Threshold of Alert output, set by % of the over current threshold (oc). If the load
current is higher than this value, alert output(07-08 contact) is energized
according to the setting of “ALo:XX”.
If the load current is detected, alert output(07-08 contact) is energized. The alert
threshold is no meaning for this operation.
Refer to the Alert Operation Pattern.
If the load current is higher than the alert threshold, alert output(07-08 contact)
repeats open for 1s and close for 1s (flickering), The flickering starts from the
motor starting.
Refer to the Alert Operation Pattern.
If the load current is higher than the alert threshold, alert output(07-08 contact) is
closed (holding) and remains closed until the load current decrease under the
alert threshold. The alert output is blocked during motor starting.
Refer to the Alert Operation Pattern.
If the accumulated running hour is more than the Running Hour threshold,
the alert output repeats close for 1s and open for 1s.
The alert output is used only for under current protection. If this mode is selected,
a trip by an under current fault is signaled through alert output(07-08), instead of
overload trip output(95-96 or 97-98).
Fault reset by a power cycle or by pressing the ESC button.
Fault reset only by pressing the ESC button.
Fault reset by a auto-reset timer,
Setting range of the timer : 0.5sec~20min.
Also the fault can be reset by a power cycle or by ESC button.
The maximum auto-reset number during 30 minutes in auto-reset mode.
The auto-reset counter is stored in the non-volatile memory and is cleared by
pressing ESC button when the counter reaches the limitation.
To disable limitation, select “oFF”. Setting range : oFF~5 times.
In this menu, toggle display, “-trh-” and the accumulated value, is activated.
The accumulation starts from the installation and the user cannot clear the
accumulated value.
This display unit is 1 hour.
In this menu, toggle display, “--rh-” and the accumulated value, is activated The
user can clear the accumulated value by selecting the running hour threshold to
“rh:oFF”. When motor stops
This display unit is 0.1 hour (6 minutes).
By selecting “ALo:to”, the user can get the alert signal through alert output(07-08)
when the accumulated value is more than the running hour threshold.
Threshold for alert output when the user selects “ALo:to”. The unit is 10 hours
and this menu is not displayed when the motor is starting or running.
Setting range : 10~9990 hours, oFF
Modbus slave address.
Range : 1 ~ 247.
Setting for Communication speed
Range : 1.2kbps, 2.4Kbps, 4.8Kbps, 9.6Kbps,19.2Kbps, 38.4Kbps .
Parity setting
Range : odd, even, non.
Duration for communication loss detection.
Displays alarm when no new communication data is received for the duration.
If “oFF” is selected, no monitoring for communication channel is activated.
Setting range : 1~999 sec, oFF
When this menu activated, OL trip signal and enabled EF trip signal is generated
when (3s+ot) expires. The display shows “End” when the test is done.
By pressing ESC, returns to the load current display mode.
This menu is not displayed when the motor is starting or running.
Before (3s+ot) expires, pressing ESC or motor starting or running blocks the test
trip and return to the load current display.
This shows the end of test trip. Test result is stored in the fault record.
