REPEATABILITY
Set point:
For accurate set-point adjustment, mount the switch on a calibration stand and
use a suitable test or reference gauge. Select your set-point by rotating the
adjustment hex clockwise or counterclockwise. Pressurize the system to the
required set-point, then lower the pressure. Adjust your set-point as required
and repeat the process four or more times to ensure repeatability.
CABLE GLAND INSTALLATION
- The explosion proof cable gland should be paired with the certified product.
- Always remember to shut off the power to the switch before wiring to avoid electric shock.
- Before wiring, ensure the installation environment is safe – free of dangerous and/or flammable gasses.
- In accordance with regulatory requirements, the cable O.D. corresponds with different materials as follows (unit = mm)
C.R
Chloroprene Rubber
(min. temp. -20t)| C20| C25| C32| C40| C45
---|---|---|---|---|---
6∼8| 10∼12| 16∼18| 22∼24| 28∼30
8∼10| 12∼14| 18∼20| 24∼26| 30∼32

CABLE GLAND INSTALLATION
After packing the cable gland, the inner Chloroprene (C.R.) rubber is not
