Pause Function; Protection From High Input Voltage, Overload And Overheat; 10. Troubleshooting - Real-El STAB SLIM-300 Operation Manual

Operation Manual
Attention! If the AVR is not used for a long time, it is recommended to disconnect the AVR
and all consumer devices from the power supply network.

8. PAUSE FUNCTION

• The Pause mode feature is designed to protect equipment in case of frequent drops of the mains
supply. This is particularly important for consumer appliances with electric motors or compressors.
After power supply has been recovered, the AVR switches on within 6 or 180 seconds, depending
on the "ЗАТРИМКА (Delaying)" button (Увімк./Вимк. (ON/ OFF))  position.
9. PROTECTION FUNCTION AGAINST HIGH AND LOW INPUT VOLTAGE, OVERLOAD AND
OVERHEAT
• The stabilizer is equipped with an circuit overvoltage and undervoltage protection. In the case of
mains voltage deviation over 260 V or below 140 V it turns off the load automatically. At the same
time red LED  illuminates. When the input voltage range returning to 140-260 V the stabilizer
automatically resumes operation.
• In case of overload or short-circuit AVR power switch  will triggered. After elimination overload
cause or short circuits, press AVR power switch  (RESET position), and stabilizer will resume
operation.

10. TROUBLESHOOTING

Problem
The AVR does not start.
The AVR is in operation mode,
but there is no output voltage.
The AVR often produces
clicking sound.
The AVR has disconnected
the load.
If none of the above methods can solve the problem, please seek professional advice at your
nearest service center. Never attempt to repair the product yourself.
Cause
1. The switch is off.
2. There is no power in the
socket.
3. The AVR power switch 
has activated.
The AVR is out of order.
Input voltage is very unstable.
Input voltage is beyond
possible regulation range of
140 – 260 V.

Solution
1. Press the switch once again.
2. Make sure there is electric
power supply.
3. Disconnect part of the load
and switch on the AVR again.
If the fault is not eliminated,
please address to an authorized
service center.
The AVR is regulating output
voltage.
When input voltage is normalized,
the AVR tuns on automatically.
