Testing all functions
Refer to “
Section 8.10 Acceptance inspec-
tions and tests” of the ASME A17.1
.
In the following the check of electrical tripping,
the release of the safety gear as well as the verifi-
cation of the tripping speed is described.
The operation of the electrical tripping (CS)
must be checked in both directions of
movement.
Check of tripping speed (CS / TS):
•
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
possible - until the speed governor triggers
electrical and 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 electrical tripping must be checked in
up direction too - the governor triggers
only
electrically in up direction.
The resulted figures may not be exactly (up
to a few percent) the same as 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 acceler-
ation should be as less as possible (~0.10m/s²)
The governor must be replaced if the
measured tripping speeds don’t correspond
roughly with the values in chapter 4.1.
Adjustments on site are not allowed!
Trigger testing is a
dynamic functions test
that
can be carried out with or without the car rated
load.
No one should be in the car when carrying
out test runs or functions tests!
After each test, the contact plate must be
reset by hand or by the use of the remote
control.
Check of the electrical tripping (CS):
•
Let the car ascent at rated speed
•
Trigger the speed governor manually
(by pushing a screwdriver trough the hole on
the back of the governor stand) or by the use
of the remote control
The overspeed governor must stop the elevator
electrically by interrupting the safety circuit.
Check of the mechanical tripping (TS):
•
Let the car descend at rated speed
•
Trigger the speed governor manually
(by pushing a screwdriver trough the hole on
the back of the governor stand) or by the use
of the remote control
The overspeed governor must stop the elevator
mechanical by actuating the safety gear.
