APPENDIX A – VALVE BLOCK CONNECTOR CHANGE
Starting in January 2009, NORAC is changing the connectors on the boom height control
valve block. The new style valve block will have 2-pin Deutsch connectors on the coils.
The previous models had Hirschman style connectors as shown in Figure 2. The new
style valve blocks and cabling look similar to Figure 25 and Figure 26. Your system may
ship with either style valve block, both are functionally equivalent. The system will
operate properly with either style of connector.
