Equipment Preparation - Honeywell TotalPlant LCN System Installation

3.3 EQUIPMENT PREPARATION

The following safety procedures must be followed:
1. The power switch or breaker(s) on the system power control panel must be in the
OFF position.
2. All cabinet and console power entry (PE box) circuit breakers must be in the OFF
position.
3. If an optional cabinet is installed, its circuit breaker must be in the OFF position.
• Set the LCN equipment cabinets in place according to the site configuration-layout plan.
Do not exceed LCN cable-length limits, see LCN/LCNE Cabling, subsection 3.6. Side
skins are not removable; however, the front and rear doors can be removed. Cabinets
can be placed side-to-side, as if complexed.
• Set the Universal Station in place according to the site configuration-layout plan. Do not
exceed LCN cable-length limits, see LCN/LCNE Cabling, subsection 3.6. Universal
Station console bays can be complexed; see Appendix A.
• Set the Universal Work Station (UWS) adjacent to a desk that holds the peripheral
CRT, keyboard, mouse and optional printer. The UWS electronics package and each
of its peripherals are equipped with 6-foot ac power cords. Provide two duplex outlets
nearby for their connection. Do not exceed LCN cable length limits; see Appendix A.
• Set the Deskside Global User Station components on a tabletop or desktop. The
electronics tower can be placed on the floor under the table or desk, directly under the
Monitor and keyboard.
Note that if the Universal Station (US) is located near an outside window, use shades or
drapes to ensure that direct sunlight does not fall on the US CRT touchscreen components.
Direct sunlight can cause the touch screen (photocells) to activate and the beeper to sound
off. Be especially aware of early morning and late evening low sun positions relative to the
CRT touch screen position.
• For Data Hiway coaxial cable-length limits and polled device-addressing constraints
refer to Section 4 of the Data Hiway Subsystem Site Planning manual or to the
System Site Planning manual.
• Open the front and rear door of the cabinet/console to gain access to the power-entry
box and the cable-entry cutout area.
• The Operator Interface Station power connection is located under the footrest cover.
- Remove the inside covers from each OIS leg.
- Loosen the three bolts along the top rear edge.
- Slide the footrest cover forward.
