STARTING the ZM200
The device is ready to start after the speed has been selected and the housing cover closed. The rotor starts
after the green START button has been pressed and the performance screen appears on the display.
The current speed of the rotor is displayed in the top left. The performance screen
shows the performance range the machine is operating in. During grinding, the
100% range on the right should be avoided because the device is overloaded in
this performance range and reproducibility of grinding is no longer possible!
OPENING MECHANISM
MENU SETTINGS OPENING MECHANISM
This allows you to pre-select whether the grinding chamber cover should be raised automatically after
grinding has ended or may only be opened after pressing the button. If the function is switched off, the
pictogram appears on the display for confirmation.
When a distributor is used, two pictograms appear on the display: one is for the
distributor and the other to show that the opening mechanism function is switched off. The latter is prevent
the grinding chamber cover impacting against the duct during automatic opening. Please move the
distributor to the side before actuating the OPEN key!
AUTOMATIC STOP
MENU SETTINGS AUTOMATIC STOP
If a distributor is deployed, the run-on time for the ZM200 can be set here. This is the time after which the
device is stopped automatically when grinding has ended and the distributor emptied.
If this function is set, the appropriate pictogram appears on the display.
The function does not work properly unless the machine loading is constant, and not too low, because the
indicator for automatic stop is the loading. Should the device switch off prematurely due to too low loading,
it is advisable to work without the function.
ALARM
MENU SETTINGS ALARM
The error messages generated by false operation can be acoustically supported by an alarm.
If the function is switched off, the appropriate pictogram appears
SERVICE
MENU SETTINGS SERVICE
The service menu is sub-divided into four sub-menus:
TOTAL OPERATION HOURS
This counts the number of grinding hours, thus the sum of the times between START and STOP. The
times cannot be manipulated.
SOFTWARE VERSION
The version of the operating software can be called up and updated as required. If necessary, get in
touch with your Retsch distributor.
Should you have reached this menu by mistake and cannot return to the previous menu, switch the
device off at the main switch and re-start it.
CONTRAST/BRIGHTNESS
MENU DISPLAY CONTRAST
BRIGHTNESS
The contrast and brightness can be adapted to the particular user or ambient conditions (sunlight, glare
etc.).
If the contrast or brightness has been incorrectly set (the display can no longer be read), switch the device
off at the main switch, simultaneously hold down the START, STOP and COVER OPEN keys and switch it on
again. You will now see the language menu and the values for CONTRAST and BRIGHTNESS have returned
to the default settings.
