Overspeed governor EOS
Operating instructions
Step 3:
Check the correct control of the
UCM function:
•
The LED ENM1 of the EOS has to be on, while
the cabine moves
•
The LED ENM1 of the EOS must be off if the
landing door is not locked and the car door is
open (Reversal of the assertion in chapter 2).
•
The LED ENM1 of the EOS must be off as long as
car- and landing doors are both open - even
with parallel circuit Kp closed, if existing.
•
The test described above must be done using
the topmost and the lowermost floor.
Instead of LED ENM1, the state of output MOVE-
MENT LIMITED can be used for check, too (atten-
tion: signal inverted).
If the electronik of the EOS is not seeable
from the controller cabinet (e.g. machine-
roomless elevator or fixation with the elec-
tronic board faced towards a wall) the test
can be also performed via the LEDs in the
EOS Electronic Interface and the related
clamp.
Step 4:
Check the dual channel activation:
The Emergency rescue switch has to be switched to
„O“ Close the doors to have a signal on ENM1 and
ENM2.
Connect one of the two EOS-Inputs ENM1, ENM2 to
GND. After a short period of time (less than one
second) the EOS has to establish a save condition by
opening the safety circuit. This test has to be done
for ENM1 as well as for ENM2
If the electronik of the EOS is not seeable
from the controller cabinet (e.g. machine-
roomless elevator or fixation with the elec-
tronic board faced towards a wall) the test
can be also performed via the LEDs in the
EOS Electronic Interface and the related
clamps.
5.6
Check of the emergency power
supply (UPS)
Before testing the accumuator of the UPS it must
be sufficiently charged. During the test, the eleva-
tor should not be used.
Test procedure:
• Put the elevator and the EOS in a normal oper-
ating condition. The safety circuit has to be
closed (SAFETY and COIL LEDs light up),
• Interrupt the line voltage of the EOS Electronic
Interface with UPS (e.g. by pulling the plug
out of the series terminal). The EOS must
remain operational.
• You can either check if this condition is estab-
lished for 20 minutes or you can check that
the battery voltage has not dropped below 23
volts after 5 minutes .
• After applying line voltage again, the CHARGE
LED should light up for at least 1 minute.
If the test was not successfull the accumu-
lator has to be replaced
