3.0 ADJUSTMENTS
3.4.1 TLD Low Limit Calibration - Put TLD select
switch to L position. In order for the TLD circuit to
operate, the TLD switch on the front cover must be on
(illuminated). If the switch is off the TLD function is
bypassed.
The tension limit detector level (2P) on the TLD card
should be adjusted slightly below the minimum operating
tension. The tension limit detector delay (1P) on the
TLD card should be adjusted for the minimum time
delay without causing the TLD relay to trip on normal
tension transients.
When the tension drops below the tension limit detector
level set point, a set of normally open and normally
closed relay contacts on the TLD card will switch
states.
3.4.2 TLD High Limit Calibration - Put TLD select
switch to H position. In order for the TLD circuit to
operate, the TLD switch on the front cover must be on
(illuminated). If the switch is off the TLD function is
bypassed.
The tension limit detector level (2P) on the TLD card
should be adjusted slightly above the maximum operating
tension. The tension limit detector delay (1P) on the
TLD card should be adjusted for the minimum time
delay without causing the TLD relay to trip on normal
tension transients.
When the tension rises above the tension limit detector
level set point, a set of normally open and normally
closed relay contacts on the TLD card will switch
states.
3.5 ISOLATION AMPLIFIER OPTION
Mount the isolation amplifier card to the indicator circuit
board with the four plastic standoffs as shown in Figure
2. Connect the short 3 wire cable from 2TB on the
isolation amplifier card to 3TB on the indicator circuit
board.
Position the switch on the isolation amplifier card to the
0-10V position for a 0 to 10 VDC isolated tension output
signal, or to the 4-20mA position for a 4-20mADC
isolated tension output signal.
3.6.1 Decimal Point Selection
3.6 DIGITAL TENSION METER
A signal conditioning circuit is included on the indicator
circuit board for displaying the tension on a digital meter.
The moveable jumper on the circuit board should be in
position 7J.
When the 0-10 VDC tension output signal is fed to 1TB-
10 on the circuit board a conditioned adjustable 0 to 2
VDC for the digital meter is present at 1TB-11.
Potentiometer 5P of the signal conditioning circuit
normally is factory adjusted for a 0-1 VDC output with
a 0-10 VDC tension output signal as an input. This
allows a 3½ digit 0-2 VDC digital meter to display 100.0
at full scale.
By adjusting 5P, the full scale reading on the 2 VDC
digital panel meter can be changed to any reading
between 35.0 to 199.9 with a 10 VDC tension output
signal present at 1TB-10.
