Lamp test
All display and status LED's can be illuminated simultaneously by depressing the UP and
DOWN keys at the same time. Any defective LED's will not light.
* CHANGE CHART (also see Changing Charts, Section 5.2)
If the UP and DOWN keys are held depressed for more than 2 seconds but less than 4
seconds, the display will show Cchg momentarily. The pen(s) will move to and remain at a
point above the top graduation on the chart and the chart will stop rotation to allow the chart to
be changed. The pens will remain fully upscale with the chart OFF; otherwise, the unit will
continue to operate normally in the current mode. To restore pen(s) position and chart
rotation, press the UP and DOWN keys for more than 2 seconds but less than 4 seconds.
PEN RESYNCHRONIZATION
To resynchronize the pen(s), depress the UP and DOWN keys for 4 seconds, the display will
show P dn momentarily, the pen(s) are driven to the "Pen Home" position below the bottom
graduation on the chart while the unit resynchronizes their position. After about 14 seconds,
the pen(s) will return to their correct position. All other functions of the unit's present mode
continue to operate normally.
4.5.2.1 ENTERING THE ENABLE MODE
The Enable mode is entered by pressing and holding the UP and DOWN keys simultaneously
while in the Operate or Off modes. Holding the two keys depressed for 10 seconds will cause
the display to show the EnAb prompt which is the entry point into the Enable mode.
A hardware jumper located on the Processor Board (Appendix A-1, page 46) can be used to
lock/unlock the Enable mode. When the jumper is moved to the locked position, entry into the
Enable mode is not possible until the jumper is moved to the unlock position.
4.5.3 PROGRAM MODE CONFIGURATION PROCEDURE
The Program mode provides a means to configure or reconfigure the unit operation within the
limits of the hardware specified and provided. Only those parameters that are applicable, as
determined by the hardware provided, will appear.
Review the entry procedure in 4.4.1 and the configuration procedures in Table 4-2 (page 26).
Use the "Your Setting" column in the table to record your programming.
4.5.3.1 ENTERING THE PROGRAM MODE
From the Operate or Off mode, or with any other mode code displayed, depress the SCROLL
key until Prog is displayed. This is the mode code for the Program mode. With Prog in the
top display depress the DOWN key to enter the Program mode. If the Prog code does not
appear, then the mode has been disabled. Refer to Table 4-1 (page 25) for Enable mode
instructions.
Upon entering the Program mode, PEn1 wil be displayed. The Program mode is broken into
three parts. The parameters that are associated solely with Pen 1 will be displayed in the
upper display. The parameters associated with Pen 2, will be displayed in the lower display.
The parameters that are common to both pens, such as chart rotation speed, will be displayed
in the upper display. Access to the Pen 1, Pen 2, or Unit (common) parameters may be
quickly obtained by depressing the SCROLL key, if necessary, until the desired code, PEn1 ,
PEn2 , or unit is displayed and then depressing the DOWN key. Once into the parameters,
the three parts automatically follow one another.
