10.1 Removal

WARNING - General dangers!
Before removing or disassembling the device, check for hazardous process conditions such
as pressure on the device, high temperatures, aggressive or toxic media, and so on.
Read the instructions in the sections "Safety" and "Electrical connection", and perform the
steps outlined there in reverse order.

10.1.1 Removing the electronics

If the electronics housing needs to be unscrewed from the measuring equipment/measuring
cell, the electronics must first be removed from their housing to prevent them from being
damaged.
1. First, unscrew the housing cover.
NOTICE - Potential damage to parts
Please note that a locking screw is used.
2. Following this, remove the LCD display (if present) from the electronics. To do this, slacken
the two screws.
3. Slacken the two fixing screws for the electronics and carefully remove the electronics from
their housing.
4. Remove both plugs from the electronics. Both plugs feature mechanical polarity protection,
and the smaller of the two also has a mechanical locking device.
5. Grasp the two plugs from the front between your thumb and forefinger, and push them
together. This opens the locking device.
6. Pull the plug out of the socket. Place the electronics on a suitable surface.
7. Unscrew the electronics housing from the measuring equipment/measuring cell.
