1.3 MODE SWITCH INSTALLATION
Mode Switch(s) are supplied with the Chronometer, Fuel Computer
and/or Cylinder Analyzer options (a mode switch will be temporarily
needed for calibration of the Fuel Level System option). Refer to
‘FIGURE 1: EPI 800 IND. & SWITCH MOUNTING’.
STEP 1. Once the switch hole has been located and drilled, remove
the paper backing and vinyl front covering from the switch
plate. The switch plate has an adhesive backing to aid in
placement of the plate. Press the plate into position.
STEP 2. Rotate the switch shaft as far counter-clockwise as it will
travel (as viewed facing the shaft). The switch comes with
the lock washer, nut and (optionally) a position locking ring
loosely installed. When removing the nut, if a position locking
ring is installed DO NOT allow it to change position. If you
have accidentally moved the ring, it should be placed back
onto the switch with the tab inserted into the hole between
switch position numbers '9' and '10'. This tab acts as a stop
to only allow switch positions 1 through 9 to be selected.
STEP 3. Insert the switch assembly (switch, optional position locking
ring and lock washer) through the back of the panel. Place
the nut on the switch and finger tighten. Place the knob over
the shaft such that one of the two set screws is
perpendicular to the 'flat' on the shaft. Tighten this set screw.
Now rotate the entire switch assembly until the slotted line on
the knob is aligned with the left lower white line on the switch
plate.
STEP 4. If necessary, carefully remove the knob without disturbing
the current switch assembly location. Now CAREFULLY
tighten the nut (too much force will break the switch). If
necessary, reinstall the knob as before and tighten both set
screws. Verify correct alignment with all switch plate
positions. Plug the switch assembly connector into the small
connector on the appropriate indicator.
