6. Using your fingers, gently pry the S1-S2 connector
block from the compressor.
7. A new S1-S2 wiring harness is shipped with
the CoreSense module. The wiring harness
connector block should be fully inserted on the
two pins.
8. Review the dip switch settings on the CoreSense
module. Dip switch #1 should be “on” or in the
“up” position. All other dip switches should be in
the “off” or “down” position.
9. Route the S1-S2 wire harness so the end of the
harness will not be covered by the module when
it is installed. Install the CoreSense module in
the reverse manner that the Kriwan module was
removed. The module should be installed as
illustrated below.
10. Plug the S1-S2 harness into the 2x2 socket on
the CoreSense module.
11. Connect the previously labeled M1, M2, T1, and
T2 wires to the appropriate terminals on the
CoreSense module.
12. Connect the L1, L2, and L3 phase sensing wires
to the L1, L2, and L3 compressor terminal block
connections. See the compressor terminal cover
wiring diagram for identification of the L1, L2, and
L3 connections on the compressor terminal block.
13. Double check the installation and make sure all
connections are secure. Install the compressor
terminal cover.
14. The module change is complete and the system
can be put back into service.
