Detects if that portion of Lift is occupied during “UP/DOWN” operation between vehicle floor and the ground. OUTBOARD ROLLSTOP Barrier to prevent the Wheelchair from rolling off of the Platform. Also provides entry/exit ramp for Platform on the ground.
MAINTENANCE SCHEDULE NOTE: The Lift Controller counts the number of cycles & lifts over the lifetime of the Lift. One CYCLE is counted each time the Lift is unfolded from the stowed position to floor level, lowered to the ground, raised to floor level, and then stowed. One LIFT is counted each time the Lift is lowered from floor level to the ground, and raised back to floor level.
CHECKING HYDRAULIC FLUID LEVEL Keep dirt, water and other contaminants from entering the hydraulic system. Before opening the hydraulic fluid reservoir filler cap, drain plug and hydraulic lines, wipe off contaminants that can get in the openings. Also, protect the openings from accidental contamination. 1. Check the Hydraulic Fluid level in Reservoir as follows. With Liftgate stowed, fluid level should be as shown in FIG. 11-1. FILLER CAP 2. If needed, add fluid to the Reservoir as follows.
CHANGING HYDRAULIC FLUID CAUTION Keep dirt, water and other contaminants from entering the hydraulic system. Before opening the hydraulic fluid reservoir filler cap, drain plug and hydraulic lines, clean up contaminants that can get in the openings. Also, protect the openings from accidental contamination. PUMP COVER 1. Unbolt the Pump Cover and remove it from the Lift as shown in FIG. 12-1. SCREWS 11921 Slauson Ave. Santa Fe Springs, CA.
4. Bolt the Reservoir on the Pump. (FIG. 13-1). Reconnect tubes to barb fittings on the Reservoir. 5. Pull out (no threads) Filler Cap (FIG. 122).

TROUBLESHOOTING CONTROLLER DISPLAY READINGS The Controller (FIG. 72-1) may display any of the following readings while the Lift is operating. Some of the readings indicate normal operation, but some indicate trouble with the Lift or vehicle. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 READINGS DISPLAYED HERE LIFT CONTROLLER DISPLAY FIG. 72-1 STOWED* (Stowed Star): Lift is operating normally and the Controller (FIG.
Corrective Actions: 1. Make sure the Stow switch is adjusted correctly. If required, do the STOW SWITCH ADJUSTMENT in this manual. When the platform is resting on the latches, the STOW switch must be closed. 2. If the adjustment does not solve the problem, then check the wire that sends the Lift interlock signal to the vehicle interlock (see ELECTRICAL SYSTEM DIAGRAM). INBRD SW: The Inboard Rollstop is not completey closed and locked in position, or the Inboard Rollstop switch is always open.
CONTROLLER DISPLAY READINGS - Continued MATT ERR: The lift’s Threshhold Plate has pressure on it. There may be a load or occupant on it, or it may need to be adjusted. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 Corrective Actions: 1. Make sure the MAT switch is adjusted correctly. If required, do the MAT SWITCH ADJUSTMENT in this manual. 2.
FOLD SW: The switch state (open or closed) does not match the position of the platform. This reading indicates the “Fold” switch is broken or the wiring is disconnected or damaged. FOLD. (Fold dot): The platform did not pass the “Fold” switch, so the platform is still positioned where the Controller (FIG. 72-1) looks for a pressure reading that indicates an occupant on the platform (50+ lbs).
CONTROLLER DISPLAY READINGS - Continued GRND SW: This is the Controller reading (FIG. 72-1) if the “Ground” switch is not open when the platform is more than 3” off the ground. (Ground switch senses when platform is 3” off the ground.) 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 Corrective action: 1. Go to diagnostic mode on the Controller (see DIAGNOSTICS) and check the “Ground” switch code.
Corrective action: 1. Remove occupant or load from the platform. 2. If there is no occupant or load, go to diagnostic mode on the Controller (see DIAGNOSTICS) and check the hydraulic system pressure reading (PSI). It should be between 170PSI to 230PSI. If reading is not in the range, change the Pressure Transducer. 3. If the Controller (FIG. 72-1) still reads “OCCUPIED”, the platform occupied pressure setting must be changed in the Controller or the Controller must be changed.
DIAGNOSTIC MODE To display Diagnostic readings on the Controller: • If the Platform is positioned above floor level (FIG. 78-1), press the UP button, on the Hand Control (FIG. 78-2), 11 times. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 PLATFORM ABOVE FLOOR LEVEL (STOWED) FIG. 78-1 UP HAND CONTROL FIG. 78-2 • If the Platform is positioned below floor level (FIG. 78-3).

Read the status from left to right for the first set of 8 binary codes. A “1” means open and “0” is closed. The first 4 of 8 status numbers will always read 1 (i.e. 11110101) (TABLE 80-1).
