Cautions on installation place   
 
Do not install the unit in a place subject to vibration, shocks and inclination. 
 
 
How to Use 
 
1. Wiring (refer to the drawing (DWG) No. 941-003)   
 
2. Replacement of chart and other preparations (refer to DWG No. 860-016 and 860-014) 
 
      (1)  Pull the pen lifting bar toward you to separate the pen from cylinder.   
 
      (2)  Pull the chart holder upward and remove used chart. (DWG No. 860-014) 
 

(3)  Wind the chart on to cylinder so that the lower edge of new chart is closely applied to the

 

bottom lip of cylinder.    Overlap both ends of chart at the chart holder and attach the chart 
holder to hold the chart (DWG No. 860-014) 

 

(4)  Pour water or oil containing little viscosity into the vessel of damper.    This is provided to

 

slow 

the pen’s descent when the pen returns to zero. (DWG No. 860-016) 

 

(5)  To move the pen position by hand, push the suction plate of solenoid 

  downward and

 

release.    Ratchet wheel 

  forwards by one tooth and the pen rises for one pulse.   

         

(DWG No. 860-016) 

 

(6)  Confirm that the pen tip is on the zero scale of chart.    If the pen tip is deviated, loosen lock 

nut 

  and make adjustments turning zero adjustment screw 

. (DWG No. 860-016) 

 

(7)  Remove cap of pen.    (Be careful not to touch the pen tip with fingers or ink will not flow 

smoothly owing to grease.) 

 

(8)  Install two C size batteries into the battery compartment on top of cylinder being careful 

about the polarity of + and - . Battery life will be about one year, however in the place where 
temperature is below 0

, its performance will drop. In such an ambient, use alkali batteries 

(DWG No. 860-014) 

 

 
(9)  Align the pen tip with the time line of chart.    Turn the cylinder seen from above 

counterclockwise so that the error by gear gap will be decreased. 

 

(10) Two 

“D” size batteries (3VDC) are used for the counter to drive the solenoid.    Install the 

batteries in the battery compartment located in the cover.    The solenoid generates noise 
and surge absorber of 22V is inserted.    (DWG No. 811-022, 941-003) 

 
3.  Change the Chart-forwarding Speed (DWG No. 860-015) 
 

There are two shafts on the bottom of the cylinder that are A (24H) for 1-day and B (168H) for 
7-day period.      Install the either of 1-day or 7-day pinion onto the proper shaft to change the 
recording period. 

 
4.  External supply of power (Refer to DWG No. 941-003) 
 

When the power is supplied from the external batteries (3 to 12VDC), be sure to remove the 
built-in batteries. 

 

The min. voltage is required so that the electric current flows within 85mA to 150mA.
