    The second function is the tension regulator. It compares the output signal from the transducers with the signal from the AUTO Set potentiometer on the front of the SteadyWeb enclosure. If there is a difference, the regulator will either increase or decrease tension to equalize them. The tension amplifier and the tension regulator are both located on the Control board.

  • Page 28: Standard Features

    Almost all machines that process a continuous web have more than one tension zone. The SteadyWeb controller can be used in any tension zone, however it may need to be configured for the zone it will be used in. The information below will be used later to determine the correct configuration.

  • Page 31: Power Voltage Selection

    5.3 POWER VOLTAGE SELECTION (See Figure 17, page 22) The SteadyWeb controller is designed to operate on either 115v-60Hz or 230v-50/60Hz power. Select the correct voltage for your application with the Power Selector Switch, SW203. The left position selects 230v; the right position selects 115v.

    Measure voltage between test points TP117(+) and TP107. Adjust the -LIMIT pot. for 10 volts. d) Set the SW103 switches as required for the control voltage desired. For all SteadyWeb controllers having pneumatic (12P) or high voltage outputs (12V) set the switches as shown for the 0 to +10 volt output.

  • Page 33: Emergency Stop

    5.6 EMERGENCY STOP (See Page 4 for description, Figure 17 for switches) An external contact is required. The controller will be in the Emergency Stop mode as long as the contact is closed and will go to the AUTO mode as soon as it opens. No adjustments are required. Works in the MANUAL control mode, too.

  • Page 34: High Voltage Output Module (12V Only)

    5.7 HIGH VOLTAGE OUTPUT MODULE (SteadyWeb Version 12V only, description on Page 1) This module, called the V-OUT card, contains the SCR bridge and driver circuitry to produce the output voltage of the controller. It is designed to operate with either 115v or 230v input power and to produce 90vdc, 45vdc, 24vdc, or 180vdc outputs.

    b) Turn power on. Turn Tension on. Switch to MANUAL control mode. Turn the MANUAL pot. all the way counter-clockwise. Connect a voltmeter to the output terminals on the VOUT card. c) Turn both SPAN and OFFSET pots. fully clockwise. Observe the voltmeter and turn the OFFSET pot.(RT402) slowly counter-clockwise until the voltmeter reads 0.

    Control board fully clockwise to enable full output. Adjust the M-SENS pot. so the output meter reads 100%. 5.12 PNEUMATIC OUTPUT MODULE (SteadyWeb Version 12P only) (See Figure 16 for adjustment, see Page 1 for description) The air pressure regulator is preset to 80psi (5,5 bar). No further adjustment is needed. Set the PNEU FS pot.(RT201) for 75 psi maximum output.

  • Page 37: Ratio Up/Down

    5.13 RATIO UP/DOWN (See Page 4 for description, Figure 16 for adjustments) NOTE: The Ratio function is not normally needed for most applications. Use it only if there is a large tension fluctuation during or directly after the splice. The output of the controller is locked (see Section 5.17 Sample and Hold following) and then multiplied or divided when an external contact is closed.

  • Page 38: Remote Tension On/Off

    5.14 REMOTE TENSION AMPLIFIER INSTALLED? (See Page 7 for description, Figure 16 for switches) The SW102 switches must be set for the presence or absence of the Remote Tension Amplifier option. Set the switches as shown to accept the tension signal from the amplifier inside the controller (local) or the remote amplifier.

  • Page 39: Soft Start

    5.17 SAMPLE AND HOLD (See Page 5 for description, Figure 16 for switches) The output of the controller is measured and then locked at the measured value upon the closure of an external contact. The output remains locked only as long as the contact is closed. The status light on the front panel will light when the output is locked.
  • Page 40 c) Set the SS TEN DLY pot. (RT115) for a short time delay before Soft Start actuates. This eliminates nuisance actuation if tension drops for only a short time. The range is about 0 to 3 seconds. Turn the pot. CW to increase the delay. There is no delay when leaving the Soft Start mode.
