9.3 Functional checks
9.3.1 Multi hoisting
• Set parameter 4-11-1 to “1” and carry out the start-up procedure for the single hoist as described
above in “Start-up”
• Set parameter 4-1-1 back to “n” (where “n” is the number of unit connected to the CAN-bus).
• Check that all parameter values in the parameter group 4-11 “Comm hoist”, are equal in all units.
• Check the load display of all connected hoists via one unit. Refer to chapter “Sum load / solo hoist
load mode” of this manual for instructions.
9.3.2 Multifunction inputs
Check the Multifunction Input 1 operation from the parameter 4-1-1 “MFI1 oper.” and the Multi Function
Input 2 operation from the parameter 4-2-1 “MF2 oper.”.
NU Not used
IntL Intermediate load limit
Tare Load tare
SRope Slack rope by-pass
ST/RT Start and run-time counter
2OLL Second overload limit
Level Levelling limit switch function in common hoisting
CintL Intermediate load limit in common hoisting
CAN CAN bus by-pass
9.3.2.1 Intermediate load limit ”IntL”
• Intermediate load limit is activated when input is not activated.
• When actual load values exceed a limit and the input is not activated then unit work similarly than the
overload situation.
• Check by parameter 4-2-2 the intermediate load limit value.
• Check by parameter 1-2-14 that unit reads the input status.
MFI1 input’s status bit is second bit from the right (XXX1X)
MFI2 input’s status bit is first bit from the right (XXXX1)
9.3.2.2 Tare function ”Tare”
• The control unit must have a button or a switch for this function.
• Hang a load in the hook
• Check the display in tare load mode (yellow LED is illuminated)
• Push the “tare load” switch on the control station
• The value on the display should change to “0.0t”
9.3.2.3 Slack rope by-pass function ”Srope”
• The right action of Slack rope by-bass function checked at same as the slack rope function is tested.
9.3.2.4 Start and run time counter ”ST/RT”
• This function is start and run time counter for trolley and bridge.
• Select the parameter 1-1-10 or 1-1-8.
• Drive trolley (or bridge) several times.
• Check that the value shown with the parameter increases by one after each start.
