SD200 TO SD220/SD230 MIGRATION
Replacement of installed SD200 units by SD220/SD230s requires the following wiring changes:
1. +24V and COM must be connected to both channels of the SD220/SD230.
2. SD200 faults for either channel are reported on both fault outputs. The fault signals on the two
channels of the SD220/SD230 are totally independent and must not be wired together.
3. If your installation uses the AUX input to quickly change between calibrations on different shell
materials, it is necessary with the SD220/SD230 to activate the AUX input on both channels
independently. The AUX inputs are not slaved together as in the SD200.
Configuration of the SD220/SD230 has been simplified as compared to the SD200. It is no longer
necessary to remove the cover to change options. These changes include:
1. The DIP switches, now eight per channel instead of four per unit, are accessible through a
window on the front panel.
