Control Circuit Connections
There are two control boards in a Series 22H Vector Control. The Converting Control
Board is used to rectify and process the incoming power. The Power Output Control
Board provides the inverting and power output functions. The keypad is normally
connected to the Power Output Control Board. Each converter board has its own J1
terminal strip. The Power Output Control Board provides the user interface for most
external connections.
Converting Control Board Connections
All necessary connections for the Converting Control Board have been made at the
factory prior to shipment.
The jumper between J1-8 and J1-17 provides the enable signal to allow converter
operation. The jumper between J1-39 and J1-40 pr24VDC from the internal
supply to allow the opto isolated input at J1-8 to operate. These jumpers should remain
installed at all times.
Sometimes it is necessary to troubleshoot the converter section using the isolated opto
outputs. Figure 3-10 shows how to connect external relays to the board to “Sink” or
“Source” the relay current.
The function of each opto output is as follows: (these functions cannot be changed)
