A web splice passing through the Sensor will cause the
Web Splice Indicator to glow and the Web Splice Relay
to change state. The Web Splice Relay and Indicator
will remain in this state until:
a. If output Reset Selector Switch is in the AUTO
position, the Web Splice Relay and Indicator Light
will return to their deenergized state after 2 seconds
(factory setting), or 0.2-6.0 seconds as set in
REMOTE RESET TIME SELECTION.
b. If the Output Reset Selector Switch is in the MANual
position, the Web Splice Relay and Indicator will
return to their deenergized state only upon pushing
the Reset Switch on the front panel or an Output
Reset momentary contact closure on Terminals 15
and 16.
Refer to Figure 9 for descriptions of the various splice
types and dimensions and observe the following rules
which apply to all splice detection.
The splice must be at least 0.8 In. [20 mm] long.
Web thickness can be from 0.0004-0.003 In. [1-00.8
mm].
Splice thickness must always be at least 0.002 In. [0.05
mm]. It may be necessary to splice as at A or C to
achieve this minimum value (See Figure 9).
If the splicing tape is less than half the thickness of the
web, it will be necessary to splice as at A or C (See
Figure 6).

1. Set the Mode Selector Switch to 1 or 4 as required.
2. Set the Web Thickness Selector Switch to
appropriate position, LEFT 0.002-0.008 in. [0.05-
0.20 mm] or RIGHT 0.008-0.03 In. [0.20-0.80 mm].
3. Set the Output Reset Selector Switch to AuTO or
MAN.
4. Set the Web Splice Sensitivity Control to 3.
5. Set the Power Switch to ON.
6. Check operation (See Table 4).
7. The Test Switch can be pressed prior to testing to
prevent the Web Splice Relay from changing state
during a test. The red LED imbedded in the Test
Switch glows while it is in test mode. Pressing the
Test Switch a second time extinguishes the LED and
allows the relay to operate normally.
8. The test described above can be performed at any
time but is normally required only when the web
thickness has changed.
