Temperature Sensor
(optional)
Table 4.2
Thermal Protection
Status Indicators
The sensor inhibits fast charging outside the operational
temperature
range. Battery sensing is not required if the
batteries are serviced within the specified temperature
range.
The temperature sensor measures the cell temperature
of the battery. The sensor may be part of the battery
assembly or installed externally.
The C4000 is thermally protected by a fan and an
internal thermal cutoff.
System Fault
Fan
The cooling fan engages at 45°C (113°F) and turns off
at 35°C (95°F).
Heat Rail
If the internal heat rail exceed lO°C (158°F), the service
is suspended and resumes when the temperature has
dropped (refer to Table 4.3).
The C4000 performs a number of diagnostic tests when
turned on.
If a system fault occurs during operation, the LEDs may
flash at random and the unit will not respond as usual.
Turn the power off and on again. If the condition
persists, do not attempt to service any batteries.
Turn
the unit off and call for service .
