OPERATION TESTING
Although qual ty and operat on of each component are controlled by the factory at the del very, before sale,
eventually, before the final test of the plant, an operat on test ng should be carr ed out.
TEST RUN AFTER THE ASSEMBLY
Clean the gu des before the first test run takes place.
Before the beg nn ng of the run, leave the elevator shaft free from persons and objects.
Before the general test takes place, t s necessary to slowly run through the whole area of act on (w th nspec-
t on control dev ce). After that, ver fy the d stance to be suffic ent for all fasten ng parts (part cularly n the fix ng
area of the gu des and of the governor rope).
If poss ble before that, locate and remove screw project ons and other dangerous narrow po nts.
Subsequently, a stat c funct on test has to be carr ed out:
• operate by hand the overspeed governor: press down the rocker lever;
• dr ve the elevator car
s
lowly
downwards.
The overspeed governor must release the safety gear.
The safety sw tch must release and sw tch off the safety c rcu t of the elevator plant.
W th a slow movement upwards and/or downwards, place the overspeed governor and the satety gear back-
wards.
CONTROL OF ALL OPERATIONS
Subsequently, the release s to be controlled at a nom nal speed, as well as the relat ve safety dev ces.
The control of the release s to be carr ed out as a dynam c funct on test, w th or w thout rated load of the ele-
vator car.
Dur ng test runs, no-one must stay n the elevator car.
Lay down the governor rope nto the test groove and dr ve the elevator car at nom nal speed downwards/up-
wards.
Alternat vely, the overspeed governor can be operated also by hand, by press ng the rocker lever down.
The safety sw tch must release and sw tch off the safety c rcu t of the elevator plant.
W th a slow movement downwards/upwards, br ng the overspeed governor and the brake dev ce (the safety
gear) back aga n.
CONTROL OF THE SAFETY DEVICE FOR ROPE TENSION
The safety sw tch on the tens on we ght w lh counterwe ght s controlled by remov ng the rope of the overspeed
governor from the rope pulley.
When the control s fin shed, the release p n of the safety sw tch must be reset by hand.
