Input voltage
The input of the charger is protected by means of a fuse. If the fuse needs to be replaced, a
fuse with the same value must always be used for the replacement.
Output voltage
The charger can only be activated if a battery has been connected to it. Without the
presence of a battery no voltage readings will be measured.
Short circuit (output)
The charger is protected from short circuit when no battery is connected, even in the
presence of the mains voltage.
Batteries on the other hand cannot withstand short circuit!
You should for this reason never short circuit the battery. Never short circuit when the
charger is connected to the battery, irrespective of whether the mains voltage is present.
When a battery is short circuited there is a danger that it will explode!!! The charger too will
then incur serious damage.
14-Hour limit
At the charge programs for a stand-alone application, the duration of the charge process is
monitored. Is the duration of the boost phase and equalizing phase more than 14 hours,
then the charging process will be stopped. This way it can be prevented a broken battery
will be charged continuously.
Temperature
The Promax 200 is protected against excess temperatures. At an internal temperature of
more than 40ºC the fan will turn on automatically. When the internal temperature is cooled
down until 35ºC, the fan also stops automatically. If the cooling of the fan isn't enough the
charger will shut down totally. This thermal stop is indicated by an error indication. When the
charger has cooled down until 100ºC it will continue the charging process.
How the temperature protective devices operate will depend strongly on the ambient
temperature.
Level of protection
The indication for the degree of protection contains the character 'IP' (International
Protection) followed by two or three digits that stipulates the conditions that it complies with.
The first digit refers to the class of protection for density, the second digit to the fluid density
and the last digit refers to the impact resistance. The Promax 200 can be assigned IP 205,
which means:
2 = the charger is protected against solid particulate larger than 12mm.
0 = the charger is not protected against water/liquid etc.
5 = the charger can bear a n impact force of 2.00 Joule (2Nm) max.
Important
Protect the charger against moisture, pollution etc. This can be sucked in by the fan en will
damage the charger internally. The cost for this repair is not covered by warranty.
