Overspeed governor EOS
Operating instructions
The EOS electronic interface requires a supply volt-
age and a signal which disables the function that
monitors uncontrolled car movement. This signal is
picked up from the safety circuit and is connected
to K1 and K2. If voltage is applied, the UCM moni-
toring function is deactivated. Therefore a car
movement is allowed.
The wiring from the safety circuit to K1 and K2 shall
be made so, that there is no voltage between K1 and
K2 , if the requirements according to EN81-1:1998-
A3:2009, chapter 9.11.1 or EN81-20:2014 chapter
5.6.7.1 are NOT met; i.e the shaft door is locked and
the cabin door is closed.
There shall only be voltage between K1 and
K2, if the shaft door and/or the car door is
locked.
Depending on the design of the safety circuit and
the ordered EOS electronic interface, various wiring
connections shall be provided:
•
Safety circuit without parallel loop to the door
contacts, electronic interface with box.
•
Safety circuit with parallel loop to the door
contacts, electronic interface with box.
•
Safety circuit with or without parallel loop to
the door contacts, electronic interface without
box.
In any case, it is necessary to determine
whether the above condition is met. Usually
it is met by the shown circuits. Nevertheless
the right signal transfer has to be checked in
any case (using LED ENM1 on the EOS)
If the EOS electronic interface is ordered without
the steel box, the wiring shall then be done by your-
self. The signal mentioned above has to be connec-
ted to X4/1 and X4/2. The rest is wired according to
chapter 4.8.2.
If the electronic interface is ordered without
accumulators, an emergency power supply
of 24 VDC has to be connected to X5/1, X5/2
according to the diagram of chapter 4.7.2.
Mind the requirements of the EN81 for the wiring of
the safety circuit between EOS (terminal X7) and the
Electronic Interface (terminals PE, S1a, S1b). These
requirements must be fulfilled for the connection
cable between EOS (terminal X5) and the Electronic
Interface (terminals from +24V to ENM2), too.
A wire with cross section 0,75mm² is recom-
mended for distances between the EOS and
the Electronic interface up to 20m. For lon-
ger distances the cross section has to be
increased (doubled distance means doubled
wire cross section).
It is possible to place only the control ele-
ments further away from the EOS if needed.
In this case no cable dimension change is
necessary.
The contact of the control of emergency electrical
operation, which shall render inoperative state of
the overspeed governor, must bypass the Emergency
Rescue Switch, too (connect contact to terminals
S2a and S2b of the Electronic Interface).
