Note:
1. You are allowed to change the Analog Programming Settings only when the
device is turned off.
2. External simulation programming only determines the output related quantity by
external signal when the corresponding function item is opened, otherwise the
device setting can still be controlled by man-machine interface or remote
communication.
3. Compound port "I-Set" input analog programming signal, which is valid for
device source and load control current and set the same value; "P-Set" is valid for
both source and load control power, and the set value is the same.
3.8.3.External control function
FTB9000 composite signal port provides a trigger signal input port "Inhibit", which is
connected as shown below
：
Photo 3- 11Trigger signal connection
This port receives a 5V TTL level signal, which is valid at low level. You can use a
physical switch such as Figure 3-11 Trigger Signal Connection or a 0 to 5V signal source
to trigger the signal. Closed or 0V is a low level and disconnected or 5V is a high level.
The response time of the port is about 20ms, and it can be set to Trigger, Toggle and Hold.
For the specific electrical performance, please refer to "Description of Composite Signal
Function in Table 2-4".
