Operating instructions
5.1 Static functions test
The
static functions test
must be carried
out to check the two-channel functionality:
•
Power-on the EOS and apply RESET
signal if necessary:
See also chapter 4.3!
The LEDs are as follows:
“POWER”
˜
LED on
“CHANGE UNIT”
™
LED off
“TTS1”
™
LED off
“TTS2”
™
LED off
“SAFETY”
˜
LED on
“COIL”
˜
LED on
•
TRIP-input on: Coil1 is released and activates
tripping mechanism. Remove TRIP signal.
“SAFETY”
™
LED off
“COIL”

Remote tripping (TRIP) releases just one coil.
Therefore this sequence has to be per-
formed twice.
•
Move the car
slowly
(e.g. service
drive) in direction of safety gear- and governor-
activation until the safety gears have stopped
the car movement. Check that the safety circuit
is opened now.
•
Drive the car out of safety gears slowly (e.g.
with service speed; vertical car distance
~5 cm;
stop then
).
•
RESET-input on (momentary switch): Coils are
powered

The safety circuit is closed now and the gover-
nor wheel free to move. LED’s indication is like
after power-on.
The governors tripping speed (as marked on the
label) can be checked if the governor’s rope is
released from the synchronisation linkage and is free
to accelerate downwards. The speed can be meas-
ured by a tachometer.
Make sure that the governor rope is attached to the
synchronisation linkage before any functions test
and before the elevator is put into service!
