Overspeed governor EOS
Operating instructions
EOS D 300mm
1.1.1
Overspeed
When the elevator accelerates and exceeds contact
speed then the safety circuit is opened. If the car
speed still increases and reaches tripping speed then
the internal governor brake is activated and the
attached safety gear engaged.
1.1.2
Unintended car movement with open
doors (UCM)
The UCM system (Unintended Car Movement)
should prevent from uncontrolled car movements
with open doors according to chapter 9.11 of
EN81-1:1998+A3:2009,
chapter
9.13
of
EN81-2:1998+A3:2009 or chapter 5.6.7 of EN81-
20:2014.
The EOS is used as the detection element, the EOS
Electronic Interface with UPS can be used to provi-
de required functions like the emergency power
supply and the braking element could be a safety
gear, a motor brake, a guide rail brake or a rope
brake. The fulfilling of the standards have to be che-
cked by the operator.
The function to prevent unintended car movement
with open doors can be ordered in several different
types (see „Type“ on the order form and „Type“ on
the type label). „Type 0“ means that there is no UCM
functionality (in this case there is no need to con-
nect ENM1 and ENM2). „Type 1“ EOS is used with a
braking element activated by the governor rope
while „Type 2“ EOS is used with electrically triggered
brakes. See the table on the next page for a detailed
overview.
