MAINTENANCE
The unit does not have any internal replaceable or adjustable components available to the
user. Pay attention to the ambient temperature in the room where the unit is operating.
Excessively high temperatures cause faster ageing of the internal components and shorten the
fault-free time of unit operation.
In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with
small amount of detergent or in the case of more significant contamination ethyl or isopropyl
alcohol.
Using any other agents can cause permanent damage to the housing.

SELECTION OF OPERATION MODE
The selection of operation mode can be done by proper jumper settings (see Figure 5.1):
•
externally controlled mode
:
{J1}
open ,
{J2}
open or short
This configuration allows to remote control of the module using it's control input (voltage
7÷12V connected to {
ctrl
} terminal). If control input is not connected, or it's voltage is to low,
module output voltage is turned off - voltage between terminals {
+12V out
} and {
GND
} will
drop to 0V.
•
Stand alone mode
:
{J1}
short,
{J2}
open
This configuration allows stand alone mode of module operation. Module is independent
of external signal
{ ctrl }
. Power supply module is permanently turned on - voltage between
terminals {
+12V
out
} and {
GND
} is about 11.5 V.
