45. Runtime monitoring is a standard function in every lift control
unit. To check this function, proceed as follows (DIN EN 81, part
1, 12.10 and part 2, 12.12):
Floor selector using magnet switches
a) Stop the car at the bottom landing,
b) Disconnect pulse transmitter from S75 and S77,
c) Enter travel command to top landing ,
d) Car passes by the pulse transmitters without receiving the
necessary signals,
e) After the preset time interval (max. 45 s), the electronic monit-
oring device of the lift control unit automatically interrupts the
travel,
f) Afterwards, the lift control remains blocked for further travels
(see information on LCD),
g) Connect pulse transmitter again to S75 and S77,
h) Operate call button (call/end) and confirm with OK to unblock
the car; alternatively, switch the control unit off and on again.
i) The control unit is now operational again.
46. Floor selector using an absolute encoder
a) Make the car stop at the bottom landing,
b) Reduce the set runtime of the runtime monitoring in the con-
trol system (LC display) corresponding to the travel speed,
c) Enter travel command to top landing,
d) The car does not reach the next encoding point within the
runtime period,
e) After the preset time, the electronic monitoring function of the
lift control automatically interrupts the travel ,
f) Afterwards, the lift control remains blocked for further travels
(see information on LCD),
g) Set the runtime of the runtime monitoring in the control sys-
tem (LC display) to a value corresponding to the travel speed,
h) Operate call button (call/end) and confirm with OK to unblock
the car; alternatively, switch the control unit off and on again.
i) The control unit is now operational again.
47. The creeping correction system of a hydraulically operated lift
remains operational, even if the runtime monitoring has respon-
ded .

48. The motor will be damaged if due to a phase failure (e.g. contact
problems of the travel contactors) the creeping correction system
(re-levelling) remains operational although the runtime monitoring
has responded .
