■ Description of Functions
Overload Protection
The G3JA-C is equipped with overload protection. The overload
class can be set to OFF, 10, 15, or 20. Either automatic or manual
mode can be used to reset an overload (trip). Set the trip current to
the rated full-load current of the motor through the overload FLA
setting dial. When an overload fault occurs, the G3JA-C indicates the
overload with a flashing LED indicator and closes the alarm contact.
After an error is detected, the SCR will become hot, and an
overtemperature fault may also be detected. If it is, pushing the reset
button will not reset the system. Resetting will be possible once the
temperature of the SCR has decreased. Wait about two minutes to
allow the SCR to cool (assuming the ambient temperature is normal)
Overtemperature
The G3JA-C monitors the SCR temperature through an internal
thermistor. If the SCR gets too hot, the G3JA-C turns OFF the
output, indicates the overtemperature status with a flashing LED, and
closes the alarm contact. Pushing the reset button will not reset the
system. Resetting will be possible once the temperature of the SCR
has decreased. Wait about two minutes to allow the SCR to cool
(assuming the ambient temperature is normal).
Phase Reversal Protection
When this function is enabled with a DIP switch setting, the G3JA-C
checks phase sequence prior to startup. If the G3JA-C detects a
phase reversal fault in the main circuit power supply, it stops the
starting sequence, indicates the phase reversal with a flashing LED
indicator, and closes the alarm contact.
Phase Loss
The G3JA-C monitors phase loss. If phase loss lasts for two power
supply frequency cycles, the G3JA-C turns OFF the output, indicates
the phase loss with a flashing LED indicator and closes the alarm
contact.
Current Imbalance
The G3JA-C monitors the phase current imbalance. If the imbalance
exceeds the preset limit, the G3JA-C turns OFF the output, indicates
the current imbalance with a flashing LED indicator and closes the
alarm contact.
Shorted SCR
The G3JA-C always checks the SCR for a short circuit before the
starting sequence. If a short circuit is found, the G3JA-C stops the
starting sequence, indicates the short circuit with a flashing LED
indicator, and closes the alarm contact.
