are protected by a diode in the power circuit to filter inductive loads in the event of a sudden power interrupt.
Maintenance DECALS AND LABELS ! CAUTION ! The images included in this section depict the decals/markings installed on the vehicle. It is of prior importance that theses decals/markings remain unaltered and readable. Else, the sticker or the part bearing the marking has to be replaced.

Maintenance ACCELERATOR GEAR − Remove the cover. − Backlash between gears must be reduced to a minimum by sliding holder; use locktite 262 to lock the three screws. − When the plastic gear is fully depressed a small backlash must remain between the gears. −...
Maintenance BELT INSTALLATION AND TENSIONING INSTALLATION Adjust the sprockets using a straight edge. Slide up the edge on the larger pulley until it contacts the smaller pulley. Properly adjusted pulleys will provide three points of contact. Properly aligned pulleys will provide four points of contact. Tighten setscrews and recheck alignment. TENSIONING Check the force F required to provide a deflection of 1/8 in.
Maintenance HYDRAULIC BRAKES DRUM BRAKES Remove brake drums and check linings wear; the linings should have a thickness exceeding 1/16" (1.5 mm). Turn the brake adjustment to reduce the clearance between lining and drum but avoid contact or drag when the wheels are turned and the pedal is released. DISC BRAKES Check pad linings for excessive wear;...

Maintenance BATTERY MOUNTING A loose battery increases damaging effects of vibrations and is more prone to short out. BATTERY DISCHARGE LIMIT Discharging below a 20% state of charge cuts down the battery life and the number of cycles available. At 20% state of charge, specific gravity of 6V battery should be 1180; and 1220 for industrial battery. CHARGING AREA −...

Maintenance REVERSE ONLY On a SEPEX motor control, check the forward signal input on the controller. On a series wound motor control, a bad forward contactor is the most probable cause of the problem. Switch to forward and check the voltage on the forward control wire. If not B+, replace the F/R switch. If B+, turn off the key switch, disconnect batteries, disconnect power terminals on the F/R contactors, check the resistance across N.C.

2 — INSTALLATION & WIRING: Controller WIRING: Standard Configuration Figure 3 shows the typical wiring configuration for most applications. The interlock switch is typically a seat switch, tiller switch, or foot switch. Standard Power Wiring Motor armature winding is straightforward, with the armature’s A1 connection going to the controller’s B+ bus bar and the armature’s A2 connection going to the controller’s M- bus bar.
8 — DIAGNOSTICS & TROUBLESHOOTING DIAGNOSTICS AND TROUBLESHOOTING The 1244 controller provides diagnostics information to assist technicians in troubleshooting drive system problems. The diagnostics information can be obtained by observing the appropriate display on the handheld programmer, the fault codes issued by the Status LED, or the fault display driven by the controller’s Fault 1 and Fault 2 outputs.

8 — DIAGNOSTICS & TROUBLESHOOTING LED DIAGNOSTICS A Status LED is built into the 1244 controller. It is visible through a window in the label on top of the controller. This Status LED displays fault codes when there is a problem with the controller or with the inputs to the controller. During normal operation, with no faults present, the Status LED flashes steadily on and off.
