INSTALLATION
3.3.4.3 SHU #1 / #2 Interface Connector (J6 & J7). These wires are to be connected directly to
the MicroCEM sample handling enclosure (SHU) and will control the operation of the
sample pump, drain pump, purge valve and calibration valve respetively. All toggle
switches in sample handling enclosure should be set to “remote” mode upon hookup of wire
so the MicroCEM analysis enclosure will control the full system.
The Digital Interface connector has a shell size of 14, 15 contacts. Each pin will accept a wire
size of 20 AWG. Connector and 6’ pigtail by Rosemount.
