During this time the “CLUTCH ENGAGED”
symbol will illuminate to indicate that the
clutch is engaging. See sketch below.
Clutch Disengagement
To disengage the clutch, push the
“Engage/Disengage Button” and the clutch
will immediately disengage. The “CLUTCH
ENGAGED” symbol will not be illuminated.
FAULT – RPM TOO HIGH, while
attempting to engage
The engine rpm must be below
1100 rpm to allow the clutch to engage. If
the engine speed is above this limit while
attempting to engage the clutch, the “RPM
TOO HIGH” symbol will illuminate. See
sketch below. Reduce engine speed
below 1100 rpm and the light will turn off.
Reattempt clutch engagement.
If, while the clutch is in the process of
engaging (“bumping”), the operator
intentionally increases engine speed, the
engagement process will abort. The
“CLUTCH ENGAGED” symbol will turn off
and the “RPM TOO HIGH” symbol will
FLASH to indicate that the engine speed
was intentionally increased while the clutch
was still “bumping”. (This is considered an
aborted startup attempt).
If the operator keeps the speed above
1100 rpm and re-attempts clutch
engagement, then the “RPM TOO HIGH”
symbol will turn on SOLID, indicating that
the clutch is still over-speed. If the
operator then lowers the speed below 1100
rpm then “RPM TOO HIGH” symbol will
turn off.
FAULT – RPM TOO HIGH, while
attempting to disengage
The engine rpm must be below
1200 rpm to allow the clutch to disengage.
If the engine speed is above this limit while
attempting to disengage the clutch, the
“RPM TOO HIGH” symbol will illuminate.
See sketch below. Reduce engine speed
below 1200 rpm and the light will turn off.
Reattempt clutch disengagement.
FAULT – TIMED LOCKOUT
The controller will allow 3 failed
clutch startup attempts in a row.
After the 3
rd
failed clutch startup attempt,
the controller will prevent the clutch from
being engaged for 10 minutes. While the
clutch is in lockout, the “TIMED
LOCKOUT” symbol will illuminate to
indicate that the clutch is in lockout and
cannot be engaged. See sketch below.
