d) Measure the input voltage to the digital meter at pin 1 (+) of socket J901 (S13), and test point
TP904 (-) (TP4).
e) Adjust the ZERO A pot. on the Control board for 10VDC at the points in d) above.
f) Adjust the CAL ADJ pot.(TR901) (TR1) to set the Digital Meter to the full-scale value selected.
g) Calibrate the meter according to the procedure in Section 4.
CAUTION:
When setting the ZERO
pot. pay attention to the under-range indicator. The correct setting is where the light just goes out
as the ZERO pot. is turned clockwise.
6.5 DUAL CALIBRATION
(Dual meter scales and dual stability adjustments, see Page 6 for description)
Refer to Section 4 for procedure to calibrate the tension meter. The ZERO B and CAL B pots. are
adjusted in the same way as the ZERO A and CAL A pots. See Section 7 for adjustment of the STAB
and RESP pots.
6.6 DUAL TRANSDUCER INPUT (See Section 1.5, Page 6 for description)
The Dual Transducer Input card plugs into the left option socket on the Power board. This card has
no adjustments or switches to set. The Dual Calibration option is required. Follow the setup procedure
in Sections 4 and 6.5 for each position of the transducer set selector switch. This switch is located to
the right of the tension meter on the front panel.
6.7 EXTENDED RANGE (See Page 6 for description)
See Section 5.22, page 34, to set the transducer voltage selection switch. No adjustments or special
electrical connections are needed.
6.8 PULSE TACHOMETER CARD (See Page 6 for description, Figure 16 for switches)
This card is only used in conjunction with the Taper option, speed-actuated Soft Start, or Speed
Follow. It is plugged into the RIGHT hand option socket on the Power board. The left socket is for
special cards, if used.
There are two +10 volt DC outputs on the card, named LTACH and RTACH. Both are needed for the
Taper option, but only LTACH is needed for the speed-actuated Soft Start function. LTACH refers to
the line (machine) speed pulse tach. RTACH refers to the rewind roll speed pulse tach.
The following procedure sets the outputs of the card to +10 volts at maximum machine speed.
a) Set the SW201 switches on the Power board. Refer to Section 5.20 on page 34.
