STAMOS S-LS-90, User Manual, Page: 28 / 124

- In this mode, the current assumes a constant, set value. On the other
hand, the voltage changes depending on the load.
4. Overload protection
- Set the switch (6) to “CC” position.
- Following instructions in item 3 connect the terminals (10) and (12) with
wires to regulate the current value. The set value will be the threshold value
of protection activation. Remove wires from terminals.
- Set the switch (6) to “OCP” position. The protection will be activated.
- Set the desired voltage on the output with knob (7). Connect the loads to
output terminals (10) and (12). If the load has a short circuit or other
abnormal behaviour, the output current will increase. If the set value is
exceeded, the protection will cut the power supply to the outputs and an
audible alarm will be activated.
- In order to reset the protection after its activation, disconnect the load,
then set the switch (6) to “CC” position, and then again to “OCP”.
NOTE: When the OCP protection is active, the device cannot operate in the
mode of stabilising the output current.
5. After use, switch the device off using the On/Off button (8), disconnect the
external load and disconnect the device plug from the power source.

Cleaning and maintenance
a) Before cleaning and when the device is not in use, pull the power supply plug.
b) Use only non- corrosive agents for cleaning the surface.
c) After each cleaning, all components should be well dried before the device s
used again.
d) Store the device in a dry and cool place protected from moisture and direct
sunlight.
e) Do not spray the device with a stream of water and do not immerse it in water.
f) Ensure that no water enters through the ventilation openings in the housing.
g) Clean the ventilation openings with a brush and compressed air.
h)
Regularly inspect the device for technical failure and damage.
i) In order to ensure fire protection, replace the fuse only to the specified type
and class.
Fuse replacement
CAUTION! A fuse should be repl aced by a specialist technician.
1. Disconnect the device from the power supply.
2. Disconnect the power supply cable and remove the fuse socket.
3. Replace the fuse with a new one with the same parameters.
4. Assemble the fuse socket.
