CHAPTER 3 | INSTALLATION AND OPERATION
Pins 7 & 8 - Thermal Overload and OC (Overcurrent) Monitor Indicators
The Thermal Overload Indicator (OUT) signal can be used to send a Thermal
message from the CP-16i to an external controller if desired.
The OC (Overcurrent) Monitor Indicator (OUT) signal can be used to send an
OC message from the CP-16i to an external controller if desired.
NOTE:
The THERMAL and OC/CLIP LEDs on the front panel always light to
indicate these conditions.
•
A Thermal Overload Indicator signal is output on Pin 7 on the 10-pin I/O
port. This pin connects to an I/O pin on an external controller.
• An Overcurrent Monitor Indicator signal is output on Pin 8 on the 10-pin
I/O port. This pin connects to an I/O pin on an external controller such.
Pin 9 - On Signal Output / 12V Trigger
On Signal Output
Pin 9 on the 10-pin I/O port provides a continuous 12VDC when the CP-16i
exits Standby Mode for On. When the CP-16i is in Standby mode, Pin 9 voltage
falls to zero. When connected to an external Controller, this pin allows the
Controller to be aware of the On/Off state of the CP-16i.
For Signal Output, Pin 9 connects to an I/O pin on an external controller.
12V Trigger
Pin 9 also functions as a 12V on/off output trigger. In this case, it can be used
to turn on or off other amplifiers, when there are multiple CP-16i system in an
installation.
As a 12V Trigger, Pin 9 connects to Pin 3 (12V Trigger Input) on a downstream
CP-16i.
