1. SENSORS (Terminals 1 through 8)
All sensors are wired to Terminals 1through 8 (See
Figure 1). For CPC both PH16s or both AW150s
must be installed. MW 1000 is used when sensing
web edge position with a pneumatic sensor.
2. AUTO CENTERING SENSOR, Optional (Terminals
9, 10, 11, and 38)
The Auto Centering Sensor is used to realign the
guide roll mechanism or roll stand being controlled
to its mechanical center position. This sensor is not
required in all installations. If auto centering is used,
mount the sensor according to instructions provided
with the sensor and make electrical connections as
shown (See Figure 1).
3. CONTROL OUTPUT, Optional
(Terminals 14 and 16)
A ± 12 VDC, mA corrective signal is available at
Terminals 14 and 16. This signal is not isolated. It
must be interfaced through isolated input Terminals.
This Control Output is unaffected by the Output
Selector Jumper (See CONFIGURATION, Output
Select Jumper).
4. SELECTOR CONTROL, LA 20, Optional
If the Selector Control LA 20 is used, connect it to
Terminals 12, 17, 18, 19, 20, 21, 22, 26, and 39, as
shown in Figure 1, using cable provided with the
unit. This cable may be extended up to 50 Ft. [15m]
using 18 AWG [0.9 mm] cable.
5. POSITION TRANSMITTER, Optional (Terminals
23, 24, 25, and 38)
In most cases, the web guide system is operated in
integral mode and does not require a Position
Transmitter. Integral mode is more accurate than
proportional mode and is therefore preferred.
In rare cases, where good control is impossible due
to slip between the web and the steering rolls, bad
sensor positioning, low tension, or very low web
speeds, it may be necessary to add a Position
Transmitter and operate in proportional mode.
A 2K ohm Pot may be used as a Position
Transmitter.
CAUTION
Make sure P/I Selector Switch is set to
P (See CONFIGURATION, P/I Filter
Switch).
6. REMOTE FINE ADJUSTER, Optional (Terminals 27,
28, 29, and 38)
A customer supplied Remote Fine Adjustment
potentiometer, rated at 2K ohms, may be installed
(See Figure 1). Install the Remote Fine Adjuster
close to the web path to allow the operator a fine
adjustment capability without having to physically
reposition the sensor.
7. LINEAR ACTUATOR (Terminals 30 through 34
and 39)
Linear Actuator electrical connections are the same
whether the actuator is a separate unit used for
moving a roll actuator or a component of a guide roll
mechanism.
CAUTION
Observe wiring polarity at Terminals 30
and 31. When used with an actuator
without Limit Switch Leads, short Ter-
minals 32, 33, and 34.
8. ALARM CIRCUIT, Optional (Terminals 35, 36,
and 37)
An over travel alarm circuit is provided. When the
actuator has reached its full travel in either direction,
the Alarm Circuit is actuated. This over travel signal
can be picked up as a normally open signal at
Terminals 35 and 36. This signal can also be picked
up as a normally closed contact at Terminals 35 and
37. The contact ratings are: 0.5 A @ 250 VAC, 1 A
@ 24 VDC.
9. AC POWER (Terminals L, N, and G)
Choose from 100, 110, 120, 200, 220, or 240 VAC.
