HON 670 / HON 671 Controllers Component Documentation
The configuration levels of the controllers HON 670 / HON 671 can be varied in some respects
using individual components.
The following individual components are always part of the device:
▪ Spring adjuster of the pilot spring
▪ Amplifying valve
▪ Comparator stage
▪ Base plate
▪ Pressure unit
The following individual components are installed in some versions of the device:
▪ Comparator stage
▪ Diaphragm measuring unit
▪ Diaphragm assembly with ball guide sleeve
▪ Metal bellows measuring unit
The comparator stage as an individual component is executed in three models with different
designs in dependence on the control range (W

The designs that use the imperial system of measurement feature ports that conform to
Anglo-American thread standards and use inches as a unit.
The designs that use the metric system of measurement feature ports that conform to Euro-
pean thread standards and use metric units.
The technical specifications and the spare parts lists and spare parts drawings in the appendix
describe all the models of the HON 670 / HON 671 controllers.
The Maintenance section describes the controller using the example of the models with a
diaphragm measuring unit and a metal bellows measuring unit. It does not explicitly describe
every single version and design.
If you have trouble understanding the information in this documentation, contact the manu-
facturer without fail before starting any work on the device.
