Introduction

Normally  maintenance  and  installation  of  VP-1405A  end  without
problem if engineer consider terms and conditions in this manual. But
sometimes you may encounter to some trouble that normally caused
device not operate or has malfunction.
In this case before contact to Veesta World Company support center,
review  this  chapter.  You  may  found  common  problems  that  may
encounter to them. These common problems normally are from your
missed a condition mentioned in this manual. So this chapter not only
helps  you  to  find  the  problem,  but  also  let  you  have  a  check  list  to
installation of module VP-1405A.

Please pay attention that if you not follow terms and conditions in this
manual any damage to product will not be in guarantee terms.

Table 8-1: VP-1405A Troubleshooting

Possible Problem

Possible Cause

Possible Solution

The module has no
indication after the
control power supply is
imposed.

The mains supply fails to
be imposed on the
module.

Check if the correct working
voltage has been imposed on
the L/+ and N/- terminals of the
module.

Module dose not work
no indicator lights turn
on

No AC power
AC input socket fuse
blown

Check AC connections are
correct. Replace with correct
AC fuse by qualified electrician

Output short circuit

Check DC connections
between charger and battery

Over temperature
protection triggered

Check air intake vent at bottom
of charger is blocked or not.
Check charger ambient
ventilation .

No DC Output

Reverse battery polarity

Check for correct polarity,
