not be moved any more, with the inspection control turned on and the
emergency control switched in and vice versa.
The emergency control functions are essentially the same as those
of the inspection control, but the following safety devices are bridged:
Speed governor,
Buffer contacts,
Emergency limit switches,
Safety gear contact, and
Minimum pressure switch of hydraulically operated lifts.
The car can be driven from the limit switches, if the inspection control
is switched off and the emergency control switched on.
Switching the emergency control deletes all existing calls and dis-
ables the push buttons for cabin calls, landing calls and superior con-
trol functions.
If the control unit is not equipped with an absolute encoder, a cor-
rection travel is required as soon as you have returned to normal
operation. Enter a call for that purpose.
8.8 First Travel with Inspection Controls
The inspection control is used for moving the lift during installation
and maintenance work.
CAUTION!
Pay attention to the safety instructions in section 2 2.
For your personal safety it is important that the switches of emer-
gency control, inspection control and emergency stop as well as but-
tons up and down have been wired into the safety circuit as stipulated
in the wiring diagram.
Emergency stop, door and locking contacts must not be bridged!
This ensures that any interruption of a contact, either emergency,
door or lock, immediately stops the lift.
If the inspection control switch is on, the terminals X5.15, X7.101 and
X12.102 must be dead.
Correction switches S71 and S72 must be fitted at the right decel-
eration point at the terminal landing and switch reliably.
If either switch »Up« or switch »Down« of the inspection control is
activated, the contacts of the safety circuit must be closed.
Travel commands are controlled and monitored by the control sys-
tem bp308. All safety circuit devices remain operational. If any of the
contacts in the safety circuit are interrupted, the lift is shut down
immediately. If a photocell is integrated, terminal X7.53 (door B:
X7.56) must be live.
The inspection control is situated on the roof of the car. Switching
the inspection control on disables automatic door functions and also
