3500/93 SYSTEMDISPLAY
General Information
The 3500 System Display lets you collect data from all active channels in a 3500rack and display them on an LCD that can be mounted in a convenient location. A 3500 Monitoring System can have up to two 3500 System Displays.
The 3500 System Display consists of three major components: The Display Unit, the Display Interface Module, and the Display Interface I/O Module.
Display Unit
Two versions of the Display Unit can be ordered. The first version includes a reflective LCD module without a backlight. The second version of the Display Unit includes a transflective LCD module with a backlight. The Display Unit can be mounted over the front panel of a 3500 rack or mounted in a convenient location away from the rack. Section 3 shows how to mount the unit. The Display Unit is equipped with status LEDs and a membrane-switch keypad. Section 6 explains how to operate the Display Unit.
Display Interface Module and I/O Module
The Display Interface Module and the Display Interface I/O Module are full-height3500 modules that fit into a 3500 rack and support one Display Unit. The Display Interface Module and the I/O module can be installed in any slot except when a system face mount option is used. The Display Interface Module gathers and provides the machine parameter information and the configurations to the Display Unit upon request. It also provides the power to the non-backlit Display Unit that is installed within 100 feet of the Display Interface Module. Sections 5.2 and 5.3 show how to connect the Display Unit to a Display InterfaceI/O module.
Triple Modular Redundant (TMR) Description
The Display Interface Module is considered a "consumer" of data because it receives data from other modules, formats it, and sends it on to the Display Unit. Since the Display Interface Module does not produce data or provide data to other modules in the 3500 rack, a redundant Display Interface Module is not required. However, for applications that require redundant System Displays or require continuous display of more than 8 proportional values in bargraph format (or 16 proportional values in text format), two Display Interface Modules can be installed in the same rack to support two Display Units.
LED Description
The LEDs on the front panel of the Display Unit and the Display Interface Module indicate the operating status of the module as shown in the following figures. Refer to Section 8.2 for all of the available LED conditions.
Installing the Display Unit
The Display Unit can be mounted in one of four basic mounting configurations. The four mounting configurations are System Face Mount, Rack Mount, Panel Mount, and Independent Mount. The following sections describe how to mount the Display Unit for each of these mounting options in a typical installation.
Hardware Considerations
The slots in the rack are numbered from 0 to 15, counting from left to right. The power supplies go into slot 0, and the Rack Interface module goes into slot 1. Slots 2 through 15 are called "monitoring positions". The 3500/93 module can be installed into any of the monitoring positions, with the exception of the system face mount used for the Display Unit. In this case, the 3500/93 must be installed in slot 15. The 3500/93 System Face Mount option is not compatible with the3500/05 Mini-rack. Also, if the 3500/20 Rack Interface Module and Data ManagerI/O are to be used to interface to DDIX, TDIX, or TDXnet, refer to the manual on the 3500/20 for slot restrictions this may place on your configuration.
Installing a Bently Nevada External Power Supply
1) Install the conduit fittings to the independent mount housing (2 places). Route the power and Signal cables in separate conduits.
2) Install the brackets to the Display Unit using 10-32x0.37 Phillips pan head screws (2places).
3) Install the external power supply to the mounting plate.
4) Install the mounting plate to the housing using 10-32x0.37 screws.
5) Connect the power and signals using the Y-Adapter (reference section 5.3).
6) Place the Display Unit on the housing, and use the seal washers, the flat washers, and the 10-32x0.75 screws to clamp down the Display Unit to make a seal between the Display Unit and the Independent Mount Housing.
