1. Red LED (Fault and Warning indication)
2. Orange LED (Tare load active)
3. Green LED (OK and Run indication)
The display unit shows in the large text field the actual or tared load. Also warning and fault messages
are shown in the display. Parameter values can be read and set via display unit after a correct password
has been given. Load information are displayed in a single row, other information are displayed in two
rows. If display is inside the hoist-monitoring unit, the red display selection switch must be on the local
position (up position).
Please note that the hoist-monitoring unit is designed for overload protection. The displayed load
has an accuracy of approx. ±5% of the rated load and is thus not suitable to be used as a calibrated
weighing scale.

3.2 LEDs
There are three LEDs inside the display unit. The left red LED is for fault or warning indication. The
orange or yellow LED in the centre is active when the tare load is selected. The right green LED is on
when the hoist-monitoring unit is OK and blinks when the hoist is running.
Action / LED Red LED (Left) Orange LED (Centre) Green LED (Right)
Illuminated continuously Fault Tare load value displayed OK, not running
Blinking Warning and Service - OK, running
Not illuminated OK Actual load value displayed Fault
OK state means that the hoist control unit is working normally and no fault or error has been detected.
When a driving output or the run feedback in inverter application is active, the green LED is blinking.
Warning means that a condition monitoring value exceeds the corresponding design value. Running the
hoist is possible, but safe using is not guaranteed.
