For stopping, the “Brake Delay” determines time to hold zero speed before the drive is signaled to start the
brake drop sequence. The brake apply timer (#D05) in the drive should be set to a value that allows the
brake to drop before the drive is disabled (Note: Ethos setting “Disable Delay” is not used on E300
systems). Some adjustment of drive gains may be required to achieve good start and stopping (see relevant
drive manual). Confirm start and stopping are smooth and eliminate rollback.
Press: Checklist → Hydraulic Timers
8) Hydraulic Only – Check Start / Stop Timing.
For Hydraulics, pump motor run delays can be adjusted here.
Press: Checklist → Learn Shaft
9) Learn the shaft.
Once the above steps have been checked the panel is ready to learn the shaft. A “shaft learn” procedure
must be carried out before the lift can run at high speed and be entered into service. During the learn,
positions of all door zones and TFR / BFR resets are learnt.
Follow the on screen prompts to perform the shaft learn. The lift will find the bottom floor then perform an up
then down learn sequence at a reduced speed typically 0.25m/s. For a hydraulic lift, the “learn” may be
performed in high or levelling speed, this option can be set in the settings – speed menu. If the lift fails to
learn the reason and help text will be presented on the screen.
Press: Checklist → Floor Teach (only if Limax3CP shaft encoder fitted)
10) Teach floor levels.
Use Emergency Electrical Operation or Inspection Control to move the lift to each floor and teach the floors
positions. See Appendix G for Limax3CP Setup details. This replaces the Learn Shaft sequence above.
Press: Checklist → DZ Stop Distance
11) Checking Stopping is Consistent.
Once the shaft has been learnt the next step is to confirm consistent stopping. Once an acceptable start and
stop has been achieved e.g. no roll back. The stopping point in relation to the floors can be setup. The DZ
Stop Distance screen automatically sets the lift on a learn run into the middle floor from both directions to
calculate the optimum stopping point. Perform this sequence and then check that the lift always stops at the
same point.
Press: Checklist → Profile Adjust
12) Traction Only - Checking Acceleration / Speed.
Use the profile adjust screens to configure the ride profile for Performance / Comfort and Low Energy
Modes. Performance is the maximum designed speed and acceleration rate, this is the default setting. If you
wish to adjust the acceleration or top speed for ride comfort, select the Comfort profile.
The Low Energy profile is the speed and acceleration used whilst on Eco-Mode.
The Emergency Terminal Slowdown thresholds and rates should be adjusted next.
Hydraulic Only - Checking Slowing Distance.
Use the profile adjust screens to configure the slowing distance for deceleration from high speed.
Press: Checklist → ETSD Test
Operation of the Emergency Terminal Slowdown facility may be tested by putting the lift out of step and then
running the lift into a terminal floor, thus mimicking a failure to slow. Follow on screen prompts.
13) Traction Only – Checking Emergency Deceleration Rate.
