• Using the second method requires the machine to be running or the key
switch to be in the ON position.
• The Cable Control System will only charge the transmitter battery if the
control cable is connected to the transmitter receptacle and plugged into
the port in the back of the roller.
Charging time
Approximately two hours is required to bring the transmitter battery up to full
charge. This is the most efficient way to use the battery. The transmitter will
operate with a partially charged battery; however, its operating time will be
reduced accordingly.
Note: The charging circuit in the transmitter is self-regulating and limits the
charging current to the battery, so that the battery cannot be overcharged.
Overview
This machine features an ECM with diagnostic and programmable abilities.
The diagnostics are conveyed via alpha-numeric codes displayed on three
LED displays that are viewable through the plastic case of the ECM. These
diagnostic/program abilities include:
• The ability to view the stages of engine start-up.
• The ability to view seven fault conditions and over 35 error codes.
• The ability to lockout or allow engine start after a machine tip-over.
A diagnostic tool, which comes standard with the machine, is used to inter-
face with the ECM.
The ECM displays codes as the machine goes through the start-up se-
quence. These codes are described below.
Note: It is not necessary to enter the diagnostic mode to view these codes.
• Power up delay cycle
• Software version
• Current tip over/roll over mode.
During this state, power is applied to the ECM and decoder but the engine is off.
The ECM is waiting for the start signal to initiate the glow plug cycle.
