10.3. Appendix 3. Adjusting limits for Fail-safe Mode
The standard
SECTOR II
is supplied in Fail-safe Mode, meaning that the boom can be
moved from the raised or lowered positions without requiring a manual override.
Alternatively, the operator can be configured so that, when mains power is present, the
boom pole cannot be lifted or forced down but, in the event of a power-failure, the pole
can be operated by hand. This can be set in the menu system (Menu 5.1).
In certain circumstances when the
SECTOR II
needs to be in ‘Locked Mode’, (meaning
that the boom pole cannot be raised, or lowered, by hand), it will require use of the 6mm
Allen key (provided) in the manual override slot to raise, or lower, the boom pole.
Ensure all power to the SECTOR II is OFF by switching off both the AC
and DC isolator switches.
To convert the locking stops from Fail-safe Mode to Lock Mode, the stopper screw needs
to be unscrewed using a T30 TORX extended length bit, a 1/4” ratchet spanner and
appropriate ratchet adaptor. Rotate the locking stop to the locked position, insert the
screw and tighten using the aforementioned tools.
The following figures show the endstops in their locked and unlocked (fail-safe) positions
respectively.
