92S DUAL POINT WIRING
1. Run power leads to power terminal block TB1 on the
lower left side of the power supply board. Refer to
Figure 7.
2. Run alarm relay wiring for upper (top) level point to TB2
and lower (bottom) level point to TB3.
3. If using malfunction relay, run wiring to upper terminals
marked TB1. Remember, only one malfunction relay is
present for both boards.
4. Auto fill or auto empty can be accomplished with the
use of one control relay.
REMOTE MANUAL SELF-TEST WIRING (91S/92S)
Remote self test is accomplished by connecting remote
test switches to terminal block TB3 for 91S. For 92S, con-
nect remote test switches to TB4 and TB5.
NOTE: The remote manual self test terminal block is not
available on the two-wire loop-powered single and dual
point versions.
1. Use single twisted pair 18-22 AWG wire to connect to
TB3 on single point power supply board, or TB4 and
TB5 for dual point.
2. Determine whether a manual test on a wet condition or
malfunction is desirable. (See page 15.)
DO NOT WIRE SEPARATE 12 VDC POWER SOURCE TO
GENERATE POWER FOR REMOTE PUSH BUTTON SELF
TEST. POWER IS ALREADY AT THE TERMINALS.
3. Run one wire of the twisted pair to the W (wet) or
M (malfunction) position. Run the second wire of the pair
to the blank terminal position marked C (common).
