This status may differ for the 787-2861/0108-0020 device. More information is available in the “Signal Output S2 –
Indicators”.
2
The channel is activated again time delayed (170 ms … 500 ms) once the device initialization has concluded.
3
The channel is deactivated automatically in accordance with the given trip curve. The device then switches to Status 5.
4
The status is saved when the input voltage is switched OFF.
5
After a cooling (waiting) period, the channel switches to Status 6.
6
The channel can be re-activated as follows:
• The push and slide switch is pressed twice or
• a pulse (signal 1) is applied at the control input
(see section “Control Input S1”).
The device then switches to Status 1.
The following diagram “General Operating Statuses” visually displays the listed
operating statuses. However, not all operating statuses are shown.
