HONEYWELL MODEL 700/800 SIGNAL PROCESSOR AND VIEWING HEAD
66-2069—02 6
Viewing Head Connector and Wiring
Viewing heads are wired to the appropriate terminals located
on bottom of the 700ACSP, 700DCSP, P531 or P532 signal
processors. The terminals are listed functionally in Table 2.
Connectors and cables are shown in Fig. 3, Fig. 4, and Fig. 5.
Fig. 3 shows the viewing head cable with the 1/2 in. NPT pipe
fitting and pigtail for use in a conduit. The PF model comes
with 50 feet of Honeywell C330S cable. This cable is
recommended for all new installations. It has ITC and CIC
ratings for hazardous location. Figs. 4 and 5 describe the
C330S cable used with the right angle field-wireable
connector. Refer to “Accessories” on page 9 for part numbers.
The customer may also supply his own cable; a replacement
mating viewing head connector should be ordered. Refer to
“Accessories” on page 9 for part numbers. The use of 22g, 4-
conductor cable with shield and drain is recommended. The
shield should be foil and braid type surrounding all
conductors. The shield should be connected to GND at the
processor end. The cable diameter should not exceed 0.307"
in order for it to go through the hex bushing in the connector.
But note that wiring the cable to the connector is not easy
because of the limited space. Also, the LED indicator
assembly must be mounted inside the connector and,
preferably, soldered in place. Thus, it is recommended to
purchase a pre-wired cable and connector assembly from
Honeywell.
NOTE: FOR CLASS I, DIV 2 RATING, CABLING IN
HAZARDOUS LOCATIONS MUST COMPLY WITH
NEC ARTICLE 500 REQUIREMENTS AND
APPLICABLE GOVERNING CODES.
In the U.S., cables should have UL’s ITC rating; in Canada,
cables should have CSA’s CIC rating. The recommended
C330S cable has both ratings.
NOTE: To obtain a NEMA 4X seal between the connector
and the viewing head, tighten the metal
connector ring securely.
