Functional options
The CU1's functional options are switched ON or OFF by level 2 passwords. By
entering password 1-000 (>P2.12) CU1 displays the selected options (e.g. 'Opt 1').
Option 1; Low voltage detector
Option 1; Low voltage detectorOption 1; Low voltage detector
Option 1; Low voltage detector (> P2.12) [Password 2-865]
This option can be used in the case that an Err_3-situation occurs during
starting of the hoisting machinery because of voltage drop in power supply
lines.
Option 1 passes the low voltage detector for 0,5 seconds when starting the
hoisting motor and in new versions (> P2.13) also while the hoisting motor is
running.
Note: The torque of the hoisting motor depends on the supply voltage - if
the voltage drop is too big when starting the hoisting motor, it is
possible that the hoist is not able to lift the nominal load due to low
voltage and the hook may go down despite of up request!
Option 2; Changing of direction
Option 2; Changing of directionOption 2; Changing of direction
Option 2; Changing of direction (> P2.12) [Password 2-764]
Option 2 changes the operation of CU1's internal check routine. Normally this
property is always activated as factory default since > P2.13.
Option 3; DynAHoist option; Ready-output
Option 3; DynAHoist option; Ready-outputOption 3; DynAHoist option; Ready-output
Option 3; DynAHoist option; Ready-output (> P2.12) [Password 2-393]
This option is allowed to use with DynAHoist only.
By using this option, it is possible to connect the CU1's Ready-output to the
DynAHoist's fault circuit (i.e. if the CU1 detects a safety risk the DynAHoist will
be stopped immediately.)
Note: If Option-3 is selected, the Ready-output CU1:7-CU1:8 does not
operate similarly as the Ready-light on CU1's front panel (and thus
the Remote indicator can not be connected to the Ready-output).
Option 3 changes the operation of the Ready-output so that the Ready-
output is OFF in case of alarm due to Temp
1)
, Load
2)
or Brake
2)
.
1)
Ready-output is OFF as long as the Temp-alarm is on - this prevents
also lowering with DynAHoist.
2)
Ready-output is OFF for 0,5 seconds when trying to drive upwards
as long as the Load- or Brake-alarm is on. Lowering is possible.
