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.
Charge
time
monitoring
When the charger is set for a ‘stand alone’ application, the duration of the
charging process is monitored. If the boost and equalize phase together take
more than 14 hours, the charging process will be stopped. This way it can be
prevented a broken battery will be charged continuously. But with this feature it
also can become clear that the charge current isn’t in the correct proportion to
the battery capacity (the battery can become damaged when the charge process
takes too long).
Sulfation monitoring
The charger continuously monitors the charging process. If this data shows that
the battery may be sulphated, an error message will appear in the display.
Voltage
drop
compensation
The battery charger automatically compensates for the voltage drop over the
connection cables. Because of this, it’s possible that a voltage reading on the
connection terminals will be higher than the set value. The correct current can
therefore only be measured through the battery poles.
Soft
start
The Promax 200 features a soft start, so that the charger has no influence on
any power users which may be turned on (such as lighting for example). Because
of this the correct charge level can only be indicated 3 min after start-up.
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.
