Page 3: Introduction
1. Introduction The GRANITE™CHASSIS is a strong metal enclosure that delivers optimized thermal management and mounting convenience for a collection of GRANITE-series data acquisition (DAQ) modules. As a system that includes a rechargeable backup battery, it can be portable or stationary. Power can be supplied by AC or DC sources such as solar or rackmounted wall-power. -
Page 4: Precautions
To avoid ground loops, only allow a single path to ground. The second grounding lug is intended to connect subsequent devices that need to be grounded, such as one or more daisy-chained CHASSIS or GRANITE modules that are mounted external to the CHASSIS. -
Page 5: Initial Inspection
3. Initial inspection 3.1 Inspect packaging Upon receiving the GRANITE CHASSIS, inspect the packaging and contents for damage. Claims for shipping damage must be filed with the shipping company. Locate the order packing slip and compare the items listed on the packing slip to the items that were shipped. -

3.2 GRANITE CHASSIS parts Each CHASSIS is shipped with a box of tools and parts used to install GRANITE DAQ and measurement modules (purchased separately). The following table shows the common parts and tools used in CHASSIS setup. Some of the items should be saved for future use. -
Page 7: Quickstart
Turn power off while installing hardware and making electrical connections. Set the CH400 Power Switch to Off before starting installation. 1. Use a #2 Phillips Screwdriver to loosen screws for module mounting. NOTE: Mounting screws only need to be loosened two to three turns. GRANITE CHASSIS 5... - Page 8 2. Mount the CH400, if used, in left-most position, otherwise mount GRANITE DAQ here. Mount other measurement modules. See Mounting and installation (p. 11) for more details. FIGURE 4-1. Typical CHASSIS setup 3. Using the Flat-Bladed Screwdriver press firmly in the small slot of the Green 4-Pin Terminal Connector to open the wire slot.

Page 13: Mounting And Installation
To deliver optimal thermal performance where maximum heat dissipation is needed, mount the CH400 (when used) in the position furthest to the left as shown in the following image. For wiring convenience, mount the DAQ (GRANITE 6, GRANITE 9, GRANITE 10) next to the CH400. Mount measurement modules in remaining locations. When observing these mounting recommendations, the battery temperature is reduced, improving performance. -

7.2 GRANITE modules GRANITE modules mount in the CHASSIS using pre-installed anti-vibration screws; they simply need to be tightened when GRANITE modules are installed. If a screw is damaged, or the anti- vibration patch wears off, it may be replaced. -
Page 15: Tie-Downs
Leave slack in fixed cables, such as sensor cables, to allow for cable movement. Use a cable management arm (purchased separately) to keep cable bundles organized and movable. 7.5 Tie-downs Four ear loops on the CHASSIS provide anchor points to secure the CHASSIS. FIGURE 7-2. Ear loop locations GRANITE CHASSIS 13... -

8.3 Routing user-installed cables 8.1 Grounding CHASSIS It is not necessary to use ground lugs on the rear of the GRANITE modules as long as the GRANITE modules are clamped down tightly to the CHASSIS frame. In most cases, use a single ground path to avoid ground loops. - Page 17 The Temp cord, with stereo plug, reads a temperature sensor mounted next to the internal CHASSIS battery. This cord plugs into the BATT A Temperature or BATT B Temperature port on the CH400. When the CH400 is not used, tie this cable out of the way. GRANITE CHASSIS 15...

Solid aluminum top and rear panels are removable. Take out the four Phillips screws in each top panel to remove them. For the rear panel, loosen the Phillips screws to slide it up and off the keyhole mounting slots. GRANITE CHASSIS 16... - Page 19 FIGURE 9-1. Top panels FIGURE 9-2. Rear panel The removable panels can be customized by Campbell Scientific or others. For example, add cutouts for quick-attach connectors.

4. Set the CH400 Power Switch to On. 11. Maintenance Keep the GRANITE CHASSIS clean and dry. The GRANITE CHASSIS can be expected to deliver many years of reliable service. Eventual maintenance includes battery and cooling fan replacements. See Battery maintenance (p. -
Page 21: Battery Maintenance
Before replacing the CHASSIS battery, collect all data from the DAQ. Battery replacement procedure: 1. Unplug Detachable Power Cord (if present). 2. Unplug Green 4-Pin Terminal Connector. 3. Pull knob up. 4. Partially slide drawer out. FIGURE 11-1. Battery drawer GRANITE CHASSIS 19... - Page 22 9. Slide the drawer in, connecting the battery plug when about half way, then slide it the rest of the way in. 10. Ensure the knob seats again completely. 11. Plug the Green 4-Pin Terminal Connector back in. 12. Plug in the Detachable Power Cord (if present). GRANITE CHASSIS 20...
