Checking the current telescope status
When the ignition is turned on, CCS registers the displayed telescoping sta-
tus from the current status of the telescoping mechanism and the previ-
ously saved locking and unlocking procedures.
Normally, CCS detects differences between the current and the displayed
telescoping and displays the corresponding error message;
in the telescoping mechanism , p. 14 - 17.
If a malfunction results in values being deleted, CCS can no longer calculate
the current telescoping and will not issue an error message.
Risk of damage to the telescoping mechanism!
Before the first telescoping, always check whether the CCS display is
showing the current telescoping.
This prevents the telescoping mechanism from being damaged when
telescoping.
•
Before the first telescoping, compare the telescoping indicated on the
CCS display with the current telescoping.
If the current telescope status is not correctly displayed, enter the current
à
telescope status;
Checks for folded swing-away lattice
The swing-away lattice slews automatically when telescoping.
Risk of damage with a folded swing-away lattice!
Ensure that all connections specified here have been separated and
unlocked before extending.
This prevents the swing-away lattice from failing to swinging and a connec-
tion from being damaged.
