PAGE 32
MODCELL Multiloop Processor ELECTRICAL CONNECTIONS 3.4.2 Shield Ground The shield terminals, Figure 3-1, are only connected to one another; they are not internally connected to chassis ground or circuit common. Two brass jumper straps are included with each processor to connect chassis ground and/or circuit common to the shield terminals. Failure to make these connections renders all shield connections useless. When installing the jumpers consider the following: 3.4.
PAGE 33
MODCELL Multiloop Processor ELECTRICAL CONNECTIONS 3.4.5 Noise Prevention Measures Primary power circuit distribution system: • Ideally, each microprocessor-based device should be provided with an independent dedicated power source. Where this approach is not feasible due to space available or cost per device an acceptable alternative is to install constant voltage, isolation transformers in the branch circuit where the microprocessor-based device is installed.
PAGE 34
MODCELL Multiloop Processor ELECTRICAL CONNECTIONS 3.5 • Any connection made to provide a noise ground should be kept as short as possible using the largest practical wire gauge. This is necessary to keep the inductance of the connection as low as possible. Bear in mind that noise spikes have very short rise times and that any inductance will appear as a high impedance.

MODCELL Multiloop Processor APPENDIX B - SUMMARY OF HARDWARE DIFFERENCES At least one cold junction compensation input is recommended for each controller to sense the temperature at the terminal block. The CJIM module, Figure A-1, has been replaced by a 2009AZ__2__ 2-wire RTD Input Module with RTD sensor as described in Section 3.5.6 for cold junction compensation.

MODCELL Multiloop Processor APPENDIX B - SUMMARY OF HARDWARE DIFFERENCES B.6 MODEL A ICN COMMUNICATION MODULE The Model A ICN module has no 24V dc supply and is replaced by the Model B ICN module which does have a 24V dc supply. If only MODCELL instruments with Model A ICN modules are on the network, the instrument with the lowest ICN module address automatically terminates. This check is made each time the ICN is restarted.
