General Description

1
The Montalvo Z4 Unwind tension controller provides precise automatic control of web tension.
The progressive PID regulator automatically compensates for roll diameter. The controller is used
in a closed loop, of which the load cell roller and a brake (or other tension-affecting device) are part.
To properly set up and operate the controller and to take advantage of all its available features, it
is important to have a general understanding of the controller and its place in the tensioning
system (please refer to the diagram on the following page). A typical pneumatic system is
displayed; however, the same principles apply to any other closed-loop control system. The
controller outputs of 4 to 20mA and 0 to 10V enable the controller to interface with a variety of
output devices to control web tensioning brakes, clutches, or motors.
Load Cell Function
The Z4 is typically used with a pair of half bridge load cells (transducers). It can also be used
with single half or full bridge type. The signals from the paired load cells are summed together
to indicate total web tension across the entire web. Each load cell contains two strain gauges
connected in a series. The two load cells are connected so that the four strain gauges form a
Wheatstone bridge conguration supplied with ±2.5V. The web tension transfers a force to the
load cell roll, changing the resistance values in the bridge. The resulting voltage change is
amplied and calibrated to display actual web tension.
Converter Function (Brake)
The Z4 can regulate either pneumatic or electric brakes. An I/P converter, used with pneumatic
brakes, converts the 4 to 20mA regulator output to a proportional 0 to 75 PSI (0 to 6 bar)
output. Electric brakes require a voltage converter. Other converters may be used, depending
on the application. Contact Montalvo for further details.
Brake Function
One or more brakes may be controlled, converting the pneumatic output pressure from the I/P
into torque. This torque in turn determines the web tension.
Diameter Signal
To optimize the tension system, a diameter signal is recommended. Diameter can be calculated
by signals from two proximity switches or it can be connected from an analog device such as an
ultrasonic sensor or other device.
Auto Mode Function (Closed Loop)
The operator sets the desired tension using auto setpoint control. The controller compares
actual tension to the auto setpoint, and adjusts output until the actual tension and setpoint are
equal. Because the web itself is part of the feedback loop, the Z4 can quickly compensate for
speed and diameter changes, and for other factors that affect tension during the process.
Manual Mode Function (Open Loop)
The operator sets the desired brake pressure using manual control. The web tension is still
measured and displayed on the tension meter, but is not regulated in this mode. To maintain
tension, the operator must make continued output adjustments.

Item Description
Manual Setpoint
Sets controller output at a constant level when the controller is in
manual mode. (Manual setpoint on a 0 to 100% scale produces
0 to 100% output). Once scaled, the output can be PSI, volts or mA.
Auto Setpoint In auto mode, output is automatically regulated so that actual
tension reaches the Auto tension setpoint.
Actual Tension Displays actual tension on a scale of 0 to 100% or user assignable
tension range.
Controller Output Meter Displays controller/regulator output on a scale of 0 to 100% or
user assignable output range.
Manual / Auto Toggles between manual and auto mode.
Tension On/Off Button Turns tension on and off. Output is zero when off.
Yellow Power LED Indicates that power is on.

3.1 Warning, EMC, and Safety
Warning: Electrical installation must be done by skilled personnel. Wiring must meet all
applicable codes and standards.
Refer to the appropriate wiring and terminal descriptions for external connections.
The maximum external fuse on the input is 10A.
Note: 0V and PE are internally connected.
Note: Double-check the accuracy of all wiring connections before applying power to the
controller. Damage caused by improper wiring is not covered under warranty.
EMC Requirements: Connect the protective ground wire to the terminal marked PE. Ground
wires should be as short as possible. Connect the controller PE terminal and enclosure to a
common ground.
Use only shielded cables for all external connections. For analog signals, terminate the shield at
the controller end; for digital signals, terminate the shield at both ends.
Keep signal cables away from supply cables or any wires that conduct high current. For the
best noise immunity, run signal cables close to the machine frame, mounting plates, or other
grounded structures.
SAFETY INFORMATION
The following safety symbols appear in this manual.
Caution
Failure to follow installation and
setup instructions in this
manual may result in equipment
damage or personal injury.
Electrical Hazard

1. Check that load cells are mounted and oriented properly, referring to installation instructions.
2. Before applying power to the controller, check that analog tension meter, if used, is set to
zero. If using Montalvo M4 tension meter, mechanically adjust needle with screw at base of
meter scale as needed. Note: If using Z4 HMI, digital display of tension will match circuit
board adjustment.
3. Apply power to the controller and let it warm up for at
least 10 minutes.
4. Enter [Status Menu] and scroll to [Tension] .
5. With web removed and no tension applied to the sensing
roller, adjust potentiometer R1 until tension readout on
circuit board is 0%. If value is below zero, turn R1 clockwise; if
above, turn counter clockwise. Note: R1 and R2 are 25
turn potentiometers, so many rotations may be required.
6. Thread a rope over the center of the tension-sensing roller
following the exact path of the web. Make sure that the rope
extends at least one roller before and one roller after the
sensing roller. Make sure that the rope does not pass over
any dead bars or non-freewheeling rollers. Fasten one end
of the rope securely.
8. Attach a weight of known value to the other end of the
rope. For best results, the weight should be at least 25%
of the analog meter’s full-scale value. A tension value below
0% with the weight hung indicates that the signal from the
load cells is reversed. In the event of such a reversal, switch
wires 12 & 14 and 41 & 43 on the terminal block. To
break friction between the rollers and the rope, rotate rollers
in the direction of the weight.
7. Adjust potentiometer R2 until tension readout on circuit board
is identical to the hanging weight. Scaling on an analog meter
or Z4 HMI is automatic. Tension will appear as a percentage
value (%).
9. Remove weight and check that tension meter returns to
zero. If not, repeat steps 4 to 7.
10. If a second calibration range is used, repeat steps 4 to 8,
using potentiometer R3 for calibration of the second range.
See 3.10 Digital Input (24V).

Section Description
DI 1 31 Manual Red
When activated by a 24V signal, the controller
switches to manual mode. Manual setpoint
then sets the output level. When deactivated,
the controller regulates from the manual level.

Splice
This input is used to control the regulator during
the splice sequence.
DI 3 32 Tension

5.4
Roll
Change
When activated by a 24V signal, the output
goes to zero and the regulator is reset. This
function is used at roll change. When the input
goes low, the regulator is set to the new roll
parameters.
DI 4 3 Cal-2 Yellow
When activated by a 24V signal, the controller
will change to a second calibration range for
the load cell input. This is typically used if a
double tension scale is necessary or if the web
runs two ways with different wrap angles.
DI 5 34 Run Red
5.5
Start
and
5.7
Hold
The Run signal from the machine has to be
connected to this input. This is used to control
the starting sequence, and to release the
regulator when the machine is running. When
the signal is deactivated and the machine is at
zero speed, the regulator is held at a constant
stored level.

Run - Digital Input 5 (terminal 34)
The run input serves the following purposes:
1.To control and release the regulator at start-up.
2.To stop and hold the regulator when the machine is not running.
For set-up, see 5.5 Start Menu and 5.7 Hold Menu.
Electrical Wiring
Below a typical example of how to connect the run signal:
Parameter Descriptions
[DI-5 Invert] Select: [NO] or [YES]
The run signal is activated with a high (24V) signal. If the inverted function is needed, then
change the parameter [DI-5 Invert] to [YES]. Default is set to [NO].
