Checks before
starting work
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;
à Malfunctions
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.
• 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
telescope status;
à Current telescoping, p. 10 - 101.
Checks for folded swing-away lattice
The swing-away lattice slews automatically when telescoping.
• Check that the driver (1) is unlocked and that
the connection (2) is separated;
à Operating Instructions Lattice Extension.
S
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.
S
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.
