4.5.12.3 Resetting the emergency extension system for normal operation
After an emergency extension the system must be reset for normal operation. To
accomplish this you must pull one of the 2 emergency extension handles and
simultaneously switch the toggle switch down. The centre (red) and the lower
green LED will shine.
Switch and handle must be operated until the centre LED stops shining and only
the lower green LED continues shining. The spindle drive will then stop
operating, then let go handle and switch
Thereafter you may retract the landing gear again according to section 4.5.12.1.
4.5.12.4 Part extension and retraction for inspection and servicing
The retraction may be stopped by switching the toggle switch down,
The extension may be stopped by switching the toggle switch up and pressing
simultaneously the press button.
Only the red LED will shine.
For any service work switch off the main switch!
With the procedures described in section 4.5.12.1 you may retract or extend the
landing gear again.
4.5.12.5 Precautionary measures against retracting the landing gear while
on the ground
If the glider is resting on the main landing gear the landing gear should not be
retracted, as retraction will result in damage of the landing gear. To minimise
the risk of such operating error the following safety features have been
incorporated:
1. If the toggle switch is switched up, nothing will happen.
2. If the toggle switch is switched up and the press button is pressed 1 time a
warning tone will sound (only in case a buzzer is installed), otherwise,
nothing will happen.
3. The landing gear will be retracted only if one of the following procedures
will be used:
a) Hold the toggle switch switched up and press the press button 2 times
within 2 seconds.
b) Hold the press button pressed and switch up the toggle switch 2 times
within 2 seconds.
Caution: If you leave the DG-1000 unattended switch off the main switch to
prevent any operating error.
