This test proves the pre-trigger inspection stopping points that are used in case of reduced headroom in the pit and
car top escape spaces, see EN81-21. Test is carried out in normal with Door Disable set.
The pre-trigger inspection stopping points can be tested by selecting the “Pre Trig Test” once in Test mode. Move
the car to a terminal floor by placing a top or bottom call. The Limax should trip at the point the pre-trigger stopping
points are set. This will be carried out at inspection speed.
Limax SR1 UCM Test
The SR1 UCM Test allows the SR1 turn off command to be disabled for 10 seconds. This allows the car to leave the
floor by placing a car call with SR1 still turned on, thus testing the Limax3CP UCM feature. The Limax3CP will trip
with the unintended movement fault.
Limax Output Testing
The OC / SR1 and eSGC outputs can be tested / toggled by pressing the relevant buttons.
These tests only work when the car is stationary. An event code 303 "Limax3CP OC Contact Open” is logged
during the OC test this can be reset in the solutions screen.
