Built-in memory systems
The HRVS-DN incorporates 3 memory systems:
EPROM A read-only, non-volatile memory,
containing factory set parameters
(default) that cannot be changed.
EEPROM A read/write, non-volatile memory,
where field adjusted parameters,
statistical and fault data are saved and
stored.
RAM A read/write memory containing
parameters loaded from the
EEPROM which can be changed
from the keypad. These parameters
are stored only as long as Control
Supply is connected.
Memory system operation
1. When Control Supply is switched on, the
RAM is automatically loaded from the
EEPROM and parameters are displayed on the
LCD.
2. Parameters can now be modified from the
keypad (if starter is in one of the operating
modes and software lock is open – Dip Switch
8 open).
3. Start parameters can be modified during
starting
process and will immediately affect the
operation. Example: if Current Limit is set too
low and motor does not accelerate to full
speed, increasing the Current Limit setting will
immediately affect the start process. This
enables selection of the optimal starting
characteristics.
4. After completion of the adjustments,
parameters should be stored in the EEPROM.
Storing of new parameters is possible at the
end of each Mode Page by pressing Store key
after “Store Enable” is displayed on the LCD.
Test Modes:
Three modes of test are available:
1. Test condition where the soft starter is tested
for correct logical operation without Medium
Voltage connected to it.
2. Firing test requires only control voltage
without main voltage.
