To initiate warranty coverage on any MOTREC vehicle, the Dealer must complete and return the “Sales/Installation Report” to MOTREC within 30 days after delivery to the Original Retail Purchaser; or within 90 days after the delivery date to the Dealer, which ever occurs first. Failure to follow these procedures will result in considering the warranty coverage effective as of the shipment date from the factory.

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 the utmost importance that theses decals/markings remain unaltered and readable. Else, the sticker or the part baring the marking has to be replaced.

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 BATTERY CHARGER ! WARNING ! Always unplug the AC and DC electrical cords before attempting any repairs to the charger. CHARGER DOES NOT TURN ON: − Dc cord of portable chargers must be disconnected from batteries after every charge to restart; −...
Maintenance ELECTRICAL TROUBLESHOOTING ! WARNING ! Maintenance work must be performed by trained service technicians only. It is the responsibility of the owner of this vehicle to ensure that the services technicians are properly trained, understand and obey the safety rules and guidelines (ANSI B56). All service technicians must read and understand the maintenance warning section in this manual.

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.
Page 21
Maintenance NO MOTION Make sure that the PMC surface is clean and dry; check the terminal areas. Dust Particles or acid contamination, can create current leaks and cause a PMC malfunction. Check F/R switch Turn on the key switch and set to forward. Check voltage between the forward terminal and the –...
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 TROUBLESHOOTING CHART Table 5 PROGRAMMER FAULT EXPLANATION POSSIBLE CAUSE CODE LCD DISPLAY CATEGORY self-test or watchdog fault 1. Controller defective. HW FA I L SA FE 1 - 2 - 3 internal M- short to B- 1.
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.
Curtis Speed Controller PROGRAMMING PARAMETERS – E-290HD, E-348, E-480, E-500, E-660, T-248, T-448 ! WARNING ! The owner of this vehicle shall ensure that the service technicians are qualified, properly trained and obey the safety rules and guidelines in OSHA and ANSI B56 regulations, and in this manual. Before installing and/or programming the PMC, park the vehicle on a flat level surface, lift the wheels off the ground and secure with jack stands of adequate capacity.

OVERVIEW ✓ Fault detection circuitry monitors battery, throttle connections, output transistors, bypass contactor, etc., to prevent runaway conditions ✓ Static return to off (SRO) function requires that forward or reverse selectors be returned to neutral before output is allowed [optional feature] ✓...
WIRING WIRING CONNECTIONS: Low Current Two 1/4" push-on terminals are provided for the throttle inputs. If your controller has a voltage throttle input, there will be only one throttle terminal. A 6-pin low power connector molded into the right side of the controller face provides the low power logic control connections—KSI input, forward/ reverse contactor output, bypass contactor output (optional), emergency reverse (optional), and forward and reverse inputs.
Page 35
WIRING CONNECTIONS: High Current Four tin-plated solid copper bus bars are provided for the high current connec- tions to the battery and motor. Negative connection to battery Positive connection to battery and to motor armature Output to motor field Plug diode to motor armature The cables used for the battery and motor connections must be heavy enough to carry the high current required.
