Parameter:
P 2.3
Unit setting under load
This parameter is used for automatically measuring
and recording the points needed for the precision and
main lift load lines following a defined program.
Adjustment:
Step 1:
enter known load (using DBE)
The other steps are completed from ground
level using the pendant control.
Step 2:
Pro 1 = precision lift setting, zero load
Using the pendant control, the precision lift
must be operated until the motor is shut
down (after about 5 sec.).
The rotating field power is automatically
measured and recorded.
The power recorded is indicated on the dis-
play until the key is released.
Step 3:
Pro 2 = main lift setting, zero load
Using the pendant control, the main lift
must be operated until the motor is shut
down (after about 5 sec.). The rotating field
power is automatically measured and re-
corded.
The power recorded is indicated on the dis-
play until the key is released.
Step 4:
lift known load in precision lift until load is
suspended
This function is enabled for 15 min. If confir-
mation is not given by pressing emergency
shut–down within this time, theLIS–SE swit-
ches back to normal mode. The setting
must then be repeated.
Step 5:
press emergency shut–down when load is
suspended freely; the key must be pressed
for more than 5 sec. After the emergency
shut–down has been reset, the procedure
continues with step 6.
Step 6:
Pro 3 = precision lift setting, known load
Using the pendant control, the precision lift
must be operated. The rotating field power
is automatically measured and recorded.
The power recorded is indicated on the dis-
play until the key is released.
Step 7:
Pro 4 = main lift setting, known load
Using the pendant control, the main lift
must be operated until the motor is shut
down (after about 5 sec.). The rotating field
power is automatically measured and re-
corded.
The power recorded is indicated on the dis-
play until the key is released.
Step 8:
Lift known load in main lift until hoist motor
shuts down. In the case of short hook
paths, this step may also be completed in
precision lift.
Step 9:
Lower load
Step 10:
Compare load with indication onLIS–SE
unit. If the deviation is more than 10 %, the
procedure must be repeated.
Caution!
If any of the steps 2, 3, 6 or 7 is interrupted too
soon by releasing the button (before the hoist
motor is automatically shut down), Err 7 ap-
pears on the display. If you release the key
and press the Enter key, the program will
automatically revert to Step 2. The setting
procedure must be repeated by pressing the
ENTER button.
In case of an insufficient adjustment load,
after step 6 the message Err6 will appear on
the display.
In this case, the adjustment has also to be re-
peated.
Parameter:
P 2.4
Equipment diagnosis
This parameter can be used to switch the outputs of the
LIS–SE manually (main lift, precision lift, Y1 and Y2). In
addition, the signals at inputs E1 to E7, EA can be te-
sted.
The hoist cannot be operated when this parameter is
selected.
To access the diagnosis parameter, enter
CODE no.
1443.
This parameter allows you to perform the following
tests:
-
output relay test
-
part- load switch test
-
input test
To call up the various tests in sequence, press the Enter
key.
