C E (OC Door Alarm Output)
The internal design of
“
OC door alarm output
”
is that over
‐
current signal is transmitted through an opto
‐
coupler to
give alarms. When over
‐
current is detected on the controller, over
‐
current signal will be immediately sent to diode
of opto
‐
coupler for break over and then transmitted to C, E ports. The client can wire as their own requirements, as
shown in Figure 1, connect to over
‐
current indicator, Figure 2, relay actuation after over
‐
current to give alarms.
Internal wiring diagram of
“
OC door alarm output
”
is shown as follows:
4. S1 S2 S3 Signal Output Terminal:
Such controller has two control modes of external speed potentiometer control and external analogue quantity input.
Description of various terminals is as follows:
•
S1 Terminal: external power+10V
，
•
S2 Terminal: signal input terminal
•
S3 Terminal: GND (grounded).
When external speed potentiometer control is used, S1, S2, S3 terminals shall be connected with external potentiometer as
shown in VI. Driver terminal function diagram to regulate external potentiometer for speed governing
When external analogue quantity input control is used, speed can be controlled through S2 and S3 input, both 0‐
5V and 0‐10V
are OK.
