Check the function of the overspeed
contact
Turn contact plate by hand so that contact cam
on Overspeed contact is pushed. If controller is in
normal mode you should not be able to drive the
elevator.
5.4 Functional check
5.4.1 Tripping speed (CS / TS):
The tripping speed must be checked by an author-
ized person.
•
Disconnect the rope clamp from the synchro-
nization.
•
Rotate the governor manually in tripping
direction - Simultaneously measure the speed
on the rope with a speedometer.
•
Accelerate the rotation speed - as slow as pos-
sible - until the speed governor triggers
mechanical.
• Compare the measured value with the values
given in the chapter 4.1.
•
Connect the rope clamp with the synchroniza-
tion lever again after successful testing!
The test must be repeated if the mechani-
cal tripping speed don’t correspond with
the values in chapter 4.1.
The resulted figures may not be exactly (up
to a few percent) the same as written on
the type label, although it is still correct.
Reason:
a) Figure in label is the nominal as ordered (for
tolerances see 4.1).
b) The un-defined acceleration via hand possibly
cause different measuring results.
(The acceleration should be as less as possible,
~0.10m/s²)
5.4.2
Brake force (lifting force) of the
OL35E-NA governor
*
governor force must be 67% greater than safety
gear activation force, according ASME A17.1
Influences what will reduce the brake force:
a) Lubrication inside the brake
b) Worn out of the breaklining (see lifetime of
the brake)
c) Damaged or broken plate spring
Lifetime of the brake:
a) Maximum 250 turns with maximum 15 turns
per test
b) If more than 10 turns per test, the brake of the
governor must cool off for 30 minutes mini-
mum.
