2.2.3 Control switch and fuses
Main switch Q1
The main switch is used to switch the entire lift system (including the frequency inverter) on and off.
The UPS emergency power supply features its own internal power source (batteries). That is why the FST con-
troller, emergency current monitor and brake control components can be live even if the main switch is switched
off.
To switch off power to the entire installation, excluding the feed terminals and an optional UPS if necessary,
control switch S1000 must be switched off in addition to the main switch.
Shaft light K72
Surge relay K72 is used to control the shaft light via shaft light button S72 (on the car and in the shaft pit).
Switching the shaft light from the control unit is done by actuating the control button directly on relay K72.
Car light S14
Control switch S14 is used to switch off the car light and shut down the installation.
After control switch S14 is switched off, shut down occurs as follows:
› FST display shows REMOTE SHUTDOWN
› Car is sent to a adjustable remote shutdown oor (setting under HAUPTMENUE / Konfig / Fernabsch.
Etage)
› Car door opens for the set open hold time (setting under HAUPTMENUE / Tueren / Tueren Selektiv /
Offenhaltezeit) and then closes
› Car lighting is switched off and the installation remains shut down until S14 is switched on again
S1000 UPS ON/OFF
Control switch S1000 is used to switch the emergency power supply on and off.
The UPS features its own internal power source (batteries). To prevent the batteries from discharging during
normal operation, the following must be observed:
Only switch on emergency power supply via control switch S1000 when needed. Before leaving the installation,
switch off the emergency power supply via control switch S1000 without fail.
Opening brake S140/S141
Control buttons S140/S141 are used to manually release brake circuits A and B of the drive. They can be used
to implement the "freeing of persons", "checking the dual-circuit" and "checking the brake release monitoring
system" functions.
More information can be found in chapter 3.1 "Freeing of persons", 3.2 "Checking the dual-circuit drive brake
system" and 3.4 "Checking the brake release monitoring system".
F4 controller
The RCBO of controller F4 secures the entire safety circuit as well as power supply G1 for the FST circuit board
with 6A by default.

The wiring protection of the safety circuit is performed by circuit breaker F4.1 as well as the RCBO F4. This is
2A by default.
F5 door drive
The circuit breaker of door drive F5 secures the door drive with 6A by default.
F9 shaft light
The RCBO of shaft light F9 secures the shaft light with 10A by default.
