Data acquisition Acquisition of the current gains.
The alarm ends when the acquisition
is done.
Parameter restore
01/03
This warning appears when the
controller restored the default values.
If a CLEAR EEPROM was mode
before the last keyon-recycle,
this warning just means that the
EEPROM was correctly cleared. A
travel demand or a pump request
cancel the alarm. If this alarm
appears at keyon without any
CLEAR EEPROM request by the
operator, there could be a problem
inside the controller.
TH Protection
This alarm occurs when the
temperature of the base plate is
higher than 85°.
Then the maximum current decreases
proportionally with the temperature
increases from 85° up to 105°. At
105° the Current is limited to 0 Amps.
It is necessary to improve the
controller cooling. For realise an
adequately cooling in case of finned
heat sink are important factor
the flux [m3/h] and temperature
[°C] of cooling air. In case of
thermal dissipation realised with
the controller base plate installed
on truck frame it is important the
thickness of frame and the planarity
and roughness of its surface. If
the alarm is signalled when the
controller is cold, the possible
reasons are a thermal sensor failure
or a failure in the logic card. In this
case, it is necessary to replace the
controller.
Thermic sens. KO The output of the controller thermal
sensor is out of range.
This type of fault is not related to
external components; replace the
controller.
