make or break any connection you have made. If you have configured your controller to turn Tension Off
when TLS occurs, Tension will also turn off.
If you have chosen
Alarm" key. Note that if a TLS alarm is active and you turn that mode off, you must press the Exit/Alarm
reset to turn the alarm off. It will not automatically reset.
In the setup menu, an item called TLS Relay Invert controls the TLS relay polarity during a TLS alarm. If
TLS Relay Invert is set to "Off" (default), the normally open contact is closed and the normally closed
contact is opened during a TLS alarm. If it is set to "On", the opposite is true. This allows the TLS relay
to be used as a "Tension OK" relay, closing when tension is in the desired range. One way to do this, is to
set both TLS Lo and TLS Hi modes to Raw (Momentary or Latched, as desired) and set TLS Relay Invert
to "On". Once TLS Lo and TLS Hi setpoints are entered, the relay will close whenever tension is
between the Lo and Hi setpoints. This provides a simple, reliable indication that tension is within range
without external logic, and can be used to sequence another part of the machine.
7. FuncTimeoutTime
As you set your controller up, you need to navigate into and out of menus. Sometimes it is convenient to
have a display return to the default screen automatically. If you wish to use this feature, navigate to Setup
FuncTimeoutTime
Menus->
Now, even if you leave your controller in a function menu, it will automatically return to the default
screen for operation.
8. Setup for remote Manual and Auto set-point potentiometers and switch
It is possible to reassign the function of certain unused analog inputs if you want to use external Manual
and/or Auto setpoint inputs. The inputs which can be reassigned (if unused) are the Line Speed, Roll
Speed, Remote Tension Amplifier, or Diameter inputs.
It is also possible to reassign the function of certain unused digital inputs if you want to use an external
Auto/Manual switch input. The inputs which can be reassigned (if unused) are the Ratio and Soft Start
inputs.
NOTE: It is not necessary to use both Auto and Manual pots remote - you may use either or both as desired.
CAUTION: It is strongly recommended you use 2 separate pots for Auto and Manual remote setpoint inputs.
But, it is possible to use a common pot for both if your operation requires this setup.
Connect the external switch or potentiometer as shown in Fig. 34. TB101 is on the Terminal Board. For external
setpoint potentiometers connect either side of the potentiometers to TB101 pin 22 (+10V) and TB101 pin 9 or
pin 11 (Gnd), and connect the wiper to one of the unused analog inputs (TB101 pin 7, 8, 10, or 12). The Pot
value should be 10K ohms.
