If the battery voltage is far below normal, the charger will cut the fast charge current and go to trickle charge
mode. The LED will then indicate “error” by a flickering green and orange light.
If the power source input voltage is turned off, the charger will reset. When the power source is turned on again, a
new charge cycle will start. If new batteries are to be connected, the charger must idle for approximately 15
seconds to make sure all parameters in the microprocessor have been reset. When the charger has been reset,
the LED changes to yellow and a new charge cycle can begin.
When the charger is connected to the power source, the LED will be orange for the first few seconds and then
turn to yellow when the initialization and analysis starts.
If a battery is connected, the actual charging will start a few seconds later when the LED changes to orange. After
the start-timer period has run out (the first few minutes of the charge cycle when the -dV detection is disabled), the
LED will be green for approximately eight seconds. This is a signal for testing and service only. When -dV has
been detected, the start of the top-off charge is indicated with a green LED with intermittent yellow flashes.
The LED is green during trickle charge.

TransKeys
WARNING
More than one remote control system may be used at, around, or nearby your operating facility.
Therefore, before inserting a TransKey into an OCU, you must insure the correct coded TransKey
is selected for the desired equipment to be operated.
If the wrong TransKey is inserted into an OCU, other remote controlled equipment located at,
around, or nearby your facility may become operational.
Failure to comply with the above warnings may result in unintended operation of remote controlled
equipment which in turn could result in serious injury or death to personnel and damage to
equipment.
Due to the flexible TransKey concept, it is not uncommon for one OCU to be kept as a spare for multiple cranes or
machines.
Each crane or machine is provided with a unique pair of TransKeys having the same address, this pair of
TransKeys must be inserted into their respective OCU and MCU before carrying out remote control operations.
Once installed, the Transkey may remain in the OCU. However, be sure to remove the Transkey when returning
an OCU for repair so that it can be inserted into the operational OCU.
Two-stage (dual pressure) pushbutton switches are also pre-assigned through TransKey programming for
two-
step
operation.
