Upgrade Controller software.
Controller software may be required to be updated depending on the version installed and the options the lift has.
While we try to make it as simple as possible for software upgrades, unfortunately some EEPROM address’ may be
required to be edited due to additional features being added.
It is recommended that the Service Mechanic that changes this software knows how to change EEPROM settings
and has a definition list for the new version being installed.
Group/Duplex Faults
See Section 3. Group faults
Leveling inhibit. LEV
A leveling failure has been added to stop the lift from re-leveling after 3 attempts of 5 seconds.
See Section5. LCD lift status -
LEV
Run protection timer. RPT
RPT is a fatal error
and can be reset only via a processor POR or Inspection on/off sequence.
See also EEprom setting RPT for more information on RPT sequence.
Lift won’t re-level with doors open
The most common cause for this is the masking circuit.
Note: For this to operate correctly you require one of MSU or MSD inputs but not both. This shall initiate a re-
level, which shall be indicated by the UP or DN and slow speed onboard relays to energize.
Also ensure lift is on operating mode normal.
We must ensure we have a circuit from terminal 16 through to M3. Check your links and status of onboard relays.
If you have the supply to M3 and onboard direction relays up you can then check the neutral side.
The neutral is also switched through a “LR” or “DZ” contact onboard. This switches “N” through to M4.
