HONEYWELL MODEL 700/800 SIGNAL PROCESSOR AND VIEWING HEAD
9 66-2069EP—08
Connection of the Honeywell type C330S cable to the
viewing head plug is shown in Fig. 7. Cable preparation
should be done as follows:
1. Prepare C330S wire at plug end similarly to Fig. 5.
2. Assemble the field-wireable plug as shown in Fig. 7.
Ensure that:
a. Wires and LEDs are in proper locations per Fig. 4.
b. Braided shield is on outside of ferrule, and
pressed against housing when assembled.
c. Solder drain wire to housing at one of two holes
at entry (see Fig. 6).
d. Connector back plate gasket is in place before
installation.
e. After assembly, check that connector is tight and
well secured.

Protecting the Viewing Head Cable
(Connector Series)
Note that when the wiring needs to meet Class I, Division 2
requirements for use in hazardous locations and when
conduit is used, the conduit must be sealed where the
cable passes from the hazardous location to the non-
hazardous location in order to keep potentially hazardous
gases from being conducted into the non-hazardous area.
Viewing Head Connector LED
Indicators
The viewing head connector has orange and green LEDs
which can be viewed from the rear of the connector when
the connector cover is removed.
The green LED displays the pulses out of the viewing head
and the orange LED shows that the self-checking signal
from the signal processor is reaching the viewing head. If
power is on at the signal processor, the orange LED should
flash at one pulse per second, even if the viewing head is
not plugged in. This is helpful in troubleshooting.
NOTE: IMPORTANT INSULATE DRAIN WITH SHRINK TUBING LEAVING 3/8" STICKING OUT.
