4 STARTUP ROUTINE
Before carrying out the startup routine, make it clear to yourself what is the difference
between the startup and setup routines.
During the startup routine one checks that the setup routine has been carried out
correctly - i.e. the load sensor has been calibrated and the hoist class has been set
correctly.
4.1 Checking of the calibration and operation of the CU1
1 Check that all electrical connections have been done correctly.
2 Switch the power on.
CU1 runs a self-test program and the version of the program e.g. 'P2.03' is shown on the
display for about 1 second.
CU1 also displays the selected/valid functional options (≥P2.12, see Appendix 6).
3 Check the calibration of the load sensor

and thus, normally, it is not necessary to calibrate it again.
Change the display into the load mode by pressing the blue push-button once (see
Chapter 2.6, 6) and check the calibration of the load sensor:
a) Check that the load display shows ca. 'L 00' when there is no load on the hook.
b) Lift a load as close to the rated load of the hoist as possible (max. 110 %) and
check again the load displayed.

4 Check CU1's ability to prevent hoisting
At this stage you check that the CU1 is able to prevent hoisting; hoisting is prevented in
the beginning of the programming and controlling mode. Lowering is always possible.
