7.4.1 Run time and start counter for trolley and bridge parameters
Parameter Value Description Note
4-1 MFI1 Accessible with password 4: 8124
4-1-1
MFI1 oper. ST/RT Start counter and run-time counter Counts the amount of times the MFI1 input becomes active (starts)
and the total time the MFI1 input is active (run-time)
Parameter Value Description Note
4-2 MFI2 Accessible with password 4: 8124
4-2-1
MFI2 oper. ST/RT Start counter and run-time counter Counts the amount of times the MFI2 input becomes active (starts)
and the total time the MFI2 input is active (run-time)
Parameter Value Description Note
1 Monitor 1 Accessible with password 1
1-1-7
MFI1 RT “n”h Displays the total time MFI1 has been active
(run-time counter) Read only value
1-1-8
MFI1 ST “n” Displays the amount of times MFI1 has been
activated (starts counter) Read only value
1-1-9
MFI2 RT “n”h Displays the total time MFI2 has been active
(run-time counter) Read only value
1-1-10
MFI2 ST “n” Displays the amount of times MFI1 has been
activated (starts counter) Read only value
7.4.2 Run time and start counter for trolley and bridge connections
A normally open contact of the trolley and/or bridge travel brake contactor is connected to the MFI1
and/or MFI2 input. Without a brake contactor the control command can be duplicated to the MFI1 and/or
MFI2 input.
7.5 Analogue output
The hoist-monitoring unit has one analogue output, which can be used for e.g. a load display or a relay
board that provides certain relay operations according to the load value. The analogue output has a
voltage range of 0…10 VDC. The analogue output can be programmed to represent either the actual
load (or sum load in multi-hoisting), the tared load (or summed tare load in multi-hoisting) or the actual
load of the connected hoist.
7.5.1 Analogue output parameters
Parameter Value Description Note
4-6 AOUT Analogue output parameters Accessible with password 4: 8124
4-6-1
AOUT oper. Act
Tare
Solo Actual load’s values in the output
Tared Load’s values in the output
Solo hoist’s load values in the output,
Parameter 1-2-1 Actual sum load in multi hoisting application.
Tared sum load in multi hoisting application.
Tare function is made for each hoist individual; means tare
command is not transferred to other units via CAN bus. Same
function as in the display.
4-6-2
Zero load 2.00V Analogue output voltage with zero load Adjustable according to the needed voltage of the connected device
when required. *1)
4-6-3
Nom. Load 8.00V Analogue output voltage with rated load. Refer to
parameter 6-4 for the rated load in single hoist
operation
Refer to parameter 4-11-4 for the rated load in
multi-hoist applications Adjustable according to the needed voltage of the connected device
when required. *2)
*1) The zero load voltage should be higher than 0.00V in order to achieve “broken wire protection”
*2) The rated load voltage should be less than 10.0V in order to allow overload indication.
Reliable ranges are from 2V to 8V with large display and from 1V to 9V with other devices e.g. PLC
equipments.
