Nexen PC210 913071 - Manual (Page 8)

FORM NO. L-20341-E-0208
Setup controls are located inside the cover on the
front panel of the PC210. These controls are used to
customize the control logic of the PC210 to the indi-
vidual machine (See Figure 5).
Web Splice Sensitivity Control indicated by "SENS"
regulates the sensitivity of the PC210 to splices.
Normally set to Position 3, it has no affect on double
feed signals when the machine is in a sheet-fed
mode or on web break sensitivity.
Gain Control adjust the level of the signal from the
Sensor
Mode Selector Switch indicated by "MODE" programs
the logic of PC210 to correspond to the machine-
feed conditions. The various positions are described
below.
(Mode 0) Not Used
(Modes 1 and 4) Web Splice Only
Used when the only indication wanted is a double
thickness splice on a web feed machine. The
difference between Modes 1 and 4 is the speed of
the machine.
(Modes 2 and 5) Web Splice and Web Break
Used when indication of double thickness (a splice)
and absence of web (web break) are needed on a
web feed machine. The difference between Modes
2 and 5 is the speed of the machine.
(Mode 3) Used to calibrate the Sensor signal for
web splice/double sheet feed when the PC210 is to
be used in Modes 1, 2, or 7.
(Mode 6) Used to calibrate the Sensor signal level
for web splice/double sheet-feed when the PC210 is
to be used in Modes 4 or 5.
(Mode 7) Used when the PC210 is used to detect
double sheet feeding in a sheet-fed machine.
Web Thickness Selector Switch sets the standard
product thickness to be run. It has two ranges:
(LEFT) 0.002- 0.008 in. [0.05-0.20 mm] and
(RIGHT) 0.008-0.031 in. [0.20-0.80 mm].
Output Reset Selector Switch determines method of
reset after a double sheet-feed or web splice has
been indicated. The auto reset relay (switch to the
left) automatically resets the PC210 to normal state
after a splice or double sheet enters the Sensor.
The time delay is adjustable from 0.2-6 seconds
(standard factory setting is 2 seconds). The manual
reset relay (switch to the right) must be reset to
normal state with the Reset Switch on the front panel
or by a momentary contact between Terminals 15
and 16.
Sensor Select Switch The Sensor Select Switch
determines which sensor is to be used. UH200 with
the switch in the left position, and UH215 with the
switch in the right position.

NOTE: For machine speed below 30 ft. per minute [10 meters per minute] use Modes 4, 5, and 6.
