The meter has a manual hauling function. With the help of the safety switch you can override the
main board control of the cable drum motor and make the sensor go up or down with the manual
hauling switch ( refer to
Description of the single components on page 10). Forcing the sensor to
go up might be necessary for example if the meter stops functioning correctly during an active

• Press the safety switch coming out of the front side of the connection terminal box to supply
the device with power.
• To make the sensor go up or down use the manual hauling switch on the top of the connection
terminal box (the switch has three positions: up/neutral/down).
