Nomenclature
■ Part Names and Functions
Upgraded Models
Production of a new version of the Soft Starter (version 2) with
added functions was started in August 2008. The DIP switch
settings of the new version are different from the previous version.
For details, refer to Upgrades for Version 2 on page 13.
Auxiliary Contacts
The G3JA-C is equipped with two auxiliary contacts as a
standard feature. One contact can be used for fault detection
output. The other one is used to output operating status and
can be set to either Normal or Up-to-speed using the DIP
switch setting at pin number 14.
An optional Auxiliary Contact Block can be added, and DIP
switch pin number 14 can be used to set the operating status to
output (either Normal or Set Speed).
Reset Button
All faults can be reset by pressing the Reset Button or turning
OFF the control power supply. Cooling time may be required
before overload and overtemperature status can be reset.
Note: Test Mode for overload testing will be entered when the

Overload FLA Setting Dial
Use this dial to set the trip current to the rated full-load
current of the motor.
be possible to drive the motor properly.
For a 3-phase, 6-wire motor, use the following formula
to calculate the dial setting.
Set value = Total motor load current/1.73
For example, if the total motor load current is 20 A, the
dial setting is 11.6 A (20 A/1.73).
RUN/FAULT Indicator
The G3JA-C monitors the status before startup and
during operation. One indicator indicates both normal
operation (RUN) and faults (FAULT). If the G3JA-C
detects a fault, it turns OFF the motor and indicates
the fault with a flashing LED indicator.
The G3JA-C monitors the following conditions.
