by the Owner
c. Burnet control system to be furnished under these'specifications
The power control diagram is a graphic, representation of the connect'.-Nn and
source of equipment' supplies. This diagram is not suitable for detai_ed
wiring information but is included to show the alternate sourwt of power
to each piece of equiprient.
21.5.2 Owner-furnished Equipment. The following equipment will be fur-
nished by the Owner. The contractor shall ppsa ticipate in the functional
coordination of Owner and Contractor-furnished equipments and design his
equipment so that interconnection is facilitated.
Dual Safet Interlock stem. Two completely independent safety interlock
systems will be used to obtain a main fuel trip.
A fuel trip is achieved on coincident requirement of the two systems by
use of two 3-way solenoid valves. Each interlock system actuates one
valve and the valve ports are interconnected so that coincident operation
of the two solenoid valves results in closing the fuel safety shutoff valve.
The systems are a-c de-energized to trip relay types. The relays will be
mounted in the Owner's relay panel.
Purge and Interlock Panel. An insert panel will be located on the combus-
tion control panel. The panel will contain Master Specialties Serie:l 2100
lights to indicate the status of each trip function in both safety systems,
the Fnsition of ill fuel safety shutoff Aad vent valves and the status and
condition of the burner control system. Each function will. be indicated
by a two color light where red is the operative condition and green is the
inoperative condition. The panel will also contain toggle switches for
manual operation of the safety shutoff and vent valves.
