GENERAL PURPOSE CHASSIS
Zoltech offers a variety of control panels for the VX-11 chassis:
A VX-11 control panel assembly consists of a number of parts, depending on the application. VX-11 front panels have two types of control panel openings: Either a rectangular hole, about 2"W x 4½"H or a group of four smaller square and rectangular holes. The larger hole provides clearance for a control panel mounting bracket. The bracket fastens to the bottom panel of the main chassis. The bracket then provides mounting for the other control panel parts. One of these parts is a nomenclature plate that goes on the front of the bracket to label the functions of the switches and indicators. The alternate opening, the group of four small holes, provides mechanical mounting for the power switch and clearance for the other switches and indicators. The same nomenclature plate that was used with the control panel mounting bracket goes on the front panel, over the four holes. In this case, the control panel PCB itself is fastened directly to the front panel rather than to the bottom panel via the bracket. The type of control panel opening used depends on whether the front panel must be removed for normal assembly or maintenance. If maintenance removal of the front panel is required, the control panel will be mounted on the bracket so that it will stay with the main chassis even when the front panel is removed. If the front panel is rarely removed from the chassis, then the alternate (four small holes) opening is used. The appropriate mounting hardware and nomenclature plate is included with each control panel.
The No-Function Blank (NFB) has no specific orientation. It is simply a blank cover panel for the control panel opening that is present in most VX-11 front panels. Since front panels without control panel openings are available, the NFB panel is rarely required.
The Power Switch Only (SPP-x) panels provide a rocker switch intended to control the AC power in a chassis. There are two power switch options available: the normal power switch has DPDT contacts rated at 6A @ 250V and is not illuminated. The -xA switch has contacts rated at 16A @ 250V (80A inrush) and includes a neon lamp current limited for 110VAC for illumination. When used with the AC PDA, the SPP-x switches control both sides of the AC input. The switch is marked with the universal I and O.
