Impressive Monitoring Functions

Advanced Alarm Display

(1) A function to blink the backlight upon occurrence of an alarm is provided.
On the conventional models, the display was lit up upon occurrence of an alarm. The new product has a setting function to blink
the backlight upon occurrence of an alarm.
(2) As with the conventional models, the automatic or manual alarm cancel mode can be selected.
(3) As with the conventional models, up to four points of upper and lower limits can be monitored.
(4) The alarm output delay time (alarm mask time) can be set.
Time of alarm output after the maximum value and minimum value is reached can be set.
With this function, alarm output caused by frequency change at start-up current of a motor and start-up of private power
generating facility can be avoided.

Motor Starting Current Mask Function

The use of the motor starting current mask
function for monitoring the motor current can
prevent updating of the maximum value and
alarm output caused by the motor starting
current.
Although the maximum value is not updated,
the current value is displayed.
The starting current mask time can be set in
the range from 1s to 5min.

Note: Set the starting current threshold to a value lower than the lower limit value in consideration of
fluctuations in load current during operation.

<Starting current mask>
The maximum values for current and
power are not updated during the
starting current mask time.
Furthermore, the alarm is not
activated even if the upper limit alarm
value is exceeded.
