Operating and display elements
The switch at the motor protection serves as operating switch for the hydraulic
power unit and protects the electric motor against excessive current consumption.

"OFF" position = "0" = hydraulic motor pump off
 "ON" position = "1" = hydraulic motor pump on
The electro hydraulic pump will only start if the current supply has been released
at the control box by means of the "Start" pushbutton!
The optical filling level indicator fulfills the following functions:

"MIN" and "MAX" display for oil level and
 Visual control of the oil state
The temperature display integrated in the filling level indicator serves to visually
check the oil temperature.
The display range of the operating temperature goes from +20 ºC to max. +80 ºC.
The clogging indicator provides information on the degree of contamination of the
filter cartridge of the return flow filter.
The display instrument shows the following color ranges:
 Green = OK

Yellow = Exchange filter
 Red = Exchange oil and filter

set-ups
With the P/T distributor with depressurized circulation, unloaded start-up for the
pump is possible.
This start-up is easily possible by operation of the switching lever.

Vertical position = closed (operating position)
 Horizontal position = circulation operation
