Connections and Display Selection Switch
A. Current loop to remote display
B. Display selection switch in down position for remote selection
If the display is in a remote location, the display is connected via a current loop with the hoist-monitoring
unit. The current loop is between terminals 32 (CL-A) and 33 (CL-B). Because a current loop is not
sensitive for electrical disturbances, it is not needed to use shielded cables for the display connection.
With the red display selection switch on top of the hoist-monitoring unit it is possible to switch between
the display locations. The display selection switch must be in the down position to select the remote
location active.
Remote display and display in the unit cannot work simultaneously.
