ALC II additional features
Auto return, Authorized drive, Flood alarm and High wind speed are examples of features available in the ALC II
system. These functions can be chosen with the system’s normal set-up procedures (page A 12 – A 15).
Auto return
Auto return means that the lift returns to its base location after a certain delay in time. (1 – 7 min. possible to be set). If
value is set to 7 optional time can be set in VirtualPanel service tool. This function is set in GROUP 8 – and will be
activated when time is chosen and set. Base location is normally the base landing (0) and this does not need any further
setting. This can, however be changed in GROUP 10 – 13 to another landing level, if desired.
Example:
Base location on landing level 3.
Set Group 10. VALUE V1 + V2 = landing level 3.
Permission to drive
Permission to drive means for example that a crane operator via a signal to the I/O-card Input 4:4 at the base landing
can address the lift to the base location and also delete all other calls and destinations – until the same person unlocks
the lift. Set this funtcion in GROUP 5, VALUE 1. Base location is normally the base landing (0) and this does not need
any further setting. This can, however be changed in GROUP 10 – 13 to another landing level, if desired.
Fire and gas alarm
A detector signal to the I/O-card Input 4:3 at the base landing will send the lift to the next landing (Stop Next Landing),
delete all other calls and destinations and remains at this landing until the alarm input goes off. Set this function in
GROUP 5, VALUE 1.
Flood alarm
Flood alarm means that a signal from a trottle device automatically addresses the lift to a level where the water cannot
reach. Set this function in GROUP 5, VALUE 4. Decide suitable level and set this in GROUP 10 – 13. Special function
for flood alarm is GROUP 5, VALUE 2 which makes it possible to drive above set level in GROUP 10 – 13.
High wind speed / Low temperature
High wind speed means that the I/O-card in the base can receive a signal from a wind speed meter and then
automatically address the lift to the base location and then also delete all calls and destinations – until the wind speed
will decrease. Set this function in GROUP 7, VALUE 1
Base location is normally the base landing (0) and this does not need any further setting. This can, however be changed
in GROUP 10 – 13 to another landing level.
Low temperature = corresponding function as High wind speed.
Special function for high wind is GROUP 5, VALUE 2 which makes it possible to drive below set level in GROUP 10 –
13.
Digital function can be set in Base. Group 7 V4-V1
Analog
V1 This value is sent to Modbus Cage. (0-1000 = 0-10V.)
Digital On Off
V2 17,5 m/s 16,5 m/s
V1+V2 20,0 m/s 19,0 m/s
V4 22,5 m/s 21,5 m/s
V1+V4 25,0 m/s 23,5 m/s
V2+V4 27,5 m/s 26,0 m/s
V1+V2+V4 30,0 m/s 28,5 m/s
Slipforming
Slipforming means that the lift will stop on temporarily installed cams located on the moveable slipform.
The system receives continuously information where the lift is located on the mast via input to the car CPU’s expansion
unit. The temp. installed cams are monitored by the ordinary normal and final limit cams on the mast.
See page A 38 for programming of the movable top landing for slipforming.
1 instead of 0 at the base landing
This means that the system counts levels, starting from 1, 2, 3 instead of 0,1, 2. (Preferably for constructions hoists
equipped with keypad). If this function is chosen all former programmed levels in the system must be deleted.
Set this in GROUP 6, VALUE 1.
Base location in top
Base location in top means that the base CPU is connected to the top landing instead of the bottom landing.
This is preferable for offshore lifts installed inside the oil rig’s support leg. Set this in GROUP 6, VALUE 2.
