Nexen ROP 964538 - Manual (Page 10)

FORM NO. L-21200-C-0613 10
LOAD CELL SELECTION
1. Press the LOAD CELL key to display the tension for load cell 1 as indicated by “Tension1” on the RSTC Status
screen (See Figure 7).
2. Press the key a second time to display the tension for load cell 2 as indicated by “Tension2” on the RSTC screen.
3. Press the key a third time to display the total tension of load cell 1 and 2 as indicated by “Tension” on the RSTC
screen.
TAPER TENSION ADJUSTMENT
A RSTC using a roll diameter sensor is capable of performing taper tension during a roll winding application. Two adjustable
parameters are provided on the ROP for taper tension applications:
a) TAPER: determines the amount of tension taper applied to the roll
b) DELAY: determines the roll diameter at which the tension tapering is to begin
For more information on taper tensioning, refer to the RSTC instruction manual.

1. Press “TAPER +” or “TAPER –” to display the Job Setup screen. Holding down “TAPER +” or “TAPER –” will
cause the Taper value to increase (more tension taper) or decrease (less tension taper) respectively. A Taper value
of zero will turn off the taper function.
2. Release the key to return to the RSTC Status screen (there will be a short delay).

1. Press “DELAY +” or “DELAY –” to display the Job Setup screen. Holding down “DELAY +” or “DELAY –” will
cause the Delay value to increase (begin tapering later) or decrease (begin tapering sooner) respectively.
2. Release the key to return to the RSTC Status screen (there will be a short delay).
COMMUNICATION STATUS INDICATORS
Communication status between the ROP and the RSTC is indicated by the COM and ERROR indicators (See Figure
6). The COM indicator flashes whenever there is communication between both units. The ERROR indicator turns on
whenever there is a communication error detected by the ROP.
If an error is detected by the ROP, the ROP will re-send the message. If successful, the error indicator is turned off. If
the communication error is still present (and the ERROR indicator remains on) ensure that the communications cord
is firmly seated into the ROP’s connector (See Figure 4) and the communication cord connections at the RSTC are
correct (See Figure 5). Anytime the ERROR indicator is on, many of the displayed parameters will not change as they
are updated from the RSTC.
IMPERIAL OR METRIC UNITS
The ROP is capable of displaying tension and roll diameter in either imperial or metric units. Choose the desired units
during RSTC setup. Units cannot be changed from the ROP.
ROP POWER UP
When power is applied to the ROP, all job parameter settings including the ones in use prior to power removal and Job
1 through 10 parameter settings are restored. Parameters such as Automatic/Manual mode, Manual Output Level, and
Control Output on/off are updated from the RSTC.
ROLL DIAMETER
Roll diameter values are received from the RSTC and are only displayed if greater than zero.
