14 Input output signal
14.1 Digital Input
The HCL thyristor unit has 2 digital inputs opto-isolated to 24Vdc 5 mA.
You can activate the inputs with the internal supply or with an external source for example the PLC.
14.1.1 Start/Stop (Terminal 3 of M1)
This is the start command (Enable) of the HCL.
If you Remove the Start command the HCL thyristor unit will be stopped and the output will return at
zero.
14.1.2 Configurable Input (Terminal 4 of M1)
This digital input is configured by the parameter
Χδι1
and could perform different functions:
• Enable:
This function forces the output at zero.
•
Feed-Back Selection:
With this function, when you active the input, the feed-back setted in the parameter
Φεεδ
change in
Voltage Feed-Back (V).
• Analog/Digital Setpoint(Local/Remote):
With this function, when you active the input, the setpoint reference change from Analog input to
Digital value in bumpless mode, setted in the parameter
ΣΠ
. The parameter SP is not stored in
memory.
•
Change Firing type:
With this function, when you active the input, the Firing type setted in the parameter
Φιρ
change in
Phase Angle PA.
14.2 Digital Output
(terminal 9-10 of M1)
The HCL thyristor unit has 1 relay output on terminal 9-10 of terminal block M1(Max 500mA, 125Vac).
The functionality of this output cane be setted with the parameter
Χο1
This digital output can be configured in order to activate itself after that one of these alarms occours:
•
HB ,SCR and Current limit alarm are active.
•
SCR and Current limit alarm are active.
•
HB and Current limit alarm are active.
•
Only Current Limit alarm is active.
• HB and SCR alarm are active
•
Only SCR alarm is active.
•
Only HB alarm is active.
See par. “15.3 Relay Jumper configuration on JP3” to set the Relay NC or NO (Normally close-
normalmente open).
