3 Status Indicators Indicate the connection and cutoff
(Red, Green) status for each branch output.
Cut off: Red, Connected: Green (See
note 1.)
4 Tripping Alarm Output Output (transistor: OFF) when the
(+, ) error tripping operation functions.
(See note 2.)
5 Alarm Output (+, ) Output (transistor: OFF) when a set
value for alarm detection is exceeded.
(See note 2.)
6 Over-temperature Output (transistor: OFF) when a set
Output (+, ) value for over-temperature detection
is exceeded. (See note 2.)
7 External Tripping Input The tripping operation can be
(+, ) executed with an externally input
signal.
8 Seven-segment Display Displays measured values and set
(Red) values.
9 Unit Indicators V Lit when the input voltage is being
(Orange) displayed.
A Lit when the output current is being
displayed.
Flashes when the peak output current
is being displayed.
kh Lit when the run time is being
displayed.
C Lit when the temperature is being
displayed.
s Lit when setting the sequence time.
1 to 4 Lit or flashing when displaying branch
output information. (See note 3.)
10 Mode Key Used to change the parameter being
displayed or to reset the peak hold
current value.
11 Up Key Used to move to different setting
modes or to increase a set value.
12 Down Key Used to move to different setting
modes or to decrease a set value.
