INTERNAL ELECTRICAL SCHEMATICS

SELECTION OF DISPLAY MULTIPLIER

  • The last digit/letter represents the selection code : Blinking red LED indicates negative pressure.
  • Diagonal column: Display multiplier cannot be selected due to resolution and number of digits.
  • (Selection code is not indicated either.)
  • Selection code is set at “1” prior to shipment.

ANALOG OUTPUT MODE

  • When shipped from our factory : 102R : V mode is set at “3” and 102A, 103R : G mode is set at “2”.
  • In case of 102R and 103R, R/G/V mode can be set at “1”, “2” or “3”
  • (However, the accuracy at V mode of 103R can’t be guaranteed). 102A : Only G mode can be set.

 

SWITCH OUTPUT MODE

  • Note 1. In the Separate Mode, setting 1 corresponds to SW1, and Setting 2 corresponds to SW2.
  • Note 2. In the Window Comparator Mode, the minimum value for SW1 and SW2 corresponds to Setting 1 and the maximum value corresponds to Setting 2.

HOW TO MOUNT OPTIONAL ACCESSORIES (Sold separately)

 

Installation

◆Tube at atmospheric pressure intake

If there is any possibility that the sensor may become wet with oil or water, which may enter the case through the air intake, connect a silicon tube, or similar, to the intake and position the end of the tube in a suitably safe place. Be sure not to bend the tube or block the end of the tube.

◆Piping

Use a wrench (13mm) on the aluminum die-casting. Do not hold the plastic case when tightening. Apply sealing tape at the male screw area to protect against air leaks. If mounting with an angled bracket, the maximum torque of the M3 screws should be less than 0.3N ·m.
When using the accessories sealing or fitting screw, bind up the seal tape around the sealing screw one and a half or two turns, and screw it in the pressure port by hand without damaging the screw thread. After then, tighten the screw sufficiently with wrench.(Recommended torque:Plastic screw 3.0N·m, Metal screw 10.0N·m maximum)
