16. In-built motor protection switch, over-current release, current-op-
erated circuit breaker etc. have been set at factory and have to
be individually adapted to the appliances connected by you while
commissioning the control system .
17. According to the respective operation instructions, the following
wiring instructions are to be followed:
Conductor N (N) to terminal 9 of bp308.
Conductor N (N) to terminal 14 of bp308.
18. According to VDE-rules and TRA 200, the signal voltage (minus
24 V DC) is to be connected to the protective earth conductor
(PE) of the mains supply .
- Terminal 100 (minus 24 V DC) of bp308 is to be connected to
the PE terminal in the control unit, thus avoiding a floating net-
work and making it possible to recognize an earth leakage of the
signal voltage (+24 V DC) at once .
- Transformers are connected to the earth at the secondary side
(e.g. special voltage of brake or valve) thus avoiding a floating
network and making it possible to recognize an earth leakage of
the secondary voltage at once.
19. Terminals 20A and 20C (+24 V DC max. 2.2 A) of bp308 are
monitored with regard to overload and short-circuit. Overload is
signalised by the LCD.
20. Safety circuit and query-unit of bp308 are fused at max. 1 A.
21. Pay attention to the control pulse-diagram. Presentation of the
pulse-lugs is not true to scale. It is just a schematical diagram .
22. Arrangement of the shut-down points in the landing area (landing
level zone) is to be observed precisely.
23. Signals from the pulse-generator and flush-level switches can be
monitored on the LC display in the service-menu, sub-menu well
signals, not only in the travel mode but also in the inspection con-
trol mode or emergency control mode.
24. It is possible to keep the car door closed at the landings during
maintenance and service activities. See service-menu, sub-menu
maintenance, on the LCD.
25. During checks, the car can be driven to the top or bottom landing
by activating the »Call« switch:
Switch up: car travels to top landing,
Switch down: car travels to bottom landing.
