ATTENTION!
1. Le chargement au lithium-ion ne nécessite pas de compensation de température. Par conséquent,
n'utilisez pas le capteur de température EVO-BCTS lors du chargement de batteries au lithium-ion.
2. La compensation automatique de température à l'aide du capteur de température EVO-BCTS est conçue
pour les batteries au plomb selon le paramètre de programmation "COMPENSATE" [voir la section
4.4.2.5 du manuel de la télécommande EVO-RC-PLUS]. Lors de la charge en nickel-zinc (Ni-Zn) batteries,
assurez-vous que la valeur du paramètre de programmation "COMPENSATE" est définie sur la base d'une
compensation linéaire approximative pour la batterie Ni-Zn concernée.
4.8 PARALLEL OPERATION WITH EXTERNAL SOLAR CHARGE CONTROLLER
The Battery Charger Section is able to operate in parallel with external Solar Charge Controller with a charging
capacity of up to 50 A. The output of the external charging source is routed through this unit and operates in parallel
with the internal charger. The internal charging current is controlled to ensure that the combined current fed to the
battery does not exceed the programmed value of parameter "BULK CURRENT" [See Section 4.4.2.1 in the EVO-RC-
PLUS Remote Control Manual]. This improves the life of the battery. Please see Section 5.4 for more details.
4.9 COOLING AND OVER TEMPERATURE PROTECTION
4.9.1 Cooling Fans
The unit is cooled by convection and by forced air cooling using 2 variable speed cooling fans. Temperature is
sensed at the Power Transformer and H-Bridge Power Mosfets / Heat Sink. The fans will be switched ON at specified
temperatures measured at the above sense points. The speed of the fans is increased as the temperature rises.
4.9.2 Over Temperature Protection
[Refer to Fault Messages and Troubleshooting Guide at Table 7.1 of EVO-RC-PLUS Remote Control Manual]. The unit
goes to Fault Mode and shuts down due to over temperature sensed at the Main Power Transformer and the Heat Sink for
the Power Mosfets: Fault messages and temperature thresholds for shut down and auto-reset are as follows:
• "Transformer over heat!" : Shut down at 150oC and auto-reset at 80oC
• "Heat sink over heat!" : Shut down at 100oC and auto-reset at 60oC
4.9.3 Automatic Reduction Of Charging Current In Higher Ambient Temperatures
In order to protect against over temperature shut down when operating in higher ambient temperatures of 50C to 60C,
the BULK CURRENT setting [See Section 4.4.2.1 in the EVO-RC-PLUS Remote Control Manual] is automatically reduced as
follows based on temperature sensed at the Power Transformer and at the Heat Sink for the Power Mosfets:
