SECTION 2 MAINTENANCE SECTION 2 MAINTENANCE
NEVER ADD ACID TO BATTERY!
BATTERIES GENERATE EXPLOSIVE GASES. KEEP
SPARKS AND FLAME AWAY FROM BATTERIES. DO NOT
SMOKE WHILE CHARGING.
2.1 | BATTERY MAINTENANCE
This unit is equipped with deep cycle 12-volt
batteries. The care and maintenance of your
batteries has much to do with how well this unit
functions. Battery wiring and water level should be
checked monthly. Do not overfill. When the cells
are too full, fluid will seep out when charging. The
solution is at its proper strength when the battery
is manufactured. Use distilled water and keep fluid
up to proper level. When required, water should
be added to battery after charging, unless water
level is below the plates.
• Remove side cover to access battery.
• Remove battery caps and check fluid level.
• Fill each cell (if needed) to split ring with
distilled water.
• Reinstall caps.
• Wash all dirt, debris, acid, etc., o battery
whenever corrosion is detected. Use a
solution of 5ml baking soda per 0.95 liters of
warm water.
• Coat terminals with a commercially available
coating.
• Close cabinet and latch in place.
NOTE: The surrounding temperature greatly
aects the power reserve within a battery.
EXAMPLE: A battery that is 100% charged at 80° F
(27°C) drops to 65% at 32°F (0°C). At 0°F (-18°C),
this battery will drop to 40% eciency.
2.2 | CHARGING THE BATTERY
The charger may include an interlock circuit. If so
equipped, the unit will not operate while charging.
To Charge:
• Park the machine on a level surface.
• Plug charger into AC outlet until charged.
• For best battery life, leave the charger plugged
in until machine will be used again. The
charger will maintain the battery charge.

4.3 | CONTROL BOARD DIAGNOSTIC
When using the LED for diagnosis, note that a
DUAL FLASH code is indicated. The LED will flash
on/o a certain number of times, pause o for
a short delay, then flash on/o a second certain
number of times, followed by a much longer
pause o. The sequence will then repeat.
EXAMPLE: The LED flash code 3-2 will look like:
on/o/on/o/on/o-short-delay/on/o/on/o-
long-delay/repeat
FIGURE 6: LED Light Diagnostic Location
LED Code Possible Cause
Fast Flash Control Module is not calibrated, Do not operate unit.
Steady
Unit has just been powered on. You may need to wait for initialization, then re-select function.
Ready to operate, things should be working normally.
A function is selected but the enable trigger is not squeezed.
1-1 The control module is not calibrated. Do not use this unit.
2-1
The key switch selector switch indicate the mode in which the TS100 must operate. If neither
input is active, or if both are active together, the TS100 does not know how to function.
Check key switch and wiring to P15-1 and P12-1.
2-2
A safety feature is locking functions or a switch has failed.
Check that platform is not overloaded, operating on a level surface, and pothole guards deploy.
Check that joystick is neutral when powered on.
Check that joystick trigger is not closed for too long without selecting a function.
Check for failed joystick, selector switches, and up/down switches.
3-x
There is a problem with the drive contactor or valve wiring, or with the motor power wiring;
disconnect connector P9 to see if the problem is caused by drive contactor or valve wiring (if
the fault clears, check for an illegal B+ supply in to P9)
Check motor power wiring; with the drive contactor open the B+ power terminals should be at
10V-15V (significantly lower than B+) If the LED is steady at power-on, and the fault (3-5) occurs
after a delay when attempting to drive or lift, the motor may be stalled and causing an overload
of the TS100 or there is a power wiring error like connecting the B+ cable to a motor stud
LED Code Possible Cause
3-2 Check P9 wiring. One or more signals showing outputs when all should be o.
3-3 Check B+ stud connections on controller. Voltage is too high.
3-4
There is voltage on safe pre-valve supply when there should not be.
Controller may need to be replaced.
3-5
The drive brake current is too high.
Motor overload. Check for a seized motor or for power wiring to motors.
4-x
There is a problem with battery supply, the height and/or pressure sensors, the supply to them,
or the temperature sensor inside the TS100
Check battery supply to EMS inputs P15-1 or P12-1 (relative to the B- stud); the battery supply
should be between 15V and 32V
Check the output from height sensor (P12-12)
4-2
Functions Locked: Board is overheated. Check pump, drive motor wiring.
Problem with controller internal voltage. Controller may need to be replaced.
4-3 Problem with controller internal voltage. Controller may need to be replaced.
4-4
Battery supply is too low or too high.
Make sure batteries are fully charged.
Do not operate while charging.
