This one has the last pages - missing in the post of the otherwise complete manual posted by Jakob E. Especially the parts list for switch unit A3 and all pages regarding switch unit A4.
Plus a couple of Hi-Res scans of some of the schematics.
The complete manual for the 179-140 is in one of the earlier posts.
Here is an alternative page 3: Terminals and interconnections.
Only valid for the serial numbers mentioned in the document.
Different pin-out on the 23-pole Tuchel. The normal page is just for reference
NTP 182-120 full manual.
In the schematic section it runs on +24V (same as in the earlier post from Jakob), but the technical specification and the pinout are for +/- 15V.
