Rotate the pen arm on the sector gear so that the stylus (pen tip) sets on the chart plate next to the chart hub but not touching the chart hub (avoid the drive pin for the paper). Then, tighten the screw holding the pen to the sector gear. Swing the chart plate out. ATTENTION The base or bottom line of the created chart should not print over the word HONEYWELL logo on the blank chart. The base line of the created chart should not be farther than /8th of an inch away from the HONEYWELL logo. 23 Connect the stylus wires plug connector to J8 on the Main printed circuit board (just above the large capacitor near the bottom of the board - under alarm PCB, if supplied). 24 Close the chart plate and door and apply power. Align the pen as described in Subsection /07 Replacement Kit Instruction Page 5 of 7

6 4.0 One and Two Pen Classic Pen Alignment Mechanical alignment CAUTION Align pens mechanically as shown in Table4 and then electrically as described in Table 5. Never attempt to manually force the pen arms from the front, since this will damage the pen mechanism. Table 4 Pen (purple) and Pen 2 (red) Mechanical Alignment Step Action Refer to Figure 4-. ATTENTION If you only have a one pen recorder, steps for pen 2 (red) do not apply. 2 Turn off power, open the door, and lift the pen lifter up. 3 Unclip and remove the purple and red ink cartridges from pen and 2 arms to provide a better view of tips of arms. 4 Push the No. pen sector gear down so that its uppermost teeth mesh with teeth on the motor shaft gear. 5 Push the No. 2 pen sector gear up until it is at the top of the slot in the servo plate. 6 For the 2 Pen Recorder: Remove the screw and lockwasher holding the No. pen arm to the servo shaft. Slightly loosen the screw holding the No. 2 pen arm to the servo shaft. For the Pen Recorder: Slightly loosen the screw holding the No. pen arm to the servo shaft and skip to step 8. 7 Move the No. 2 pen arm so that its right tip aligns with the inside circumference of the inner most circle in the center of the chart. Tighten the screw. 8 Replace the No. pen arm, lockwasher, and screw, but leave the screw slightly loose. 9 Move the No. pen arm so that its right tip aligns with the inside circumference of the inner most circle in the center of the chart. Tighten screw. Continued on next page Page 6 of 7 Replacement Kit Instruction /07

Set LOCKOUT to NONE. ATTENTION PEN and PEN 2 must be aligned separately. However, the keystroke sequence is the same for both pens, but the prompts change from PEN to PEN 2. Be sure that the number of the pen displayed in the prompt agrees with the number of the pen being aligned. If you only have a one pen recorder, the PEN 2 prompts do not apply. Align the pens electrically as shown in Table 5. Table 5 Set the Chart Time Line Procedure Step Press Action/Result Open the door, apply power, and wait for the recorder to run its power up tests. 2 SET UP Until you see: SET UP LOCKOUT 3 FUNC Until you see: LOCKOUT One of the following NONE CALIB + CONF + VIEW MAX 4 5 or SET UP Until NONE is in the lower display.

ATTENTION You can position the pen over 200 steps. Those steps are relative units only. Step 0.0 is the inner most position on the chart, and step 200 is the highest circumference position. You will see: ALIGN PEN 0 0 The value adjusted in step 3 is entered into memory. to raise or lower the value in the upper display (up to 200) move the pen to the highest chart range value (outer circumference printed on the chart). 0 Repeat Steps 5 through 9 for PEN 2 or press LOWR DISP key to return to normal operation and enter the span value into memory. 9/07 Replacement Kit Instruction Page 9 of 7

10 5.0 Truline Printing Characteristics Adjustments Introduction With software version 005 (and newer), two different hot stylus pen designs are available; check your model number for: Table III = _0_ for high speed stylus (black tip) Table III = for abrasion resistant jewel tip stylus (beige tip) The abrasion resistant stylus is designed for recording applications that include highly abrasive environments. The abrasion resistant stylus should only be used with chart speeds from 24 hrs/rev to 3 days/rev. Configuration choices Configuration choices are now provided for PEN TYPE and the selection made must match the stylus design. PEN TYPE = NORMAL is for the high speed stylus design. PEN TYPE = JEWEL is used only for abrasion resistant stylus design. CAUTION If the JEWEL selection is accidently used with the high speed design, the life of that stylus will be shortened. Printing characteristics adjustments Normally there is no need to adjust the printing characteristics. However, if the chart printing appears to be faded, you can use the procedure in Table 6 to make slight adjustments in the print contrast for the trace and grid lines. ATTENTION To access Set-up group prompt ADJUST, the Set Up group prompt LOCKOUT must be set to NONE. If the group prompt LOCKOUT has been configured for CALIB, +VIEW, or MAX selection, you will not be able to access the Printing Characteristics Group prompt.

12 5.0 Truline Printing Characteristics Adjustments Continued Printing characteristics adjustments procedure, continued Table 6 Printing Characteristics Adjustment Procedure, continued Step Description Press Action 6 Select Stylus FUNC Until you see: NORMAL JEWEL PEN TYPE 7 Return to normal operation LOWR DISP Press or to select the pen type. Select NORMAL if high speed stylus (black tip) is installed. Select JEWEL only if abrasion resistant stylus (beige tip) is installed. Return to normal operation and observe the change in printing characteristics. Change Set Up group LOCKOUT to something other than NONE. Check pen alignment Check the pen alignment by creating a chart. The base or bottom line of the created chart should not print over the word HONEYWELL logo on the blank chart. The base line of the created chart should not be farther than /8th of an inch away from the HONEYWELL logo. ATTENTION If the alignment is incorrect, loosen the screw at the sector gear and readjust. Adjustment is linear. If the printing is too dark, repeat steps 3, 4, and 5 in Table 6. If any other problem occurs, call Honeywell Technical Assistance Center Page 2 of 7 Replacement Kit Instruction /07
