t
an RPM indicator/tachometer operating from one of the
proportional outputs of the SST-2000A/H:
t
an independent meter mounted elsewhere on or near the engine.
2 Wait for the RPM to stabilize.
3 When RPM is stable, select the appropriate set point trim pot .
4 Follow the procedure in Alternate Method 1: steps 1-10.
Alternate Method 3: Adjusting individual set points in high noise
areas
If high ambient noise makes it impossible to hear the relay click:
1 Disconnect the wire from:
t
the center post of the SST-2000A/H set point relay being
adjusted.
t
either one of the other two contacts on the same relay.
[Mark the wires or position them so they can be correctly
reattached.]
2 Connect an ohmmeter to the center terminal of this relay and to
either one of the other terminals of this relay. [If adjusting Relay 1,
connect the ohmmeter to terminals 18 & 17 or 18 & 19.] The
ohmmeter will indicate either a short or an open condition
depending on which terminals are chosen.
3 Adjust the relay as outlined in Method 1: 1-10. When the relay trips,
the ohmmeter will show a short or an open, opposite to the
indication it had before the relay tripped.
4 Reattach the wires to the relays.
5 Repeat the above procedure for other set points to be changed.
